CONTACT EXPLOSIVE APPARATUS FOR PENETRATING AMMUNITION Russian patent published in 2022 - IPC F42C11/06 F42C1/12 

FIELD: explosives.

SUBSTANCE: invention relates to military equipment, namely, to contact explosive apparatus for penetrating ammunition, wherein the warhead is detonated upon a predetermined deceleration time on impact with the obstacle, can be used to ensure the optimal mode of initiation of the ammunition on impact with a particularly strong or impenetrable obstacle. Contact explosive apparatus for penetrating ammunition comprises a contact sensor system and a safety and arming mechanism. The contact sensor system is installed on the front surface of the warhead, and a critical condition unit is installed in the bottom area of the warhead, including a vibration sensor, a pulse former, an RS trigger, a time-voltage converter, a voltage divider, a sawtooth voltage generator, a switch, and a comparator. The output of the contact sensor system is connected to the input of the delayed action circuit of the safety and arming mechanism and to the S input of the RS trigger. The vibration sensor is connected to the input of the pulse former, the output whereof is connected with the R input of the RS trigger, the control input of the switch, and the launch input of the sawtooth voltage generator. The output of the sawtooth voltage generator is connected with the analogue input of the switch, wherein the inverting input of the comparator is connected to the output of the switch, the non-inverting input of the comparator is connected to the output of the voltage divider, and the output of the comparator is connected to the input of the instant action circuit of the safety and arming mechanism.

EFFECT: increase in the operating effectiveness of penetrating ammunition and allows for instant detonation of penetrating ammunition in conditions of controlled destruction of the body of the warhead on impact with a particularly strong or impenetrable barrier.
