DEVICE FOR MEASURING VELOCITY ON MUZZLE OF GUN Russian patent published in 2025 - IPC F41A21/32 

FIELD: measuring.

SUBSTANCE: device for measuring velocity on the muzzle of a gun comprises a magnetic field generator mounted on the barrel at the muzzle of a gun and made on the basis of a permanent magnet, a magnetic detector in the form of an inductance coil and a backup system for measuring velocity of the projectile; a magnetic belt is installed on the projectile for interaction with the backup system. Projectile comprises main system, which includes high-speed comparator, inverter, microcontroller with memory, magnetic detector. Magnetic field generator is made either in the form of two permanent magnet belts, or two inductance coils, through which direct current passes, wherein width b₁ and height h₁ of these permanent magnet belts or width b₂ and height h₂ of winding of inductance coils, as well as width b₃ and height h₃ of winding of inductance coil, which is a magnetic detector, are selected from the following condition: b_i/h_i<1.

EFFECT: high accuracy of measuring projectile speed on the muzzle of a gun and high noise immunity.
