ROTARY HYDRAULIC MOTOR DRIVEN HYBRID THRUST REVERSER ACTUATION SYSTEM WITH END-OF-STROKE SNUBBING

摘要

An aircraft thrust reverser actuation system includes a plurality of actuator assemblies that are each configured, upon receipt of a drive torque, to move to a position. The rotary hydraulic motor is coupled to each of the actuator assemblies and is configured, upon receipt of hydraulic fluid, to rotate and supply the drive torque to each of the actuator assemblies. The control valve is in fluid communication with the rotary hydraulic motor and is configured, upon receipt of electrical current, to move to a valve position based on the magnitude of the received electrical current, to thereby control the direction and flow of hydraulic fluid to the hydraulic motor. The valve control is configured, upon receipt of thrust reverser commands, to supply the electrical current to the control valve and selectively vary the magnitude of the electrical current based on the positions of the actuator assemblies.

1. An aircraft thrust reverser actuation system, comprising:
a plurality of actuator assemblies, each actuator assembly coupled to receive a drive torque and configured, upon receipt of the drive torque, to move to a position; a rotary hydraulic motor coupled to each of the actuator assemblies and adapted to selectively receive hydraulic fluid at a fluid flow rate and differential pressure, the rotary hydraulic motor configured, upon receipt of the hydraulic fluid, to rotate and supply the drive torque to each of the actuator assemblies; a control valve in fluid communication with the rotary hydraulic motor and adapted to receive electrical current at a magnitude, the control valve configured, upon receipt of the electrical current, to move to a valve position based on the magnitude of the received electrical current, to thereby control the direction and flow of hydraulic fluid to the hydraulic motor; and a valve control coupled to selectively receive thrust reverser commands and configured, upon receipt of the thrust reverser commands, to supply the electrical current to the control valve and selectively vary the magnitude of the electrical current based on the positions of the actuator assemblies.
