Abstract
The aircraft motor architecture comprises two reversible electric machines (), the rotors () of which are linked both to the low pressure shaft () and to the high pressure shaft () by transmissions () alternately disengaged depending on the direction of rotation of the rotor (), the transmissions comprising passive one-way clutches (), the engagement directions of which are opposed. Independent modes of operation of the machines, as a starter or as an electric generator of each of the shafts, are thus provided.
