Protection effectiveness of a new explosive reactive armor against penetration of long-rod projectiles with small yaw angles

A new explosive reactive armor (ERA) structure was designed. A series of dynamic analyses were carried out on the interferences of the new ERA structure with the motion velocity and attitudes of the long-rod projectiles, the corresponding dynamic equations were obtained for the long-rod projectiles in the mass conservation condition, and the protection effectiveness of the new ERA structure was experimentally validated. Investigated results show that the new ERA can disturb effectively the motion attitudes of the long-rod projectiles with small yaw angles and induce their kinetic energy decrease markedly.
