Abstract
A thrust reverser including doors, a rear shell ring and an actuation system for synchronising the pivoting of the doors and the translation of the rear shell ring.
Claims10
A thrust reverser for an aircraft propulsion unit, comprising a fixed structure, a door, a ring forming a trailing edge and intended to be traversed by a fluid flow when the reverser is in a direct thrust configuration, an actuation system configured to simultaneously pivot the door between a closed direct thrust position and an open reverse thrust position and translate the ring between a forward position and a retracted position in relation to the fixed structure, and a guiding device for guiding the ring between the forward and retracted positions, the actuation system comprising:
- an actuator provided with a movable drive element,
- a first tie rod having a first end connected to the movable element of the actuator and a second end connected to the door,
- a second tie rod having a first end connected to the movable element of the actuator and a second end connected to the ring,
- wherein an entirety of the ring has an annular shape,
- wherein the second end of the second tie rod is directly connected to the annular ring, and
- wherein in the forward position, an entirety of the annular ring is positioned downstream from the first tie rod with respect to a direction of the fluid flow.
