UNIVERSAL ELECTRONIC FUSE FOR SMALL-CALIBER AMMUNITION Russian patent published in 2022 - IPC F42C9/00 G01P3/48 

FIELD: military equipment.

SUBSTANCE: invention relates to the field of military equipment; it can be used as a multi-mode electronic fuse of small-caliber artillery ammunition. A multimode electronic fuse for small-caliber artillery cartridges contains a detonator, a safety cocking device, a power source, an electronic module containing an arithmetic logic unit (ALU), operational and permanent storage devices for storing variable constants and constant coefficients, a clock generator, a real-time timer, an initial initialization circuit of an electronic device and a linear acceleration sensor, and it is characterized in that, that the clock generator is made in the form of an RC generator with temperature compensation for receiving data from equipment connected to a gun, the fuse contains: a polarized UHF radio frequency antenna, and the electronic fuse module contains an UHF receiver, at an output of which a detected signal amplifier and a radio channel interface controller detecting and decoding input radio channel commands are sequentially switched on; or an IR photodetector, and a photodetector signal amplifier and an optical channel interface controller detecting and decoding input optical channel commands are sequentially inserted into an electronic part of the fuse; or an induction communication coil, and an amplifier-demodulator of inductive communication channel signals and an inductive channel interface controller detecting and decoding input inductive channel commands are introduced into the electronic part of the fuse.

EFFECT: possibility is provided to initialize projectiles and set its operating modes in several ways: using a radio channel, an optical channel or an induction channel, both before and after the shot; possibility is provided to calibrate individual components of the electronic part of the fuse, for example, the built-in clock, directly during the shot, which allow for an increase in the efficiency of the combat use of ammunition due to reduction in the dispersion of the point of detonation of projectiles on the flight path.
