Studies on Detonation Driven Hollow Projectiles

This study explores the concept of a detonation driven projectile by performing CFD computations for a simple hollow projectile propelled in a pre-mixed detonable mixture. The particular projectile selected for the calculations has a 203 mm outer diameter and is propelled in a stoichiometric acetylene-air mixture at atmospheric pressure. The calculations model the experiments that will be performed at DRES using a 203-mm diameter, 55-caliber gun to fire the hollow projectile, and a long 2-m diameter thin plastic bag to contain the pre-mixed combustible mixture.
