METHOD OF DETERMINING REACTED EXPLOSIVE CHARGE MASS Russian patent published in 2020 - IPC F42B35/00 

FIELD: measurement.

SUBSTANCE: invention relates to measurement of characteristics of explosion of ammunition or explosive substance charge (ES). Method of determining reacted explosive charge (ES) mass includes recording of air shock wave (ASW) from air or ground explosion of ES unknown mass charge and determining at least one value of the ASW front radius at a given moment in time with respect to explosion of the ES charge, is characterized by the fact that immediately before blasting of the unknown mass ES charge, recording the ambient temperature and pressure value, ASW is recorded using a high-speed video camera, wherein at least one ASW image is obtained at a given moment in time with respect to ES explosion of unknown mass, ASW image is used to determine the ASW front radius value, and the reacted ES charge mass is determined based on the obtained data comparison with the experimental or design relationship, describing change in time of ASW front radius value at ES specified mass blowing with preset mass at preset values of ambient temperature and pressure, note here that blasting type corresponds to explosive ES charge of unknown mass.

EFFECT: high accuracy of determining the reacted mass of the ES charge.
