Abstract: A device for starting a gas turbine in an aircraft includes an electrical power supply delivering a direct current and a drive electric motor connected to the power supply, independent of the turbine to be started and having an output shaft mechanically coupled to an input shaft of the turbine to rotate with it. The drive electric motor is a three-phase alternating current synchronous motor and is controlled by an inverter connected to the power supply. Applications include situations in which the turbine to be driven is a high-power turbine.
