Abstract
A shock-wave-reflecting surface and low density matter or gas within the ntal ogive of a shaped charge warhead ahead of the concave liner thereof modifies the speed and consequent distribution of particles in the stretching jet to improve armor penetration capability.
Claims14
A shaped charge warhead of the type having a concave cavity in front of an explosive for producing a jet of rapidly forward-moving particles preceded by a shock wave and a frontal ogive enclosing said cavity, comprising:
- at least one shaped surface in said frontal ogive forward of said cavity dividing said frontal ogive into an inner region and an outer region;
- said shaped surface having a central opening therein communicating said inner and outer regions;
- and
- the shape of said surface and the location and size of said opening being effective to produce regions of reflected shock which interact with said jet to modify at least one characteristic of said jet.

A shaped charge warhead comprising:
- a casing;
- a generally conical metallic liner closing a forward end of said casing, said liner forming an axially symmetric concave cavity in the forward end of said casing;
- an explosive in said casing;
- means for detonating said explosive at the rear end thereof;
- a frontal ogive enclosing the forward end of said shaped charge warhead;
- a shock-wave-reflecting surface in said frontal ogive dividing the volume in said frontal ogive into an inner region between said surface and said liner and a outer region between said surface and the inside of said frontal ogive;
- an axially symmetrical hole in said surface communicating said inner and outer regions;
- said warhead being effective when detonated to collapse said liner into a high-speed jet of particles which pass through said hole preceded by a bow shock wave;
- and
- said shock-wave-reflecting surface being effective to form a reflected shock region which modifies at least one characteristic of said jet.
