Abstract: Mechanical enhancement of the burning rate of solid propellants is achieved y the incorporation of limited percentages of heat-expandable beads into the solid propellant matrix. When the flame front reaches an individual bead, the bead which contains an expanding or blowing agent (e.g., pentane, 4,4'-oxybis(benzenesulfonyl hydrazide) (Celogen OT), etc., expands to several times its volume and ruptures. Bead expansion or rupture causes a disruption of the propellant's surface, and the flame can penetrate into the propellant. This penetration results in a major increase in burning rate.

Abstract: Method and coating composition for promoting ignition of deterrent-coated smokeless propellant by applying thereto a nitrocellulose-based igniter component as an overcoat.

Abstract: A solid or semisolid propellant comprising grains of propellant or propellant components bonded together so as to create voids within the propellant volume, said grains bonded together with sufficient strength to substantially delay the fluidization of the propellant by the onset of Taylor unstable burning, said propellant having a rapid burn rate below that associated with Taylor unstable burn. In another embodiment, the grains are held within and the voids are filled with viscous fluid binder such as a petroleum oil, said binder functioning to hinder Taylor unsatable burning and yet permit very rapid burning within the propellant volume.
