摘　　要：操纵面外挂点转动摩擦副结构是飞行器飞行姿态控制的关键部件。文章介绍了外挂点摩擦副结构的应用背景,通过试验方法模拟了外挂点转动摩擦副结构气动力、热载荷环境下的工作状态,分别在常温和700℃高温状态下获得了某C/SiC非金属高温转动摩擦副结构的动态摩擦系数,对比分析了温度等因素对动态摩擦性能的影响,为该类型结构设计提供了参考。The simplified calculation method of friction coefficient of the friction pair is described. For the effect of 700oC high temperature on the performance of friction pair, the research of frictional property of a kind of C/SiC friction pair was done by the help of experiment at normal and high temperature. And it did an analysis of effect of temperature on the friction coefficient. The study can be not only used to supply references on conformation design but also give advices to the improvement of experimental technology.
