DEVICE TO FIT PROJECTILE FUSE IN PLACE Russian patent published in 2009 - IPC F42C17/00 

FIELD: weapons and ammunition.

SUBSTANCE: device comprises a magnetic field source and receiving induction coil fitted inside the fuse, the said source and coil are coaxial to the gun barrel and designed to input, during the shot, the power and data on spatial position of projectile relative to the gun barrel axis. To increase accuracy of fitting the fuse in place and operating reliability, the device incorporates an additional magnetic field source mounted along the gun barrel at a distance from the main magnetic field source, and a computation unit wired in the fuse. Note here that aforesaid magnetic field sources represent two similar-pole-coupled circular permanent magnets with lengthwise magnetisation, the receiving induction coil core is connected with the computation unit, while the induction coil is furnished with ferromagnetic flanges mating the projectile inner shape. The device can incorporate magnetic circuits to be mounted on faces of aforesaid permanent magnets, the said magnetic circuits representing washers abutting on the gun barrel outer surface, and damping gaskets to allow the permanent magnets to be mounted on the gun barrel.

EFFECT: higher accuracy of mounting and operating reliability of fuse.
