APPARATUS FOR RECORDING DYNAMICS AND CONDITION OF IMPACT-LOADED SPHERICAL LINER SURFACE Russian patent published in 2021 - IPC B01J3/08 G01N33/22 G01N25/50 

FIELD: measuring.

SUBSTANCE: invention relates to the field of measuring equipment, namely to registration of parameters of the dynamics of impact-induced "dusting" from the inner surface of a spherical liner during assessment of the state/behaviour thereof under load. The apparatus for recording the dynamics of the condition of an impact-loaded spherical liner surface includes a hemispherical charge of an explosive substance (ES) placed on the base and sensors recording the movement of the liner installed in the charge cavity and configured to form a sealed volume connected with the gas inlet system. The liner is installed adjacent to the charge of the ES. A sealed volume is formed between the liner and a hemispherical bracket fixed on the base with a curvature facing the liner. The gas inlet system is connected with a pump to create underpressure. Additionally, sensors based on different physical principles are installed to measure the speed, density distribution and mass of the dust flow escaping from the liner surface, namely collimators, piezoelectric sensors, collimators with indicator screens, fixed on the bracket and placed in a sealed volume at different distances from the liner surface.

EFFECT: increased information content of the experimental results is provided by directly determining the quantitative characteristics of the process of impact-induced "dusting".
