Abstract

Die Erfindung betrifft eine Hochleistungswirkmasse (11) für pyrotechnische Infrarotscheinziele umfassend einen ersten Brennstoff, mindestens einen zweiten Brennstoff, ein Oxidationsmittel und ein Bindemittel, wobei der erste Brennstoff und das Oxidationsmittel hinsichtlich ihrer Redoxpotentiale so gewählt sind, dass das Oxidationsmittel den ersten Brennstoff nach Zündung in einer exothermen Reaktion unter Entstehung einer Primärflamme (12) und Emission von Infrarotstrahlung oxidieren kann, wobei der zweite Brennstoff bei der Reaktion entzündet, erhitzt und/oder pyrolysiert und aus der Hochleistungswirkmasse (11) freigesetzt wird, wobei der zweite Brennstoff so gewählt ist, dass dessen Redoxpotential oder das Redoxpotential mindestens eines Pyrolyseprodukts des zweiten Brennstoffs höher ist als das Redoxpotential des ersten Brennstoffs und dass der erhitzte oder entzündete zweite Brennstoff oder das Pyrolyseprodukt an der Luft brennen kann, wobei die Menge des in der Hochleistungswirkmasse (11) enthaltenen Oxidationsmittels höchstens so groß ist, dass sie gerade ausreicht, um den ersten Brennstoff vollständig zu oxidieren.

The invention relates to a high-performance active mass (11) for pyrotechnic infrared targets comprising a first fuel, at least one second fuel, an oxidizing agent and a binder, wherein the first fuel and the oxidizing agent are selected with respect to their redox potentials, that the oxidizing agent, the first fuel after ignition in an exothermic reaction with formation of a primary flame (12) and emission of infrared radiation can oxidize, wherein the second fuel is ignited in the reaction, heated and / or pyrolyzed and released from the high-performance active mass (11), wherein the second fuel is selected such that the redox potential or the redox potential of at least one pyrolysis product of the second fuel is higher than the redox potential of the first fuel, and the heated or ignited second fuel or pyrolysis product is capable of burning in the air, the amount of high power being high The maximum amount of oxidizing agent (11) contained so far is sufficient to completely oxidize the first fuel.
