A method for production of an infrared area emitter which can be used for defense against guided missiles with infrared homing heads, for example for ships. According to the invention, an aerosol cloud which is emissive in the infrared range is produced by the reaction of a first primary aerosol composed of an aqueous solution of an electron acceptor with a second primary aerosol composed of an aqueous solution of an electron donor in order to produce the infrared area emitter. The use of primary aerosols such as these leads to emission at 3-5 and 8-14 &#x3bc;m, and does not produce any visual signature either.

Method and apparatus for production of an infrared area emitter

An energy-producing material which comprises a chemically uniform polymer material whose monomer units contain an electron donor and an electron acceptor, wherein the stoichiometric ratio of electron donor to electron acceptor is &#x2266;1, is proposed.

Energy-producing material

A highly energy-producing compound which can be used, for example, as an explosive, propellant, oxidant and the like, and which includes an alkyne unit in which at least one hydrogen atom has been replaced by a trinitromethyl-C(NO)group.

Highly energy-producing compound

A pyrotechnic charge for producing IR radiation is proposed, in which a deuterated compound is contained as fuel and/or as oxidizing agent or as fuel, as oxidizing agent and/or as binder. The use of such a pyrotechnic charge leads to a greater selective radiant emission in the &#x3b2;-band and at the same time to a reduced selective radiant emission in the &#x3b1;-band, so that the signature of a decoy is adapted to that of an aircraft.

Pyrotechnic charge

An infrared decoy flare composition for generating infrared radiation, including a fuel, an oxidizing agent and a binder, wherein the decoy flare composition contains no metals or metal-containing compounds and no halogens or halogen-containing compounds. Such an infrared decoy flare composition can be particularly advantageously used in aerial infrared decoy flares for civil aircraft.

A device for firing energetic materials ( ) such as pyrotechnics or explosives, including a firing composition ( ) for the energetic materials ( ) and an UV-radiation source ( ) for irradiating the firing composition ( ), wherein the UV-radiation source ( ) possesses a piezo-luminescence element ( ) in order to provide a current-less and electromagnetically interference-secure firing device.

Device for firing energetic materials such as pyrotechnics or explosives

A pyrotechnic active material for producing IR-radiation is proposed. An active material according to the invention contains fuel (preferably magnesium) which combines with fluorine in a strongly exergonic reaction (for example Li, Be, Mg, Ca, Sr, Ba, Ti, Zr, Hf, B, Al and alloys thereof) and poly-(carbon monofluoride) ((&mdash;CF &mdash;)n) (x&equals;0.6-1.2) as an oxidation agent. Compositions according to the invention further contain VITON&reg; as a polymeric binding agent and graphite for reduction of the electrostatic sensitivity. A process for producing those compositions is also provided.

Pyrotechnic composition for producing IR-radiation

The invention relates to a pyrotechnic active mass which is impenetrable in the visible spectrum, highly emissive in the infrared spectrum and used for camouflage and decoy purposes. As principal ingredients said mass contains red phosphorus and an alkali metal nitrate or mixture of alkali metal nitrates and as secondary ingredients at least one transition metal or a metal-rich compound or alloy thereof, at least one metalloid and a binder.

The invention relates to a pyrotechnic smoke screen unit for producing an aerosol which is impenetrable in the visible, infrared and millimetric wave range and used for camouflage and decoy purposes. The units are obtained by combining fibre-like conductive dipoles or dipole precursors which become conductive in situ and conventional pyrotechnic smoke substances active in the visible and infrared range.

The invention relates to a method of producing a screening smoke which is one-way transparent in the infrared spectrum (780 nm-14.0 &mgr;m) and opaque in the visible spectrum. According to the invention a known pyrotechnic screening smoke which is highly absorbent in the visible spectrum (380 nm-780 nm) is generated in the form of an aerosol, pyrotechnic scattered particles between 10 and 100 &mgr;m in size are simultaneously produced in said aerosol, and the resulting two-component smoke is irradiated by an infrared radiation source (spectrum: 780 nm-14.0 &mgr;m) from the smoke producer side.

Method of producing a screening smoke with one-way transparency in the infrared spectrum

The invention relates to an electronically and mechanically-operated ignition delay which is used in cartridge-type pyrotechnic decoy flare ammunition. Said ignition delay comprises a cylindrical sleeve ( ), containing an ignition device ( ) in the base, a propellant ( ) for expelling the inflammable active material ( ) and devices ( ) for delaying the ignition of the active material. The electric ignition device of the propellant charge is galvanically connected to a capacitor element ( ) which is fixed in the propulsion reflector ( ). Said capacitor element is galvanically connected to a mechanical switch-on element ( ) in the active material, whereby said mechanical switch-on element is, in turn, galvanically connected to an electric ignition unit in the active material. The switch-on process is thus triggered by the relative movement of the active material as it travels along the sleeve axis away from the propulsion reflector.
