LOCALIZING DEVICE FOR RESEARCHING FAST HYDRODYNAMIC PROCESSES Russian patent published in 2021 - IPC F42D5/04 G01N33/22 

FIELD: blasting technology.

SUBSTANCE: invention relates to the field of blasting technology and the study of fast hydrodynamic processes, in particular to devices that ensure the safety of experiments under intense dynamic (explosive) loads created by loading devices using explosives, for example, when conducting a study of shock-induced "dusting" - ejection of particles when the shock wave reaches the free surface of the sample. The device for studying fast hydrodynamic processes contains an external sealed chamber, in which an explosion-proof chamber is placed to accommodate the object under study and a loading device, including an indestructible reinforced body, a cover and a bottom. In the reinforced housing, at least one pair of diametrically opposite holes and corresponding holes is made in the housing of the external sealed chamber for the formation of inputs, all openings are closed with plugs transparent for optical and radiographic radiation, and the explosion-proof chamber (EPC) is equipped with pressurized junctions for installing sensors for recording the parameters of physical processes. A capsule is placed in the cavity of the EPC to accommodate the object under study, which has at least one pair of diametrically opposite inputs formed by the corresponding holes in it, and plugs transparent for optical and radiographic radiation, coaxial with the corresponding inputs on the EPC and an external sealed chamber. The lid, bottom and caps of the capsule are made with the possibility of destruction when the object under study is loaded. The loading device is installed on the capsule lid and around it there is a gas-dynamic reflector in the form of a conical shell, fastened to the reinforced housing of the EPC and installed by expanding towards its indestructible cover, the bottoms of the EPC are also indestructible, of equal strength with a reinforced housing and remote from the loading device at a distance of at least one diameter of the EPC body.

EFFECT: technical result of the claimed invention is to increase the explosion resistance of the structure, which makes it possible to increase the environmental, radiation and explosion safety of the experiments. An additional technical result is the expansion of the functional capabilities of the device due to changes in the design and its dimensions, which make it possible to expand the range of research objects, increase the number of sensors, apply techniques based on different physical principles, which also makes it possible to increase reliability and statistics of measurement results in a wide range of dynamic (explosive) loads.
