Abstract:
The paper studies the influence of propellant thickness on the interior ballistic performance of an equilibrium launcher,such as,probable error of muzzle velocity,maximum pressure.An interior ballistic model of the equilibrium launcher is established,by which the interior ballistic performance is computed.A test for interior ballistic performance is accomplished.The computational results are in good agreement with test results.By means of Monte Carlo simulation,muzzle velocity and its probable error and maximum pressure in chamber are computed with different propellant thickness.The studies show that the propellant thickness has obvious influence on probable error of muzzle velocity and maximum pressure under the condition of same average muzzle velocity.The quantitative relation between parameters of interior ballistic performance and propellant thickness is acquired,which provides foundation for improving interior ballistic design of the equilibrium launcher.
