Two servovalve thrust reverser actuator system

A fluid control system configured to operate a first hydraulic actuator coupled to a thrust-reversing element coupled to a nacelle of an engine assembly and a second hydraulic actuator coupled to the thrust-reversing element, the fluid control system comprising:

• an electrohydraulic servo valve operable to selectively route fluid between a pressurized fluid source, the second hydraulic actuator, and a fluid return reservoir;
• a directional control valve operable to selectively route fluid between the pressurized fluid source, the first hydraulic actuator, the second hydraulic actuator, the electrohydraulic servo valve, and the fluid return reservoir;
• and
• a controller configured to operate the electrohydraulic servo valve, wherein the first hydraulic actuator, the second hydraulic actuator, the directional control valve, and the electrohydraulic servo valve are fluidically connected to the pressurized fluid source and the fluid return reservoir.

A method of operating an engine thrust reverser comprising a thrust-reversing element movable between a stowed position and a deployed position, the method comprising:

• transitioning the thrust-reversing element from the stowed position to the deployed position by:
• comprising selectively routing, by a directional control valve, fluid between a pressurized fluid source, a first hydraulic actuator, a second hydraulic actuator, an electrohydraulic servo valve, and a fluid return reservoir;
• conveying fluid from the directional control valve to the first hydraulic actuator coupled to the thrust-reversing element;
• conveying fluid from the directional control valve to the second hydraulic actuator coupled to the thrust-reversing element;
• conveying fluid from the directional control valve to the electrohydraulic servo valve, wherein the electrohydraulic servo valve is operable to selectively route fluid between the directional control valve and the second hydraulic actuator;
• and
• controlling, by a controller, operation of the electrohydraulic servo valve.
