According to the structural characteristics of small-bore high-low-pressure chamber launch system, the internal ballistic characteristics of the small-bore high-low pressure chamber launch system are studied by means of numerical simulation and experiment. The interior ballistic mathematical model of high and low pressure chamber launch system was established by classical interior ballistic theory and the numerical simulation and experimental verification were carried out. The results show that the numerical simulation results are close to the experimental ones, which proves that the established internal ballistic model is reasonable and reliable.
