Title Simulation and analysis of interior ballistic process of guided ammunition
Abstract According to the characteristic of low load in the interior ballistic of guided ammunition ,including high chamber pressure and low velocity,based on the classical interior ballistic theory, A theoretical model and a mathematical model for the interior ballistic process of guided ammunition are established。By adopting the method of non dimensional mathematical model and the four order Runge Kutta method in time,Writing program to calculate the process of the interior ballistic of guided ammunition。According to the program, the internal ballistic calculation results of the guidance trajectory are obtained。What is more,he influence of the shape of the powder, the burning rate exponent and the burning rate coefficient on the interior ballistic trajectory is analyzed。In the same time,based on the analysis results, the optimization of the interior ballistic process of the guided ammunition was carried out。In the procedure of loading optimization,carrying on the optimization of mixed charge in the interior ballistic of guided ammunition。Finally,The optimization results and the results were compared and analyzed。
Keywords guided ammunition interior ballistic loading optimization mixed charge
