Embodiment Construction

[0038] Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. The detailed description uses numerical and letter designations to refer to features in the drawings. The same or similar symbols have been used in the drawings and the specification to designate the same or similar parts of the present invention.

[0039] As used herein, the terms "first", "second" and "third" are used interchangeably to distinguish one component from another and are not intended to indicate the position or importance of the various components.

[0040] The terms "forward" and "aft" refer to relative positions within the gas turbine engine or vehicle, and to the normal operating attitude of the gas turbine engine or vehicle. For example, with respect to a gas turbine engine, front refers to a location closer to the engine inlet, while aft refers to a location closer to the engine nozzle or exhaust.

Abstract

A method is provided for maintaining a gas turbine engine installed on an aircraft, the gas turbine engine including an electric machine mounted at least partially inward of a core air flowpath of thegas turbine engine. The method includes removing a rotor mount connecting a rotor of the electric machine to a rotary component of the gas turbine engine; removing a stator mount connecting a statorof the electric machine to a stationary component of the gas turbine engine; and removing in situ the electric machine.

Description

technical field [0001] The subject matter generally relates to a gas turbine engine with an embedded electric machine, and a propulsion system for an aircraft including the gas turbine engine. Background technique [0002] A typical aircraft propulsion system includes one or more gas turbine engines. For certain propulsion systems, a gas turbine engine typically includes a fan and a core arranged in flow communication with each other. Additionally, the core of a gas turbine engine typically includes a compressor section, a combustion section, a turbine section, and an exhaust section in series flow order. In operation, air is supplied from a fan to the inlet of the compressor section where one or more axial compressors progressively compress the air until it reaches the combustion section. Fuel is mixed with compressed air and combusted in the combustion section to provide combustion gases. Combustion gases are routed from the combustion section to the turbine section. T...
