REVERSE FLOW GAS TURBINE ENGINE HAVING ELECTRIC MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240280053 titled 'REVERSE FLOW GAS TURBINE ENGINE HAVING ELECTRIC MACHINE

The abstract describes an aircraft engine assembly that includes a gas turbine engine with an intake channel designed to receive incoming air and create an intake flow of air. The intake channel redirects the incoming air from its original direction to align with the gas turbine engine's axial direction. Additionally, an electric machine is connected to the low-pressure shaft of the engine and positioned near the intake channel's aft end. The electric machine is in heat exchange communication with the intake flow of air, allowing it to transfer heat to the incoming air within the intake channel during operation.

Original Abstract Submitted

an aircraft engine assembly includes a gas turbine engine having an intake channel configured to receive an incoming flow of air and thereby form an intake flow of air, the intake channel configured to turn the received incoming flow of air from an incoming flow direction to a first axial direction of the gas turbine engine, the incoming flow direction reverse of the first axial direction, and an electric machine coupled with the low pressure shaft and located at the aft end of the gas turbine engine proximate the intake channel, the electric machine in heat exchange communication with the intake flow of air such that the electric machine transfers heat to the incoming flow of air within the intake channel when the electric machine is operated.
