    Abstract
  • On the basis of explosion gas dynamics, the movement of flyer plate is studied using characteristic curve difference method in this paper. In the process of difference, the basic assumption of steady detonation is used to study the law of flyer plate movement. According to the theory of two-dimensional steady flow, the compatibility relationship of characteristic curves is derived which belongs to general equation of state, with Mach number taking the place of the density of detonation gas. The movement parameters of flyer plate accelerated by TNT and emulsion explosives are calculated by the difference programs of characteristic curve. In addition, the flying postures of flyer plates driven by the two kinds of explosives at different mass ratio are also analyzed and compared with the calculated results by Ritchter's formula in terms of its accuracy.
