Abstract: An assembly for an aircraft propulsion system including a nacelle extending around a longitudinal axis and including an internal face that delimits, with an external face of the aircraft propulsion system, a fire zone, an extinguisher for extinguishing a fire in the fire zone, the extinguisher including a tank for containing an extinguishing agent, and a spraying nozzle for spraying the extinguishing agent out of the tank and into the fire zone, an activation device for activating the extinguisher, and a controller that transmits a control order to the activation device, the activation device receiving the control order and transmitting an activation order to the extinguisher, the activation order activating the extinguisher so as to cause the expulsion of the extinguishing agent via the nozzle. The extinguisher is mounted on the nacelle. The assembly includes one or more of a wireless communicator and a cable.

Abstract: A thrust reverser for a propulsion unit, incudes movable grids, two half-assemblies forming part of a secondary stream and, at the six o'clock position, a connecting beam intended to be mounted in cantilever with a fan housing. The half-assemblies are hinged at the twelve o'clock position so as to enable their “butterfly” movement between a flight configuration and a maintenance configuration. The connecting beam includes a connecting member configured to cooperate, in the form of a tenon and groove connection, with the half-assemblies when these are in flight configuration. The reverser also includes, downstreamof the connecting member, locks capable of locking the half-assemblies in flight configuration.

Abstract: An assembly for an aircraft gas turbine engine includes a nacelle extending substantially around a longitudinal axis and including a fixed structure disposed around the aircraft gas turbine engine, the fixed structure including an internal surface suitable for delimiting with an external surface of the gas turbine engine a fire zone of the nacelle, a thermal protection covering the internal surface of the fixed structure of the nacelle at the level of the fire zone of the nacelle, and an extinguisher designed to extinguish a fire in the fire zone of the nacelle, the extinguisher including a tank suitable for containing an extinguishing agent. The tank is located between the thermal protection and the internal surface of the fixed structure of the nacelle.

Abstract: A propulsion assembly including an actuator connected to an outer casing of a turbomachine by a connecting structure. The connecting structure is fastened in line with a structural arm connecting the outer casing to a hub of the turbomachine, with a common fastening device, with the result that the arm can withstand loading forces of the actuator while relieving the outer casing.

Abstract: A propulsion assembly for an aircraft equipped with a thrust reverser comprising an actuator for moving a movable structure between an advanced direct thrust position and a retracted thrust reversal position, the propulsion assembly further comprising an actuator support device equipped with a first connecting part for connecting it to the deflection edge and/or to the outer shell of the intermediate casing, with a second connecting part for connecting it to a body of the actuator, and with a central part running axially between the shell and the actuator. Moreover, the actuator support device forms a guide for a set of cascades of the movable structure.
