DEVICE FOR CONTAINMENT OF EXPLOSION PRODUCTS ACCOMPANYING STRIKER Russian patent published in 2024 - IPC F42D5/45 F41H5/04 F42B35/00 

FIELD: testing.

SUBSTANCE: invention relates to testing equipment and is intended for protection of objects from explosion products during tests, in which for throwing strikers made in the form of plates, explosive charges are blasted. Device for containment of explosion products accompanying the striker, made in the form of a plate, contains blast product scatterers made in the form of plates with coaxial holes for the striker passage installed in series perpendicular to the trajectory of the striker with gaps relative to each other. Dimensions of gaps d between scatterers are not equal to each other and are taken from the range d=(1-8)h, where h is striker thickness. Acoustic stiffness of the material of the diffusers is greater than or equal to the acoustic stiffness of the material of the striker.

EFFECT: redistribution of pressure in explosion products due to their successive deceleration and dispersion, as a result of which the speed of propagation of explosion products accompanying the striker is reduced to the speed of the striker; providing optical recording of the profile of the front surface of the striker from its initial position, during passage of the scatterers and after leaving them, as well as the possibility of interaction of the periphery of the moving striker with the edges of the holes made in the plates.
