Abstract
A projectile having a spin stabilized gyroscopically stable flight path due to a base flange. With the base flange, the aerodynamic overturning moment about the center of gravity is reduced to increase the gyroscopic stability factor for stable flight. In one application, a medium-caliber untethered human electro-muscular incapacitation (HEMI) projectile has improved effectiveness due to its stable flight from launch to targets. Other applications for damping resulted in significant improvement in ground dispersion of 40 mm projectiles. The increased stability and increased aerodynamic damping reduce coning motion during flight which ensures that the projectile arrives at the target with greater accuracy, and with its nose oriented for effective incapacitation of the target.
