“…One such example, Space Solutions Co., Ltd., South Korea, is commercializing a green propulsion system based on hydrogen peroxide and ADN-based monopropellant systems. We successfully tested a 50 N hydrogen peroxide green monopropellant propulsion system for the altitude control system of the three-stage Korean Space Launch Vehicle (KSLV) during model flight launches [19]. Although hydrogen peroxide is a good option for latecomers to space technology who find it difficult to use hydrazine, it has issues with storage stability and requires passivation for aerospace components.…”

The development of propulsion systems based on green propellants, as an alternative to hydrazines, has been gaining interest within the space community. The study of Ammonium Dinitramide (ADN)-based liquid monopropellant, which is low-toxic and can deliver high performance, is the focal point of interest for Space Solutions Co., Ltd., Daejeon, Republic of Korea. A 1N ADN-based propulsion system was designed to evaluate the performance of the propellant. By combining a thermal and catalytic bed in a reactor, the performance of the propellant was examined in a designed thruster (chamber pressure of 11 bar). A total of 16 tests, with pulse mode experiments, were conducted; the accumulated firing time was 285 s. The preheating temperatures were maintained between 350 and 400 °C to achieve steady-state combustion. Notably, the maximum combustion efficiency was 91%. Test 9 recorded the highest decomposition temperature of propellant in the catalyst bed (1422 °C). Interestingly, the combustion instability observed throughout this study was ≤0.5%. This study could assist in the further development of ADN-based propulsion systems.
