摘　　要：结合RBCC组合动力的发展需求,从性能、使用情况等方面探讨近年来组合动力吸气式模态用燃料和火箭模态用推进剂的研究进展,包括吸热型碳氢燃料、高密度吸热碳氢燃料、四氧化二氮/绿色自燃燃料和过氧化氢/碳氢燃料等。为满足RBCC系统对推进剂的长贮需求,RBCC吸气式模态宜发展兼顾高密度和高吸热能力的碳氢燃料;火箭模态需发展能够与四氧化二氮迅速自燃,且能量不低于现有肼类燃料的新型绿色燃料;过氧化氢/碳氢燃料需重点解决过氧化氢使用安全性和长贮稳定性问题,并形成可靠的安全应用方案。针对RBCC动力系统提出的可长期贮存、免维护等要求,现有推进剂方案还需要在性能提升、工程适用性、系统匹配性等方面继续开展关键技术攻关。Combined with the development requirements of RBCC engine, the latest research of the fuels for air-breathing mode and the propellants for all-rocket propulsion system with the aspects of performance and usability is discussed, including endothermic hydrocarbon fuel, high-density endothermic hydrocarbon fuel, nitrogen tetroxide/green hypergolic fuel and hydrogen peroxide/hydrocarbon fuel.In order to meet the long-term storage requirements of propellant for RBCC system, it is necessary to develop the hydrocarbon fuels with both high density and strong heat sink for the air-breathing mode. Correspondingly, the new green hypergolic fuels should be developed for the rocket mode, which can spontaneously have the low ignition delay with nitrogen tetroxide and the high specific impulse.Meanwhile, the safety and storage stability of hydrogen peroxide should be promoted with a reliable safety control method.In view of the long-term storage and maintenance-free requirements of RBCC system, the existing propellant schemes still need to carry out key technological breakthroughs in performance improvement, engineering applicability, system matching and other aspects.
