Interior Ballistic Simulation and Optimization of Solid Pulse Thruster
摘要
Abstract
To study the internal ballistic characteristics of solid pulse thruster for improving the performance,the internal ballistic model considering ignition process was established according to working characteristics of different stages. The F-t curves were calculated respectively while the solid propellant grains were 13 ,16 ,19 . The effect of different igniter grain mass on the internal ballistic characteristics was analyzed. The simulation and test results have good agreement. The modeling and simulation of the solid pulse thruster and the thrust performance can be well described. The ignition charge can result in the greater initial peakpressure,and the influence of ignition charge on the internal ballistic performance must be considered in the phase of ignition. The optimization model of the nozzle structure of the pulse thruster was established based on the internal ballistic model, and the nozzle structure was optimized by using multi-island genetic algorithm. The result shows that the performance of the solid pulse thruster can be im-proved by reasonably designing the nozzle.关键词
