An aircraft nacelle includes a cowling, an engine housed in an internal volume of the cowling, and at least one thrust reverser, an air passage duct being formed between an internal wall of the cowling and an external wall of the engine. The cowling includes a fixed cowling part and a moving cowling part that is translationally movable between a plurality of positions, at least one of the positions varying an air flow through the duct. The moving cowling part includes the at least one thrust reverser so that translational movement of the moving cowling part also allows the moving cowling part to switch from a position in which the at least one thrust reverser is retracted into a reverse-thrust position in which a bypass flow is deflected to generate a reverse thrust.

Pivoting door for thrust reverser with stable intermediate position

An aircraft nacelle in which a power plant with an outside surface is arranged, whereby the nacelle has an inside wall that with the outside surface of the power plant delimits a secondary annular pipe, at least one moving part so as to create at least one lateral opening, and a thrust reversal device that has at least one moving physical obstacle that can occupy a first retracted state in which it does not deflect the stream that circulates in the secondary pipe and another deployed state in which it at least partially deflects the stream that circulates in the secondary annular pipe toward the at least one side opening, characterized in that it includes a ring that is arranged in the secondary pipe, distant from the inside wall of the nacelle and the outside surface of the power plant that supports the at least one moving physical obstacle.
