Abstract

With the experimental study of underwater explosion for confined and unconfined in free field water, the characteristic parameters of explosion, such as the peak pressure of shock wave, the specific shock wave energy, the specific bubble energy, the total specific energy and the relative total energy of the explosives were compared and analyzed. The results showed that the peak pressure are, different for thermoplastic TNT-RDX-Al explosive, fusing TNT-RDX-Al explosive, composite PBX and TNT, Other parameters are, composite PBX, thermoplastic TNT-RDX-Al explosive, fusing TNT-RDX-Al explosive, TNT, The specific shock wave energy, the specific bubble energy, the total specific energy of warhead with shell decreased compared to warhead without shell. The total specific energy decreased 25%, 21%, 15% and 15%. It is obvious that shell is important for underwater explosion effects. Therefore, the influence of shell must be considered and can't be simplified for energy effects of underwater weapons.
