ABSTRACT:
An improved projectile suitable for use in artillery pieces, though preferably in the higher calibres, is disclosed wherein projectile range upon launching by the gun is considerably extended by means of a propellant rocket motor in combination therewith which motor is characterized by containing in its combustion chamber a flowable propellant charge in the form of a fluidizable, shapeable propellant charge composition which under the high radial acceleration forces imparted to the projectile when fired from a rifled gun barrel, flows and shapes itself into the shape of a hollow cylinder and, when ignited in flight, burns in the manner of a solid propellant grain of the same shape to aid in propelling the projectile a greater distance than is possible with the gun alone.
