The Effect of a Sub-Caliber Cylindrical After-body on the Behavior of Spin-Stabilized Projectiles

Abstract

Range, wind tunnel, and instrumented free-flight tests have shown that a subcaliber boom at the base of a spin-stabilized projectile will produce significant changes at both small and large yaws. Almost all properties, but in particular the static and magnus moments, are affected. These aerodynamic changes, together with the inertial properties of the shell, are shown to affect both the static and the dynamic stability adversely.
