METHOD OF MAGNETOIMPULSE EXPANSION OF CONDUCTIVE SHELLS AND DEVICE FOR ITS ACCOMPLISHMENT Russian patent published in 1996 - IPC

FIELD: magnetoimpulse working of materials, in particular, at utilization (unloading) of ammunition. SUBSTANCE: magnetic field, first growing to magnetic induction B ≥ Bo, then quickly vanishing during time period t_s, is induced on the shell external surface. The device uses solenoid (induction coil) 4 with cavity 3 used to accommodate housing 1 with explosive 2. The solenoid is connected to capacitor 5 via switch 6 and quick-acting (for example, explosive) release 7. EFFECT: facilitated procedure. 3 cl, 1 dwg
