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 It was superseded in production by the ASH 30.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 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.
