A thrust reverser actuation system for a jet propulsion engine for a vehicle, the thrust reverser actuation system comprising: a plurality of hydraulically-driven thrust reverser actuators for actuating one or more thrust reverser components of the jet propulsion engine, each actuator comprising: a hydraulic circuit; and a bi-directional electrically-driven pump configured to pump hydraulic fluid through the hydraulic circuit, wherein the hydraulic circuit and the pump are configured such that the direction of the pump dictates the direction of the actuation of the actuator.

Thrust reverser actuation system

A locking mechanism comprises an S-shaped locking member which comprises respective locking hooks arranged at the end of opposed arms of the locking member. A pivot is arranged between the arms of the locking member. The locking member rotates around the axis (A) of the pivot. The locking mechanism further comprises a coupling for coupling the locking member to an actuator for rotating the locking member around the pivot axis (A). The coupling comprises at least one coupling element, an actuator coupling for coupling the at least one coupling element to the actuator and first and second drive couplings for coupling the at least one coupling element independently to each arm of the locking member for transmitting rotational movement thereto, such that failure of one arm of the locking member will not cause loss of drive to the other arm of the locking member.

Locking mechanism

A hydraulic thrust reverser system (TRAS) including a first return line having a first check valve therein, and a second return line having a second check valve therein, wherein the first return line and the second return line are in fluid communication with each other via a fluid restrictor located upstream of the first and second check valves, wherein the first return line extends from a piston system of the TRAS, the piston system being for moving at least one thrust reverser door, and wherein the second return line extends from a lock system of the TRAS, the lock system being for controlling locks to selectively prevent the movement of the at least one thrust reverser door.

Hydraulic thrust reverser actuation system

An actuator arrangement comprises an epicyclic gear setincluding a sun gear, at least one planet gearin meshing engagement with the sun gear, and a ring gearin meshing engagement with the planet gear, the planet gearbeing carried by a rotatable support, wherein one of the sun gearand the supportis arranged to be driven by a motorand the other of the sun gearand the supportis arranged to drive an actuator, and a clutch arrangementoperable to resist rotation of the ring gear
