摘要
分析计算了作动筒内摩擦力、延伸出口锥端面密封摩擦力、大气压力及喷管中燃气压力对双节套筒式延伸喷管展开特性的影响，其分析计算方法对双节套筒式延伸喷管设计及展开时间预估有指导作用。
This paper analyses deployment chsracteristics of a double nested extended nozzle under the influence of friction of a actuator, sealing friction of extended cone, atmospheric pressure and pressure of combustible gas. The methods presented in this paper have a guide action on design of the extended nozzle and estimation of the deployment time.
