Patent ID: 8286916

Claim:
An aircraft comprising: a wall having an exterior surface in contact with air flows external to the aircraft; an internal cavity in the aircraft recessed relative to the exterior surface of the wall; at least one mobile trapdoor which in a closed position prolongs the exterior surface in such a way as to shut off the cavity from the exterior, and which in an open position projects relative to the exterior surface in such a way as to open the cavity to the exterior; a transducer positioned on the exterior surface of the wall; and at least one mobile aerodynamic deflector whose movement is slaved to that of the at least one trapdoor, the at least one mobile aerodynamic deflector deflecting airflow from the at least one mobile trapdoor when the at least one mobile trapdoor is in the open position such that the airflow from the at least one mobile trapdoor is deflected away from the transducer.
