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 N 1 rpm, assuring greater responsiveness to control inputs.

Claims (3)

1 . A windmilling, free-air turbine external to a gas turbine engine powerplant that powers the compressor of that engine via energy taken from the relative wind passing over a vehicle in motion.

a.) where the turbine in (1) turns an electrical generator to produce electrical current to power the turbo-compressor; or,

b.) where the turbine in (1) produces the energy to power the turbocompressor, rotating it at desired operating speeds via mechanical couplings and/or clutches.
