THRUST REVERSER HYDRAULIC ACTUATION SYSTEM WITH SERVO SYNCHRONIZATION

摘要

A thrust reverser system and method for controlling actuation thereof. The thrust reverser system may have a control system, two thrust reverser doors actuatable between an open position and a closed position, hydraulic actuators attached to and used to actuate each of the thrust reverser doors, servo valves each communicatively coupled with one of the hydraulic actuators to control hydraulic flow to and from the hydraulic actuators, and position sensors mounted on each of the thrust reverser doors to provide signals associated with a position thereof to the control system. The control system may send command signals to the servo valves to independently adjust at least one of hydraulic flow rate, hydraulic pressure, direction, and position of the hydraulic actuators depending on an amount of offset between the signals received from the position sensors.

1. A thrust reverser system comprising:
a thrust reverser door configured to be actuated between an open position and a closed position relative to a nacelle of an aircraft; a hydraulic actuator attached to the thrust reverser door and configured to actuate the thrust reverser door between the open position and the closed position; a servo valve communicatively coupled with the hydraulic actuator and configured to control hydraulic flow to and from the hydraulic actuator; a position sensor configured to provide signals associated with a position of the thrust reverser door; and a control system configured to receive the signals from the position sensor and send command signals to the servo valve depending on the signals received from the position sensor.
