Abstract：To thoroughly eliminate the potential hazards caused by misfired naval shells discarded into the sea,a destruction device and method based on a dual-environmental force hydrostatic fuze and shaped charge structure is proposed.The hydrostatic fuze uses a hydrostatic sensor to measure the depth of water,with the safety device releasing at 10 meters and detonating at 12 meters underwater.A shaped charge device with diameter of 42.5 mm is designed,and by AUTODYN software,penetration simulation calculations are conducted with a test projectile made of 40Cr with a thickness of 25 mm,as well as penetration and destruction tests are carried out with the test projectile and 45#steel ingot with a thickness of 50 mm.The results indicate that the initiation depth of the destruction device is accurate,and its destruction capability meets the requirements of active service shells.And this device can eliminate safety hazards,avoid accidents of information leakage,reduce the marine pollution,and has positive military benefits and broad application prospects.
