Aerodynamic Characteristics of the 30mm, XM788 Projectile

Abstract

Spark range tests of the 30mm, XM788 projectile were conducted to determine the small-yaw aerodynamic properties at supersonic, transonic, and subsonic speeds. The XM788 projectile, fired from the XM230E1 barrel is adequately gyroscopically stable at all speeds tested. The data show that a slow-arm (precession) limit-cycle yaw exists at low transonic and subsonic speeds. The drag increase due to the limit-cycle yaw is discussed.
