REACTIVE FOCUSING WARHEAD CONCEPT
United States Patent 3664262
A warhead containing two components, each of which is explosively inert ae but which explode when combined. Upon detonation of the warhead the components are propelled along separate paths to a point near the target where they combine and explode to extend the destructive radius of the warhead.

STATEMENT OF GOVERNMENT INTEREST
The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes therefor.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to warheads and, more particularly, to warheads having a greater radius of destruction.
2. Description of the Prior Art
The prior art has long been concerned with the problem of producing a warhead which would destroy a target at great distances or which would more certainly destroy a target close to the blast. To solve this problem, the prior art has provided shaped charge warheads, rod warheads, warheads containing secondary warheads which are propelled outward by the blast of the primary warhead and later detonated themselves, and various other types of warheads.
SUMMARY OF THE INVENTION
Applicants' have invented another type of warhead having magnified destructive effects on targets both near to and far from the blast. The warhead of the present invention contains two separate materials, each of which is explosively inert alone. These materials are carried on the warhead so that upon detonation of the warhead they are propelled along separate paths to an area where they are combined. The materials are such that upon combination they produce a secondary explosion or reaction, thereby extending the destructive radius of the warhead.
An object of the present invention is the provision of a warhead which will destroy targets relatively far from the point of detonation of the warhead.
Another object of the present invention is the provision of a warhead which will more effectively destroy targets relatively near to the point of detonation.
A further object of the present invention is to provide a warhead which will produce a secondary explosion after detonation of the warhead.
A still further object of the present invention is to provide a warhead which will, upon detonation, propel two separate reactive components together to create a reaction.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 illustrates schematically the concept of applicants' invention; and
FIG. 2 shows one form in which applicants' invention could be adapted for use in a warhead.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 which illustrates applicants' inventive concept shows two layers of explosives 11 having thereon layers of material 12 and 14, each of which is explosively inert alone but which, when combined, produce an explosive reaction. As can be seen from the drawing, when explosive layers 11 are detonated, layers 12 and 14 are propelled along separate paths to area 15 where they combine and produce an explosive reaction.
FIG. 2 shows one way in which applicants' invention can be adapted for use on a warhead generally designated by reference numeral 16. The warhead contains an explosive core 18 and is of generally hour glass configuration. Around one half of the hour glass is layer 19 of one of the explosively reactive elements and around the other side of the hour glass is layer 20 of the other of the explosively reactive elements. The warhead is preferably detonated at each end by detonators 21 and 22. Such detonation results in the material in layers 19 and 20 being propelled toward each other to meet at plane 24 which passes through the center of the hour glass warhead. Upon meeting, elements 19 and 20 explosively react to produce secondary explosions thereby extending the destructive radius and effects of the warhead.
Obviously many elements can be used for layers 19 and 20. The only requirements are that such elements be reactively inert alone and react when they are combined. Also, they should not explode or be destroyed by the impact or other effects of detonation of the warhead. In practice, applicants' have made one layer from an oxidizer and the other layer from a fuel. For example, inhibited red fuming nitric acid has been used as the oxidizer and a conventional rocket fuel designated MAF (mixed amine fuels) has been used as the fuel element. Another combination was 72 percent perchloric acid as the oxidizer and aviation gasoline as the fuel. Obviously, these reactive elements may have to be carried in a binder material to make them suitable for being placed in layer form on the warhead. A slight variation of applicants' concept would involve taking the elements of thermite, i.e., iron oxide powder and aluminum and making one layer out of each of these elements. These would be propelled by the explosion to collide with one another along plane 24. This collision would induce a reaction between the iron oxide powder and aluminum.
Many modifications and variations of applicants' concept are clearly possible in light of the above teachings. For example, layers 19 and 20 do not have to be entirely of one material. It could be possible to make layer 20, for example, out of alternating rings of oxidizer material and fuel material and to do the same thing with layer 19. This could well result in a greater mixture of the reactive elements upon detonation of the warhead and therefore a greater secondary explosion. Also, other ways of propelling the elements towards one another are possible and applicants' do not intend to limit the invention to the hour glass configured warhead. Any warhead configuration which could propel the separate elements for mixture together could be used with applicants' inventive concept. Furthermore, it would be possible to use more than two elements, each of which is explosively inert and which combine to produce an explosion. For example, three or four such inert elements could be propelled toward one another to produce secondary explosions upon combination.
The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes therefor.
