Combustion Mechanisms of HAN-based Green Monopropellants
Abstract
The objective of the proposed research is to understand and predict combustion mechanisms of hydroxylammonium nitrate as a function of pressure, in order to replace toxic hydrazine with green monopropellants in space propulsion systems. The objectives include the determination of the burning rates and clarification of the combustion regimes of HAN- ethanol propellants, with and without nanoscale additives, over the pressure range from 0.1 to 34.5 MPa. Hydroxylammonium nitrate based propellant are attractive due to their low toxicity, high density, high specific impulse, and low freezing point.
