Editing Autogyro (section)

=== Postwar developments ===

The autogyro was resurrected after World War{{nbsp}}II when Dr. [[Igor Bensen]], a Russian immigrant in the United States, saw a captured German U-boat's [[Focke-Achgelis Fa 330|Fa{{nbsp}}330 gyroglider]] and was fascinated by its characteristics. At work, he was tasked with the analysis of the British military [[Rotachute]] gyro glider designed by an expatriate Austrian, [[Raoul Hafner]]. This led him to adapt the design for his purposes and eventually market the [[Bensen B-7]] in 1955. Bensen submitted an improved version, the [[Bensen B-8M]], for testing to the [[United States Air Force]], which designated it the X-25.<ref name=x25>{{cite web |url = https://history.nasa.gov/monograph31.pdf#page=34 |first1 = Dennis R. |last1 = Jenkins |first2 = Tony |last2 = Landis |first3 = Jay |last3 = Miller |title = Bensen Aircraft Corporation X-25 |page = 33 |work = American X-vehicles: an inventory, X-1 to X-50 |publisher = [[NASA]] |date = June 2003 |access-date = 18 February 2012 |archive-url = https://web.archive.org/web/20200425225303/https://history.nasa.gov/monograph31.pdf#page=34 |archive-date = 25 April 2020 |url-status = dead }}</ref> The B-8M was designed to use surplus [[McCulloch Motors Corporation|McCulloch]] engines used on flying unmanned [[target drone]]s.

[[Ken Wallis]] developed a miniature autogyro craft, the [[Wallis WA-116 Agile|''Wallis'' autogyro]], in England in the 1960s, and autogyros built similar to Wallis' design appeared for many years. Ken Wallis' designs have been used in various scenarios, including military training, police reconnaissance, and in a search for the [[Loch Ness Monster]], as well as an appearance in the 1967 James Bond movie ''[[You Only Live Twice (film)|You Only Live Twice]]''.

Three different autogyro designs have been certified by the [[Federal Aviation Administration]] for commercial production: the Umbaugh U-18/[[Air & Space 18A]] of 1965, the [[Avian 2/180 Gyroplane]] of 1967, and the [[McCulloch J-2]] of 1972. All have been commercial failures, for various reasons.

The [[Kaman KSA-100 SAVER]] (Stowable Aircrew Vehicle Escape Rotorseat) is an aircraft-stowable gyroplane escape device designed and built for the [[United States Navy]]. Designed to be installed in [[Naval aviation|naval combat aircraft]] as part of the ejection sequence, only one example was built and it did not enter service. It was powered by a [[Williams F107|Williams WRC-19]] [[turbofan]] making it the first jet-powered autogyro.
