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 The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingsp ...

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 The ASW 22 is an Open Class glider built by Alexander Schleicher GmbH & Co which first flew in 1981. The 'W' in the designation indicates that this is a product of the German designer Gerhard Waibel. An ASW 22 broke the world 750 km tria ...
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 Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft ...
. 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 The Wankel engine (, ) is a type of internal combustion engine using an eccentric (mechanism), eccentric Pistonless rotary engine, rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, f ...
