Compact, High Torque, Hinge Actuator for Next-Generation Thin-Wing Aircraft Flight Control

ABSTRACT: The Air Force is seeking a compact, high torque, rotary EMA technology capable of controlling flight control surfaces directly at the hinge line in the next generation of thin-wing aircraft. Proposed for this application is an advanced EMA technology based on an axial flux, permanent-magnet machine structure. The unique shape of this device enables efficient integration into the wing structure and represents a promising solution for this application. BENEFIT: If successful, this project will result in a small, high-torque, hinge-actuator technology suitable for use in thin-wing military aircraft. Other aircraft could use this system as well. Compared to current hydraulic technology, this system should simplify installation, improve efficiency, reduce maintenance, and lower operational cost. It should also find service in many other non-aviation applications, such as industrial automation and robotics.
