Abstract

Abstract

To study the penetration and energy release effect of W/ZrNiAlCu metastable reactive alloy composite fragment against RHA target, the penetration tests using high-speed camera and ballistic gun system were conducted. And the energy equation and Arami-Erofeev equation was produced to theoretical analyze the results of penetration tests. The results show that the combustion reaction of fragment is induced by penetration process, which initiates distinct flame in the front of the target and behind the target. The brightness and scope of flame are enhanced with the increase of impact velocity. The relationship between impact velocity and plug velocity conforms to the penetration equation deduced by energy method. The theoretical ballistic limit velocity is 987.1 m/s. The efficiency of reaction is enhanced with the increase of impact pressure within the experimental velocities, which consistent with the experiment.
