Beschreibung
Zusammenfassung:	Aircraft turboprop engine (110), comprising at least one low-pressure body (12) and one high-pressure body (14), the low-pressure body driving a thrust propeller by means of a gearbox (16), the turboprop engine further comprising means for supplying air to an air-conditioning circuit (36) of an aircraft cabin, said supply means comprising a load compressor (60), a rotor (61) of which is coupled to said low-pressure body by means of said gearbox, characterised in that said supply means further comprise means for controlling the rotation speed of the rotor (61) of said compressor (60), which means comprise an electric motor (70), and a mechanical differential (72) for coupling a first output shaft (74) of said electric motor to a second output shaft (76) of said gearbox and to said compressor rotor (61), such that the rotation speed (V3) of said rotor depends on the respective rotation speeds (V1, V2) of said first and second output shafts.
