Aerodynamic Characteristics of .50 Ball, M33, API, M8, and APIT, M20 Ammunition.

Abstract The caliber .50 Ball, M33, API, M8, and APIT, M20 munitions were recently fired in the BRL spark photography ranges, to determine the complete aeroballistic characteristics required for a fire control study. Aerodynamic drag, gyroscopic stability, dynamic stability and yaw damping rates were determined at supersonic, transonic and subsonic speeds. The observed non-linear behavior of the Magnus moment coefficient predicts a slow arm limit cycle yaw at transonic and subsonic speeds. (aw)
