Closed chamber tests on hydroxylammonium nitrate (HAN) based liquid monopropellants (LPs) were performed at loading densities of about 0.2 g/cm 3 at both the Fraunhofer‐Institut für Kurzzeitdynamik (EMI‐AFB), and the Ballistic Research Laboratory (BRL). The objective of the studies was to investigate the decomposition of the HAN based liquid propellants under various conditions. Pressure and temperatures were measured for both neat and intentionally contaminated monopropellants. Contaminants tested were iron, copper, aluminum, and nickel at concentrations of about 100 ppm. The temperatures were determined using both thermocouples and specially designed temperature (emission) gages. The data illustrate the behavior of the liquid propellants during the decomposition phase.
