Abstract
The invention is a projectile stabilizing fin formed with a laterally exting flat, triangular shaped tab positioned so that one point of the triangle points in the direction of the intended projectile direction and tilted so that air flow will impinge on the tab surface and cause the projectile to spin. Such construction is particularly useful for projectiles launched from smooth bore guns at high Kinetic Energy.
