模拟发动机与全尺寸发动机相关性研究

Research on the correlativity between model motor and full size motor

摘要:

以某导弹固体火箭发动机及其缩比的模拟发动机为研究对象,讨论了二者零维内弹道的相关性以及点火启动增压过程中和长期贮存环境温度变化过程中其内部力学响应的相关性。

Abstract:

In this paper, some solid rocket motor used by missile and its model motor are treated as the objects of study. The correlativity between them on the internal ballistic and on the response of mechanics during the pressure’s increasing in igniting process or during the long-term storage with temperature’s changing is discussed.
