  • Detonator device and method for making same
    Patent number: 5359935
    Abstract: A device for generating a shockwave for initiating detonation of a main explosive charge and a method for producing same are provided. A device according to the instant invention is capable of producing a more planar wave front than is possible according to the prior art. Also, the wave front generated by such a generator flattens out in less time than in the prior art, and therefore the weight and axial length of a warhead equipped with a generator according to the instant invention may be substantially reduced without a corresponding reduction of the detonator's explosive yield.
