{{Main article|Flexible wing}}

In flexible wings, also known as "morphing aerofoils", much or all of a wing surface can change shape in flight to deflect air flow much like an [[ornithopter]]. [[Adaptive compliant wing]]s are a military and commercial effort.<ref>{{citation |last=Scott |first=William B. |title=Morphing Wings |newspaper=Aviation Week & Space Technology |date=27 November 2006 |url=http://www.aviationweek.com/aw/ |access-date=2011-04-26 |archive-url=https://web.archive.org/web/20110426122028/http://www.aviationweek.com/aw/ |archive-date=2011-04-26 |url-status=live }}</ref><ref>{{cite web|url=http://www.flxsys.com/aerospace.shtml |title=FlexSys Inc.: Aerospace |access-date=26 April 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110616074103/http://www.flxsys.com/aerospace.shtml |archive-date=16 June 2011 }}</ref><ref>{{cite web|url=http://www.flxsys.com/pdf/NATO_Conf_Paper-KOTA.pdf |title=Mission Adaptive Compliant Wing – Design, Fabrication and Flight Test |first1=Sridhar |last1=Kota |first2=Russell |last2=Osborn |first3=Gregory |last3=Ervin |first4=Dragan |last4=Maric |first5=Peter |last5=Flick |first6=Donald |last6=Paul |publisher=FlexSys Inc., Air Force Research Laboratory |location=Ann Arbor, MI; Dayton, OH, U.S.A. |access-date=26 April 2011 |url-status=dead |archive-url=https://web.archive.org/web/20120322211547/http://www.flxsys.com/pdf/NATO_Conf_Paper-KOTA.pdf |archive-date=22 March 2012 }}</ref> The [[X-53 Active Aeroelastic Wing]] was a US Air Force, [[NASA]], and [[Boeing]] effort. Notable efforts have also been made by FlexSys, who have conducted flight tests using flexible aerofoils retrofitted to a Gulf stream III aircraft.<ref>{{Cite web|title=FlexFoil|url=https://www.flxsys.com/flexfoil|access-date=2022-01-22|website=FlexSys|language=en-US}}</ref>
