Experimental Research on Armor Penetration Aftereffect Produced by Depleted Uranium Alloys Liner Shaped Charge

In order to investigate the armor penetration aftereffect of depleted uranium alloys liner, a series of aftereffect experiments are conducted using depleted uranium-Ni alloys liner.The results show that, a high-speed and high-temperature flaming grain bundle is formed after depleted uranium alloys jet penetrating the steel stick, and the fire ball has great incendiary power.Pressure of the inside space barely change after depleted uranium alloys jet penetrating the closed armor target, but the temperature of the location towards shaped charge jet has increased 15℃ in 0.2 s, and the whole temperature of the armor target has increased 2.5℃ eventually.
