Abstract: A thrust reverser for an aircraft propulsion assembly, this reverser including a mobile annular external structure, a single actuator for controlling the position of this mobile external structure and a device for guiding the mobile external structure when changing its position. The actuator and the guiding device are housed in a fairing of a pylon of the propulsion assembly to a wing or fuselage of the aircraft.

Abstract: A thrust reverser for an aircraft propulsion assembly, this reverser including an outer structure movable between a closed position and an open position of two primary latches configured to lock the movable outer structure in the closed position. The movable outer structure includes an output end that is oblique with respect to the longitudinal central axis so as to orient the thrust laterally. In order to compensate the tilting moment of the movable outer structure, which results from this lateral orientation of the thrust, the primary latches are offset with respect to a median longitudinal plane passing through the longitudinal central axis of the reverser.

Abstract: A thrust reverser for an aircraft propulsion unit, of the type having a mobile cowl able to move between a closed position that allows the propulsion unit to generate thrust and an open position that allows the propulsion unit to generate a reverse-thrust for slowing the aircraft. The reverser includes braking elements such as a slot and a peg respectively integral with a fixed part of the reverser and with the mobile cowl. These braking elements are configured to cooperate with one another by sliding, with friction, when the mobile cowl effects an overtravel, beyond the open position, so as to generate a braking force that opposes this movement. In one preferred embodiment, the slot for this purpose includes a restriction in section along the direction of travel of the mobile cowl.

Abstract: A thrust reverser for an aircraft propulsion unit, this reverser including a fixed structure and a mobile external structure able to move between a closed position and an open position so as to cause the reverser to transition respectively between a direct-jet configuration and a reverse-jet configuration. The reverser includes, on the one hand, one or more actuators configured to move the mobile external structure between the closed position and the open position. The reverser includes, on the other hand, at least one initiator configured to apply to the mobile external structure a force that initiates a closure travel in which the mobile external structure is moved from the open position towards the closed position.
