摘要： A hybrid-electric propulsion system 50 for an aircraft 10 includes a turbomachine 102, the turbomachine 102 including a first spool 124 and a second spool 122. A method 400 of operating the hybrid-electric propulsion system includes operating at 402, by one or more computing devices, the turbomachine such that the first spool mechanically drives a prime propulsor of the hybrid-electric propulsion system; and modifying at 404, by the one or more computing devices, a speed relationship parameter defined between the first spool and second spool by providing electrical power to, or drawing electrical power from, an electric machine mechanically coupled to the first spool, the second spool, or both.

摘要： A compressor water-wash advisory system (302) generates compressor water-wash notifications or initiates on-line water-wash cycles for a gas turbine or turbofan jet engine based on monitored health parameters of the engine. A high-fidelity model of engine compressor performance defines nominal expected values of engine performance parameters, such as compressor efficiency and air flow, as a function of current operating conditions. A tracking filter component (308) compares the modeled performance parameters with actual calculated performance parameters obtained from sensor data, and maintains a separate actual model of engine performance that modifies the nominal performance parameter values to match the calculated parameter values using parameter modifiers. A health index is derived (1112) as a function of the parameter modifiers, and a water-wash notification is generated (1118) when the health index is indicative of a significant loss of fuel efficiency due to dirt accumulation in the engine's compressor.

摘要： A method 300 for operating a gas turbine engine having a starter-electric generator (108) driven by one of a plurality of shafts of the gas turbine engine is provided. The method includes determining 302 a desired amount of thrust to be produced by the gas turbine engine, as well as a desired amount of electrical power 304 to be drawn from the starter-electric generator (108) of the gas turbine engine. The method operates the gas turbine engine to produce 306 the desired amount of thrust, while drawing 308 less than the desired amount of electrical power from the starter-electric generator (108). Drawing less than the desired amount of electrical power from the starter-electric generator (108) allows for the desired amount of thrust production, allows for the desired amount of thrust production more quickly, or allows for maintenance of a stall margin for any purpose (such as to increase an efficiency of the engine or to allow for certain engine designs).
