Abstract:
The actual bunling rate of propellant is difficult to measure because 0f the high temperature and pressure of rocket motor．In order to research the dependency of the buming rate on working conditions，identification of the experiments results of rocket motor underwater by means of least square method was conducted．Three kinds of expI．essions were introduced and each of them was adopted to the identi6cation process．The optimum identification solution of the steady buming rate model parameter was obtained．The results show that the residual enlor of the exponent format is the smallest，thus the exponent format is the most reasonable format for describing the buming rate of the new propeUant．
