Effect of Spin on the Aerodynamics of the 20mm Projectile,

Abstract

The effect of spin on the aerodynamics of the 20mm projectile was studied from experimental measurements of static stability, axial force, roll damping, Magnus forces and base-pressure surveys made in the NOL Supersonic Tunnel Numers 1 and 2 over a Mach number range of 0.8 to 5 and at Reynolds numbers high enough to ensure a turbulent wake.
