The Initial Velocities of Fragments from Bombs, Shell and Grenades,
Abstract
The initial velocities of fragments from bombs, shell and grenades were studied in order to compare efficiencies of the various projectiles. Initial velocities may be predicted from a knowledge of the dimensions of the metal casing and the character and quantity of explosive. A theory was put forward that the contribution to the kinetic energy made by the detonation of unit mass of explosive is independent of the size of the projectiles. In a large bomb the explosion gases have actually more kinetic energy than the fragments. A simple expression is found for the average initial velocity in terms of the charge-weight ratio, C/M; this expression is found to agree with the experimental data fairly well over the whole range from C/M = 0.06 to C/M = 5.6.
