The Airplane Factory Sling 2 is a South African two-seater light aircraft designed and produced by The Airplane Factory in Johannesburg, South Africa.〔''African Pilot'', Athol Franz, ''The Aircraft Factory Sling'', Dec 2010, Vol9-No12, pp70-71.〕 In 2009 the specially modified second prototype was flown around the world in a westerly circumnavigation which took 40 days. This was the first time any aircraft of this class had achieved a circumnavigation.〔''SA Flyer'', Guy Leitch, ''Sling around the world'', Oct 2009, No. 168, pp20-28.〕 The design complies with the requirements of four different regulatory aircraft classes. The Sling 2 is supplied as a kit and as a ready-to-fly aircraft and can be operated as a Light-sport Aircraft or homebuilt aircraft. ==Design and Development== Development of the Sling 2 commenced in 2006. The Sling is a two-seat, low wing, all metal aircraft with tricycle landing gear made from composites. The aircraft is powered by a 100 hp (75 kW) Rotax 912 ULS engine which drives a 3-bladed Warp Drive Inc propeller. The airplane features a sliding canopy, large fuel tanks, and standard equipment includes a "glass cockpit" style display.〔Bernard, Mary and Suzanne B. Bopp: ''The Airplane Factory: Sling 2 (and Sling 4)'', Kitplanes, Volume 29, Number 12, December 2012, page 22. Belvoir Publications. ISSN 0891-1851〕〔 Mike Blyth began working on the design of the Sling 2 in 2006. The first prototype was completed in 2008, the Sling made its first flight on November 18, 2008. A full testing programme followed, with the help of a South African military aerodynamicist, which was completed in 2009. Blyth and partner James Pitman then flew the 2nd prototype around the world to accomplish a challenging circumnavigation.〔 Sixty Sling 2s had been completed and flown by the end of 2012. The aircraft is now known as "Sling 2" to distinguish it from the more recent four-seat Sling 4, also in production.〔 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「The Airplane Factory Sling 2」の詳細全文を読む スポンサード リンク
