Abstract:

Firings of 20mm projectiles with a tubular hole along the axis were conducted to measure the effect of such a hole on the retardation. The drag coefficient is found to decrease as the tube diameter increases. Comparison is made with the Standard 20mm ball projectile and a 20mm with a 30 deg conical windshield.
