The zero dimension model of regenerative liquid propellant auxiliary chamber launching process is established and numerical simulation is conducted by Runge-Kutta. The calculation results indicate that it can increase the projectile muzzle velocity. The calculation results are consistent with experimentation results. At the same time, the effect of auxiliary chamber's structure parameters are analyzed in this paper and the basic rules are given.
