Schleicher ASH 25

The ASH 25 is a two-seater high performance Open Class glider manufactured by Alexander Schleicher from 1986 until September 2008, originally with a 25 metre wingspan. It was superseded in production by the ASH 30.
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 with a fuselage derived from the Akaflieg Stuttgart fs31 which had particularly low drag. The prototype was designated AS 22-2. 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.
