Abstract : Tank weapons have increased lethality in comparison to weapons of the past because of the development of high performance tank cannons and associated ammunition. This increase in lethality is due, in part, by the development of the armor-piercing, fin stabilized, discarding sabot (APFSDS) kinetic energy (KE) projectile. The US ARMY presently uses the M829 as one of its main KE ammunition in the MlAl tank. The M829 projectile sabot configuration is the double ramp design. The double ramp design with its central bulkhead and forward scoop bore rider provides dynamic stability during the launch cycle. This paper examines the simulated lateral dynamics of two particular APFSDS KE rounds: the existing M829 a double ramp sabot design projectile and a conceptual puller sabot projectile. The lateral dynamics of these two KE rounds are simulations as fired from two particular 120-mm tank cannons. The simulations are performed by the Little RASCAL gun and projectile dynamics program. This program models dominant lateral loads of gun dynamics and the projectile interacting with the barrel. In-bore projectile lateral dynamics are predicted by the program which at muzzle exit provide initial launch conditions. Comparisons of the two KE projectile are made of mechanical flexure and shot exit conditions.
