EFFECTIVENESS OF PG-7 GRENADE AFTER PASSING THROUGH THE NET-ARMOR-NUMERICAL ANALYSIS

摘要

Numerical analyses have been performed to investigate how the PG-7M grenade interactionwith the net-armor affect the shaped charge jet formation and penetration capability. Twotypes of three-dimensional computer simulations were carried out. The first one includemechanical interaction between the grenade and two commonly used types of net armors.The deformation rate of the warhead and occurrence of the short circuit in a fuse ofpenetrating grenade were estimated. The second type of analyses included the phenomenaof shaped charge jet formation and penetration into RHA plate. Since the simulations werecarried out for both the deformed and undeformed warheads, it was possible to evaluate theinfluence of the grenade deformations on the shape charge jet penetration performance.
