PROPULSION ASSEMBLY COMPRISING AT LEAST ONE REGULATED VENTILATION DEVICE, AIRCRAFT COMPRISING AT LEAST ONE SUCH PROPULSION ASSEMBLY

Aircraft propulsion unit equipped with at least one ventilation device (52) configured to cool at least one zone of the propulsion unit. This ventilation device is regulated and comprises at least one ventilation hole (54) which opens into the zone to be cooled, at least one valve (56) movable between a closed position in which the valve (56) closes off the ventilation hole (54) and an open position in which the valve (56) at least partially clears the ventilation hole (54), at least one thermoelectric generator (64) configured to generate an electrical current as well as at least one servo control configured to control the position of the valve (56) using the electrical current generated by the thermoelectric generator (64). This solution makes it possible to adjust the air flow rate drawn in according to cooling requirements.
