Abstract

A method and apparatus for incorporating nanophase elemental materials and metastable interstitial composite materials into projectiles, projectile fragments, ordnance casings, warheads and structural components. The projectile, fragments and casings include an elemental material capable of oxidizing. A coating material that is capable of preventing oxidation of the elemental material and an oxidizing agent may be present and be capable of reacting with the elemental material so that a self-propagating high temperature synthesis reaction from a stabilized solid material is yielded for the purpose of rendering terminal effects or thermal impact to a target at impact.

Claims

1. A projectile for creating a thermal event, comprising:

a. a sleeve;

b. a plurality of fragments arranged in the sleeve, wherein each fragment includes a metastable interstitial composite (MIC) material; and

c. wherein at least 90% of the MIC material oxidizes within 10 seconds of exposure to oxygen to produce the thermal event.

2. The projectile as in claim 1, further comprising an oxidizing agent capable of reacting with the MIC material so as to cause oxidation of the MIC material to produce the thermal event.

3. The projectile as in claim 1, wherein impact of the projectile causes the MIC material to be exposed to air so as to cause oxidation of the MIC material to produce the thermal event.

4. The projectile as in claim 1, further comprising a jacket surrounding at least one of the fragment or the MIC material.

5. The projectile as in claim 1, wherein the fragments are arranged next to one another so as to form a plurality of fitting lines.

6. The projectile as in claim 5, further comprising an energetic component configured to release energy so as to break apart the fragments along the fitting lines.

7. The projectile as in claim 1, further comprising a stress cushion layer between the plurality of fragments.

8. The projectile as in claim 1, further comprising an explosive charge configured for creating an explosion sufficient to cause the MIC material to oxidize to produce the thermal event.

9. The projectile as in claim 1, further comprising a longitudinal bore in the sleeve, wherein the plurality of fragments is arranged around the longitudinal bore.

10. A projectile for creating a thermal event, comprising:

d. a metastable interstitial composite (MIC) material;

e. a binding component substantially coating the MIC material;

f. wherein at least 90% of the MIC material oxidizes within 10 seconds of exposure to oxygen to produce the thermal event.

11. The projectile as in claim 10, wherein the projectile has a specific gravity approximately equal to lead.

12. The frangible projectile as in claim 10, wherein the MIC material is substantially homogeneously mixed with the binding component.

13. The projectile as in claim 10, further comprising an oxidizing agent capable of reacting with the MIC material so as to cause oxidation of the MIC material to produce the thermal event.

14. The projectile as in claim 10, further comprising a jacket surrounding the MIC material.

15. A projectile for creating a thermal event, comprising:

g. a ballistic shape;

h. a longitudinal bore in the ballistic shape; and

i. a metastable interstitial composite (MIC) material surrounding the longitudinal bore, wherein at least 90% of the MIC material oxidizes within 10 seconds of exposure to oxygen to produce the thermal event.

16. The projectile as in claim 15, further comprising a coating material capable of preventing oxidation of the MIC material.

17. The projectile as in claim 15, further comprising an oxidizing agent capable of reacting with the MIC material so as to cause oxidation of the MIC material to produce the thermal event.

18. The projectile as in claim 15, further comprising an explosive charge in the longitudinal bore.

19. The projectile as in claim 18, further comprising a detonator operatively connected with the explosive charge for igniting the explosive charge.

20. The projectile as in claim 15, further comprising a retainer cup in the longitudinal bore of the ballistic shape.
