METHOD OF FRAGMENTATION AMMUNITION TESTING AND BENCH FOR ITS REALISATION Russian patent published in 2013 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: ammunition is installed in the centre of a shield target layout, which is arranged in the form of a semi-cylindrical vertical wall, the ammunition is placed in a horizontal position on a stand with height equal to half of wall height, ammunition axes are matched with a straight line connecting vertical ends of the wall, additionally two contactless sensors are introduced, which are installed at the specified distance between each other and are arranged in the form of semi-cylindrical vertical walls, comprising N - sectors, which contain perpendicularly arranged lines of photodetectors and radiators, speeds of fragment echelons are determined in each sector, due to fixation of time moments of actuations of photodetector elements of the first and second sensors in process of missile fragment motion towards the target. Further the number of missile fragment echelons is determined, spatial positions are fixed for actuated sensitive elements of photodetector lines in the plane, data is transferred to a micro PC, coordinates of fragment motion are determined, and geometric dimensions of fragments are determined.

EFFECT: increased efficiency of experimental data processing.
