Abstract

An aircraft propulsion system (20) and a method of controlling a compressor (23) operating line in a propulsion system (20) for an aircraft is provided. The system (20) includes a gas turbine engine (22), an electric motor (34; 36; 41), a gearbox (28), and a propulsor (26). The gas turbine engine (22) has a compressor (23), a combustor (25), a turbine (27), and an engine shaft (29) extending between the compressor (23) and the turbine (27). The gas turbine engine (22) is in drive engagement with the gearbox (28), and the propulsor (26) is driven by the gearbox (28). The method includes: controlling the gas turbine engine (22) to provide motive force to the propulsor (26); determining an operational line of the compressor (23); and controlling the operational line of the compressor (23) by controlling the electric motor (34; 36; 41) to change an amount of load on the compressor (23) attributable to the electric motor (34; 36; 41).
