METHOD OF DETERMINING CHARACTERISTICS OF FRAGMENTATION FIELD OF AMMUNITION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: method consists in placing of a semi-cylindrical target made in the form of N sectors of proximity sensors and determination of a differential law of distribution of the fragments on the directions of emission in each serial of the fragmentation ammunition field on the basis of fixation of coordinates of triggered sensitive elements of photodetectors line in the plate plane. Then the mass of the fragments is determined. Then the distribution law of the fragments by weight is determined in each serial of the fragmentation ammunition field. Then the average weight of the fragment is determined on the basis of the law of distribution of the fragments on their weights. The density flux of the fragments is determined. Then the mathematical expectation of the number of damaging fragments falling into the goal is determined. The device comprises a blasting chamber, an initiation device and the ammunition, a personal computer, a radar-location velocity metre and a semi-cylindrical target made in the form of contactless sensors with N sectors, N blocks of primary processing of information. The blasting chamber has a slit which width and length enable to capture a part of fragmentation ammunition field. The radar-location metre consists of sequentially connected antennas, a high-frequency generator, a unit of broad-band amplifiers, n filters, the first inputs of n keys, and the second inputs of n keys are connected to the output of the initiation device. Outputs of n keys are connected with n inputs of the personal computer.

EFFECT: increase in informational content of the tests.
