| Abstract: | Based on the transient throat erosion data from solid motor firing tests, a digital time scries analysis is introduced and a mathematical statistical model for the laws of throat erosion is developed. The process of throat erosion is computer-simulated by using the Mont Carlo simulation method. The results have shown that they are in good agreement with the actual results. |
