Abstract : In static and dynamic firings of smooth and fluted cones, the latter penetrated about 2.5 in. less than expected. In a bearing evaluation, double- body projectiles were fired at a 1700-fps muzzle velocity to impart a 240-rps spin to the rotating member. The cages apparently presented the bearings from functioning properly. The Timken T127 appeared usable but not as satisfactory as the DRC 389 assembly. Scaling studies were begun to determine the effect of size upon the penetration-cone and charge behavior.
