Mechanical Input Actuator

产品概况：

Parker Aerospace mechanical input actuators have been the industry’s leading flight control actuators for over 40 years. Parker’s mechanical input actuators control primary and secondary flight controls for a safe and reliable means of translating mechanical input signals from the pilot into hydraulically powered output motion. The pilot input provides a mechanical input command to the hydraulic servo and mechanical linkage provides feedback to move the flight control surface to the desired position.

The mechanical input positions the hydraulic control valve, which directs hydraulic pressure and flow to extend or retract the piston, thereby moving the aircraft flight control surface to the desired position. Our mechanical designs offer overload protection, fail safe features, ballistic tolerant capabilities, and optimized packaging to reduce weight and are known throughout the industry for providing reliable performance within customer specifications.

Our pedigree of mechanical input actuators are commonly referred to as power control actuators, servo cylinders, servo actuators, and hydraulic actuators for a variety of airplane and helicopter programs.
Parker’s control actuation technology for primary and secondary flight control actuation has been tested, proven, and trusted in commercial and military applications for decades. We provide precise position-control actuation solutions that are optimized for high-reliability and fault-tolerant performance.

Parker’s engineering team reflects top industry talent who are focused on customer success. Contact one of our business development managers to see if our products will meet your flight control needs.
