Abstract
A rocket and propellant therefor comprising a body portion formed of a plurality of rings arranged in abutting relationship to form an enclosing wall having a nose and a tail end, a rocket motor positioned within the wall and including a solid propellant arranged in layers with each layer connected to one of the rings, a series of foraminous screens embedded in the propellant and presenting a concave surface to the tail end of the rocket and focusing the propellant gases on the tail end which is adapted to have a burning surface that travels toward the nose end when the rocket is in flight, said screens also controlling the shape of the burning surface by spreading it laterally. The rocket also includes means for controlling the distance of travel by extinguishing the burning surface, means for re-igniting the extinguished rocket including an electrical circuit having wires which connect with a slow-burning fuse layer, and steering means which includes an auxiliary propellant that is discharged through clusters of pipes to change the mass or energy at one side of the rocket tail to swing the tail around and change the direction of rocket travel.

6. A rocket comprising an enclosing wall having a nose and a tail end, a solid rocket propellant contained within said wall and presenting a burnable surface to said tail end, a series of foraminous screens imbedded in said propellant and extending transversely across the interior of each of said rings, said screens presenting a concave surface to said tail end, and a separate re-ignition layer of slow-burning fuse material located between said screens, said rocket propellant comprising a plurality of charges of rapid burning propellant which are spherical in shape with a cone-shaped opening leading to a detonator so as to expel their burning gases in one direction when burning and are dispersed between said nose and tail end to burn successively, and a matrix of slower-burning cushioning material in which said charges are supported and oriented so that their burning gases are expelled toward said tail end, whereby the average rate of burning of said rocket propellant as a whole is intermediate the rate of burning of said charges and said matrix.
-
