| Abstract: | This paper builds one dimensional two phase flow mechanics models of the different stages in the interior ballistic of the non cased ammunition. According to the characteristics of combustion in the shooting process of the non cased ammunition and with the method of staged modeling employed, it investigates the rules of changes in the chamber and solves the equation numerically. And the principles of the circulation in the interior ballistics of the non cased ammunition are revealed. Finally the numerical results agree with the experimental curves quite well. |
