METHOD FOR 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: ammunition is blasted in a blasting chamber and time dependence of filtered Doppler frequencies of signals reflected from the part of fragmentation field relative to ammunition blasting moment is obtained. Speeds of leading and closing fragments, average speed and depth of the fragmentation field are determined as per time dependence of filtered Doppler frequencies of signals reflected from the part of the fragmentation field relative to ammunition blasting moment. A semi-cylindrical target made in the form of N sectors of proximity detectors is arranged, and a differential law of distribution of fragments as to dispersion directions is determined based on fixation of coordinates of actuated sensitive elements of lines of photoreceivers in the image plane. Then, a law of distribution of fragments as to their mass is determined based on fixation of coordinates of actuated sensitive elements of lines of photoreceivers in space. Time intervals are determined between echelons of the fragmentation field of ammunition based on fixation of sequence of actuations of sensitive elements of the photoreceiver line, which are located along Z axis. After that, dynamics of variation of the law of fragment distribution as to direction and mass is determined based on fixation of the combination of actuated sensitive elements of photoreceiver lines in the image plane relative to Z axis. The device includes a blasting chamber, an initiation device and ammunition, microPC, a radar speed metre and a semi-cylindrical target.

EFFECT: improving test informativity.
