Abstract

An interior ballistic model of hydrogen-oxygen combustion of the combustion light gas gun is built to perform numerical calculations by using the Van der Waals equation, the RKS equation and the P-R Equation, respectively. Comparing the calculation results with the experimental results in the literature, it is found that the results obtained through the PR equation are closer to the experimental results. Using the equations of real gases, the influence of different projectile masses, hydrogen-oxygen molar ratios, and initial pressures on the interior ballistic performance are calculated. The results show that the projectile mass will affect the interior ballistic time, the acceleration, and the projectile's initial velocity; the hydrogen-oxygen molar ratio and the initial pressure will affect the interior ballistic time, the maximum bore pressure and the initial velocity.
