METHOD AND AIRCRAFT HAVING AT LEAST ONE COMBUSTION ENGINE AND A DRIVE SYSTEM HAVING AT LEAST TWO ELECTRIC MACHINES

The present invention relates to an aircraft (1) provided with a power plant (10) provided with at least one combustion engine (20) mechanically connected to a drive system (30), the drive system (30) comprising two electrical machines (35, 40) each connected by a kinematic chain (50) to the combustion engine (20), the two electrical machines (35, 40) being electrically connected to at least one electrical energy source (60). The aircraft (1) comprises a manager (70) controlling at least one mechanical power or engine torque delivered by each of the two electrical machines (35, 40) according to a current operating mode, said manager (70) being configured during a higher operating mode to control the two electrical machines (35, 40) so that the two electrical machines (35, 40) deliver different and unaffected mechanical powers or engine torques.
