DEVICE FOR FORMING THE NON-STATIONARY DECAYING SHOCK WAVE IN THE CONDENSED MEDIUM LAYER Russian patent published in 2018 - IPC G01M7/08 G01N3/313 

FIELD: physics.

SUBSTANCE: invention refers to the devices for studying shock-wave phenomena in condensed media and can be used in order to produce non-stationary decaying shock waves (Taylor waves) in the condensed medium (in particular, in water). Device consists of the impact tube including the explosive chamber and the accelerating channel that are coaxially docked with it, and cuvettes with the investigated condensed medium, located on the exit side of the accelerator channel coaxially and with the clearance relative to it. Striker is located in the acceleration channel with the possibility to move it under the action of products of the explosive process of the gas combustible mixture. Blasting chamber is made of two coaxial and adjacent compartments, which are separated from each other with the flat piston, the mass of which exceeds the mass of the striker. In the walls of the compartments of the blasting chamber, the gas lines are formed in order to connect to the source of the gas combustible mixture. Compartment of the blasting chamber, which is opposite to the accelerating channel, is equipped with means for initiating the explosive process of the gas combustible mixture, which is filled into this compartment. Piston is mounted with the possibility of its moving towards the striker and compressing the gas combustible mixture in the compartment adjacent to the accelerating channel, under the influence of the pressure of the explosive process products of the gas combustible mixture of the compartment, which is equipped with the initiating means.

EFFECT: ensuring the symmetry of the striker's flight during its acceleration in the accelerating channel by means of reducing the length of the accelerating channel without reducing the speed of the striker.
