Pyrotechnic charge
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 β-band and at the same time to a reduced selective radiant emission in the α-band, so that the signature of a decoy is adapted to that of an aircraft.
