According to the structure characteristics of high - low pressure chamber launcher, the interior ballistics of launcher is discussed by using the numerical simulation and experimentation. The mathematic model of launcher interior ballistics is provided, and the numerical simulation result is obtained. An experiment on chamber press and initial velocity of high-low pressure chamber launcher is carried, which demonstrates that the model is reasonable and reliable.
