METHOD FOR EVALUATING THE PENETRATING EFFECT OF FRAGMENTS OF AN AXISYMMETRIC FRAGMENTATION MUNITION WITH AN AXISYMMETRIC FRAGMENT SCATTERING FIELD Russian patent published in 2023 - IPC F42B35/00 

FIELD: testing of fragmentation munitions with axisymmetric flight of fragmentation.

SUBSTANCE: to implement a method for assessing the penetrating action of fragments of an axisymmetric fragmentation munition with an axisymmetric field of expansion of fragments the ammunition installed in the center of a semi-cylindrical profiled target wall is detonated. The wall is divided into zones corresponding to the directions of the expansion of the fragments, symmetrically to which a semi-infinite obstacle simulator is installed, simulators of compartments with vital units of the first and second type. On the front surface of the zones of the target wall the dimensions of the input walls of the indicated simulators are applied, their coordinates are determined. Registration of hits is made, as well as trapping and counting of fragments falling into each zone, the size and area of holes, recording and processing signals from electret sensors, determination of the kinetic energy of the fragmentation field of destruction, covering the input walls of the simulators, the maximum thickness of a monolithic barrier of finite thickness which the fragmentation field of ammunition is capable of penetrating, the fact of impact for simulators of compartments with vital units; the fact of impact is correlated with the energy of the fragmentation field of destruction. For simulators the values of the parameters of the behind-barrier fragmentation field are clarified in the form of the maximum total thickness of the demolished barriers which the fragmentation field is able to penetrate and the regression dependences of the estimate of the sectional area of the fragmentation field behind the barrier capable of hitting vital units located in the target compartment.

EFFECT: determination of quantitative characteristics of the fragmentation field by masses, velocities, shape and size of fragments for axisymmetric ammunition with axisymmetric fragmentation fields, as well as determination of the penetrating effect of the fragmentation field of the tested ammunition.
