The Schleicher Ka-2 Rhönschwalbe is a tandem two-seat training glider designed and built in Germany, in 1952. ==Design and development== Designed by Rudolf Kaiser, the Ka-2 was an all wooden glider with plywood and aircraft fabric covering. The Ka-2s wings, with marked forward sweep and dihedral are mounted above the fuselage, flanking the rear cockpit. The front cockpit is covered by a one piece plexiglas canopy which opens to the right and the rear cockpit is covered by a canopy incorporating the inner leading edges of the wing, opening rear-wards, held in place by the front canopy when closed. The undercarriage of the Ka-2 comprises a large rubber-sprung wooden skid under the forward fuselage in front of a non-retractable semi recessed mainwheel, as well as a steel rubber-sprung tail-skid. Conventional controls are fitted with ailerons on each wingtip trailing edge, elevator with anti-balance trim tab behind the tailplane and rudder aft of the fin. Schempp-Hirth airbrakes, at 38% chord and approx ⅓ span, open out above and below the wing to provide approach control.〔 Performance of the Ka-2 was found to be lower than expected, due to the relatively high wing loading. Schleicher introduced the Ka2b, increasing the wingspan from to , to improve the efficiency of the wing. Fuselage length was also increased by to to maintain stability margins in pitch.〔 Performance of the Ka-2b was improved in weak thermals due to a lower minimum sink speed, allowing tighter thermalling. Cross-country performance was also improved by a higher glide ratio, increasing the chance of reaching the next thermal. The standard competition handicap for the Ka–2 is 74 and the Ka-2b handicap is 78.〔 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「Schleicher Ka 2 Rhönschwalbe」の詳細全文を読む スポンサード リンク
