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 brake flaps.
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 18hp 2-stroke engine.

Famous quotes containing the words design and/or development:
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
“If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.”
—Arthur Miller (b. 1915)
