METHOD FOR DETERMINING INITIAL VELOCITY MODULES OF STRIKING ELEMENTS IN LOW-VELOCITY FRAGMENTATION FIELDS WHEN TESTING AMMUNITION IN PANEL TARGET ENVIRONMENT Russian patent published in 2023 - IPC G01P3/36 F42B35/00 

FIELD: measurement technology.

SUBSTANCE: invention concerns a method for determining the modules of the initial velocities of striking elements in low-speed fragmentation fields. The method includes photographic registration of rectangular numbered cells of a flat vertical shield and video recording of penetration of the shield by destructive elements, followed by determination of the coordinates of the holes in the shield coordinate system, the moments of time of penetration of the shield and the angles of dispersion of the destructive elements. In addition, using a side high-speed video camera, the departure of destructive elements from the cloud of ammunition explosion products is recorded. In one of the frames, the coordinates of the leading destructive element, ejected and located near the boundary of the cloud of explosion products, are measured. Using these coordinates and the moment of time of the frame, the coordinates of the trajectories of the remaining striking elements at the time of this frame are determined, the path lengths and flight times of the striking elements from the specified frame until they penetrate the shield are calculated, and from these data the modules of the initial velocities of the striking elements are calculated.

EFFECT: increasing the accuracy of measuring the modules of the initial velocities of striking elements.
