Design and development

In 1984, designer Martin Heide (the 'H' in the type designation) combined the wing of the World Championship winning single-seater Schleicher ASW 22 [3] with a fuselage derived from the Akaflieg Stuttgart fs31 which had particularly low drag. The prototype was designated AS 22-2. [4] :2 [5] The span was increased in later versions to 25.6 or 26 metres with winglets.

A 'turbo' version was also developed, the ASH 25E, followed by the self-launching ASH 25 Mi with a large retractable propeller and a Wankel engine.
