计算机扫描法确定固体火箭发动机燃烧时间

To Determine Combustion Time of the Solid Rocket Motor by Means of Computer Scanning

研究了一种计算机扫描法确定发动机燃烧时间的方法，它适用于有明显拐点的发动机压强时间曲线数据处理，使数据处理程序化、自动化。与人工切线法相比较，计算机扫描法简便、快捷，且误差减小，适合于工程应用。

A Computer scanning method of treating the pressure time curves with apparent inflection point for solid rocket motor test to determine the combustion time on the basis of summarizing data treatment experience is presented.The method makes the data treatment automated and programmed and can be used to substitute the mannual tangent line method.By comparison with the mannual tangent line method,the computer scanning method is more simple,direct and accurate,so it is available for engineering use.
