21世纪航空发动机动力传输系统的展望

Prospects of Aeroengine Power Transmission System in the 21st Century

21世纪航空发动机动力传输系统仍以机械传动为主 ,在主轴轴承、润滑、齿轮传动及主轴密封方面 ,将继续对付与迎接先进发动机更高使用要求的挑战。电磁轴承与电气化附件传动研究方兴未艾 ,在航空发动机上应用已为期不远了。

In the early time of the 21st century the power transmission system of aeroengine still will be based on mechanical transmission,and will face the challenges of advanced aeroengine in respect to mainshaft bearing,lubricating,gear transmission and sealing.The researches on the electro magnetic bearings and the electro driving accessories,which will be used on future aeroengines,are just unfolded.This paper also introduces the development work and targets of the key laboratory of aeroengine power transmission in brief.
