Design, Fabricate, and Test Projectile, 40-mm, M433 HEDP with Incendiary Enhancement
Abstract
A projectile, 40-mm, HEDP, M433 with incendiary enhancement was designed, modified and tested. The purpose was to determine the degree to which terminal effectiveness of the round was enhanced by adding incendiary material to the apex of the shaped charge cone. The parameters of incendiary length, diameter, geometry, material and munition standoff were varied. Evaluation was made of the functional parameters of penetration, thermal output and peak pressure and impulse. The optimum incendiary round was one assembled with a tubular sponge zirconium incendiary slug having a uniform I.D., one-half inch in diameter by five-eighths inch in length. A round assembled to these specifications will produce a significant increase in pressure and temperature rise within an enclosed target, and the presence of burning incendiary particles will increase the round's potential for setting fires within the target.
