DEVICE FOR DETECTING CONDITION, SYMMETRY AND DYNAMICS OF LINERS MOVEMENT IN GASEOUS MEDIUM Russian patent published in 2019 - IPC B01J3/08 

FIELD: physics.

SUBSTANCE: invention can be used for investigation of quasi-isentropic compressibility of gases in megabar pressure range. Essence of the invention is that the device comprises a hemispherical explosive charge placed on the base, in the cavity of which the hemispherical spacer from the material with low dynamic impedance and the first steel liner are axially symmetrically installed, electric-contact sensors arranged on one of the boundaries of the first liner, a measuring receiver with sensors-collimators installed symmetrically about the axis of the device according to the heterodyne-interferometer circuit, is equipped with a second axisymmetrically installed in the cavity of the first liner, hemispherical steel liner with holes, electric contact sensors are additionally installed on the outer boundary of the spacer, the steel base is solid, on its surface under the second liner symmetrically relative to the device axis is tightly fixed with a convexity hemispherical optical window of quartz glass is formed in the base with formation of a sealed cavity intended for gas inlet under it under high initial pressure, at that sensors of the measuring receiver are installed in the base along the normal to the surface of the window tightly to it.

EFFECT: technical result is possibility of obtaining in one experiment the entire set of data required for calibrating gas-dynamic calculations.
