The TeST TST-10 Atlas is a single-seat, standard class sailplane, with a 15 m (49 ft 3 in) wingspan, manufactured by TeST Gliders in The Czech Republic. It is available both as a pure glider (TST-10) and self-launching glider (TST-10M).〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 136-137. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X〕 ==Design and development== The TST-10M Atlas was designed for recreational, club-class flying, enhanced by the convenience of self-launching. It is made mostly of composite structure. The fuselage is made in the negative mould together with the fin. The wings also use composite material and have no ribs within the wing. Early iterations of the Atlas utilized a wooden spar of built-up construction; current versions utilize a carbon fiber spar. The typical sailplane monowheel landing gear is fixed; a castering tailwheel and wingtip wheels assist powered taxiing. Assembly of the glider is typical of modern gliders, with forked wing spars joined by two steel pins. The wings each weigh only 32 kg (71 lb). The self-launching version is powered by a 30 kW (40 hp) Rotax 447 engine externally mounted on a retractable mast which drives a two-bladed wooden propeller. Engine extension and retraction is performed by an electric motor. The published glide ratio of the Atlas is 40:1. Best glide speed is 88 km/h (55 mph, 48 kn); VNE is low for a contemporary glider at 180 km/h (110 mph, 97 kn). An improved variant, the TST-10MB was released in spring 2008. It differences from the original TST-10M in having a retractable undercarriage, automatic connection of controls for wing to fuselage assembly, a new seat shape, a larger fuel tank and optimized winglets. 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「TeST TST-10 Atlas」の詳細全文を読む スポンサード リンク
