Actuation Solutions Actuation Solutions
Curtiss-Wright’s actuation technology stems from over 60 years of proven aerospace motion control design and production experience. Utilizing proven linear and rotary electromechanical designs, we employ a modified commercial-off-the-shelf approach to increase speed to market, reduce program risk and ensure all requirements are met. And when it comes to adopting electric actuation, our products reduce maintenance costs and provide more reliability and efficiency than hydraulics.
When a custom solution is required, our engineering expertise includes system modeling as well as integration testing and validation. Curtiss-Wright’s vertically integrated approach comprises development of controllers, motors, brakes, sensors and other accessories in-house, which results in a highly optimized solution. No matter the space, power, or weight challenge, Curtiss-Wright’s actuation solutions are the trusted choice.
