Title Ballistic Performance of solid research within the traveling charge
Abstract
Systematic introduction to the domestic and foreign traveling charge is technically solid achievements.By way of comparison and mapping analysis of different traveling charge amount, the amount of the main charge, the impact of the ignition delay time for the entire process chamber pressure within the ballistic curve.The establishment of a solid traveling charge classical trajectory model and Preparation of the corresponding computer program are all ready .The use of numerical simulation and calculation procedures on the impact of ballistic performance parameters were analyzed .The corresponding computer program are compiled. Calculation program for numerical simulation and affect the ballistic performance parameters were analyzed.The p-t、p-t、v-t、p-l、v-l curve obtained by numerical simulation results and experimental preferably consistency.To verify the basic characteristics of the solid traveling charge each value GUN. The conclusion that the performance characteristics of the traveling charge is effective.
