Abstract

The thermolysis of ammonium perchlorate (AP) and AP/polystyrene propellants was investigated with carboxylates of copper as additives. The rate of burning was found to be enhanced considerably. TG and ignition delay studies demonstrated that the high-temperature decomposition of AP is enhanced enormously by these additives, whereas the low-temperature decomposition remains unaffected. It is suggested that the main species catalysing the rate of burning or AP decomposition is CuO. Analysis showed that the increase in the rate of burning is controlled by the catalysis of AP decomposition.

Zusammenfassung

Unter Zusatz von Kupfercarboxylaten wurde die Thermolyse von Ammoniumperchlorat- (AP) und AP/Polystyrol-Treibstoffen untersucht. Die Brenngeschwindigkeit wird erheblich erhöht. TG- und Zündverzugsuntersuchungen zeigen, daß die Zersetzung von AP durch Zusatz dieser Additive bei hohen Temperaturen enorm ansteigt, während sie bei niederen Temperaturen unverändert bleibt. Es wird darauf hingedeutet, daß die wichtigste Komponente zur Katalyse des Brennvorganges bzw. der Zersetzung von AP das Kupferoxid CuO ist. Eine Untersuchung zeigte, daß der Anstieg der Brenngeschwindigkeit durch die Katalyse der Zersetzung von AP bestimmt wird.
