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.
Claims18
A hybrid electric jet engine containing;
- a jet engine coupled with at least one electric machine, the electric machine is connected with power-electronics, characterized by;
- said electric machine and power-electronics being coaxially located with a core of the jet engine inside a mid-box structure,
- the electric machine and power-electronics are further located between a by-pass duct and the outer geometry of the core,
- with said electric machine driving directly a LP shaft.
An electric machine and its associated power-electronics comprising, coils with variable geometry and,
- said associated power-electronics has a donut shape coaxial with the electric machine and the donut shaped power-electronics fit between the inner geometry of a jet engine by-pass duct and the outer geometry of the jet engine core,
- said associated power-electronics comprises a plurality of power modules characterized by each module consisting of one or more inverters.
A hybrid electric jet engine containing;
- at least one electric machine and its associated power-electronics characterized by the dissipation of thermal losses related to said electric machine and recoverable losses in the by-pass duct wherein,
- a fan booster boosted by circulating coolant and a surface cooler that are able to dissipate the heat losses related to said electric machine and its associated power-electronics without introducing supplementary air-flow and pressure losses in the by-pass duct.
