AIRCRAFT ENGINE NACELLE AIR INTAKE LIP PROVIDED WITH A DEVICE FOR PASSIVELY SEALING AN EXHAUST DEVICE

Air inlet lip (12) of an aircraft engine nacelle equipped with a passive closure device for a communication orifice The subject of the invention is an air inlet lip (12) of a nacelle (10) of an aircraft engine equipped with a passive closure device (22) of exhaust devices (20). The passive closure device (22) is capable of taking a closure position (P1) in which it closes the exhaust devices (20) and an opening position (P2) in which it releases the exhaust devices (20) as a function of the temperature experienced by the passive closure device (22). Thus, the exhaust devices (20) are closed in all flight phases where de-icing of the air inlet lip is not necessary.
