Abstract: A seal is interposed between two surfaces of an aircraft propulsion assembly. The seal includes at least two layers each comprising a plurality of strands made of a heat-resistant material, the strands of a first layer being oriented in a first orientation and the strands of a second layer being oriented in a second orientation different than the first orientation.

Abstract: 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.

Abstract: The invention relates to 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 (7) being formed between the internal wall of the said cowling and an external wall of the said engine (12). According to the invention, the said cowling comprises a fixed cowling part (2) and a moving cowling part (3) capable of translational movement between a plurality of positions, at least one of the said positions varying the air flow through the said duct (7), the said moving cowling part (3) comprising the said at least one thrust reverser so that translational movement of the said moving cowling (3) also allows the said moving cowling (3) to switch from a position in which the said at least one thrust reverser is retracted into a reverse-thrust position in which the bypass flow is deflected to generate a reverse thrust.
