To Obtain Fragment Velocities with Related Masses, and Spatial Distribution of Fragments of Shell, HE, Soviet, 122mm, Models OF-471N, O-462A, and OF-462
Abstract
Shell, 122mm, Soviet, Model OF-471N, Filler TNT, will produce an average side fragment of 121.3 grains, with an initial velocity of 3106 fps, producing an average casualty range of approximately 83 feet. In the panel of 30 foot radius, 5.61 hits per square yard were inflicted, 1.52 of which were perforating. In the panel of 60 foot radius, 1.22 hits per square yard were obtained, 0.33 of which were perforating. The main fragment spray fell between 77 and 103 degrees from the nose of the shell. Shell, 122mm, Soviet, Model 0- 462A, Ammonium Nitrate 90% TNT 10%, will produce an average side fragment of 22. 1 grains, with an initial velocity of 2762 fps, producing an average casualty range of approximately 75 feet. In the panel of 30 foot radius, 21.60 hits per square yard were inflicted, 4.00 of which were perforating. In the panel of 60 foot radius 4.00 hits per square yard were obtained, 0.65 of which were perforating. The main fragment spray fell between 77 and 106 degrees from the nose of the shell. Shell, 122mm, Soviet, Model OF-462, Ammonium Nitrate 80% - TNT 20%, will produce an average side fragment of 100.1 grains, with an initial velocity of 3089 fps, producing an average casualty range of approximately 82 feet. In the panel of 30 foot radius, 3.84 hits per square yard were inflicted, 1.49 of which were perforating. In the panel of 60 foot radius, 0.80 hits per square yard were obtained, 0.37 of which were perforating. The main fragment spray fell between 83 and 106 degrees from the nose of the shell.
