Note (General): This report introduces the experimental study on improving the catalytic ignition characteristics of green monopropellants for RCS thruster systems conducted at Nagaoka University of Technology. Our group focuses on two candidates for green monopropellants: HAN (Hydroxyl ammonium nitrate)-based SHP163 propellants and ADN (Ammonium dinitramide)-based AMU propellants. To improve the catalytic ignition characteristics of those propellants, some additive materials are tested. Acetone was added to SHP163 to improve its atomization characteristics, and hydrogen peroxide was added to AMU631 to improve its combustion efficiency. The injection test of acetone-adding SHP163 revealed how the ambient density and the saturation vapor pressure of the propellant affect the breakup mechanism of propellant flow from the injector. The thruster combustion test of hydrogen peroxide-adding AMU631 revealed the influence of additive material on the combustion characteristics and appropriate hydrogen peroxide additive ratio.
