STAND FOR REVERSE THROWING OF REINFORCED CONCRETE PLATES ON AMMUNITION Russian patent published in 2025 - IPC F42B35/00 

FIELD: testing; ammunition.

SUBSTANCE: invention relates to test benches of penetrating ammunition. Penetrating ammunition test bench comprises fixed ammunition with actuation delay. Axis of the ammunition is perpendicular to the thrown plate; the device for throwing the plate is made in a destructible housing with limiters of the distribution of explosion products, which is filled with an explosive. Housing wall between explosive and thrown plate is made of inert damping material. Structure is elevated above the ground to a height which ensures the flight of the plate without touching the ground at the length from the initial position to the end of the ammunition, contains recording video or film cameras, contact sensors. Thrown plate is made of concrete or reinforced concrete, lined with steel sheets connected to each other at joints, in steel sheets facing ammunition and throwing device, there are through holes with diameter exceeding that of ammunition. Centres of through holes in the plates coincide with the axis of the ammunition at the moment of interaction of the plate with the ammunition, the hole facing the throwing device is closed with a steel sheet with a diameter greater than or equal to the diameter of the through hole, and connected to the lining sheet of the thrown plate by welding, which is destroyed during interaction of the thrown plate with ammunition.

EFFECT: development of a stand providing safe throwing of reinforced concrete plates during testing in static conditions of the landfill, obtaining experimental data and storing registration results on the state of the hull, and confirming operability.
