| Abstract: | Based on the interior ballistic models of solid rocket motors.some independent random variables for interior ballistic calculation are selected and used for establishing the probability statistical models and determining the distribution of the variables.Then,the interior ballistic performances are simulated and computed by means of Monte -Carlo method.Anafysis of the average value pand the standard deviation a of performances and conparison with test results show that the computation method is feasible and the data are confident. |
