Fragmentation Effects of the 75MM H. E. Shell T3 (M48) as Determined by Panel and Pit Fragmentation Tests

摘要

By fragmentation firings in semi-circular wood panels, the fragment density was determined as a function of the angle with the axis of the shell, the distance, and the remaining velocity. Considering the fragment densities with regard to the angle with the shell axis, the fragments are concentrated in three main classes, commonly designated as nose, side, and base sprays. With regard to the variable of distance, the densities decrease with the distance, the decrease in total number of hits in the side spray averaging about 55% between the 15 and 120 ft. panels. The general effect of remaining velocity is to reduce the number of fragments in the base spray, to shift the side spray forward, and to increase the number of fragments in the nose spray. (Author)
