    Abstract
  • In this study, for the muzzle brake with a side hole angle of 120° and the hole diameter of 16 mm used in a first-stage gas gun with a diameter of 50 mm, the flow field morphology is simulated, based on 3D unsteady Navier-Stokes equations and multi-region dynamic grid technology. The characteristics of the formation, development and attenuation of shock wave, as well as the brake efficiency, induced by different launch pressures are analyzed. The launching platform of the first-stage gas gun was built experimentally, and the muzzle brake efficiency was tested. The results show that the maximum deviation of the simulated brake efficiency is less than 1.25% compared with the experiment, and the dynamic development of the brake flow field highly agrees with the experiment. The brake efficiency increases linearly with the launch pressure. For the muzzle brake with a side hole angle of 120° and the diameter of 16 mm, when the launch pressure increases from 5 MPa to 10 MPa, the brake efficiency increases from 4.87% to 12.71%.
