Abstract
A twin-spool gas turbine turbojet comprising a high-pressure rotor; a low-pressure rotor; a low-pressure rotor shaft connected to a fan housed in a fan casing; and a fixed cowl element centered on the axis of the engine, upstream of the fan, on which there is mounted an electric current generator designed to take mechanical power off the low-pressure rotor shaft and convert it into electrical power.

A twin-spool gas turbine turbojet comprising:
- a high-pressure rotor;
- a low-pressure rotor;
- a low-pressure rotor shaft connected to a fan housed in a fan casing at an upstream end of the low-pressure rotor shaft, in reference to a direction of thrust;
- and
- a fixed cowl element centered on an axis of an engine upstream of the fan in the direction of the thrust and on which there is mounted an electric current generator designed to take mechanical power off the low-pressure rotor shaft and convert it into electrical power.

A method of mounting a current generator in the fan of a gas turbojet including a high-pressure rotor;
- a low-pressure rotor;
- a low-pressure rotor shaft connected to a fan housed in a fan casing at an upstream end of the low-pressure rotor shaft, in reference to a direction of thrust;
- and a fixed cowl element centered on an axis of an engine upstream of the fan in the direction of the thrust and on which there is mounted an electric current generator designed to take mechanical power off the low-pressure rotor shaft and convert it into electrical power, the method comprising:
- mounting the current generator on the fixed cowl element;
- positioning the fixed cowl element on the fan in such a way that the rotor element of the generator is in contact with the upstream end of the low-pressure rotor shaft;
- and
- immobilizing the cowl element on the fan casing with radial retaining arms.
