Soil Penetration with Gas-Gun Experiment

Abstract


In this paper, we have obtained S-number, which proposed by C. W. Young, of soil target using the high velocity impact test. S-number is commonly used throughout the weapons community as a descriptive term for resistance to penetration. We used wrap-around type gas-gun equipment to perform the penetration test of soil target. The impact and residual velocity of projectile was measured with the high-speed camera. The experimental result shows that the S-number decreases with the increase of soil density. The accuracy of Young's equation for the penetrability (S-number) of soil was verified with the in-house gasgun test.
