Abstract

A non-energetic smoke fill composition including a resin, a curing agent, a metallic filler, and a non-metallic filler, wherein the smoke fill composition is configured to be inserted into any of an artillery shell, a mortar cartridge, a gun cartridge, and in general an ogive of a projectile, and wherein the smoke fill composition is configured to be disseminated by a fuze and a supplemental charge to produce a signal visible in both day or night conditions.

First claim

What is claimed is:

1. A non-energetic smoke fill composition, comprising:
a resin;
a curing agent;
a metallic filler; and
a non-metallic filler, wherein said non-metallic filler comprises any of powdered boron, powdered carbon, and powdered phosphorus and is in the range of 10% to 80% parts by weight:
and;
wherein said smoke fill composition is configured to be disseminated by a fuze and a supplemental charge to produce a signal.

2. The composition of claim 1 , wherein said signal is visible in both day and night conditions.

3. The composition of claim 1 , wherein said smoke fill composition is configured for use in a 155 mm training round.

4. The composition of claim 1 , wherein said resin comprises any of epoxies, polyesters, and polyurethanes.

5. The composition of claim 1 , wherein said smoke fill composition is inert.

6. The composition of claim 1 , wherein said metallic filler is configured to produce smoke and is in the range of 10% to 80% parts by weight.

7. The composition of claim 6 , wherein said metallic filler comprises any of powdered aluminum, powdered magnesium, powdered magnesium-aluminum alloy, powdered titanium, and powdered ferro-titanium alloy.

8. The composition of claim 1 , wherein said curing agent comprises any of: medium viscosity polyamide; a low viscosity cycloaliphatic curative; diacyl peroxides; aliphatic, alicyclic and aromatic amines; imidazoles; polymercaptans; and aromatic, alicyclic and aliphatic anhydrides.

9. The composition of claim 1 , further comprising weight fillers, said weight fillers selected from high density metals, microballoons, and borosilicate glass spheres.

10. The composition of claim 1 , wherein said smoke fill composition is configured to be inserted into any of an artillery round, a mortar cartridge, a gun cartridge, an artillery shell, and an ogive of a projectile.

11. The composition of claim 10 , wherein said artillery round, mortar cartridge, gun cartridge, artillery shell, and ogive of as projectile are training rounds configured to have ballistic similitude with a wartime round.

12. The composition of claim 1 , wherein a density of said smoke fill composition matches a density of an explosive, and wherein said smoke fill composition is configured to replace said explosive.

13. The composition of claim 1 , wherein said smoke fill composition forms a solid inert block.

14. The composition of claim 1 , wherein said smoke fill composition can be manufactured, transported, and stored as a non-hazardous material.

15. The composition of claim 1 , wherein said smoke fill composition has a reduced toxicity when compared to high explosive materials.
