Abstract: A method suitable for protecting targets against attacking projectiles as rockets consist in producing an infrared jamming radiator which radiator jams the infrared target finder of the attacking projectile. The jamming radiator is produced in the vicinity of the target and may be embodied by a jammer cloud consisting of burning particles, preferably foil strips, emitting an infrared radiation more intensive than the infrared radiation of the target and staying sufficiently long in the air as to divert the rocket from the target. The strips are stowed in a container which is emitted from the target and distributes the ignited strips into the airspace near the target.

Abstract: A smoke cup projectile charge comprising smoke cups stacked one above the other in the shell jacket in discharging direction, the smoke cup supporting components having identical strength and being filled with smoke charge composition comprising hexachloroethane, zinc oxide and metal powder, and a fuse system of priming cartridges embedded in transmission composition in the smoke charge and ignited by capillary delay tubes.

Abstract: A pyrotechnic smoke charge which comprises guanidinium nitrate and (a) chlorohydrocarbons and a metal powder, of (b) red phosphorous, which can be partially replaced by a chlorohydrocarbon, and wherein said charge may optionally contain a small amount of a reaction regulating agent.
