| Abstract: | In order to show the damage advantage of linear warhead compared with focused warhead in air defense and anti missile operations, the damage gain of linear fragment perforation distribution to typical air targets is studied. Based on the force concentration effect of perforated structure, the typical targets of air targets damaged by linear warheads and focused warheads are designed theoretically, and the tensile and bending resistance of typical targets under different perforation distribution conditions are simulated. The results show that the linear warhead is superior to the focused warhead when the hole center distance of fragments is less than 3.16 times the aperture, the loss ratio of tensile strength and bending strength of the corresponding target is 2.1 times and 2.76 times that of the focused warhead, when the hole center distance is greater than 4.21 times the aperture, the damage of bending strength of the target is about twice that of the focused warhead. |
