Deformed Flying-Plate Influence on the Interaction between Jet and ERA

Hong-wei LIU, Yong ZHANG, Jun-hong LUO


The basic physical mechanisms associated with a shaped charge jet penetrating ERA were described in many previous works. In the previous disturb model, the fly-plate was thought as rigid body with no deformation. In according to the physical phenomenal of flying-panel moving, the fly-plate in ERA is deformed. Followed the deformation model of flying-plate, dynamic model of jet disturbances caused by deformed plate of ERA has been set up. A comparison between theoretical results with the numerical simulation and experiment ones show good agreement.
