【Abstract】 A simulation and calculation modeling of propellant combustion on launch of gas generator was built for the optimization problems of propellant combustion law on launch of a new missile,to predict the emission process of propellant combustion performance and parameters.In order to correctly simulate missile launching process and to accurately calculate the trajectory of the missile,we established the appropriate mathematical model and carried out a numerical solution.Based on the interior ballistic theory of knowledge,this paper established mathematicals model under the certain conditions,by using the Visual Studio platform for programming and using Runge Kutta method to solve the model to achieve a numerical simulation.Finally,the results of computer simulation data graph were given.The simulation results are basically in accordance with the experimental data.Applying in practical application,it can significantly reduce the cost of experiments and can be reused.更多还原
