Velocity Loss of a 1/2 Inch Model Projectile When It Penetrates 1/32 Inch Cold Rolled Sheet Steel
Abstract
This investigation was made in order to obtain an estimate of the velocity loss of a 4-inch HC Mark 15 projectile penetrating thin plate at velocities well above limit, In order to improve the accuracy of the velocity loss measurement, the experiment was performed with a 1/2-inch model projectile using a ballistic pendulum to measure the momentum loss. Besides giving the desired information, the experiment showed the interesting result that at a striking velocity of 2100 feet per second the velocity loss in 1/32-inch cold rolled steel had a minimum value. It was a surprise to find a minimum at so low a striking velocity. If this is a general characteristic of high velocity penetration of thin plate, it is important not only to the fuse designer but also to the fundamental study of the mechanism of armor penetration.
