An experimental study was carried out which has led to the determination of a transpiration flow characteristics in the form of a simple formula that is very useful in modelling such flows. In connection to this relation a method of "aerodynamic porosity" determination has been proposed which is much more reliable than geometric description of the porosity.

An experimental study was carried out which has led to the determination of a transpiration flow characteristics in the form of a simple formula that is very useful in modelling such flows. In connection to this relation a method of \"aerodynamic porosity\" determination has been proposed which is much more reliable than geometric description of the porosity. A theoretical analysis of the flow through a perforation hole was also carded out. The flow was considered as compressible and viscous.

A commercial software ANSYS Fluent was used for these numerical simulations to calculate the aerodynamic characteristics of 2-D NACA-4312 airfoil at different angles of attack (α) at fixed Reynolds number (Re), equal to 5 × 10 5. These simulations were solved using two different turbulence models, one was the Standard − model with enhanced wall treatment and other was the SST − model. Numerical results demonstrate that both models can produce similar results with little deviations. It was observed that both lift and drag coefficient increase at higher angles of attack, however lift coefficient starts to reduce at α =13° which is known as stalling condition. Numerical results also show that flow separations start at rare edge when the angle of attack is higher than 13° due to the reduction of lift coefficient.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/44276404" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="82b5d44b93c32cf6f0d588c3ed2630e7" rel="nofollow" data-download="{"attachment_id":64654640,"asset_id":44276404,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/64654640/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="77135558" href="https://independent.academia.edu/RhyhanulIslam">Rhyhanul Islam</a><script data-card-contents-for-user="77135558" type="text/json">{"id":77135558,"first_name":"Rhyhanul","last_name":"Islam","domain_name":"independent","page_name":"RhyhanulIslam","display_name":"Rhyhanul Islam","profile_url":"https://independent.academia.edu/RhyhanulIslam?f_ri=10875","photo":"https://0.academia-photos.com/77135558/20123959/19874660/s65_rhyhanul.islam.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-44276404">+1</span><div class="hidden js-additional-users-44276404"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://kuet.academia.edu/MohammadIliasInam">Mohammad Ilias Inam</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-44276404'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-44276404').html();

Numerical results also show that flow separations start at rare edge when the angle of attack is higher than 13° due to the reduction of lift coefficient.","downloadable_attachments":[{"id":64654640,"asset_id":44276404,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":77135558,"first_name":"Rhyhanul","last_name":"Islam","domain_name":"independent","page_name":"RhyhanulIslam","display_name":"Rhyhanul Islam","profile_url":"https://independent.academia.edu/RhyhanulIslam?f_ri=10875","photo":"https://0.academia-photos.com/77135558/20123959/19874660/s65_rhyhanul.islam.jpg"},{"id":103688653,"first_name":"Mohammad Ilias","last_name":"Inam","domain_name":"kuet","page_name":"MohammadIliasInam","display_name":"Mohammad Ilias Inam","profile_url":"https://kuet.academia.edu/MohammadIliasInam?f_ri=10875","photo":"https://0.academia-photos.com/103688653/38984429/32422032/s65_mohammad_ilias.inam.jpg"}],"research_interests":[{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics?f_ri=10875","nofollow":true},{"id":61709,"name":"Computational Fluid Dynamics (CFD) modelling and simulation","url":"https://www.academia.edu/Documents/in/Computational_Fluid_Dynamics_CFD_modelling_and_simulation?f_ri=10875","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_7729835" data-work_id="7729835" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/7729835/_my_final_yr_project_AERO_DYNAMIC_DRAG_REDUCTION_IN_BLUNT_NOSE_CONE_USING_AN_AERO_SPIKE">(my final yr project) AERO DYNAMIC DRAG REDUCTION IN BLUNT NOSE CONE USING AN AERO SPIKE </a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">High-speed flow over a blunt body generates a bow shock wave which causes high surface pressure and as a result the development of high aerodynamic drags.

Tasarım süreçleri esnasında MARTOY dikkate alınmış ve bütün düzenlemeler buna göre yapılmıştır. Bilgisayar ortamında tasarıma başlanmadan önce farklı kabin eskizleri üzerinde durulmuş ve boğa figüründen esinlenilerek tasarım yapılmıştır. El çizimlerinin ardından bilgisayar ortamında solidworks programı ile üç boyutlu tasarımlarına başlanmıştır. Bu bağlamda, kabin karoseri, dorse, koltuk, direksiyon, dikiz aynaları gibi kamyonun başlıca parçaları standartlarına uygun bir biçimde tasarlanmıştır. Tasarlanan bu parçalar yine Solidworks'un montaj modülünde olması gereken ilişkiler verilerek montajlanmıştır. Böylelikle analize uygun hale getirilmiştir. Yine Solidworks akış analizi modülü ile tasarımların, hava akışına maruz bırakılarak basınç, hız ve sıcaklık analizleri yapılmıştır.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/25705039" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="d88616bbc02115733cef63792c1e4e53" rel="nofollow" data-download="{"attachment_id":46049684,"asset_id":25705039,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46049684/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="48675549" href="https://gazi.academia.edu/OrhanT%C3%BCrk">Orhan TÜRK</a><script data-card-contents-for-user="48675549" type="text/json">{"id":48675549,"first_name":"Orhan","last_name":"TÜRK","domain_name":"gazi","page_name":"OrhanTürk","display_name":"Orhan TÜRK","profile_url":"https://gazi.academia.edu/OrhanT%C3%BCrk?f_ri=10875","photo":"https://0.academia-photos.com/48675549/12808233/31875905/s65_orhan.t_rk.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-25705039">+1</span><div class="hidden js-additional-users-25705039"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/AzizKaanY%C4%B0%C4%9E%C4%B0T">Aziz Kaan YİĞİT</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-25705039'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-25705039').html();

Tasarım süreçleri esnasında MARTOY dikkate alınmış ve bütün düzenlemeler buna göre yapılmıştır. Bilgisayar ortamında tasarıma başlanmadan önce farklı kabin eskizleri üzerinde durulmuş ve boğa figüründen esinlenilerek tasarım yapılmıştır. El çizimlerinin ardından bilgisayar ortamında solidworks programı ile üç boyutlu tasarımlarına başlanmıştır. Bu bağlamda, kabin karoseri, dorse, koltuk, direksiyon, dikiz aynaları gibi kamyonun başlıca parçaları standartlarına uygun bir biçimde tasarlanmıştır. Tasarlanan bu parçalar yine Solidworks'un montaj modülünde olması gereken ilişkiler verilerek montajlanmıştır. Böylelikle analize uygun hale getirilmiştir. Yine Solidworks akış analizi modülü ile tasarımların, hava akışına maruz bırakılarak basınç, hız ve sıcaklık analizleri yapılmıştır.","downloadable_attachments":[{"id":46049684,"asset_id":25705039,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":48675549,"first_name":"Orhan","last_name":"TÜRK","domain_name":"gazi","page_name":"OrhanTürk","display_name":"Orhan TÜRK","profile_url":"https://gazi.academia.edu/OrhanT%C3%BCrk?f_ri=10875","photo":"https://0.academia-photos.com/48675549/12808233/31875905/s65_orhan.t_rk.jpg"},{"id":49410141,"first_name":"Aziz Kaan","last_name":"YİĞİT","domain_name":"independent","page_name":"AzizKaanYİĞİT","display_name":"Aziz Kaan YİĞİT","profile_url":"https://independent.academia.edu/AzizKaanY%C4%B0%C4%9E%C4%B0T?f_ri=10875","photo":"https://0.academia-photos.com/49410141/16309872/38232968/s65_aziz_kaan.yi_i_t.jpeg"}],"research_interests":[{"id":988,"name":"Design","url":"https://www.academia.edu/Documents/in/Design?f_ri=10875","nofollow":true},{"id":3952,"name":"Industrial Design","url":"https://www.academia.edu/Documents/in/Industrial_Design?f_ri=10875","nofollow":true},{"id":5079,"name":"Graphic Design","url":"https://www.academia.edu/Documents/in/Graphic_Design?f_ri=10875","nofollow":true},{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics?f_ri=10875","nofollow":true},{"id":47297,"name":"Automotive Engineering","url":"https://www.academia.edu/Documents/in/Automotive_Engineering?f_ri=10875"},{"id":104745,"name":"3d Modeling","url":"https://www.academia.edu/Documents/in/3d_Modeling?f_ri=10875"},{"id":258385,"name":"Automotive Technology","url":"https://www.academia.edu/Documents/in/Automotive_Technology?f_ri=10875"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_11174652" data-work_id="11174652" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/11174652/Aircraft_Design_Projects_For_Engineering_Students_by_J_R_Jenkinson_J_F_Marchman">Aircraft Design Projects For Engineering Students by J.R.

Numerous techniques such as suction at slots, flaps, bumps, high lift devices etc. have been developed by the scientists to control the separation delay and thereby prevent the aerodynamic losses at higher angles of attack. This research work aims at studying the effects of delaying the boundary layer separation by adopting blowing active flow control with local jets with varying velocity ratios and at different angles of attack on a 2D NACA 0084M aerofoil. Four different ratios of jet velocity (viz., 1, 2, 6 and 12) have been considered and the aerodynamic performance of each has been evaluated. The research aims to focus on the improvements in lift and drag characteristics of the above-mentioned aerofoil and identify the best possible jet velocity. I. INTRODUCTION The bird has been man's inspiration to build a machine which can fly. Engineers soon realized that the cross-section of a bird's wings and the body was identified and were enthralled by the fact that it was this profile (aerofoil) which made the bird fly great heights. The National Advisory Committee for Aeronautics (NACA) soon carried out experimental analysis of various aerofoils which revolutionized aerospace industry. The aerospace industry has diversified and modern defense and commercial flights are being designed to reach greater performance levels as compared to their 20 th-century counterparts.

Lift and drag are two aerodynamic loads which influence the performance of any aerospace machine. Engineers around the world have been relentlessly trying to get the maximum lift with minimum drag and have designed numerous devices which take machines closer to this ideal situation.

The rotor was the same one tested during the landmark 1993 NASA/Army UH-60A Airloads flight test and included a highly pressure-instrumented blade to measure rotor airloads. This paper provides an overview of the wind tunnel test, including detailed descriptions of the hardware, instrumentation, and data acquisition and reduction systems.

Here the Onera-M6 wing is modelled for the transonic flow conditions in 3D with the adiabatic flow conditions. In the first case only the Onera-M6 wing is analyzed to know the performance. In the second case the canard is considered along with the Onera-M6 main wing and the modelling is done with the same set of conditions as 3D- transonic flows. In the present study two canard positions are considered, one under the same axis of the main wing (20% shrinkage), and another above the axis line of the main wing (20% shrinkage-offset). In the first design i.e., canard of 20% shrinkage with same axis, the design is performing well than clean wing & 20% shrinkage-offset canard at the lower angle of attacks.

Here the Onera-M6 wing is modelled for the transonic flow conditions in 3D with the adiabatic flow conditions. In the first case only the Onera-M6 wing is analyzed to know the performance. In the second case the canard is considered along with the Onera-M6 main wing and the modelling is done with the same set of conditions as 3D- transonic flows. In the present study two canard positions are considered, one under the same axis of the main wing (20% shrinkage), and another above the axis line of the main wing (20% shrinkage-offset). In the first design i.e., canard of 20% shrinkage with same axis, the design is performing well than clean wing \u0026 20% shrinkage-offset canard at the lower angle of attacks.

This paper presents the estimation and selection of aircraft design parameters, planform design, reflex airfoils, and conduct thorough stability investigation of the aircraft. A conceptual design of BWB aircraft has been done and the design was analyzed and refined to achieve static stability. The CFD analysis of the BWB aircraft was done at three different values of angle-of-attack (AOA) and thus the stall AOA was determined from the computational results. The dynamic stability of the aircraft has been studied under five modes namely-short period, phugoid, Dutch-roll, roll and spiral. The static stability has been achieved with a wide positive value of static margin. Results also show that the aircraft is dynamically stable for longitudinal and lateral modes when subjected to disturbances in respective conditions. The BWB aircraft fulfils the criteria of Class I Category B aircraft and shows flight level 1 characteristics in all stability modes.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/76670332" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="f120aa2a48326b499764285e34a1a66f" rel="nofollow" data-download="{"attachment_id":84301255,"asset_id":76670332,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/84301255/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="20979746" href="https://tribhuvan.academia.edu/SanjivPaudel">Sanjiv Paudel</a><script data-card-contents-for-user="20979746" type="text/json">{"id":20979746,"first_name":"Sanjiv","last_name":"Paudel","domain_name":"tribhuvan","page_name":"SanjivPaudel","display_name":"Sanjiv Paudel","profile_url":"https://tribhuvan.academia.edu/SanjivPaudel?f_ri=10875","photo":"https://0.academia-photos.com/20979746/5800941/11274964/s65_sanjiv.paudel.jpg"}</script></span></span></li><li class="js-paper-rank-work_76670332 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="76670332"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 76670332, container: ".js-paper-rank-work_76670332", });

This paper presents the estimation and selection of aircraft design parameters, planform design, reflex airfoils, and conduct thorough stability investigation of the aircraft. A conceptual design of BWB aircraft has been done and the design was analyzed and refined to achieve static stability. The CFD analysis of the BWB aircraft was done at three different values of angle-of-attack (AOA) and thus the stall AOA was determined from the computational results. The dynamic stability of the aircraft has been studied under five modes namely-short period, phugoid, Dutch-roll, roll and spiral. The static stability has been achieved with a wide positive value of static margin. Results also show that the aircraft is dynamically stable for longitudinal and lateral modes when subjected to disturbances in respective conditions. The BWB aircraft fulfils the criteria of Class I Category B aircraft and shows flight level 1 characteristics in all stability modes.","downloadable_attachments":[{"id":84301255,"asset_id":76670332,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":20979746,"first_name":"Sanjiv","last_name":"Paudel","domain_name":"tribhuvan","page_name":"SanjivPaudel","display_name":"Sanjiv Paudel","profile_url":"https://tribhuvan.academia.edu/SanjivPaudel?f_ri=10875","photo":"https://0.academia-photos.com/20979746/5800941/11274964/s65_sanjiv.paudel.jpg"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering?f_ri=10875","nofollow":true},{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=10875","nofollow":true},{"id":88,"name":"Aerospace Engineering","url":"https://www.academia.edu/Documents/in/Aerospace_Engineering?f_ri=10875","nofollow":true},{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics?f_ri=10875","nofollow":true},{"id":1006024,"name":"Computational Fluids Dynamics (CFD)","url":"https://www.academia.edu/Documents/in/Computational_Fluids_Dynamics_CFD_?f_ri=10875"},{"id":1938464,"name":"Mechanical Engineering-Biomedical applications","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering-Biomedical_applications?f_ri=10875"},{"id":2164933,"name":"Blended Wing Body","url":"https://www.academia.edu/Documents/in/Blended_Wing_Body?f_ri=10875"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_37178983" data-work_id="37178983" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/37178983/Meetings_by_G_K_Korotkov">Meetings by G.K.

Four different cases were investigated: an air-fired and three different oxy-fuel combustion environments (25 vol.% O 2 concentration (OF25), 27 vol.% O 2 concentration (OF27), and 29 vol.% O 2 concentration (OF29) were considered. The chemical reactions (devolatilization and char burnout), convective and radiative heat transfer, fluid and particle flow fields (homogenous and heterogenous processes), and turbulent models were employed in 3-D hybrid unstructured grid CFD simulations. The available experimental results from a lab-scale 100 KW firing lignite unit (Chalmer's furnace) were selected for the validation of these simulations. The aerodynamic effect of primary and secondary registers of the burner was included through swirl at the burner inlet in order to achieve the flame stability inside the furnace. Validation and comparison of all the combustion cases with the experimental data were made by using the temperature distribution profiles and species concentration (O 2 , CO 2 , and H 2 O) profiles at the most intense combustion locations of the furnace. The overall visualization of the flame temperature distributions and oxygen concentrations were presented in the upper part of the furnace. The numerical results showed that the flame temperature distributions and O 2 consumptions of the OF25 case were approximately similar to the reference combustion case. In contrast, in the OF27 and OF29 combustion cases, the flame temperatures were higher and more confined in the closest region of the burner exit plane. This was a result of the quick consumption of oxygen that led to improve the ignition conditions in the latter combustion cases. Therefore, it is concluded that the resident time, stoichiometry, and recycled flue gas rates are relevant parameters to optimize the design of oxy-fuel furnaces. The findings showed reasonable agreement with the qualitative and quantitative measurements of temperature distribution profiles and species concentration profiles at the most intense combustion locations inside the furnace. These numerical results can provide useful information towards future modelling of the behaviour of pulverized brown coal in a large-scale oxy-fuel furnace/boiler in order to optimize the burner's and combustor's design.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/31290479" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b38676c459c98e1d33d5a7df26631602" rel="nofollow" data-download="{"attachment_id":51688521,"asset_id":31290479,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/51688521/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="9372399" href="https://unnes.academia.edu/JamalNaser">Jamal Naser</a><script data-card-contents-for-user="9372399" type="text/json">{"id":9372399,"first_name":"Jamal","last_name":"Naser","domain_name":"unnes","page_name":"JamalNaser","display_name":"Jamal Naser","profile_url":"https://unnes.academia.edu/JamalNaser?f_ri=10875","photo":"https://0.academia-photos.com/9372399/3565422/4184304/s65_jamal.naser.jpg"}</script></span></span></li><li class="js-paper-rank-work_31290479 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="31290479"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 31290479, container: ".js-paper-rank-work_31290479", });

Four different cases were investigated: an air-fired and three different oxy-fuel combustion environments (25 vol.% O 2 concentration (OF25), 27 vol.% O 2 concentration (OF27), and 29 vol.% O 2 concentration (OF29) were considered. The chemical reactions (devolatilization and char burnout), convective and radiative heat transfer, fluid and particle flow fields (homogenous and heterogenous processes), and turbulent models were employed in 3-D hybrid unstructured grid CFD simulations. The available experimental results from a lab-scale 100 KW firing lignite unit (Chalmer's furnace) were selected for the validation of these simulations. The aerodynamic effect of primary and secondary registers of the burner was included through swirl at the burner inlet in order to achieve the flame stability inside the furnace. Validation and comparison of all the combustion cases with the experimental data were made by using the temperature distribution profiles and species concentration (O 2 , CO 2 , and H 2 O) profiles at the most intense combustion locations of the furnace. The overall visualization of the flame temperature distributions and oxygen concentrations were presented in the upper part of the furnace. The numerical results showed that the flame temperature distributions and O 2 consumptions of the OF25 case were approximately similar to the reference combustion case. In contrast, in the OF27 and OF29 combustion cases, the flame temperatures were higher and more confined in the closest region of the burner exit plane. This was a result of the quick consumption of oxygen that led to improve the ignition conditions in the latter combustion cases. Therefore, it is concluded that the resident time, stoichiometry, and recycled flue gas rates are relevant parameters to optimize the design of oxy-fuel furnaces. The findings showed reasonable agreement with the qualitative and quantitative measurements of temperature distribution profiles and species concentration profiles at the most intense combustion locations inside the furnace. These numerical results can provide useful information towards future modelling of the behaviour of pulverized brown coal in a large-scale oxy-fuel furnace/boiler in order to optimize the burner's and combustor's design.","downloadable_attachments":[{"id":51688521,"asset_id":31290479,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":9372399,"first_name":"Jamal","last_name":"Naser","domain_name":"unnes","page_name":"JamalNaser","display_name":"Jamal

A swirl injection system is used to achieve the flame stability of the turbulent non-premixed combustible gases. An Eddy Breakup (EBU) combustion model with appropriate empirical coefficients is employed for this study. Validation and comparison of both combustion cases with the experimental data, which conducted on a 100 kW facility unit, were made by comparing the temperature distribution levels and species concentration levels. The oxy-fuel combustion case showed that the flame is obviously concentrated in the central region, and it is not spread inside the furnace compared to the air-fired flame. The swirl effect is certainly used to enhance the turbulent mixing and to achieve the internal recirculation of flames.

Conversely, the flow features along the cylinder lateral surfaces and, hence, the lift are strongly sensitive to setup and modelling, leading to a significant dispersion of both wind tunnel measurements and numerical predictions.

Early investigations included the study of boundary layer energization by means of a small flapping foil embedded in a flat-plate boundary layer, the reduction of the recirculatory flow region behind a backward-facing step by means of a small flapping foil, and the reduction or suppression of flow separation behind blunt or cusped airfoil trailing edges by flapping a small foil located in the wake flow region. These studies were followed by systematic investigations of the aerodynamic characteristics of single flapping airfoils and airfoil combinations. These unsteady flows were described using flow visualization, laser-Doppler velocimetry in addition to panel and Navier-Stokes computations. It is then shown how this flapping-wing database was used to conceive, design and develop a micro air vehicle which has a fixed wing for lift and two flapping wings for thrust generation. While animal flight is characterized by a coupled force generation, the present design appears to separate lift and thrust. However, in fact, the performance of one surface is closely coupled to the other surfaces.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/62520271" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="2da9c582926179f24796f35a999ce07c" rel="nofollow" data-download="{"attachment_id":75253908,"asset_id":62520271,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/75253908/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="202923368" href="https://independent.academia.edu/maxplatzer">max platzer</a><script data-card-contents-for-user="202923368" type="text/json">{"id":202923368,"first_name":"max","last_name":"platzer","domain_name":"independent","page_name":"maxplatzer","display_name":"max platzer","profile_url":"https://independent.academia.edu/maxplatzer?f_ri=10875","photo":"https://0.academia-photos.com/202923368/63969655/52284101/s65_max.platzer.jpeg"}</script></span></span></li><li class="js-paper-rank-work_62520271 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="62520271"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 62520271, container: ".js-paper-rank-work_62520271", });

aircraft except gliders have enormous turbulence losses during flight.  Gliders are only excepted because they fly so slow that better airflow patterns exist, where less turbulence occurs, and that the effects of turbulence regarding energy goes as the second power of airspeed.  An aircraft flying at 500 mph has around 400 times more aerodynamic (drag) energy losses than if the same size-and-shape glider was flying at 25 mph. <br />An Active Skin technology has been invented, TURCAN, where the vast majority of turbulence is eliminated.  Theoretically, total aerodynamic drag might be reduced to 1/7 current drag factors, meaning that fuel would then last around 7 times as long or as far! <br /> <br /> <br /> <br /> <br />More practically, this new TURCAN technology should be able to reduce total aircraft drag to about half of current levels.  This would DOUBLE fuel economy.  Instead of an airline having to buy $120,000 of jet fuel for a specific trip, maybe only $60,000 would need to be bought!  Then, with the gross airframe weight being 150,000 pounds less at takeoff (due to not needing to load those thousands of extra gallons of Jet Fuel) the overall efficiency would be even greater than that! <br />Below, reference is made to the US government spending millions of dollars to try to improve overall efficiency by 1.5%, several years ago.  Interesting, since they never showed any interest in THIS TURCAN technology which would CERTAINLY improve efficiency by 50% and probably 100% or more! <br /> <br />For the hundred years of powered flight, it has always been accepted that very large amounts of drag from air turbulence was unavoidable.  This fact is closely related to the fact that virtually all aircraft are designed to use BOTH of two very different methods of creating Lift, called Bernoulli Lift and Reaction Lift, and the Reaction Lift is notoriously bad regarding creating massive turbulence and loss.  There appears to be a method, TURCAN, to meta-stably eliminate most of that turbulence, and therefore most of the drag which must be overcome.  The result would be extremely efficient flight, using far less than half as much aviation fuel to accomplish the same performance, and possibly less than one-fourth as much fuel consumption, without otherwise changing performance. <br />Powered aircraft must produce forward "thrust" to overcome rearward "drag" and then also be able to accelerate forward.  The forward thrust also enables aerodynamic lift to occur, which balances the weight of the aircraft.  Much of the drag that exists that is associated with airfoils (wings) is due to turbulence that develops along the top of airfoil and behind the airfoil surface.  In many situations regarding Bernoulli Lift, around 6/7 of the total drag is due to this turbulence, with only 1/7 actually being unavoidable. <br />Until now, very sleek airfoil shapes and relatively thin wings have been the standard ways of trying to minimize this turbulence effect.  However, these sleek shapes also necessarily have less Bernoulli lift effect, due to standard physics and aerodynamic reasons. <br />Another trend in modern aviation is due to the enormous power now available in aircraft engines.  It is the reliance on a second manner of lift, "reaction lift".  This type of lift is entirely due to the wing surface being tilted, so that oncoming air is deflected down by impact against the bottom of the wing.  This is simple Newtonian action-and-reaction.  Massive amounts of air is given a downward Momentum, which again according to Newton, necessarily creates an upward Momentum to the wing structures.  Unfortunately, that type of lift creates even more drag due to massive turbulence behind and above the wing surface.  With plenty of power available, that is not a problem, but it causes much more consumption of jet fuel.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div

In the context of event detection, it is a major source of false alarms. There is a strong need from the security industry either to detect and suppress these false alarms, or dampen the effects of background changes, so as to increase the sensitivity to meaningful events of interest. In this paper, we restrict our focus to one of the most common causes of dynamic background changes: that of swaying tree branches and their shadows under windy conditions. Considering the ultimate goal in a video analytics pipeline, we formulate a new dynamic background detection problem as a signal processing alternative to the previously described but unreliable computer vision-based approaches. Within this new framework, we directly reduce the number of false alarms by testing if the detected events are due to characteristic background motions. In addition, we introduce a new dataset suitable for the evaluation of dynamic background detection. It consists of real-world events detected by a commercial surveillance system from two static surveillance cameras. The research question we address is whether dynamic background can be detected reliably and efficiently using simple motion features and in the presence of similar but meaningful events such as loitering. Inspired by the tree aerodynamics theory, we propose a novel method named local variation persistence (LVP), that captures the key characteristics of swaying motions. The method is posed as a convex optimization problem whose variable is the local variation. We derive a computationally efficient algorithm for solving the optimization problem, the solution of which is then used to form a powerful detection statistic. On our newly collected dataset, we demonstrate that the proposed LVP achieves excellent detection results and outperforms the best alternative adapted from existing art in the dynamic background literature.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9776672" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b33bf956f73a950329b515a629e8504f" rel="nofollow" data-download="{"attachment_id":35954286,"asset_id":9776672,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/35954286/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="3275555" href="https://st-andrews.academia.edu/OgnjenArandjelovic">Ognjen Arandjelovic</a><script data-card-contents-for-user="3275555" type="text/json">{"id":3275555,"first_name":"Ognjen","last_name":"Arandjelovic","domain_name":"st-andrews","page_name":"OgnjenArandjelovic","display_name":"Ognjen Arandjelovic","profile_url":"https://st-andrews.academia.edu/OgnjenArandjelovic?f_ri=10875","photo":"https://0.academia-photos.com/3275555/4831927/5562055/s65_ognjen.arandjelovic.jpg"}</script></span></span></li><li class="js-paper-rank-work_9776672 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9776672"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9776672, container: ".js-paper-rank-work_9776672", });

literature.","downloadable_attachments":[{"id":35954286,"asset_id":9776672,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":3275555,"first_name":"Ognjen","last_name":"Arandjelovic","domain_name":"st-andrews","page_name":"OgnjenArandjelovic","display_name":"Ognjen

This paper gives an overview about UAV (Unmanned Aerial Vehicle) systems and their application for photogrammetric recording and documentation of cultural heritage. First the historical development of UAV systems and the definition of UAV-helicopters will be given. The advantages of a photogrammetric system on-board a model helicopter will be briefly discussed and compared to standard aerial and terrestrial photogrammetry. UAVs are mostly low cost systems and flexible and therefore a suitable alternative solution compared to other mobile mapping systems. A mini UAV-system was used for photogrammetric image data acquisition near Palpa in Peru. A settlement from the 13 th century AD, which was presumably used as a mine, was flown with a model helicopter. Based on the image data, an accurate 3D-model will be generated in the future. With an orthophoto and a DEM derived from aerial images in a scale of 1:7 000, a flight planning was build up. The determined flying positions were implemented in the flight control system. Thus, the helicopter is able to fly to predefined pathpoints automatically. Tests in Switzerland and the flights in Pinchango Alto showed that using the built-in GPS/INS-and stabilization units of the flight control system, predefined positions could be reached exactly to acquire the images. The predicted strip crossings and flying height were kept accurately in the autonomous flying mode.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/73533104" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b7cddc7d70b5b1789a8d062f2d99f341" rel="nofollow" data-download="{"attachment_id":82019291,"asset_id":73533104,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/82019291/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="66897707" href="https://independent.academia.edu/AhmetEdip">Edip Ahmet</a><script data-card-contents-for-user="66897707" type="text/json">{"id":66897707,"first_name":"Edip","last_name":"Ahmet","domain_name":"independent","page_name":"AhmetEdip","display_name":"Edip Ahmet","profile_url":"https://independent.academia.edu/AhmetEdip?f_ri=10875","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_73533104 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="73533104"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 73533104, container: ".js-paper-rank-work_73533104", });

The predicted strip crossings and flying height were kept accurately in the autonomous flying mode.","downloadable_attachments":[{"id":82019291,"asset_id":73533104,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":66897707,"first_name":"Edip","last_name":"Ahmet","domain_name":"independent","page_name":"AhmetEdip","display_name":"Edip Ahmet","profile_url":"https://independent.academia.edu/AhmetEdip?f_ri=10875","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":261,"name":"Geography","url":"https://www.academia.edu/Documents/in/Geography?f_ri=10875","nofollow":true},{"id":2132,"name":"Cultural Heritage","url":"https://www.academia.edu/Documents/in/Cultural_Heritage?f_ri=10875","nofollow":true},{"id":3641,"name":"Aeronautical Engineering","url":"https://www.academia.edu/Documents/in/Aeronautical_Engineering?f_ri=10875","nofollow":true},{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics?f_ri=10875","nofollow":true},{"id":11975,"name":"Peru","url":"https://www.academia.edu/Documents/in/Peru?f_ri=10875"},{"id":12105,"name":"Aeronautics and Aerospace Operations","url":"https://www.academia.edu/Documents/in/Aeronautics_and_Aerospace_Operations?f_ri=10875"},{"id":14668,"name":"Aerospace","url":"https://www.academia.edu/Documents/in/Aerospace?f_ri=10875"},{"id":104336,"name":"Data acquisition","url":"https://www.academia.edu/Documents/in/Data_acquisition?f_ri=10875"},{"id":277273,"name":"Flight Control","url":"https://www.academia.edu/Documents/in/Flight_Control?f_ri=10875"},{"id":479634,"name":"UAV DYNAMICS","url":"https://www.academia.edu/Documents/in/UAV_DYNAMICS?f_ri=10875"},{"id":781524,"name":"Precision Farming","url":"https://www.academia.edu/Documents/in/Precision_Farming?f_ri=10875"},{"id":1303555,"name":"Unmanned Aerial Vehicle","url":"https://www.academia.edu/Documents/in/Unmanned_Aerial_Vehicle?f_ri=10875"},{"id":2085770,"name":"Image Acquisition","url":"https://www.academia.edu/Documents/in/Image_Acquisition?f_ri=10875"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_71799772" data-work_id="71799772" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/71799772/A_peak_factor_for_non_Gaussian_response_analysis_of_wind_turbine_tower">A peak factor for non-Gaussian response analysis of wind turbine tower</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Equivalent static wind load evaluation formulas considering the dynamic effects based on peak factor were proposed to estimate the design wind load on the wind turbine tower in complex terrain.

A generic approach is followed to understand and mimic the mechanism and kinematics of ornithopter by considering the motion of a three-dimensional rigid thin wing in flapping and pitching motion, using strip theory and two-dimensional unsteady aerodynamics for idealized wing in pitching and flapping oscillations with phase lag. Parametric study is carried out to obtain the lift, drag, and thrust characteristics within a cycle for assessing the plausibility of the aerodynamic model, and for the synthesis of a Flapping Wing MAV model with simplified mechanism. Other important parameters such as flapping frequency and wing geometry are considered.

A generic approach is followed to understand and mimic the mechanism and kinematics of ornithopter by considering the motion of a three-dimensional rigid thin wing in flapping and pitching motion, using strip theory and two-dimensional unsteady aerodynamics for idealized wing in pitching and flapping oscillations with phase lag. Parametric study is carried out to obtain the lift, drag, and thrust characteristics within a cycle for assessing the plausibility of the aerodynamic model, and for the synthesis of a Flapping Wing MAV model with simplified mechanism. Other important parameters such as flapping frequency and wing geometry are considered.

We show some numerical results testing several rotor configurations working under different wind scenarios.","downloadable_attachments":[{"id":47316770,"asset_id":10537623,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":25819813,"first_name":"Alejandro","last_name":"Daniel","domain_name":"independent","page_name":"AlejandroDaniel5","display_name":"Alejandro Daniel","profile_url":"https://independent.academia.edu/AlejandroDaniel5?f_ri=10875","photo":"https://0.academia-photos.com/25819813/7074785/7972538/s65_alejandro.daniel.jpg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=10875","nofollow":true},{"id":2738,"name":"Renewable Energy","url":"https://www.academia.edu/Documents/in/Renewable_Energy?f_ri=10875","nofollow":true},{"id":2798,"name":"Wind Energy","url":"https://www.academia.edu/Documents/in/Wind_Energy?f_ri=10875","nofollow":true},{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics?f_ri=10875","nofollow":true},{"id":57254,"name":"Wind Power","url":"https://www.academia.edu/Documents/in/Wind_Power?f_ri=10875"},{"id":59770,"name":"Trajectory","url":"https://www.academia.edu/Documents/in/Trajectory?f_ri=10875"},{"id":65140,"name":"Models","url":"https://www.academia.edu/Documents/in/Models?f_ri=10875"},{"id":69575,"name":"Wind turbine","url":"https://www.academia.edu/Documents/in/Wind_turbine?f_ri=10875"},{"id":85294,"name":"Computer Model","url":"https://www.academia.edu/Documents/in/Computer_Model?f_ri=10875"},{"id":104318,"name":"Vertical Axis Wind Turbine","url":"https://www.academia.edu/Documents/in/Vertical_Axis_Wind_Turbine?f_ri=10875"},{"id":951218,"name":"Wind Power Plant","url":"https://www.academia.edu/Documents/in/Wind_Power_Plant?f_ri=10875"},{"id":1237788,"name":"Electrical And Electronic Engineering","url":"https://www.academia.edu/Documents/in/Electrical_And_Electronic_Engineering?f_ri=10875"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_64015897" data-work_id="64015897" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/64015897/Aerodynamics_Design_of_a_Motor_Tricycle">Aerodynamics Design of a Motor Tricycle</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This work is on the aerodynamics design of the body and frame of a motor tricycle using SolidWorks 2011 modeling system.

The stability and convergence proofs are given and experimental results with real A380 flight data are presented.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/2490757" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3d6b6f828330f794db1c0ab978faea2d" rel="nofollow" data-download="{"attachment_id":50601418,"asset_id":2490757,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50601418/download_file?st=MTc0MDE1MjEzNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="46264" href="https://uanl.academia.edu/Efra%C3%ADnAlcortaGarc%C3%ADa">Efraín Alcorta García</a><script data-card-contents-for-user="46264" type="text/json">{"id":46264,"first_name":"Efraín","last_name":"Alcorta García","domain_name":"uanl","page_name":"EfraínAlcortaGarcía","display_name":"Efraín Alcorta García","profile_url":"https://uanl.academia.edu/Efra%C3%ADnAlcortaGarc%C3%ADa?f_ri=10875","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_2490757 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="2490757"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 2490757, container: ".js-paper-rank-work_2490757", });
