摘要： 用质心运动定理对双节套筒式延伸喷管的展开过程进行分析，得到一个二阶常微分方程；然后用四阶龙格－库塔法进行数值求解，可得到延伸出口锥的轴向位移、速度和加速度及展开时间，并以单节套筒式延伸喷管为例；计算结果与试验基本吻合．

Abstract: This paper analyses development process of a double nested extended nozzle by using the motion theory on center of mass,and a normal differential eguation of second-order is obtained.The axial displacement,velocity and acceleration of extended cones are obtained by solving the equation with Runge-Kutta's method of forth-order.This paper gives a sample of single nested extended nozzle.The computation results are fundamentally consistent with the results of test.The method in this paper can be used in the design of a nested extended nozzle.
