| Abstract: | An engineering method of the accuracy prediction of the total impulse for Solid RocketMotor (SRM) is presented in this paper. Using the compufer software, the relative deviation of thetotal impulse can be controled by adjusting the tolerance zone of those parameters having influence onthe total impulse accuracy. And it can reach the technical specification. Some examples show that themethod is available. This paper also analyses suitable actions to obtain good accuracy of the totalimpulse. The tolerances and technical conditions of major performance parameters and structuraldimensions for SRM can be made in reason based on the total impulse accuracy prediction. |
