Abstract:
1. An aircraft nacelle in which a power plant with an outside surface is arranged, the aircraft nacelle comprising: an inside wall that, with the outside surface of the power plant, delimits a bypass duct; at least one moving part so as to create at least one lateral opening; and a thrust reversal device comprising at least one moving physical obstacle that can occupy a first retracted state in which said obstacle does not deflect the stream that circulates in the bypass duct and another deployed state in which said obstacle at least partially deflects the stream that circulates in the bypass duct toward said at least one lateral opening; wherein a ring is arranged in the bypass duct, radially spaced from the inside wall of the nacelle and the outside surface of the power plant, said ring comprising: on a first side, a series of outside flaps that can occupy a first retracted state in which the outside flaps do not project relative to the ring and a second deployed state in which the outside flaps do project relative to the ring in the direction of the inside wall of the nacelle so as to at least partially deflect the stream that circulates between the ring and the inside wall of the nacelle in the direction of said at least one lateral opening, and on a second side, a series of inside flaps that can occupy a first retracted state, in which the inside flaps do not project relative to the ring and a second deployed state in which the inside flaps do project relative to the ring in the direction of the outside surface of the power plant so as to at least partially deflect the stream that circulates between the ring and the outside surface of the power plant in the direction of said at least one lateral opening.
