MULTIMODE FUSE Russian patent published in 2024 - IPC F42C13/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition fuses, namely to multimode fuse. Multimode ammunition fuse contains installed in the housing a control unit, a power supply unit, a protection system with a combat mission interruption system, long-range arming mechanism, self-destruction system, contact sensor, operational safety system, safety-actuating mechanism and electronic switches. Control unit is based on a programmable microcontroller. Operational safety system includes a screw, a pin and a locking contactor. Fuse additionally contains a non-contact optical signal sensor, which includes an emitter, a current amplifier and a photodetector, as well as a unit of capacitors. Photodetector of the proximity sensor is connected to the first input of the microcontroller-based control unit, and the emitter is connected through a current amplifier to the first output of the microcontroller-based control unit. Power supply unit is self-contained and contains a power supply element, a first electronic switch and a DC/DC voltage converter, in which the power supply element is connected to the second input of the control unit based on the microcontroller, and the positive pole is connected to the interlocking contactor of the operational safety system connected to the third input of the control unit based on the microcontroller. Safety-actuating mechanism includes an electric igniter and an electric detonator shunted with a jumper, as well as connected to a control unit based on a microcontroller through the second and third electronic switches, respectively. First electronic switch is connected to the second output of the control unit on the basis of the microcontroller, providing connection of the power supply element to the DC/DC voltage converter connected to the unit of capacitors connected to the second and third electronic switches. Second electronic switch is connected to the third output of the control unit on the basis of the microcontroller, providing the electric igniter actuation. Third electronic switch is connected to the fourth output of the microcontroller-based control unit and connects the capacitor unit with the electric detonator. One output of the contact sensor is connected to the negative bus of the power supply element, and the other output is connected to the fourth input of the control unit.

EFFECT: enlarging functional capabilities of fuse, improving efficiency of hitting targets, improving safety of operation of ammunition equipped with fuse, possibility of using fuse in ammunition used on UAV.
