METHOD FOR DETERMINING ENERGY CHARACTERISTICS OF TEST OBJECT Russian patent published in 2019 - IPC F42B35/00 G01N33/22 

FIELD: test equipment.

SUBSTANCE: invention relates to the field of testing and measuring equipment, and in particular to methods for determining the energy characteristics of ammunition and explosive charges. Method includes placing the test object on the test site, at a predetermined distance from the recording device, the position and size of which is determined during the implementation of the preliminary image. Control reference mark is arranged in close proximity to the test object. As a registering device, a high-speed video recorder with a time synchronization device with undermining the test object is used. Front of the air shock wave is recorded in the slit linear sweep mode and the subsequent processing of the received images is performed along the front of the air shock wave, then, the dependences of the shock front movement on time are compiled and the parameters of speed, maximum overpressure of the air shock wave and the trotyl equivalent are determined. As a recording device, it is possible to use a digital electron-optical camera or a high-speed photo recorder. As a reference mark the reference scale object is used.

EFFECT: method allows to increase the accuracy of determining the energy characteristics of the test object.
