Abstract

The invention relates to a hybrid-electric propulsion system for an aircraft, a computer-implemented method of assessing a health of a gas turbine engine of the hybrid-electric propulsion system, andan assessment control system. The method includes receiving, by one or more computing devices, data indicative of an amount of electrical power provided to, or extracted from, an electric machine. Themethod also includes receiving, by the one or more computing devices, data indicative of an operating parameter of the hybrid-electric propulsion system. The method also includes assessing, by the one or more computing devices, a health of the gas turbine engine based at least in part on the received data indicative of the amount of electrical power provided to, or extracted from, the electric machine and the received data indicative of the operating parameter of the hybrid electric propulsion system. The method also includes providing, by the one or more computing devices, information to a user indicative of the health of the gas turbine engine.

Description

technical field [0001] The present subject matter relates generally to a hybrid electric propulsion system for an aircraft, and more specifically, to a method for assessing the health of a gas turbine engine of a hybrid electric propulsion system. Background technique [0002] In at least some known engine systems, the engine is designed to operate for relatively long periods of time. During this course of operation, the engine may degrade, reducing engine performance and efficiency and / or increasing engine emissions. Once the engine has been degraded to a certain point, certain maintenance operations must be performed on the engine to restore the engine to a certain level of operability. These maintenance operations may include removing the engine from the wing and overhauling the engine. This process can be time-consuming and expensive. Therefore, it is often necessary to wait until such maintenance operations are required before performing such maintenance operations. ...
