The evolution of a 1 Newton monopropellant thruster utilizing 87.5 % concentration hydrogen peroxide is reported. The design of the thruster is described, along with the testing of the catalyst material. Thruster firings were completed at sea-level atmospheric conditions and in vacuum, with a vacuum specific impulse of 160 seconds and a characteristic velocity efficiency of greater than 95 % achieved. The final thruster design demonstrated good overall performance, with initial lifetime testing suggesting that the catalyst offers good robustness. A case study suggests that the thruster would provide a level of performance comparable to that of a hydrazine-based propulsion system for a high velocity-change, volume-constrained Low Earth Orbit spacecraft mission, but at lower cost.

“…The pressure oscillations were measured as ±3.8%±3.8%, with 92.8% of efficiency in an additional firing test. These results have demonstrated the feasibility of an ethanol-blended hydrogen peroxide thruster as a high-performance and greenpropellant thruster for space missions [18].…”

Hydrogen peroxide, H2O2, is a promising and nontoxic oxidant. In recent years considerable attention has been paid to the development of hypergolic system compositions, because the use of them not only markedly simplifies the engine design and rocket system operation but also provides the possibility of their repeated use. Moreover, their high performance, high environmental compatibility and low toxicity make them highly preferable. The present review considers recent works on hypergolic systems involving hydrogen peroxide as the oxidizer and various green propellants of organic and inorganic nature with or without certain additives.

“…Future space activities and applications are broadening at greater rate, hence, more environmentally space propulsion system will be significantly increasingly desired. Over the last few years, low toxicity and less carcinogenic liquid propellants is an increasingly become a discussed subject as a potential candidate to replace the hydrazine-based propellants [1,8,9].…”

“…It is thermodynamically unstable, very reactive, decomposes slowly even in its most stabilized form, and possess a theoretically lower specific impulse than that of hydrazine [11]. However, hydrogen peroxide blended ethanol has a potential to be high-performance propellant in a monopropellant which possess equal or greater performance than hydrazine [9]. Rocket grade hydrogen peroxide or high-test peroxide (HTP) can be a fuel igniter in bipropellant system in addition to the oxidizer [12].…”

In monopropellant system, hydrogen peroxide is used with catalyst to create an exothermic reaction. Catalyst made of silver among the popular choice for this application. Since the catalyst used is in porous state, the effect of its porosity in the hydrogen peroxide monopropellant thruster performances is yet unknown. The porosity changes depending on factors including catalyst pact compaction pressure, bed dimension, and type of catalyst used. As researches on this topic is relatively small, the optimum porosity value is usually left out. The performance of the thruster indicated by the pressure drop across the catalyst bed. Porosity of the catalyst bed adds additional momentum sink to the momentum equation that contributes to the pressure gradient which lead to pressure loss inside thruster. The effect of porosity influences the performance and precision of the thruster. Study of the pressure drop by the catalyst bed requires a lengthy period and expensive experiments, however, numerical simulation by mean of Computational Fluid Dynamics (CFD) can be an alternative. In this paper, 90 wt% hydrogen peroxide solution with silver catalyst is studied in order to investigate the influence of porosity to the performances of the thruster, and to find the optimum porosity of the thruster. Species transport model is applied in the single-phase reaction simulation using the EDM for turbulence-chemistry interaction. Through this study, the effect of porosity towards the thruster performances represented in term of pressure drop, exit velocity, bed temperature, and thrust, and porosity of 0.4 found to be as an optimal value.
