Study on the damage effects of Zr-based reactive casings warhead on typical targets

This paper focuses on the damage effects of Zr-based reactive material casing and 45 steel inert material casing on typical targets with the same mass ratio of casing to charge are studied. Because of its unique mechanical properties and high energy density, Zr-based reactive materials can rapidly produce chemical reactions and release a large amount of energy under explosive driving, thus significantly improving the warhead's destructive power. The parameters of explosive fireball were observed by overpressure test and high speed photography, the shock wave damage effect, fragment damage effect and energy release characteristics of Zr-based reactive materials driven by explosion are analyzed theoretically. The experimental results show that the Zr-based reactive material casing has obvious advantages over 45 steel inert material casing in fragment damage and shock wave damage to typical targets under the same mass ratio of casing to explosive, can increase the damage to a typical target. The method of calculating the velocity and other parameters of air shock wave at the midpoint of the sensor range by high speed photography can provide a theoretical basis for evaluating the damage power of the reactive material casing driven by explosion. The test results show that the reactive material casing has a good application prospect in realizing high-efficiency damage.
