High temperature electro-magnetic actuators (HTEMA)

ABSTRACT: RCT proposes a design and validation effort resulting in a high temperature, high reliability class of all electromagnetic actuator designs with minimal/no heat load on aircraft cooling systems. Size and weight are consistent with aircraft engine limits and are applicable to manned and unmanned vehicles. Actuator designs are consistent with military specifications and are anticipated to replace JSF engine nozzle actuation hydraulic actuators. Actuator performance requirements identified with the Air Force and RCT partner(s) will provide a basis for design and optimization trades, followed by a point design selections and detail design efforts consistent with aircraft engine applications. At the end of Phase I, design validation by analysis enables a Phase II proposal for laboratory hardware demonstrations, risk reduction and commercialization roadmap. Hardware interface will be consistent for integration into engine test stands for Phase III testing/transition. Key technical aspect includes actuator power, weight, size, efficiency, speed, stroke, force/torque, , thermal and mechanical robustness (margin), reliability, life cycle cost, failure modes and effects, and maintenance needs. BENEFIT: Commercial opportunities include more reliable electromagnetic actuators which can be used in down hole drills, high temperature industrial actuators, nuclear fission and fusion reactor actuators and geothermal power conversion systems.
