Glider with sail-cloth lift surface - has outlets in top surface, increasing speed of air flow

摘要

The glider has a lift surface of sail cloth, and one or more outlets (5) in the top profiled surface. An air flow passes through the outlets and is directed over the surface. Then it provides additional flow energy increasing the speed of flow over the surface. The outlet(s) is pref. formed by a series of adjacent holes in the sail cloth, or alternately a net incorporated in the latter. USE/ADVANTAGE - For parachutes, gliders, hang-gliders etc, with improved safety and lift.
