Patent ID: 10775139

Abstract:
An aerial shell comprising at least one combustible layer of combustible material, the at least one combustible layer including 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 including a relatively higher combustion rate than the at least one combustible layer; the at least one combustible layer including an innermost combustible layer surrounding and containing at least one pyrotechnic effect and a dispersive explosive charge; the at least one pyrotechnic effect is preferentially disposed with respect to the innermost combustible layer at least one of immediately adjacent including integral with an inner surface of the innermost combustible layer and spaced away from the inner surface of the innermost combustible layer; the at least one combustible layer configured to burn substantially throughout the at least one combustible layer.
