Electric Charging and Discharging Processes of Moving Projectiles

Every type of missle is electrically charged during free flight. The physical mechanism, leading to the electric charging and discharging effects, was investigated by measuring the electric field surrounding projectiles while leaving the muzzle region, during free flight, and on impact on targets. The electric charge on projectiles is 10-13 108C. Numerous experimental results were obtained with calibers 4-155 mm and velocities 50-120lm/ s. A physical model about the complex charging effects is derived.
