Abstract:
A pyrotechnic smoke screen unit for the production of an aerosol for camouflage and decoy purposes impenetrable in visible, infrared and millimetric wave ranges comprising pre-produced dipoles selected from the group consisting of fiber-formed conductive dipoles and dipole precursors which become conductive in situ, wherein the dipoles consist of thin, conductive fibers of metal, graphite or of glass, ceramic or synthetic material fibers which are provided with a conductive coating of metal and have a length of 1 to 30 mm and a diameter of 0.001 to 0.1 mm, wherein the fibers are coated with a first layer of phosphorus or phosphorus sulfide and a second ignition layer of a combustible material, an oxidation agent and a binding agent, whereby these layers have thicknesses of 0.001 to 0.1 mm, wherein the pre-produced dipoles correspond to electromagnetic radiation in the millimetric wave region of the frequency bands for the targeting apparatus, wherein pyrotechnic smoke screen unit contains 5 to 25% of fiber-formed conductive dipoles or dipole precursors which become conductive in situ.
