The MARVEL (Mississippi Aerophysics Research Vehicle with Extended Latitude) was a single-engined pusher monoplane fitted with a boundary layer control system. The first all-composite aircraft, it carried out its initial program of research on behalf of the US Army in the late 1960s, and was rebuilt in the 1980s as a proof-of-concept for a utility aircraft. ==Development and design== The Department of Astrophysics and Aerospace Engineering at the Mississippi State University had been involved in a program of research into boundary layer control on behalf of the Office of Naval Research and the US Army since the early 1950s, carrying out trials on a modified Schweizer TG-3 glider, a Piper L-21 and a Cessna O-1.〔〔Matt, Paul R. "(Anderson Greenwood AG-14 and the MARVEL program )". Retrieved December 31, 2009.〕 Based on the results of these studies, the US Army awarded the Department a contract to develop a new STOL research aircraft the XV-11 MARVEL ("Mississippi Aerophysics Research Vehicle, Extended Latitude").〔"(History: XV-11A Marvel )". Department of Aerospace Engineering, ''Mississippi State University''. Retrieved December 31, 2009.〕 The resultant design was a shoulder-winged monoplane powered by a single Allison T63 turboprop engine driving a pusher ducted propeller. The aircraft's structure was made completely of fiberglass, making the Marvel the first example of an all-composite aircraft.〔(【引用サイトリンク】url=http://www.msstate.edu/web/media/detail.php?id=2584 )〕 The boundary layer control system used a blower driven by the engine to draw suction through more than one million tiny holes in the wings and fuselage, while instead of conventional flaps the Marvel used a form of wing warping to deflect the wing trailing edges to vary the wing's camber.〔 The aircraft's tail surfaces were attached to the duct around the propeller, extending behind the duct. The undercarriage, of the so-called "Pantobase" configuration, with tandem wheels fitted within two sprung wooden pontoons, was meant to allow operation from rough surfaces, or even from water.〔〔Heyman 1990, p.52.〕〔Harding 1990, pp. 184–185.〕 It was constructed mainly of fiberglass, with steel used for reinforcement and as heat shields around the engine.〔Heyman 1990, p.51.〕 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「Mississippi State University XV-11 Marvel」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
