Debris-free combustible aerial shell
First Claim
Patent Images
1. A pyrotechnic projectile comprising:
- an aerial shell comprising at least one combustible layer of material, the at least one combustible layer comprising an outermost combustible layer surrounding the at least one combustible layer, the outermost combustible layer configured to ignite on substantially an entire outer surface, the outermost combustible layer comprising a relatively higher combustion rate than the at least one combustible layer;
the at least one combustible layer surrounding and containing at least one pyrotechnic effect and a dispersive explosive charge;
the at least one combustible layer comprising a combustible material configured to burn substantially throughout the at least one combustible layer; and
wherein the at least one combustible layer is configured to burn through a thickness at a preselected rate to thereby ignite the dispersive explosive charge.

14. A method of forming a pyrotechnic projectile comprising:
-
forming an aerial shell comprising at least one combustible layer of material, said forming comprising forming an outermost combustible layer surrounding the at least one combustible layer, the outermost combustible layer formed to ignite to thereby subsequently ignite the at least one combustible layer on substantially an entire outer surface, the outermost combustible layer comprising a relatively higher combustion rate than the at least one combustible layer; forming the at least one combustible layer surrounding and containing at least one pyrotechnic effect and a dispersive explosive charge; wherein the at least one combustible layer is formed to burn substantially throughout the at least one combustible layer; and wherein the at least one combustible layer is configured to burn through a thickness at a preselected rate to thereby ignite the dispersive explosive charge. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
