title="McDonnell Douglas F/A-18 Hornet">McDonnell Douglas F/A-18 Hornet</a>. Active Aeroelastic Wing Technology is a technology that integrates wing aerodynamics, controls, and structure to harness and control wing <a href="/wiki/Aeroelasticity" title="Aeroelasticity">aeroelastic</a> twist at high speeds and dynamic pressures. By using multiple leading and trailing edge controls like "aerodynamic tabs", subtle amounts of aeroelastic twist can be controlled to provide large amounts of wing control power, while minimizing maneuver air loads at high wing strain conditions or aerodynamic drag at low wing strain conditions. This program was the first full-scale proof of AAW technology. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Development">Development</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Boeing_X-53_Active_Aeroelastic_Wing&action=edit&section=1" title="Edit section: Development"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Development of the initial concept was done with wind-tunnel testing in the mid 1980s under Air Force contract.<sup id="cite_ref-redesignation_1-0" class="reference"><a href="#cite_note-redesignation-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The designation "X-52" was skipped in sequence to avoid confusion with Boeing's <a href="/wiki/B-52_Stratofortress" class="mw-redirect" title="B-52 Stratofortress">B-52 Stratofortress</a> bomber.<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> </p><p>The pre-production version of the F/A-18 was an ideal aircraft for proving AAW technology, a relatively high wing aspect ratio for a fighter, with adequate strength, but no additional stiffness needed to be added to change its twisting behaviour.

In particular, almost all modern aircraft use some form of <a href="/wiki/Leading_edge_slats" class="mw-redirect" title="Leading edge slats">slat</a> along the wing <a href="/wiki/Leading_edge" title="Leading edge">leading edge</a> to provide more lift during certain portions of flight. By deploying the slats at the same time as the ailerons their twisting effect on the main structural parts of the wing, oppose one another which eliminates the twisting. This improves the ability of the ailerons to produce large rolling moments on the aircraft. This means that less aileron deflection is needed to produce a required motion, which, in turn, will reduce <a href="/wiki/Aileron_drag" class="mw-redirect" title="Aileron drag">aileron drag</a> and its associated unwanted tendency to cause the aircraft to <a href="/wiki/Aircraft_principal_axes" title="Aircraft principal axes">yaw</a>. </p><p>If the controls can be used to eliminate the twisting and its negative effects on control input, the next step is to deliberately introduce some twisting which adds to the effect of the control deflection. When applied correctly, the wing will twist less and in an opposite direction to a conventional wing during maneuvering.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> So this change, which can be accomplished in software, benefits overall performance. </p> <div class="mw-heading mw-heading2"><h2 id="Flight_testing">Flight testing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Boeing_X-53_Active_Aeroelastic_Wing&action=edit&section=2" title="Edit section: Flight testing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><span><video id="mwe_player_1" poster="//upload.wikimedia.org/wikipedia/commons/thumb/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv/220px--F-18A_Active_Aeroelastic_Wing_flight_test.ogv.jpg" controls="" preload="none" data-mw-tmh="" class="mw-file-element" width="220" height="165" data-durationhint="31" data-mwtitle="F-18A_Active_Aeroelastic_Wing_flight_test.ogv" data-mwprovider="wikimediacommons" resource="/wiki/File:F-18A_Active_Aeroelastic_Wing_flight_test.ogv"><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv/F-18A_Active_Aeroelastic_Wing_flight_test.ogv.360p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="360p.vp9.webm" data-width="480" data-height="360" /><source src="//upload.wikimedia.org/wikipedia/commons/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv" type="video/ogg; codecs="theora, vorbis"" data-width="480" data-height="360" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv/F-18A_Active_Aeroelastic_Wing_flight_test.ogv.360p.webm" type="video/webm; codecs="vp8, vorbis"" data-transcodekey="360p.webm" data-width="480" data-height="360" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv/F-18A_Active_Aeroelastic_Wing_flight_test.ogv.144p.mjpeg.mov" type="video/quicktime" data-transcodekey="144p.mjpeg.mov" data-width="192" data-height="144" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/1/17/F-18A_Active_Aeroelastic_Wing_flight_test.ogv/F-18A_Active_Aeroelastic_Wing_flight_test.ogv.240p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="240p.vp9.webm" data-width="320" data-height="240" /></video></span><figcaption>X-53 Active Aeroelastic Wing (AAW) flight test, March 2005</figcaption></figure> <p>To test the AAW theory, NASA and the USAF agreed to fund development of a single demonstrator, based on the F/A-18.

Active aeroelastic wing control laws were developed to flex the wing, and flight instrumentation was used to accurately measure the aeroelastic performance of the <a href="/wiki/Wing_planform" class="mw-redirect" title="Wing planform">wing planform</a>.
