history

The Schleicher ASW 24 was founded in 1987 by Gerhard Waibel as the successor of Schleicher ASW 19 for the FAI - standard class developed. The ASW 24B has a modified wing profile in the nose area, a modified canopy contour and a gear box that has been moved a few centimeters to the rear, which creates more space in the cockpit. The Pole Frantisek Kepka won the European Championship in 1992 with an ASW 24 and the 1st Women's World Championship in 2001 was won by the Englishwoman Sarah Steinberg with an ASW 24.

The motorized ASW 24 E had its maiden flight in February 1988.

construction

The Schleicher ASW 24 is a mid-decker in FRP construction with retractable landing gear and water ballast tanks in the wings. It meets the requirements of the FAI - standard class . The fuselage was completely redeveloped with knowledge from the universities in Braunschweig and Delft. Particular attention was paid to the development of a safety cockpit that absorbs most of the energy in the event of an accident. For this, Gerhard Waibel received the coveted OSTIV Prize in 1993 . The gain in mechanical strength was bought, among other things, by a raised canopy frame, which, however, limits the view to the outside and is criticized by pilots. The wings were designed in collaboration with the universities of Delft and Eindhoven. They are equipped with brake flaps that extend on the top . The T-tail consists of the damped horizontal tail with spring trim and the vertical tail . A grinding spur or a star wheel are optionally available.
