一、前言利用已有的理论、经验和半经验公式,对初步设计的发动机进行性能予示,即对压力—时间曲线,推力—时间曲线和比冲,总冲等数据进行予算是非常需要的。资料在过去研究的础基上,进一步发展了予示方法和计算机程序,并得出予示的比冲在±2%,推力和总冲在±5%精度范围内的结果。本文基于介绍的基本方法并参考有关资料,叙述对固体发动机适用的性能予示方法。
I. Preface It is very necessary to make preliminary performance on the engine by using the existing theory, experience and semi-empirical formula, that is to say, the pressure-time curve, thrust-time curve, specific impulse and total impulse are needed . Data Based on the previous research, we further developed the presented methods and computer programs and obtained the results that the specific impulse of ± 2%, thrust and total impulse were within ± 5% accuracy. This article based on the introduction of basic methods and with reference to the relevant information, describes the performance of the solid engine to show the method.
