Thrust reverser hydraulic actuation system with servo synchronization

A thrust reverser system comprising:

• a first thrust reverser door configured to be actuated between an open position and a closed position relative to a nacelle of an aircraft;
• a second thrust reverser door configured to be actuated between an open position and a closed position relative to a nacelle of an aircraft;
• at least two hydraulic actuators attached to each of the thrust reverser doors and configured to actuate the thrust reverser doors between the open position and the closed position;
• a plurality of servo valves, wherein each of the servo valves is communicatively coupled with one of the hydraulic actuators and configured to control hydraulic flow to and from the hydraulic actuators;
• at least two position sensors mounted on each of the thrust reverser doors and configured to provide signals associated with a position thereof;
• and
• a control system configured to receive the signals from the position sensors and send command signals to the servo valves depending on an amount of offset between the signals received from the position sensors.

A method of actuating thrust reverser doors of a thrust reverser system, the method comprising:

• receiving a command with a control system to reverse thrust of at least one of the thrust reverser doors;
• sending a deploy command with the control system to at least two servo valves, wherein, when receiving the deploy command, the at least two servo valves are each configured to provide hydraulic fluid to one of a plurality of hydraulic actuators attached to at least one of the thrust reverser doors, thereby deploying the at least one of the thrust reverser doors toward an open or reverse thrust position;
• receiving signals containing position information with the control system from at least two position sensors mounted on at least one of the thrust reverser doors;
• and
• sending command signals with the control system to at least one of the servo valves to adjust at least one of hydraulic flow rate, hydraulic pressure, direction, and position of at least one of the hydraulic actuators depending on an amount of offset between the signals received from the position sensors.
