METHOD FOR INCREASING ARMORED RESISTANCE OF ARMORED PROTECTION ELEMENTS Russian patent published in 2023 - IPC F41H1/02 

FIELD: armour engineering.

SUBSTANCE: to increase the impact strength of the armour protection elements (1), their dynamic load arising from contact with the bullet/shrapnel (2) is reduced by means of a sensor (3) fixed on the armour protection elements (1), configured to convert the shock pulse from the bullet/shrapnel (2) contact with an armour protection element (1) into an analog signal of the vibrator (4). The sensor (3) fixes the shock pulse after the contact of the bullet/shrapnel (2) with the armour protection element (1). The shock pulse in the form of an analog signal is sent to the board (5) input. Inside the board (5), the analog signal is converted to digital and processed by the built-in microcontroller with the ability to determine the time of the shock pulse, the frequency of the disturbing load, and the frequency of natural oscillations of the armour protection element (1), depending on the frequency of the disturbing effect of the bullet/shrapnel (2). At the output of the board (5), a pulse-width control signal is formed, which is amplified by a transistor (7), with the possibility of ensuring the operation of the vibrator (4). The vibrator (4) converts the electrical signal into mechanical vibrations, which are transmitted to the armour protection element (1) interacting with the bullet/shrapnel (2) with a disturbing frequency of a greater frequency of the natural oscillations of the armour protection element (1).

EFFECT: higher impact strength is ensured with unchanged or smaller weight and size and worse strength parameters of the armour protection element.
