Effect of ignition delay runaway of traveling charge on gun firing safety

Abstract In order to promote the engineering application of dense traveling charge technology, a structure scheme with central hole was proposed. Aiming at this scheme, interior ballistic model established, and performance advantages new effect inconsistent ignition delay time on were analysed. The calculated results show that combustion is feasible scheme. Compared end face burning rate reduced mass ratio total increased, which can effectively increase muzzle velocity projectile improve gun. While control precision 0.01ms level, puts forward higher requirements for design processing slow-burning layer. runaway will have great influence gun, especially if too small, it cause premature charge, resulting in high secondary pressure peak, not conducive safety artillery launch. This study provide guidance delayed mechanism based slow material.
