Summary:

A key and often quoted metric associated with gun systems is impact point accuracy. The extent of impact dispersion is a complex function of a battery of parameters, including gun geometry and tolerances, the fire control system, projectile manufacturing tolerances, etc. The work reported here investigates potential impact point accuracy improvement for a penetrator-type projectile realized by replacing the rigid nose cone wind screen with a passive gimballed nose. By comparing the impact point dispersion of a rigid projectile with a similar gimballed nose projectile, it is shown that impact point accuracy can be significantly improved. For the example penetrator projectile considered, impact point dispersion is reduced by more than 50%.
