Abstract
The invention relates to a turbine engine () with a semi-fixed turbine, particularly for aircraft driving a receiver () controlled so as to preserve a roughly constant rotation speed. The turbine engine, in particular via a gear system (), drives the receiver and an LP compressor () with an LP turbine (). According to the invention, the gear system has a torque control system () maintaining a constant ratio between the drive torque of the receiver transmitted by the gear system and the drive torque of the LP compressor transmitted by this same gear system.
