Abstract

Die Erfindung betrifft eine pyrotechnische Scheinzielwirkmasse umfassend erste Partikel, die einen ersten Brennstoff umfassen, zweite Partikel, die den ersten oder einen zweiten Brennstoff umfassen, ein Oxidationsmittel für den ersten Brennstoff und ein Bindemittel, wobei der erste Brennstoff mindestens ein Metall ist, wobei der zweite Brennstoff mindestens ein Metall ist oder die zweiten Partikel ausschließlich aus dem zweiten Brennstoff bestehen, wobei der erste Brennstoff und das Oxidationsmittel nach Zündung in einer exothermen Reaktion unter Freisetzung von Infrarotstrahlung miteinander reagieren können, wobei die zweiten Partikel durch die Reaktion entzündet und aus der Scheinzielwirkmasse freigesetzt werden. Dabei sind die ersten Partikel kleiner als die zweiten Partikel oder auf sonstige Weise so beschaffen, dass sie nach einer Zündung der Scheinzielwirkmasse an Luft schneller verbrennen als die zweiten Partikel, wobei die zweiten Partikel so beschaffen sind, dass sie für mindestens 10 ms an der Luft brennen.The invention relates to a pyrotechnic sham targeting composition comprising first particles comprising a first fuel, second particles comprising the first or a second fuel, an oxidant for the first fuel and a binder, wherein the first fuel is at least one metal, the second Fuel is at least one metal or the second particles consist exclusively of the second fuel, wherein the first fuel and the oxidizing agent after ignition in an exothermic reaction with release of infrared radiation can react with each other, the second particles are ignited by the reaction and released from the sham targeting mass become. In this case, the first particles are smaller than the second particles or otherwise designed so that they burn faster after ignition of the fictitious target in air than the second particles, the second particles are such that they are for at least 10 ms in the air burn.
