METHOD FOR MULTIPLE CONTACTLESS INSTALLATION AND COUNTING OF TIME OF ACTION OF REMOTE FUSE Russian patent published in 2022 - IPC F42C13/00 

FIELD: military technology.

SUBSTANCE: invention relates to the field of military technology, and more correctly to electronic remote fuses with a contactless remote method for entering a combat mission - programming, and can be used to count the time of remote action of fuses of artillery and rockets, bombs and other ammunition, to count the time of long-range cocking and self-destruction. The invention can be used to form a combat mission to detonate ammunition, separate the warhead, deploy a cluster warhead, eject a parachute system. The method for non-contact setting and counting the time of action of a remote fuse includes the formation by the installer of information signals that determine the required time of action of the fuse, with a constant value of the time interval between the elements of a code consisting of several parts. The first part of the code contains information about the numerical value of the action time code, and its subsequent parts contain information about the duration codes of additional times. Information signals are transmitted in a continuous sequence of information signals that program the munition for the range of detonation by the n-th packet of programming pulses from the sequence of N possible ones emitted by the transmitter. The formation of information signals by the installer is carried out taking into account the guard interval Ts, which is mandatory to ensure the safety of the firing position. Information signals are formed taking into account the time interval of arrival of the next n+1 pulse, during which the ammunition passes the distance X_n+1-X_n, proportional to the previous programming interval T_n.

EFFECT: high accuracy of counting the set action time and the possibility of increasing the information entered into the fuse.
