Abstract:

The report presents the results of ballistics range and wind-tunnel measurements of the static force and moment and the pitch-damping, roll-damping and Magnus moments for a General Purpose 20-Millimeter Projectile. Data are presented for a Smooth and Basic configuration. These aerodynamic data are used in a special digital computer program to rapidly assess the stability of the projectiles over various mission profiles. The normal-force and pitching-moment derivatives are evaluated, theoretically, by Woods method and compared with the measurements.
