| Abstract: | The calculation equations of the standard deviations for thrust,specific impulse,total impulse,flow rate and pressure of solid rocket motors are derived. According to the application requirements of solid rocket motors and based on the analysis of some important factors which affect these deviations, the equations are further simplified. The methods for predicting thrust performance deviation and evaluating reliability for solid rocket motors are given by using the error analysis theory and single factor test results. |
