The Effect of Initial and Gun Mount Conditions on the Accuracy of Kinetic Energy (KE) Projectiles.

Abstract

The U.S. Army Research Laboratory (ARL) has invested considerable resources in the development of numerical techniques for the prediction of kinetic energy (KE) projectile accuracy. In particular, a validated three-dimensional transient finite element (FE) model of the M256 12O-mm MIAI main weapon system's performance has been created from the trunnions up. This model considers for the first time the gun tube, breech, piston, cradle and mount assembly, along with their associated boundary conditions. This enhanced numerical approach provides new insight into occasion-to-occasion and round-to-round variability in the M256 gun system. Numerical and experimental analysis techniques have been coupled to validate model attributes.
