【摘要】 吸热碳氢燃料及其应用研究已经成为高超声速推进系统研发中的重大关键技术之一。提出了基于燃料化学组成-性质的定量关系,确定了JP-7型吸热碳氢燃料的理论化学组成域,配制了不同组成的燃料样品,验证了理论设计的可靠性。系统研究了RP-3燃料中加入脱氧剂与裂解结焦抑制剂对结焦物生成的影响规律,结果表明,添加剂可以显著提高RP-3燃料的热安定性,为解决RP-3燃料热沉与结焦物生产的瓶颈问题提供了实验与理论基础。更多还原

【Abstract】 Endothermic hydrocarbon fuel is one of most crucial technologies in the development of hypersonic propellant system.The reasonable composition regimes for JP-7 jet fuel were theoretically predicted based on quantitative chemical composition-properties relationships reported previously.Several fuel samples were prepared to verify the reliability of theoretical results.The influence of oxygen scavenger and coke inhibitor on the formation of pyrolytic coke was systematically investigated.It is found that those additives is favorable for the improvement of thermal stability at elevated temperature.更多还原
