Looking for abbreviations of MEFP? second shot, H854, ussd design #2. Answer (1 of 3): It’s easy to confuse the two, but the traditional shaped charge and the EFP are two different animals, even if they appear superficially similar. Necessary cookies are absolutely essential for the website to function properly. This patent also discloses radial ejection of the EFPs in a 360.degree.
As a rule of thumb, an EFP can perforate a thickness of armour steel equal to the radius of its charge for a copper or iron liner,[8] and armour steel equal to the diameter of its charge for a tantalum liner, whereas a typical shaped charge will go through six or more diameters. [18] This design can be further modified to be similar to US4649828A with multiple cut and bent steel bars lined side by side instead of a singular liner.

[12] A recent development is their widespread use in IEDs by insurgents in Iraq against coalition vehicles.[13].
An EFP, on the other hand, has a liner face in the shape of a shallow dish. Extensive research is going on in the zone between jetting charges and EFPs, which combines the advantages of both types, resulting in very long stretched-rod EFPs for short-to-medium distances (because of the lack of aerostability) with improved penetration capability.
