Effectiveness of an ERA-Sandwich with a large distance between sandwich and target
With a distance between a flying plate and main armour in the range of Im, the achieved residual penetration is around 1.5 to 2 caliber, independent of the NATO-angle of 30 degrees, 45 degrees or 60 degrees of the flying plate to the shaped charge axis. This is a surprising result because at near distances a number of explosive reactive armour sandwiches with relatively small high explosive layers have typically strong angle effects in their protection.
