Abstract

To solve the problem of excessive shock wave intensity in the channel of the launch box during the shock wave opening process, a baffle is installed at the rear end of the launch box to reduce the shock wave intensity. The effects of the baffle on the evolution of shock wave and gas flow field are investigated using computational fluid dynamics methods. Results show that the baffle effectively limits the propagation path of the shock wave and high-pressure gas, significantly reducing both the intensity and speed of the shock wave. Additionally, the baffle, as a reflective surface, increases the intensity of reflected shock wave at the rear end of the launch box. Further, a smaller baffle hole diameter leads to a weaker shock wave intensity within the launch box. By adjusting the baffle hole diameter, the shock wave intensity can be effectively controlled, ensuring that the launch box pressure meets launch requirements.
