DETONATING FUSE FOR ELONGATED CUMULATIVE CHARGE (KRASNOV-DETONATOR) AND METHOD FOR INITIATING CHARGE WITH LONGITUDINAL CUMULATIVE GROOVE Russian patent published in 2013 - IPC F42B3/87 

FIELD: weapons and ammunition.

SUBSTANCE: detonating fuse for elongated cumulative charge has input and output for initiating pulse and: includes high-speed explosive. Detonating fuse is equipped with initiating pulse conductors, in which the speed of initiating pulse spreading is, at least, three times less than the speed of detonation of high-speed explosive. The conductor of initiating pulse has such geometrical shape, which provides pulse output from the conductor simultaneously along its entire length. The surface of initiating pulse output of one of the conductors is a natural continuation of initiating pulse output surface of the neighbouring conductor. Detonating fuses are used for initiating a charge with longitudinal cumulative groove. Detonating fuses are located at the charge at a distance from each other, note that the distance value is not less than the width of cumulative groove.

EFFECT: increase of efficiency of initiating elongated cumulative charges.
