摘要
本文考虑了火箭的级间连接裙,建立了火箭发动机壳体封头形状优化的一般方程。问题归结为求积分泛函的极小值。用数值解法求得了椭球封头和Cassinian封头的优化解。
The general equations of the configuration optimization of the rocket motor closure with the skirt which is used to the interstage junction is derived. This problem is reduced to determine a minimum of the integral functional. The optimal solution of the ellipsoidal closure and Cassinian closure is obtained by the numerical method.
