摘要
Abstract
Tiltrotor which combines the advantages of helicopters and fixed wing aircraft,is a key direction for fu-ture aviation equipment development.The key component of tiltrotor-pylon conversion actuator is focused.In this paper,the tilting actuation principle of tiltrotor is introduced,the advantages and disadvantages of V-22 and BA609 pylon conversion actuator configurations are analyzed and compared.The key technologies of pylon conver-sion actuator of tiltrotor are analyzed,including power summing technology,double-layer telescopic ball screw technology,ball screw end shock damper technology.The power summing technology can realize double-system synthesis by speed summing or force summing,which is the key to improve the reliability of pylon conversion actua-tor.Double-layer telescopic ball screw can effectively shorten the volume after the actuator is retracted,reduce the space on the aircraft nacelle,and greatly improve the safety of the actuator.Shock damper is a means to effectively restrain the impact caused by the screw end collision,which is very suitable for linear output mechanism such as ball screw.关键词
