Abstract
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.
Claims20
A vehicle comprising a jet propulsion engine, a vehicle hydraulic circuit and at least one thrust reverser actuation system, the at least one 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 of the actuators comprising:
- a cylinder;
- an actuator hydraulic circuit;
- and
- a bi-directional electrically-driven pump configured to pump hydraulic fluid through the actuator hydraulic circuit,
- wherein, for each of the actuators, the actuator hydraulic circuit and the pump are configured such that the direction of the pump dictates the direction of the actuation of the actuator;
- wherein each of the actuators comprises a lock for locking the actuator in position, wherein said lock comprises a locking member configured to extend into the cylinder and is connected to the actuator hydraulic circuit and is arranged to be unlocked by the hydraulic fluid of the actuator hydraulic circuit when the pump pressurises the fluid.
