The ASW 22 Open Class is a successor to the ASW 17. It first flew on 8 July 1981 as a 22-metre glider. The span was 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.
