Abstract
Abstract A hollow charge construction in the form of a missile includes a symmetrical explosive charge having a conical forward liner and a rear spherical recess carrying an inert insert made of a material such as silicon rubber and providing guidance of the detonation waves. A detonator is arranged in the axis of rotation of the explosive charge cavity and the conical hollow charge liner and the inert insert which is arranged in the conical cavity. The explosive charge is enclosed by an aerodynamically designed cylindrical housing with a double hood portion. The detonating device is actuated by contact between the outer and inner hood walls and by transmission of a detonating pulse through an electric line which traverses the hollow charge in a longitudinal direction. The detonator in a form of a compressed charge is held centrally within a rear closing cover of the housing. The inert insert is made up of many parts having intersecting surfaces which extend at right angles to the axis of rotation of the charge.
