Abstract
A device for cooling an aircraft propulsion system, including at least one cooling circuit with at least one air inlet equipped with an intake flap mobile between closed and open positions and at least one air outlet equipped with an exhaust flap mobile between closed and open positions, and at least one actuator coupled by at least one kinematic system to the pair of intake and exhaust flaps in such a manner that the intake and exhaust flaps are driven in synchronized movements and simultaneously occupy the closed position or the open position. This solution enables reduction of the number of actuators and, finally, the all-up weight of the aircraft.
