ABSTRACT:
The protection device according to the invention comprises a primary and a secondary coil facing each other. Current flow through the primary coil induces magnetic fields which repel each other, so that the two coils are jerked apart and a missile is projected towards an approaching projectile. The projecting device is triggered by a sensing device.
By offsetting the magnetic fields of the primary and secondary coil, the angle between the direction of acceleration of the missile and the coil plane may be changed, as required.
Preferably, the primary coil comprises several offset coil elements, which can be activated separately, in groups or all together, as desired.
