Edge Effects on ERA-Sandwiches

摘要

The momentum transfer of thick flying plates of an ERA sandwich and iterative disturbances of shaped charge jets by thin flying plates are shortly described.Hits on the sandwich plates,out of the centre,in the horizontal direction are not reducing the effectiveness,as long as the high explosive charge is promptly initiated.In vertical directions the author has found out that in case of hits on top or the bottom,where only the front respectively the rear plates are interacting with the jets,the reduction effects in penetrations remain also more or less constant.Changing the azimuth angle up to 30 deg the residual penetrations are also not increased or decreased.
