Status and development of electrically powered actuators for aerospace application

摘要

As the rapid growth of air traffic market in recent years, man-made CO2 emissions into the atmosphere increased largely. The economic and environment conflict need to be solved in aerospace industry. Currently, towards creating greener, safer and cheaper air transport, an interim and attractive solution is towards 'More Electric' using more electric power technological advancements for non-propulsive systems in aircraft and for thrust vector control in space. The power-by-wire actuators have gained more and more attentions in nowadays electrically powered actuation systems. The innovations and developments of electrically powered actuators, for recent aircraft even for next generation of more electric aircraft and for thrust vector control system of rocket applications are presented. For safety critical actuation system like flight control, landing gear, the safety and reliability issues are of particular importance, the common redundant configurations is presented.
