摘要

在固体燃料冲压发动机性能分析基础上

推导了某发动机的推力和比冲与入口流量和温度之间的关系式。然后通过数值模拟得出: 入口流量对推力和比冲影响大

而对入口温度的影响则较小

并定性讨论了产生这些影响的原因。同时

理论分析和数值模拟所得结果比较吻合。本文的研究对于了解固冲的特性和导弹总体设计都有一定意义。

Abstract

The relations of thrust and specific impulse to inlet air flow and temperature are derived from theoretical analysis of solid fuel ramjet (SFRJ) performance.Then numerical simulation of the SFRJ performance is completed with these relations and the results show that the thrust increases with the inlet air flow and specific impulse also increases

but the rate of increasing slows down as the flow increases.When inlet air temperature rises

the thrust increases but the specific impulse decreases.However

the influence of the inlet air flow is greater than that of the air temperature and reasons for both of the influences are also discussed qualitatively.
