Abstract

On the basis of the traditional gas internal ballistic model, the internal ballistic model of supercritical carbon dioxide gas gun is established by adopting the real gas equation of state, and the algorithm for this internal ballistic model is developed for numerical calculation, and the change curves of the bore pressure and projectile velocity with the projectile displacement of supercritical carbon dioxide gas gun are obtained. The principle prototype of the supercritical carbon dioxide gas gun was developed and fired, and the exit velocity of the projectile was measured, and the test results were consistent with the simulation results, thus verifying the accuracy of the model, analyzing the reasons for the errors between the chamber pressure test results and the simulation results, and proposing improvement measures.
