__NOTOC__ The Stampe et Vertongen RSV.22〔Stampe et Vertongen designated their designs with two numbers; the first signifying the wing area of the design in square metres, the second signifying the power of the engine in horsepower (Hauet 1984, p.9). Stampe et Vertongen aircraft designed by Alfred Renard gained the prefix "R" (Hauet 1984, p.7).〕 was a training biplane produced in Belgium in the 1920s.〔Taylor 1989, p.839〕〔''The Illustrated Encyclopedia of Aircraft'', p.2955〕 It was a conventional, single-bay biplane with staggered wings of unequal span that were braced with N-struts near their tips.〔Hauet 1984, p.21〕 The fixed undercarriage consisted of two mainwheels that were joined by a common through axle, plus a tailskid.〔 The student pilot and the instructor sat in open cockpits in tandem〔〔 that were fitted with dual controls.〔 Construction was of mixed materials, with metal used for the undercarriage, engine mount, and cabane struts.〔 The control surfaces were operated by a rigid linkage made of dural tube.〔 The horizontal stabilizer was adjustable in flight, using a lever in the cockpit to adjust the aircraft's trim.〔 Incorrect use of this latter feature led to a number of accidents.〔 The base model RSV 22/180 was powered by a 134-kW (180-hp) Hispano-Suiza engine, but the aircraft was designed to use powerplants of up to 220 kW (300 hp).〔 The RSV 22/200 variant used a 150-kW (200-hp) Renard-built radial engine in place of the Hispano-Suiza.〔〔 The Belgian Air Force purchased 20 examples of the RSV 22/180.〔 In 1928, Lt Edmond Thieffry and SLt Philippe Quersin piloted a civil-registered RSV 22/180 (registration ''O-BAJE'') on an attempt at a long-distance flight to Africa.〔 They departed Deurne on 26 June, attempting to reach Kinshasa.〔 Bad weather forced them to land at Mourmelon, France, only away. Resuming their journey, they were forced down a second time, this time in a marsh at Clapier, near Vauvert, still in France.〔 They abandoned the attempt at this point and successfully returned to Belgium.〔 ==Variants== ;RSV.22/180: base model with 134-kW (180-hp) Hispano-Suiza engine (over 20 built)〔 ;RSV.22/200: version with 150-kW (200-hp) Renard-built radial engine (1 built)〔 ;RSV.22 Titan:A version powered by a Gnome-Rhône 5K 5-cyl. radial engine. ;RSV.22 Lynx:A version powered by a Armstrong Siddeley Lynx 5-cyl. radial engine. 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「Stampe et Vertongen RSV.22」の詳細全文を読む スポンサード リンク
