METHOD FOR TESTING AXISYMMETRIC SHELTER AMMUNITION WITH AXISYMMETRIC AMMUNITION DISPERSION FIELD FOR AIRSTRIKE Russian patent published in 2023 - IPC F42B35/00 

FIELD: methods for testing fragmentation munitions for airstrike.

SUBSTANCE: invention can be used in testing axisymmetric munitions of natural and given crushing with axisymmetric fragmentation fields. The ammunition is installed in the centre of the profiled target wall, marked into zones corresponding to the directions of fragments expansion in the accepted coordinate system. The ammunition is installed so that its longitudinal axis coincides with the longitudinal axis of the profiled wall. Profiled target wall is semi-cylindrical. Symmetrically to the zones of the semi-cylindrical longitudinal wall, simulators of compartments of the first type, second type and third type are installed. On the front surface of the target wall zones located symmetrically to the simulators, the dimensions of the input walls of the compartment simulators are applied and their coordinates are determined in the accepted coordinate system. The ammunition is detonated. Hits and the number of fragments in each of the marked zones are recorded. The size and area of holes from fragments are measured. Signals are recorded from electret sensors placed in the corresponding zones of the target wall and equal in size to them for further processing. The quantitative characteristics of the fragmentation field by masses, velocities, shape and size of the fragments are evaluated. A qualitative assessment of the phenomenon of an airstrike of a fragmentation field of ammunition in simulators of the design compartments is performed according to the principle "destroyed", "partially destroyed", "not destroyed", for each of the simulators the total number of fragments N, masses, speeds, shapes and sizes of all falling into the input walls of fragment simulators are determined, for each of the simulators the energy values of the flow of fragments covering the wall of the compartment simulator, the values of the specific energy of the flow of fragments covering the walls of the compartment simulators are determined, the indicator of the air impact phenomenon for each of the simulators used in the tests is determined, the fact of destruction or non-destruction or partial destruction of structure compartment simulators by the phenomenon of air impact is correlated with specific energy values for all fragments that got into the simulators.

EFFECT: increased informativeness of the method due to additional determination during testing of particular characteristics of the airstrike phenomenon that occurs in the compartments of the design of typical targets when they interact with the fragmentation field of the tested ammunition.
