| Summary: | Research and development of Hydroxyl Ammonium Nitrate based liquid propellant; SHP-163 is reviewed. Starting from the composition selection of the propellant to the development of 1 N thruster of Green Propellant Reaction Control System (GPRCS) project and the successful demonstration test in space is summarized. Combustion behaviors of SHP-163 were investigated and the mechanism of the very high burning rate at high pressures was studied. The observation on HAN-aqueous solutions revealed that the apparent very high burning rate is triggered by hydrodynamic instability and controlled by water nuclei formation rate which is induced by the superheat by the exothermic reaction of HAN decomposition. The operation pressure of GPRCS was determined considering this high burning rate region. Other characteristics of SHP-163 are also presented. |
