Design and development
The ASW 28 is a single-seat shoulder-winged composite construction sailplane with a T-shaped horizontal tailplane and 15 metre wingspan. The upper wing surface has Schempp-Hirth airbrakes.
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. The sustainer uses a SOLO 2350 18 hp two-stroke engine.
