    Abstract
  • Computational design of the cavity in the enhanced hypervelocity launcher was carried out using Eulerian code Multi-Fluid Piecewise Parabolic Method (MFPPM).Three kinds of improved configurations of the cavity were presented with varied angles of the cavity.We numerically investigated the effects of the angle and the thickness of the TPX on the velocity, the velocity difference and the planarity of the flier.Our results show that with the given thicknesses and position of the target, the planarity and the velocity of the flier launched by the second kind of the improved configuration are significantly improved, but the range of the planarity is reduced and the velocity differences of the flier surface are increased so that the desirable planarity cannot be maintained.
