title = "Analysis of underwater projectile experiment using one stage light gas gun and numerical simulation",
abstract = "One stage light gas gun is an important device for experiments of low-speed supercavitation projectiles. After a reasonable simplification to the gas gun, movements of the projectile in the barrel have been analyzed and the relationships between the initial pressure of the gas gun and the exit velocity of the projectile were obtained. For meeting the velocity difference between at the gun exit and water-entry, a speed impairment factor was employed. The results of the adiabatic analysis of the simplified gun show that the best ratio between gun chamber volume and the barrel length is related to the gas thermodynamic process and the gas residual pressure has relation to the gas thermodynamic process. The low-speed supercavitation projectile experiments have been carried out. The movements of the projectile in the gas gun and the supercavitation shape and projectile speed after water-entry have been numerically simulated.",
