N2 - In order to compare the forming and penetration process of linear shaped charge jet in three different mediums (in the air/under water/under water with air standoff), three-dimensional numerical simulation models were established using ANSYS/LS-DYNA software. The forming process and penetration performance of linear shaped charge jets are compared and analyzed. Simulation results show that the jet forming performance in the air is better and the jet head velocity is much higher compared with the under-water condition. By adding a hollow tank in front of the metal liner, the jet forming performance under water can be improved significantly. After 60µs of the detonation, the head velocity of three jets are 2750 m/s, 890 m/s and 2600 m/s, and the maximum penetration depths are 0.734DC?0.092DC, 0.91DC respectively.
