METHOD OF CORRECTING THE TIME OF OPERATION OF A REMOTE DETONATING FUSE OF AN ARTILLERY SHELL Russian patent published in 2019 - IPC F42C9/00 F42C13/08 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to munitions of barrel artillery and can be used in fuses of artillery shells. Method of correcting actuation time of fuse of artillery projectile firing on hinged trajectory, which consists in the fact that before firing, calculation is used to determine time of remote detonating fuse T_p and time, for which projectile under given shooting conditions reaches maximum height T_mmax. Using the hardware, the value of these times is entered into the remote fuse computing device, and a shot is fired. Remote fuse is equipped with a device for determining time for projectile reaching maximum height T_mi. Actual actuation time of remote fuse T_pi shell is determined from the following ratio: T_pi=T_p+(T_mmax-T_mi), where T_pi – actual operation time of remote fuse, T_p – design time of remote device actuation, T_mmax is maximum design time of shell reaching maximum height at specified firing conditions, T_mi is the measured actual time before shell reaches maximum height. In order to determine time of projectile reaching maximum height continuously during projectile flight, difference of readings is measured from two Hall sensors located 180° on the surface of the remote fuse with the working planes parallel to the projectile axis and connected in opposition, and for moment of time corresponding to maximum flight height of projectile T_mi, time corresponding to maximum difference is selected.

EFFECT: disclosed is a method of correcting the actuation time of a remote detonating fuse of an artillery shell when firing on a hinged trajectory.
