High-Temperature Actuators for Aircraft Propulsion Systems

摘要

Future "more electric aircraft" (MEA) will require electric actuation systems for control surfaces and engine controls. Electric motors, drive electronics, and mechanisms are essential elements of aircraft actuation in MEAs that incorporate Electro-Magnetic Actuators (EMAs). High-temperature environments experienced in aircraft applications place demands on actuator components, materials, and insulation systems that dictate the use of new technologies and materials. High Temperature Electromagnetic Actuator (HTEMA) options for high-temperature aircraft environments include appropriate motor types, drive and control electronics, mechanisms, materials, and construction methods. These options are evaluated to identify candidates that meet the challenges of tomorrow's MEA actuators.
