Abstract
A method for controlling a motor assembly. The motor assembly includes a gas turbine engine and at least one electric machine which is mechanically coupled to a rotating shaft of the gas turbine engine so as to be rotated for generating electricity. In this control method, a mechanical power take-off setpoint by the electric machine is changed when an operating parameter of the gas turbine engine reaches a predetermined limit. A control unit adapted to perform this method, a motor assembly incorporating this control unit, the electric machine and the gas turbine engine, and a computer program for performing this method.
Claims12
A control unit of an aircraft motor assembly, said motor assembly comprising a gas turbine engine and at least one electric machine which is mechanically coupled to a rotating shaft of the gas turbine engine so as to be rotated for generating electricity, the control unit configured to control an increase in a setpoint for mechanical power take-off by the electric machine when an operating parameter, which is a flow rate of fuel supplied to a combustion chamber of the gas turbine engine, divided by a static pressure at an inlet of the combustion chamber of the gas turbine engine, drops to a predetermined minimum limit.
