A Numerical Study on Projectile Penetration into Underwater Torpedo Warhead

Abstract Underwater torpedo interception could be conducted by shell perforation or even warhead impact detonation with high speed projectiles. This work deals the projectile water entry and sequent penetration into underwater whereby both aluminium explosive are numerically studied. The model aluminum validated against test data for penetration. Targets located under 20 cm depth where shells air-back while has explosives inside shell. Four kinds of different nose shape tungsten projectiles used simulation, revealing that ogival have superior performance as well than conical Numerical predictions shed some light on optimization design velocity torpedoes.
