Aeroballistics of Corkscrew Projectiles.

Abstract

Preliminary wind tunnel and aeroballistic range tests on a new and novel exterior projectile shape have shown that this 5-caliber to 8-caliber long shape has extremely good aerodynamic characteristics. It not only has very low drag, but also low pitching and Magnus moments which in turn yield good gyroscopic and good dynamic stability. Extrapolation of the data to longer lengths indicates that 10-caliber to 12-caliber long projectiles having this shape can be flown with satisfactory stability. (Author)
