Designed by Gerhard Waibel and built in Poppenhausen, Germany, the Schleicher ASW 28 is a Standard Class glider with a laminar wing profile for "turbulent" conditions. By using carbonfibre and Aramid along with a new Polyethylene fibre, joining a high strength with low weight, Schleicher tries to achieve an empty weight of only 325 kg, and a wing loading of only 30 kg/sq.m. Four integrated tanks for a maximum water ballast of 180 liters keep the spectrum at a 50 kg/sq.m wing loading open.
The ASW 24 derived fuselage is designed to be fitted with a rescue system. The ASW 28 features a new profile from Professor Loek Boermans, which is supposed to give the new glider a top performance and excellent handling characteristics in turbulent air.
