Title  heavy caliber high-low Pressure gun’s assembling Powder and the structure designing of ignition and flame and the research of the numerical simulation method Abstract    Now, with the development of modern  advanced weapons, high-  low  pressure  principle  has the trend to be more and more widely used due  to its unique advantages in the field of weapons particularly  in the launch system of the low speed guns. Based on  consulting lots of documents about high and low pressure guns both abroad and at home, point at the launch characteristic of high-low pressure gun , adopted the method of the  numerical simulation  to research its interior  ballistic simulation  processes.  Established  the  launching  system of  the mathematics model and  the  physical model  of the  high  and  low gun. Using VB to write the interior ballistic procedure, the classical Rung-Kutta to solute the equation.  Achieved the  numerical simulation  for  the high-low pressure gun. And test for the pressure of gas and the regularity of the  pellets’ motion  in the high-and-low room. Get the  pressure-time traces,  projectile velocity-time trace, and travel-time trace.  Test results show that the establishment of the high-low  launch system  is reasonable and reliable. Finally,  point at  the filling  parameters  and structure parameters  to  analysis  the  internal ballistic  performances.  Provide the reference for the structure and the filling parameter of the high-and-low pressure gun. 
 Key words:  high-low  pressure gun,  interior  ballistic  design,  Rung-Kutta, numerical simulation
