Abstract

Investigations carried out on the high speed entry of spinning cylindrical projectiles are described. The projectiles mainly used were 30°, 60°, 90° conical nose cylinders and flat-nosed truncated cone cylinders. Their specific gravities were from 2.69 to 11.34. To study behaviors of the projectiles, high-speed stereoscopic motion pictures were taken of numerous shot of each of the projectiles at various impact speeds from about 250 to 1000 m/s. Time and position data of the projectiles were read from each film, and using our method of data processing instantaneous position of the projectiles were accurately determined. By comparing each shot of a dense projectile with each suitable shot of a light one, we try to determine the added mass for each projectile shape, but no decided values of them were obtained.
