Abstract
A through-flow gas turbine engine includes a core comprising multiple spools rotatable about a center axis. An accessory gearbox (AGB) is drivingly engaged to the core and disposed aft of the outlet. A reduction gearbox (RGB) is drivingly engaged to the core and disposed forward of the inlet. The RGB has an RGB output to provide rotational output to a rotatable load. An electric motor is drivingly engaged to the rotatable load. An electric generator is configured to provide electrical power to the electric motor. the electric motor and the electric generator are disposed axially adjacent one another, and axially between the outlet and the AGB.
Claims10
A through-flow gas turbine engine, comprising:
- a core comprising multiple spools rotatable about a center axis of the gas turbine engine, each spool configured to extract energy from combustion gases, air and combustion gases configured to flow through the core in an aft direction from an air inlet at a forward end of the core to an outlet at an aft end of the core;
- an accessory gearbox (AGB) drivingly engaged to the core and disposed aft of the outlet, the AGB coaxial to the center axis and driving one or more accessories;
- a reduction gearbox (RGB) coaxial to the center axis and drivingly engaged to the core and disposed forward of the inlet, the RGB having an RGB output to provide rotational output to a rotatable load;
- and
- an electric motor drivingly engaged to the rotatable load, and
- an electric generator drivingly engaged to the core and configured to provide electrical power to the electric motor, the electric motor and the electric generator disposed axially adjacent one another, and disposed coaxially with the center axis between the outlet and the AGB.
