Abstract
Disclosed is a high-power electric motor and its fabrication technology. The motor and its distributed power electronics are all being fully integrated in a conventional turbofan engine. The rotor drives directly (with no gears) the LP shaft of the jet engine while requiring minimal modification to a basic jet engine and without distortion to the nacelle geometry. In principle such a configuration should be suitable for a power level of 10 to 50 MW, which makes it fully capable of providing a standard flight envelope by only using electric energy.
Claims20
1) A hybrid electric jet engine containing a jet engine coupled with at least one electric machine and its associated power-electronic, characterized by said electric machine and power-electronic being designed to fit between the inner geometry of the by-pass duct and the outer geometry of the core, while said electric machine being also coaxial with the core axis.
11) An electric machine and its associated power-electronics, wherein the improvement consists of coils with variable geometry.
18) A hybrid electric jet engine containing electric propulsive means, characterized by the dissipation of thermal losses related to said electric propulsive means and/or any other recoverable losses in the by-pass duct.
