Abstract
A twin-spool turbine engine includes a low-pressure rotor and a high-pressure rotor, an alternator, including an inductor winding and an armature, the high-pressure rotor rotating the inductor winding of the alternator. The armature is mounted so as to rotate and the low-pressure rotor is connected to a clutch arranged so that the low-pressure rotor drives the armature in a manner that is contrarotational to the inductor winding when the clutch are engaged.
