Abstract
The turbojet comprises a high pressure spool and a low pressure spool driving a fan. In order to produce electricity, it further includes an electricity generator arranged in the fan and taking power therefrom. The generator comprises a rotor incorporated in the fan and a stator incorporated in the fan casing. This disposition for the electricity generator avoids problems of engine operability at low speed and enables mechanical power to be converted into electrical power with high efficiency. In addition, installation and maintenance of the electricity generator are facilitated by the generator being implanted in the fan.
