过氧化氢（H2 O2）/煤油双组元推进剂具有能量高、贮存密度大、环境友好等优点，是一种很有前途的双组元推进剂。使其自燃的可能性使这一选择更具吸引力。采用不同的候选催化剂和助剂组合制备了H2 O2/煤油自燃双组元推进剂。通过使用跌落试验方法进行初步筛选评价。然后，在一台专门设计的推力发动机上研究了通过满足投放试验要求的组合体的推进性能。结果表明，无论在稳态还是脉冲工况下，均能获得较短的点火延迟期和可靠的推进性能，煤油与添加剂和90%浓度H2 O2的组合在贮存3个月后仍能保持良好的性能。H_2O_2和煤油的组合有望成为目前使用的可贮存有毒推进剂的有效替代物。
Hydrogen peroxide (H2O2)/kerosene is a prospective bipropellant due to its high-energy content, high storage density, and environmentally benign properties. The possibility of making it hypergolic renders this option even more attracting. Self-ignitable H2O2/kerosene bipropellants were prepared by combining different candidate catalysts and promoters. Preliminary screening evaluations were conducted by using a dropping-test method. Propulsive performances of the combinations having passed satisfying dropping-test requirements were then investigated on a specially designed thrust engine. The results revealed that short ignition delay and reliable propulsion performances could be acquired in both steady-state and pulse-mode operations, and the combination of kerosene with additives and H2O2 of 90% concentration could still have good performances after 3 months storage time. It is expected that the combination of H2O2 and kerosene can be an efficacious alternative for storable toxic propellants used currently.
