  • The integrative process of the quiescent projectile accelerated by high-pressure gas to shoot out at a supersonic speed and fly out of the range of precursor flow field was simulated numerically. The calculation method was based on ALE equations and second-order precision Roe method adopting chimera grids and dynamic mesh. From the predicted results, the coupling and interaction among the precursor flow field, propellant gas flow field and high-speed projectile were discussed in detail. And the shock-vortex interaction, shockwave reflection, shock-projectile interaction together with shock diffraction and shock focusing were demonstrated clearly to explain the effect on the acceleration of the projectile.
