Abstract
An electric propulsion system for a gas turbine engine may comprise an electric motor disposed within a nacelle of the gas turbine engine, wherein the electric motor is configured to receive a bypass air from a fan bypass duct for cooling the electric motor and the electric motor is configured to drive a low speed shaft of the gas turbine engine.
Claims20
An electric propulsion system for a gas turbine engine, comprising:
- an electric motor disposed within a nacelle of the gas turbine engine;
- wherein the electric motor is configured to receive a bypass air from a fan bypass duct for cooling the electric motor and the electric motor is configured to drive a low speed shaft of the gas turbine engine.
A gas turbine engine, comprising:
- a nacelle at least partially defining a fan bypass duct;
- a low speed shaft configured to rotate about a longitudinal axis of the gas turbine engine;
- and
- an electric propulsion system, comprising:
- an electric motor disposed within the nacelle;
- wherein the electric motor is configured to receive a bypass air from the fan bypass duct for cooling the electric motor and the electric motor is configured to drive the low speed shaft.
