METHOD FOR OPAQUING VISIBLE AND INFRARED RADIANCE AND SMOKE-PRODUCING AMMUNITION WHICH IMPLEMENTS THIS METHOD

Abstract

The invention concerns a method and a smoke-producing pyrotechnical ammunition to shield the visible and infrared radiance in a wave length included between 0.4 and 14 μm emitted by a target. First we produce instantly a first hot aerosol with a fast pyrotechnical composition, which masks the target through diffusion in the visible spectrum and with its emitting potential in the infrared zone. Then, we produce a second aerosol which contains hot carbon particles of which the size is included between 1 and 14 μm with a slow pyrotechnical composition for shielding mainly through diffraction the thermal image emitted by the target. The fast composition includes zinc and zinc oxide, potassium perchlorate, hexachlorobenzene or hexachloroethane powder and a binding agent. The slow composition includes a compound which generates carbon particles of 1 to 14 μm such as hexachlorobenzene hexachloroethane, naphtalene, anthracene, a reducing agent like a metal powder (magnesium) and an oxidizer like hexachlorobenzene and/or hexachloroethane.
