The suitable fuel for reduced-toxicity hypergolic bipropellant has been explored in this study. High concentration of hydrogen peroxide and sodium borohydride were used as an oxidizer and a fuel additive for ignition source. Fuel candidates were narrowed down by many requirements such as toxicity, chemical regulation, storability, cost, specific impulse, solubility of additive and ignition delay. As a result, 3-methylaminopropylamine (MAPA) was selected as the best fuel for reduced-toxicity bipropellant. MAPA doped with sodium borohydride showed very fast hypergolicity with hydrogen peroxide and its ignition delay time was less than 10msec. MAPA and hydrogen peroxide bipropellant can achieve 98.3% of theoretical specific impulse of MMH/NTO, whereas MAPA has low toxicity compared with MMH.
