摘要:

本文提出对任何药型都通用的一维准定常内弹道计算方法和与其相适用的药柱计算方法.解决了药柱和一维准定常内弹道计算的配合问题.用本程序对某实际发动机的内弹道性能进行了计算,将计算结果和用零维燃烧模型计算结果及热试车结果进行了比较.

Abstract:

In this paper, a one-dimensi.onal quasi-steady internal ballistic calculation method universal to any grain and the corresponding grain calculation method are given and developed.The matching problem between.the grain calculation, is solved.A computer program is made and used to predict the internal ballistic performance of actual motor.The results of the numerical solution are also comp-ared with the results of zero-dimensional internal ballistic calculation as well, as experiment results.
