The Aeroprakt A-22 Foxbat is a Ukrainian two seat, high-wing, tricycle gear ultralight aircraft that was designed by Yuri Yakovlev and is manufactured by Aeroprakt. In the USA the A-22 is referred to as the ''Valor'',〔(Aeroprakt USA A-22 )〕 while in the UK and Australia it is called the ''Foxbat''. It has also been marketed as the ''Vision''.〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 20. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X〕〔Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 118. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X〕 The Aeroprakt A-22 is supplied either as "ready-to-fly" factory built aircraft, or as a kit,〔 consisting of some 152 pieces. The kit can be built in about 500 man-hours. The A-22 meets the definition of an FAI microlight.〔〔 ==Design and development== Aeroprakt of Kiev began design of the A-22 in February 1990, with the first prototype making its maiden flight on 21 October 1996, and a German-certified version entering production in 1999.〔Jackson 2003, p. 464.〕 The A-22's structure is almost completely all-metal with only the engine cowling, wing fillets and wheel spats being made of composites. The wings and control surfaces are fabric covered. The aircraft has excellent visibility, due to the large amount of glazing, including convex doors, that allow the occupants to look straight down. The A-22 uses a 3-axis control system, giving the pilot full control over the aircraft. The A-22 uses flaperons in place of ailerons and flaps, giving a stall speed of 52Kmh (28Kt) with the flaperons fully down.〔〔(The UK 'Foxbat' website )〕 The kit comes with either the Rotax 912UL or optionally the Rotax 912ULS. The Jabiru 2200 can also be fitted.〔〔 Originally the A-22 came fitted with a 40-litre inboard fuel tank behind the seats although later models have wing tanks holding 37.5 litres per side. The propeller is a 3-blade composite ground adjustable KievProp. Dual controls are standard, using a single central "Y" yoke or optionally twin yoke control system. 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「Aeroprakt A-22 Foxbat」の詳細全文を読む スポンサード リンク
