DYNAMIC PROTECTION OF AN ARMORED OBJECT (OPTIONS) Russian patent published in 2022 - IPC F41H5/07 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment, in particular to the design of armor protection designed to counteract armor-piercing, sub-caliber and cumulative ammunition. The dynamic protection of an armored vehicle consists of upper and lower armor plates connected to each other at an angle of 90 degrees in the first version, which ensures the impact of kinetic energy on anti-tank ammunition. An element of dynamic protection can be placed on the upper plate in its front part, which will disperse the cumulative jet of anti-tank ammunition or partially reduce the energy of an armor-piercing or sub-caliber projectile. On the lower plate in its front part there is a protective comb, which is a triangular-shaped plate, in the lower part of which an insert is made, which is installed in the cavity located in the front part of the lower plate, where a powder sample is placed, which acts as a propellant charge. At the junction of the upper and lower plates, a hinged connection is made in the form of a loop welded to the main armor, and a rod passing through them, and a hole made at the junction of the upper and lower plates. This connection allows the movement of the bottom plate down until it touches the main armor plate and the joint rotation of the two plates until the top plate touches the main armor plate. This is achieved by a latch made at the junction of the rod and the hinge, which ensures free downward movement of the lower plate, but fixes the position of the upper and lower plates relative to each other when the upper plate moves towards the main armor plate. Elements of "dynamic" armor on the main armor sheet are placed sequentially one after another in such a way that the previous one covers the next one, leaving no unprotected sections of the main armor. The second version of the design provides for a fixed fixation of the upper plate and placement of a protective ridge on it. In this case, an insert is made in the lower part of the upper plate, which is installed in the cavity located in the front part of the plate, where a powder charge is placed, which acts as a propellant charge. The bottom plate in this embodiment is located directly on the main armor plate. On the upper and lower plates there are sensors that are triggered when the ammunition hits and sets fire to the powder charge of the previous element of dynamic protection. Elements of dynamic armor in this version on the main armor sheet are also placed sequentially one after another so that the previous one covers the next one, leaving no unprotected sections of the main armor. In this case, the angle between the upper and lower plates will depend on the inclination of the main armor plate.

EFFECT: increasing the protection of armored vehicles from the impact of heat, armor-piercing and sub-caliber projectiles by providing the most negative impact on the side surface of a HEAT armor-piercing projectile or the core of an armor-piercing sub-caliber projectile.
