The Wing D-1 Derringer is an American light twin-engined two-seat monoplane tourer designed by John Thorp and developed by the Hi-Shear Corporation and built by the Wing Aircraft Company. ==Development== The D-1 Derringer light twin design was originally designed in 1958 by John Thorp as the Thorp T-17 a twin-engined development of his Thorp T-11 Sky Scooter. The design was taken over by George Wing of the Hi-Shear Corporation. The Derringer is a low-wing cantilever monoplane with a retractable tricycle landing gear. It had room for two in an enclosed cockpit with an unusual up and backward opening canopy. It was powered by two 100 hp Continental O-200 engines, one mounted on the leading edge of each wing. The prototype aircraft (registered ''N3621G'') first flew on May 1, 1962〔 at Torrance. A second prototype flew in November 1964 but crashed a few weeks later due to an inflight airframe failure. A static test aircraft and two more aircraft were built for testing which resulted in the award of a type certificate on December 20, 1966.〔J W R Taylor 1982, p. 486.〕 The aircraft did not go into production due to internal problems within the Hi-Shear Corporation. The Derringer used manufacturing techniques that were considered new at the time it was developed. Butt-joined, flush-riveted, chemically-milled and stretched skins are used through the airframe. Development of a two-seat Coin/military trainer version designated Wing D-2M Derringer was begun〔J W R Taylor 1982, p. 487.〕 but failed to develop further than the design stage. In 1978 George Wing left Hi-Shear and started the Wing Aircraft Company.〔 The company built one-pre-production aircraft followed by six production aircraft, entering bankruptcy in July 1982, after which only one further aircraft was built before seven unfinished airframes were sold. Nine D-1 aircraft were on the U.S. civil aircraft register in May 2009. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wing Derringer」の詳細全文を読む スポンサード リンク
