功率电传机载作动系统方案分析

Scheme Analysis of Power by wire Airborne Actuation Systems

综述了目前正在验证中的各种功率电传机载作动系统的发展状况，并详尽描述其工作原理，在分析其各自的优缺点之后，针对当今技术发展现状以及新型作战飞机对作动系统的要求，提出了两种新型的功率电传作动系统———电机泵复合控制功率电传作动系统和电机泵阀复合控制功率电传作动系统，初步实验分析证明了该两种方案作为向全电作动系统的过渡是可行的，将对未来机载作动系统的研制具有实际指导意义．

An overview is given of various power by wire(PBW) airborne actuation systems currently demonstrated, along with descriptions of their mechanism of operation. After discussing advantages and disadvantages of existing PBW actuation systems, two kinds of new PBW actuation systems, the electromotor pump compound control and the electromotor pump valve compound control, are proposed. The experiments of scheme demonstration present that two kinds of PBW actuation systems proposed are feasible and are necessary transitional forms toward all electric actuation systems. Further improving the performance of each component in the systems will increase the performance of the whole systems.
