NON-DESTRUCTIBLE DETONATION TRANSLATOR Russian patent published in 2017 - IPC F42B3/00 C06C5/04 

FIELD: blasting.

SUBSTANCE: non-destructible detonation translator contains a detonating line charge of blasting explosive in a metal case that has an outer coating of nonmetallic material with an impedance substantially less than that of the case metal, in the form of a filament winding made of high-strength synthetic fibers of an ultrahigh-modulus material. At the ends of detonating line charge the charge-amplifiers made in the form of thin-walled metal caps with a combined charge of blasting explosive, consisting of two pressings of different densities, are placed. Detonating charge is placed in a thin-walled metal tube, tightly put on the filament winding. Charges-amplifier are installed in the internal cavity of the tips fixed to the ends of the metal tube by means of a threaded connection, wherein the bottom parts of the caps projecting beyond the tips. The bottom part of the internal cavity of the tips has a tapered constriction, directed by the apex towards the metal tube. In the internal cavity of each tip there is a locking device made in the form of a locking ball and a sliding sleeve. The detonating line charge of blasting explosive is located in the axial channel passing through the cone-shaped constriction and sliding sleeve, and each tip is provided with a mounting nut with external thread, which secures the detonation translator in the on-board pyroautomatic system. The equipment of detonating line charge is a thin 0.5-0.7 mm cord of a highly sensitive and highly blasting elastic explosive with a small, about 0.2 mm, critical diameter of detonation.

EFFECT: reducing the level of shock wave loads, excluding the possibility of device case layers destruction and increasing its reliability, improving the mass-dimensional characteristics.
