The ASW-12 is the production development of the trend setting Akaflieg D-36. At one time the ASW- 12 held all three world distance records. A fiberglass design featuring camber-changing flaps, the –12 had no dive brakes; early examples lacked the later added (and at first non- jettisonable) tail chute for glidepath control, a feature which…
The 15 m. racing class successor to the ASW-20 has been designed to maximize performance without regard to possible span extension or addition of an engine. Airbrakes are top surface triple element Schempp-Hirth type to compensate for the very thin wing section.
The ASW-24, which first flew in 1987, is the Standard Class successor to the Schleicher ASW- 19. Approach control is effected by top surface Schempp-Hirth type airbrakes. Designer Waibel won the 1992 OSTIV Award for significant contributions to safety for the ASW-24 design. The ASW-24E is the self-launching version for which specifications ar given in…
The Open Class successor to the Schleicher ASW- 17, the ASW-22 first flew in 1981 as a 22 m. ship, of which 39 were produced. Span on the ASW- 22B model was increased to 25 m. with a modified inner wing section and flaperons similar to the ASW-20. It uses Horstmann and Quast airfoil technology…
The ASW-20 first flew in 1977 and was an instant success, winning numerous world and national championships. Built for the 15 m. racing class, it features trailing edge flaps which interconnect with the ailerons and allow the entire trailing edge to operate as a flap between –9 and +5 degrees. The flaps also act as…
The ASW-19 succeeded the ASW-15 as Schleicher’s Standard Class Sailpane using a somewhat thinner airfoil than the model it raplaced. The airbrake operates on the upper wing surface only. Bear Selen of the Netherlands won the Standard Class at the 1978 World Championships flying an ASW-19. The Royal Air Force uses 5 ASW-19’s (known as…
The ASW-17 was the second of Gerhard Waibel’s Open Class designs, superseding the ASW-12. Aluminum double segment airbrakes make for much easier approach and landing. The four-piece wing, only 4.5 inches deep at the root, has provision for up to 100 kg./ 220 lb. Of water ballast and a four-setting flap/ aileron system in which…
The ASW-15, which first flew in 1968, was Schleicher’s first composite Standard Class design, originally appearing with a fixed wheel and no water ballast in conformity with the then Standard Class rules. It has an all-moving horizontal tail and metal airbrakes for glidepath control. With the modification of the Standard Class rules to allow water…
Caproni ( which built its first glider in 1908 at Vizzola Ticino, Italy ) produced the first A-21 in 1970, and within two years had collected four world multi-place sailplane speed and distance records with it. A 2-place all-metal ship with a fiberglass forward fuselage, the A-21 was followed into production by the slightly improved…
