A method for controlling a motor assembly. This motor assembly includes at least a first electric machine and a gas turbine engine. The gas turbine engine includes a low-pressure shaft and a high-pressure shaft. The electric machine is coupled to the low-pressure shaft, and the control method includes a step in which a take-off of mechanical work is ordered from the first electric machine to brake a rotation of the low-pressure shaft in response to an activation of a thrust reverser of the gas turbine engine and/or a disturbance of the air flow in a transverse plane at an air intake of the gas turbine engine. A control unit suitable for carrying out this method, a motor assembly incorporating this control unit, the electric machine and the gas turbine engine, and a computer program to carry out this method.
A method for controlling an aircraft motor assembly comprising at least a first electric machine and a gas turbine engine with at least a high-pressure shaft and a low-pressure shaft mechanically coupled to the first electric machine, the control method comprising a step in which a take-off of mechanical work is ordered from the first electric machine to brake a rotation of the low-pressure shaft in response to an activation of a thrust reverser of the gas turbine engine.
