ELECTROMAGNETIC ACCELERATOR WITH PROJECTILE SPINNING Russian patent published in 2005 - IPC

FIELD: armament, in particular, electromagnetic launchers.

SUBSTANCE: the solenoid-type multiple-stage linear electromagnetic accelerator has a ferromagnetic projectile, cylindrical non-magnetic barrel with coaxially fastened on it traction solenoids having outer magnetic cores and means of switching of the supply circuits by the signals of the projectile position pickups. The cylindrical projectile has cavities in the form of longitudinal channel, the inner holes in the magnetic cores are made with recesses located opposite the depressions in the projectile, the recesses in the magnetic cores of the adjacent coils are positioned with a relative angular shift in several degrees.

EFFECT: stabilized spinning of the projectile with a linear acceleration.
