【Abstract】 The mathematical recovery method of instantaneous thrust for SRMs is given on the basis of the mathematical compensation method, and the dynamic mathematical model of force measuring system is established. Input recovery test by means of a small structure system in laboratory was conducted to check the mathematical recovery method. This method has been used to analyze thrust curve of solid rocket motor firing test. It is shown that the recovered results are effective and reliable.更多还原
