ABSTRACT:
A foot-launched and foot-landed hang glider is powered by an internal combustion two-cycle engine drivingly connected through a reduction-drive unit to a large relatively slow-moving propeller. A reduction mount, so referred to because it couples the reduction-drive unit closely to the engine, allows the engine to rotate a large propeller relatively slowly, thus providing more thrust at near-stalling flight conditions. The hang glider, thus powered, also obviates the necessity of being launched from the edge of a precipice and permits flight which is not predicated on the fortuitous selection of favorable air currents.
