Abstract: A hybrid aerodynamic thrust system as a prime mover for aircraft or other high-speed vehicles. An arrangement of dual thrust resources to alternately accommodate low and high airspeed regimes. Electromotive force is used in lieu of hot section power turbines to achieve engine air compression or alternately perform thrust work at low velocities.

Abstract: An alternate means of generating the power to drive the compressor section of gas turbine engines is described. Electric motors embedded within gas turbines would rotate the compressor, and receive the requisite power to perform the compression work from: 1) either a high-capacity APU generator, or 2) from a relative-wind driven turbine in a hybrid power-sharing arrangement. The electric motor provides enhanced control of N1 rpm, assuring greater responsiveness to control inputs.
