title="Spacecraft">spacecraft</a> configuration in which the body itself produces <a href="/wiki/Lift_(force)" title="Lift (force)">lift</a>. In contrast to a <a href="/wiki/Flying_wing" title="Flying wing">flying wing</a>, which is a wing with minimal or no conventional <a href="/wiki/Fuselage" title="Fuselage">fuselage</a>, a lifting body can be thought of as a fuselage with little or no conventional <a href="/wiki/Wing" title="Wing">wing</a>. Whereas a flying wing seeks to maximize cruise efficiency at <a href="/wiki/Subsonic_flight" class="mw-redirect" title="Subsonic flight">subsonic</a> speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, <a href="/wiki/Supersonic" class="mw-redirect" title="Supersonic">supersonic</a> and <a href="/wiki/Hypersonic" class="mw-redirect" title="Hypersonic">hypersonic</a> flight, or <a href="/wiki/Spacecraft" title="Spacecraft">spacecraft</a> <a href="/wiki/Re-entry" class="mw-redirect" title="Re-entry">re-entry</a>. All of these flight regimes pose challenges for proper flight safety. </p><p>Lifting bodies were a major area of research in the 1960s and 70s as a means to build a small and lightweight crewed spacecraft. The US built a number of lifting body rocket planes to test the concept, as well as several rocket-launched re-entry vehicles that were tested over the Pacific. Interest waned as the <a href="/wiki/US_Air_Force" class="mw-redirect" title="US Air Force">US Air Force</a> lost interest in the crewed mission, and major development ended during the <a href="/wiki/Space_Shuttle_design_process" title="Space Shuttle design process">Space Shuttle design process</a> when it became clear that the highly shaped fuselages made it difficult to fit fuel tankage. </p><p>Advanced <a href="/wiki/Spaceplane" title="Spaceplane">spaceplane</a> concepts in the 1990s and 2000s did use lifting-body designs. Examples include the <a href="/wiki/HL-20_Personnel_Launch_System" title="HL-20 Personnel Launch System">HL-20 Personnel Launch System</a> (1990) and the <a href="/wiki/Prometheus_(spacecraft)" title="Prometheus (spacecraft)">Prometheus spaceplane</a> (2010). The <a href="/wiki/Dream_Chaser" title="Dream Chaser">Dream Chaser</a> lifting-body spaceplane, an extension of HL-20 technology, was proposed as one of three vehicles to potentially carry <a href="/wiki/US" class="mw-redirect" title="US">US</a> crew to and from the <a href="/wiki/International_Space_Station" title="International Space Station">International Space Station</a>, but eventually was selected as a resupply vehicle instead. In 2015 the <a href="/wiki/ESA" class="mw-redirect" title="ESA">ESA</a> <a href="/wiki/Intermediate_eXperimental_Vehicle" title="Intermediate eXperimental Vehicle">Intermediate eXperimental Vehicle</a> performed the first ever successful reentry of a lifting body spacecraft.<sup id="cite_ref-ESABulletin161_1-0" class="reference"><a href="#cite_note-ESABulletin161-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Lifting_body&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The lifting body had been imagined by 1917, in which year an aircraft with something like a delta wing plan form with a thick included fuselage was described in a patent by <a href="/wiki/Scroggs_The_Last_Laugh" title="Scroggs The Last Laugh">Roy Scroggs</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> However at low airspeeds the lifting body is inefficient and did not enter mainstream airplane design.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

A steerable spacecraft with wings could significantly extend its landing envelope. However, the vehicle's wings would have to be designed to withstand the dynamic and thermal stresses of both re-entry and hypersonic flight.

Lifting bodies were eventually rejected in favor of a delta wing design for the Space Shuttle. Data acquired in flight test using high-speed landing approaches at very steep descent angles and high sink rates was used for modeling Shuttle flight and landing profiles. </p><p>In planning for atmospheric re-entry, the landing site is selected in advance. For reusable reentry vehicles, typically a primary site is preferred that is closest to the launch site in order to reduce costs and improve launch turnaround time. However, weather near the landing site is a major factor in flight safety. In some seasons, weather at landing sites can change quickly relative to the time necessary to initiate and execute re-entry and safe landing. Due to weather, it is possible the vehicle may have to execute a landing at an alternate site. Furthermore, most airports do not have runways of sufficient length to support the approach landing speed and roll distance required by spacecraft. Few airports exist in the world that can support or be modified to support this type of requirement. Therefore, alternate landing sites are very widely spaced across the U.S. and around the world. The Shuttle's delta wing design was driven by these issues. These requirements were further exacerbated by requirements that extended the Shuttle's flight landing envelope. </p><p>Nonetheless, the lifting body concept has been implemented in a number of other <a href="/wiki/Aerospace" title="Aerospace">aerospace</a> programs, the previously mentioned <a href="/wiki/NASA_X-38" title="NASA X-38">NASA X-38</a>, <a href="/wiki/Lockheed_Martin_X-33" title="Lockheed Martin X-33">Lockheed Martin X-33</a>, <a href="/wiki/British_Aircraft_Corporation" title="British Aircraft Corporation">BAC</a>'s <a href="/wiki/Multi_Unit_Space_Transport_And_Recovery_Device" class="mw-redirect" title="Multi Unit Space Transport And Recovery Device">Multi Unit Space Transport And Recovery Device</a>, Europe's <a href="/wiki/EADS_Phoenix" class="mw-redirect" title="EADS Phoenix">EADS Phoenix</a>, and the joint Russian-European <a href="/wiki/Kliper" title="Kliper">Kliper</a> spacecraft.

Some of the early 1930s high-wing monoplane designs of the <a href="/wiki/Bellanca_Aircraft_Company" class="mw-redirect" title="Bellanca Aircraft Company">Bellanca Aircraft Company</a>, such as the <a href="/wiki/Bellanca_Aircruiser" title="Bellanca Aircruiser">Bellanca Aircruiser</a>, had vaguely airfoil-shaped fuselages capable of generating some lift, with even the wing struts on some versions given widened fairings to give them some lift-generating capability. The <a href="/wiki/Gee_Bee_Model_R" class="mw-redirect" title="Gee Bee Model R">Gee Bee R-1 Super Sportster</a> racing plane of the 1930s, likewise, from more modern aerodynamic studies, has been shown to have had considerable ability to generate lift with its fuselage design, important for the R-1's intended racing role, while in highly banked pylon turns while racing.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Vincent_Burnelli" title="Vincent Burnelli">Vincent Burnelli</a> developed several aircraft between the 1920s and 1950 that used fuselage lift. Like the earlier Bellanca monoplanes, the <a href="/wiki/Short_SC.7_Skyvan" title="Short SC.7 Skyvan">Short SC.7 Skyvan</a> produces a substantial amount of lift from its fuselage shape, almost as much as the 35% each of the wings produces. </p><p>Fighters like the <a href="/wiki/F-15_Eagle" class="mw-redirect" title="F-15 Eagle">F-15 Eagle</a> also produce substantial lift from the wide fuselage between the wings. Because the F-15 Eagle's wide fuselage is so efficient at lift, an F-15 is able to land successfully with only one wing, albeit under nearly full power, with thrust contributing significantly to lift. In the summer of 1983, an Israeli F-15 staged a mock dogfight with Skyhawks for training purposes, near Nahal Tzin in the Negev desert. During the exercise, one of the Skyhawks miscalculated and <a href="/wiki/1983_Negev_mid-air_collision" title="1983 Negev mid-air collision">collided forcefully with the F-15's wing root</a>. The F-15's pilot was aware that the wing had been seriously damaged, but decided to try and land in a nearby airbase, not knowing the extent of his wing damage. It was only after he had landed, when he climbed out of the cockpit and looked backward, that the pilot realized what had happened: the wing had been completely torn off the plane, and he had landed the plane with only one wing attached. A few months later, the damaged F-15 had been given a new wing, and returned to operational duty in the squadron. The engineers at McDonnell Douglas had a hard time believing the story of the one-winged landing: as far as their planning models were concerned, this was an impossibility.<sup id="cite_ref-noWingF15_11-0" class="reference"><a href="#cite_note-noWingF15-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> </p><p>In 2010, <a href="/wiki/Orbital_Sciences" class="mw-redirect" title="Orbital Sciences">Orbital Sciences</a> proposed the <a href="/wiki/Prometheus_(spacecraft)" title="Prometheus (spacecraft)">Prometheus</a> "blended lifting-body" <a href="/wiki/Spaceplane" title="Spaceplane">spaceplane</a> vehicle, about one-quarter the size of the <a href="/wiki/Space_Shuttle" title="Space Shuttle">Space Shuttle</a>, as a <a href="/wiki/Private_spaceflight" title="Private spaceflight">commercial</a> option for carrying astronauts to <a href="/wiki/Low_Earth_orbit" title="Low Earth orbit">low Earth orbit</a> under the <a href="/wiki/CCDev" class="mw-redirect" title="CCDev">commercial crew program</a>.<sup id="cite_ref-osc2011_7-1" class="reference"><a href="#cite_note-osc2011-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> The <a href="/wiki/VTVL#Other_approaches" title="VTVL">Vertical Takeoff, Horizontal Landing</a> (VTHL) vehicle was to have been launched on a human-rated <a href="/wiki/Atlas_V" title="Atlas V">Atlas V</a> rocket but would land on a runway.<sup id="cite_ref-wsj20101214_12-0" class="reference"><a href="#cite_note-wsj20101214-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> The initial design was to have carried a crew of 4, but it could carry up to 6, or a combination of crew and cargo.
