Schleicher ASW 28

Schleicher ASW 28


The ASW 28 is a Standard Class glider with a fifteen metre span built of modern fibre reinforced composites. The manufacturer of the ASW-28 is Alexander Schleicher GmbH & Co. The 'W' indicates this is a design of the influential and prolific German designer Gerhard Waibel. Serial production started in 2000.

As all Standard Class sailplanes, the ASW-28 does not have flaps or other lift-enhancing devices. It has tall winglets, a retractable undercarriage and a water ballast system. The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic. This permits a light structure with the strength to carry large amounts of water ballast, thus permitting the widest possible range of wing loadings for weak and strong soaring weather.

The ASW-28 supersedes the ASW 24 in the manufacturer's production line. It has - like its competitors Rolladen-Schneider LS8 and Schempp-Hirth Discus-2 - a version with wing extensions for the increasingly popular 18 metre Class, the ASW 28-18. The sustainer (non-self-launching) variant of the 18 metre version is the ASW 28-18 E.
