Abstract : A new technique for studying the interaction of a blast wave with a supersonic projectile is described. A conventional shock tube was combined with a ballistic range by installing a smooth bore powder gun in the dump chamber and firing .300 caliber cone-cylinder projectiles toward the driver. The velocity of the projectile, fired into air at 100 mm Hg, was measured near the muzzle and a computer used to provide a proportional time delay before the shock wave was started down the tube. The projectile and the shock wave, each traveling at about 4000 feet per second, met in a 3-inch diameter window. Two spark light sources were used for shadow photography of the interaction. Typical interaction photographs are shown. (Author)
