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 triangle speed record in 1985 and ASW 22s have won first place in six World Gliding Championships.

Design
The ASW 22 is the successor to the ASW 17. It first flew as a 22-metre glider. The span was later increased to 25 metres for the ASW 22B with a modified inner wing section and flaperons similar to the ASW 20. It uses a Horstmann and Quast wing profile on the inner section with underwing tubes to collect high-pressure air which is then expelled through turbulator holes in the bottom wing skin ahead of the flap and aileron hinge line to prevent the separation of the laminar flow. The ASW 22 has a two-wheel retractable undercarriage.
