ABSTRACT:
An improved shaped charge for generating a jet. A lens shaped waveshaper is positioned within the explosive material of a shaped charge to modify the shape of the divergent detonation wave into a planar wave or a converging wave. The waveshaper is formed with a low sound speed material having a high index of refraction. By reshaping the detonation wave, the acceleration of the shaped charge liner is increased, and the penetration depth and hole size of the jet can be increased. The shaped charge operates more efficiently, thereby requiring less explosive material than a conventional shaped charge.
