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.

Fast burning propellants

A line throwing device adapted to be launched from a riot gun or similar tubular launching device comprises an elongated projectile that fits in the tubular launching device, a fin assembly slidably mounted on the body of the projectile such that the fin assembly slides forwardly to permit the rear end of the projectile to be positioned in the launching device for launching and slides rearwardly to a flight stabilizing position at the rear of the projectile as the projectile is launched from the tubular launching device. A rocket engine is mounted in the rear of the projectile for propelling the projectile. An ignition mechanism comprising a conventional shotgun primer cap mounted in a plastic casing fits on the end of the rocket and is ignited by the trigger and firing pin of the gun. A line is coiled in a canister removably attached to the gun, with one end of the line being attached to a harness mounted on the projectile so that the line can be carried to the desired target.
