Abstract

An airborne centrifugally stiffened and cyclically controlled system which uses airfoils which rotate around a central hub, similar to the mechanics of an autogyro. The airfoils may achieve speeds significantly above the wind speed feeding the system. The airfoils may be linked to the central hub by flexible radial tethers which stiffen considerably as the speed of the airfoil increases, or may be linked to the central hub by rigid radial links. The central hub may be linked to the ground with an extendible main tether. Power generation turbines may reside on the airfoils and utilize the high apparent wind speed for power generation. The generated power may travel down the radial tethers and across a rotating power conduit to the main tether and to the ground. The system may use autorotation, similar to the mechanics of an autogyro. Power generation turbines may reside on the blades and utilize the high apparent wind speed for power generation with little or no need for gearing between the generator blades and the generator.
