摘要

提出了一种带有中间喷管的新型双脉冲固体火箭发动机技术方案

设计了一台结构参数可调的试验发动机;改变发动机的结构参数进行多次点火试验

获得了试验数据;对该发动机的多喉道流动过程建立了二维非稳态流动模型

对试验方案进行了大量计算

并与试验数据进行了比较分析。

Abstract

A new type of dual-pulse solid rocket motor concept with an intermediate nozzle is presented and a test motor with changeable structural parameters was designed.Several firings of the motor with changing the structural parameters were conducted and the corresponding experimental data were obtained.A two-dimensional unsteady mathematical model was constructed for analyzing the multithroat flowfields

and numerical calculation with this model was completed.The results were compared with the test data.
