Atmospheric Pressure Studies of Liquid Propellant Drops in Hot Flows.

Abstract

Single drops of 13 M aqueous Hydroxyl Ammonium Nitrate (HAN) and a liquid monopropellant (LP 1845) have been studied in hot flows from 700 to 950 C at ambient pressure. Measurements of drop diameter rate behavior show no effect of oxidizer presence and little temperature dependence. This report includes the first known observations of microexplosions of these liquid monopropellants. Drops are seen to explode from internal pressure after typically 25% of the volume has been consumed. These explosions do not appear to consume a substantial portion of the drop material, but they do result in the formation of many small drops, and hence, greatly increased surface areas. Arguments are presented that this effect is due to superheating of the water component.
