Abstract

An aircraft propulsion system (22) includes a gas turbine engine (24), a power transfer assembly (26; 126), and a controller (78). The gas turbine engine (24) includes a first spool (40) and a second spool (42). The power transfer assembly (26; 126) includes a first motor-generator (80; 128), a second motor-generator (82; 130), and a motor control assembly (76; 132). The first motor-generator (80; 128) is operably coupled with the first spool (40). The second motor-generator (82; 130) is operably coupled with the second spool (42). The motor control assembly (76; 132) is electrically connected to the first motor-generator (80; 128) and the second motor-generator (82; 130). The motor control assembly (76; 132) is configured to control an operating voltage of the power transfer assembly (26; 126). The controller (78) is connected in signal communication with the motor control assembly (76; 132). The controller (78) is configured to identify a target operating voltage of the power transfer assembly (26; 126) selected in response to an aircraft altitude input to the controller (78) and control the motor control assembly (76; 132) to control the operating voltage at the target operating voltage.
