Shaped Charge Patents (Class 102/476)
  • Patent number: 4374495
    Abstract: An improved warhead of the type having at least one shaped charge is formed by the shaped charge or charges being positioned within the warhead so that the longitudinal axis of the charge forms an angle of 15 to 50 degrees with respect to the axis of the warhead in its stabilized in-flight attitude.

  • Patent number: 4336209
    Abstract: Explosive bodies for use in hollow-charges are produced by casting a mixture of solid, particulate explosive material dispersed in melted explosive material. The sedimentation of solid explosive in melted explosive is carried out in an undisturbed manner in the mould, i.e. without being influenced by convection currents within the mixture or by collision with the walls of the mould, giving rotationally symmetrical explosive bodies. The detonation front deviation from nominal shape does not exceed 0.05 percent of the body diameter in case of rotationally symmetrical initiation of detonation of the produced explosive body.

  • Patent number: 4297946
    Abstract: An extended shaped charge comprises a tubular body of a one-piece construction with a convexo-concave profile, having thinner portion of its wall on the side of a charge hollow. The profile of the tubular body is formed by conjugate sections of two closed curves having a common symmetry axis and being internally tangent at the point lying on this axis. In a specific case the closed curves are circles.

  • Patent number: 4297948
    Abstract: A spin stabilized projectile is arranged to have variable flight stability. he projectile has a casing with a cavity that contains a given mass of fluid. The cavity is shaped to provide a balanced flow of fluid with respect to the axis of spin as the projectile is trajected. This balanced flow alters the flight stability of the projectile.

  • Patent number: 4291624
    Abstract: An explosive charge is disclosed having air cavities in the explosive material, so situated within the material as to guide the propagation of the shock wave produced by detonation in a predetermined direction.

  • Patent number: 4289073
    Abstract: A disc-shaped warhead adapted for being fired from a barrel weapon, and particularly for being stacked with a plurality of similar warheads in a load-carrying missile for ejection one after the other. The warhead has a plurality of slave missiles disposed in radially directed firing tubes, and a parachute connected to the warhead and causing a directional, braked descent in the target area. Each of the slave missiles has a proximity fuse to detonate it individually after reaching a predetermined distance from the ground or other target.
