METHOD OF REPRODUCING THE ACTION OF AN AIR SHOCK WAVE OF HIGH DURATION, WHICH IS REFRACTED INTO WATER, ON UNDERWATER ENGINEERING AMMUNITION IN OPEN WATER RESERVOIR CONDITIONS Russian patent published in 2020 - IPC F42B35/00 G01M7/08 G01N29/04 

FIELD: testing equipment.

SUBSTANCE: invention can be used in preliminary and acceptance tests of weapons, military and special equipment (WMSE). Method of reproducing the action of high-duration air shock wave (ASV), which is refracted into water, on underwater engineering ammunition in open water reservoir conditions refers to testing equipment. Method includes installation of test object in water area, placement of concentrated charge of chemical explosive in air at some height above water surface at specified distance from test object and explosion of charge. Direct action on the test object of the refracted underwater shock wave (USW), which is formed during passage of ASV of increased duration over the water surface, is provided with a combination of action of dynamic and static pressure phases. Dynamic phase is formed by blasting explosive charge, for which mass of charge, height of its installation above surface of water and distance to UEM is set, based on the condition of the parameters of the refracted USW for parameters of the diffraction action on the UEM. Static phase is created by action of hydrostatic pressure, for this purpose test object is placed at depth providing required parameters of action.

EFFECT: technical result of the invention is to reduce the amount of chemical explosive required to reproduce the action of the extended-duration ASV on underwater engineering munitions (UEM).
