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

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.
