METHOD TO TEST FRAGMENTATION AMMUNITION WITH AXISYMMETRIC FIELD OF FRAGMENT EMISSION AND BENCH FOR ITS REALISATION Russian patent published in 2013 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: method includes blasting of ammunition installed into the specified position in the centre of a profiled target wall marked into zones corresponding to directions of fragment emission in the accepted system of coordinates, registration of hits, capturing and count of fragments getting into each area, measurement of dimensions and area of holes. Evaluation of qualitative and quantitative characteristics of the fragmentation field by weights, speeds, shape and size of fragments is realised by means of registration, recording and further processing of signals from electret sensors placed in appropriate zones of the target wall and equal to them in dimensions. The bench for realisation of the method comprises a profiled target wall made as capable of adjustment of curve radius. The wall lining is made in the form of a set of electret sensors, separately electrically connected with a computerised system of registration and recording. Sensor electrodes are made from mechanically fine-dispersed metal particles.

EFFECT: increased accuracy of measurements.
