ABSTRACT:
In a protection arrangement for affording protection from projectiles (13) attacking armoured vehicles (11) such as in particular combat tanks catapult-type plate modules (18) are no longer carried directly by the structure of the vehicle (11) to be protected but by a front mounting (17) which is of comparatively lightweight structure but which is rigid in respect of deformation by virtue of strut structure means of a three-dimensional framework-like configuration and which in particular is mounted in front of the front (16) of a combat tank body (12) but which can also be provided therearound. Upon triggering of a module (18) by a sensor (22) which is fixed with respect to the vehicle and which extrapolates the current attack trajectory (23) two plates (19) which are oriented in mutually parallel relationship are flung away in mutually opposite directions by the acceleration device (20) which is arranged centrally between the plates and which is for example electromagnetic or preferably pyrotechnic, so that the load-bearing front mounting (17) has to carry practically no acceleration reaction forces. One of the two plates (19) which are oriented approximately parallel to the attack trajectory (23) and which are accelerated transversely thereto hits the approaching projectile (13) laterally in the front region and thereby alters the angle of incidence, with a reduction in kinetic energy or triggering of the warhead, so that even impact against the vehicle (11) no longer results in penetration.
