Abstract

Solid paraffin wax doped with sodium borohydride powder can achieve hypergolic ignition in contact with 90 % hydrogen peroxide. This phenomenon is mainly due to the intense redox reaction of sodium borohydride with 90 % hydrogen peroxide, which exotherms and increases the ignitability in solid paraffin fuels. In this study, drop-on-solid tests were conducted under atmospheric conditions to quantify the ignition delay time, which was observed to be lower than 5 ms, indicating that hypergolic ignition in this innovative system is both rapid and efficient, and to characterize the spontaneous ignition behavior. The results obtained confirm the practical feasibility of hypergolic ignition for the selected propellant combinations. In this study, a hybrid rocket motor prototype was designed for engine firing test, and the results showed that the engine combustion efficiency was higher than 87 % under low oxidant-fuel ratio conditions. Its low-delay characteristic makes it suitable for use in areas requiring fast response such as satellite attitude and orbit control.
