Abstract:
1. An aircraft nacelle comprising: 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 comprises 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 air passage duct, the moving cowling part comprising 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, the at least one thrust reverser comprising a pivoting door, the pivoting door comprises at least two extreme stable positions, a retracted position in which the pivoting door is incorporated into the cowling, and a reverse-thrust position in which a surface of the pivoting door that forms a part of an outer surface of the cowling in the retracted position is positioned partially inside and outside the nacelle to divert the bypass flow and to generate reverse thrust, the moving cowling part then being in a fully displaced position, wherein when the moving cowling part is in the at least one position that varies the air flow through the air passage duct, the at least one thrust reverser which comprises the pivoting door has a stable intermediate position in which a portion of the pivoting door that is positioned downstream in relation to a direction of travel of the bypass flow through the nacelle is positioned outside of the nacelle.
