Actuation Solutions
We set the standard in hydraulic and electromechanical flight control actuation systems for military and commercial fixed-wing aircraft, rotorcraft and unmanned aerial vehicles. This includes complete design, development, qualification, and support for actuation that meets extremely rigorous requirements in aviation. We offer a full range of servo valves, power stages, manifolds, motors, gearing, position sensors, and electronics for optimal performance-to-weight ratio across applications.
Electromechanical Actuation
We are a technology leader for advanced cockpit-to-surface solutions for electromechanical actuation and flight control systems. We provide complete design, development, qualification and support to meet the most stringent requirements.
Fully integrated in-house design and manufacturing for all our motors, gearing, position sensors, actuation stages and electronics, allows us to ensure optimal performance-to-weight ratio across applications.
Hydraulic Actuation
We have been the industry-recognized expert in design, development and manufacture of hydraulic primary, secondary and utility flight control actuators for commercial and military aircraft and rotorcraft for more than 70 years.
For decades, we have pioneered actuation solutions, from hydromechanical versions on early Douglas and Boeing jet transports to multi-redundant Fly-by-wire (FBW) actuators for current military fighter aircraft.
Our flight control actuators power flight-critical control surfaces on the most advanced aircraft with high performance and high reliability in demanding operational environments.
Features & Benefits Highlights
- Triple-redundant on-board electronic controls
- Built in test (BIT), failure monitoring, and multiple digital bus options
- Greater than 5000 psi hydraulic power and control stages
- Advanced, light-weight materials
- Continued innovation on next-generation electro-hydrostatic actuators (EHA) that eliminate the need for a central aircraft hydraulic system for reduced weight and increased reliability
- Integrated solenoids, servo valves and position sensors
Precision Motors
Our motor expertise spans AC motors, brushless DC motors and stepper motors, as well as accessory devices such as brakes, clutches, tachometers, PMA alternators and eddy-current dampers.
Features & Benefits Highlights
- Motor product lines as frameless, standalone devices or fully assembled into actuation line-replaceable units
- Motors can also be supplied with our line of gearheads as a power drive unit or with a leadscrew output to deliver greater torque or force to the payload
- Most products can be wound for a broad range of supply voltages for use on equivalent DC links of less than 28 volts or greater than 800 volts.
Servo Valves
We lead the industry in design and manufacture of electro-hydraulic pressure and flow control servo valves for aerospace and defense. Nearly all fly-by-wire aerospace vehicles and engines rely on our solutions. Our servo valves are used worldwide on demanding fixed-wing aircraft, helicopters, space vehicles, missiles and engine applications.
