Improving the Flight Performance of Projectiles
Abstract
The BRL has been conducting experiments on spin stabilized projectiles using a new boattail shape called the Non-Conical Boattail. This boattail improves the aeroballistic characteristics of the projectile so that longer ranges are attained and heavier payloads can be flown to the target with good accuracy. Many of these experiments have been carried out on 155mm diameter full bore projectiles, but the aerodynamic characteristics can be applied to this configuration in any diameter including subcalibered projectiles. The new boattail also provides a better configuration than a conical boattail for imparting spin as well as forward velocity to the projectile through a saboting system. In this report, the aerodynamic and aeroballistic characteristics of the new projectile as obtained from aeroballistic ranges, wind tunnels, and full range flights are summarized and compared to a similar conical boattail projectile.
