Research on the Damage Effect to Supersonic Missile Engine Cabin by Discrete Rod Warhead

For study the damage effect of discrete rod warhead to supersonic missile engine cabin, the rods attacking the supersonic missile engine cabin were simulated by using ANSYS / LS-DYNA software. Acquired the influence rules that the postures of the rods and the number of the rods attacking the target to damage the supersonic missile engine cabin. The results show: the postures of the rods have great influences to damage the supersonic missile engine cabin; When the rods are straight circular permutation, the rods have the best damage effect to engine cabin; the smaller of the angle between the rods vertical axis and the engine cabin vertical axis, the damage ability is the strongest. Really not the more number of the rods attack into the supersonic missile engine cabin, the damage effect is the better; contrasted the conditions with the same rotation angles, the damage effect to engine cabin, the conditions of 4 rods attacking into the engine cabin are better than the conditions of 5 rods attacking into the engine cabin.
