The Scheibe Specht ((英語:Woodpecker)) is a tandem seat training glider produced in Germany in the early 1950s. More than fifty were built. ==Design and development== The Specht was designed by Rudolph Kaiser, who around 1952 was dividing his time between Scheibe in Dachau and Schleicher in Poppenhausen. Hence the Specht and its contemporary Schleicher Ka-4 Rhönlerche, also designed by Kaiser, have much in common.〔 The Specht has a wooden, two spar, high wing, braced on each side by V-struts from the spars to the lower fuselage, jury struts and mounted with 2° of dihedral. There is plywood skinning from the leading edge to the rear spar on the upper surface and to the forward spar below. The leading edge of the wing is straight and unswept and the trailing edge is parallel to it over its inner section, becoming tapered outboard. Ailerons, with inset hinges, fill these sections. Spoilers are mounted in the mid-inner wing panels at 11% chord.〔 Scheibe used their usual fabric covered, steel tube and wooden stringer construction for the fuselage. Pupil and instructor sit in tandem in an enclosed cockpit, with the rear seat accessed by an under wing door. The fuselage, flat sided and hexagonal in section, narrows to the conventional tail. The horizontal tail, mounted on top of the fuselage, is roughly rectangular in plan and of low aspect ratio and the fin and rudder together are straight tapered and flat topped. The rudder is hinged behind the elevators and extends down to the keel. The Specht lands on a fixed monowheel under the rear seat, assisted by a central skid. The Specht prototype first flew in March 1953. Just three years (7 March 1956) later Scheibe flew the Sperber ((英語:Sparrowhawk)), a side by side seat version.〔 Necessarily wider in the cockpit area, the two types differed little, though the Sperber's span was greater and it was slightly () heavier. Their performances were also very similar; the Sperber's minimum sink rate was 7% greater.〔 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「Scheibe Specht」の詳細全文を読む スポンサード リンク
