ADVANCED COOLING FOR HIGH POWER ELECTRIC ACTUATORS

Abstract : The development of more electric technologies for future military aircraft promises to provide significant redundancy, reliability, maintainability, and performance benefits. Advanced Cooling For High Power Electric Actuators particularly address the use electro-mechanical actuators (EMAs), and an approach for cooling EMAs using the combined concepts of passive reflux cooling and phase change materials (PCMs) for energy storage. The planned program involves four Phases: Phase I Requirements and Trade Studies. Phase II Detailed Design. Phase III Fabrication and Test Plans. Phase IV Test/Data Correlation. During Phase I Sundstrand identified actuator cooling requirements and evaluated the effects of several critical parameters on the use of passive reflux cooling in combination with PCM.
