美国自适应循环发动机的发展历程

Development process of adaptive cycle engine in the United States

自适应循环发动机以其高效的涵道比调节能力和良好的流量保持能力,成为下一代战斗机和未来超声速客机的理想动力装置。鉴于美国在自适应循环发动机领域长期保持领先地位,本文将美国自适应循环发动机的发展历程分为4个阶段,叙述了美国一系列军/民用研究计划下自适应循环发动机的发展历程、技术关联和结构特点,梳理出自适应循环发动机的基本结构形式,总结了总体性能设计、进气道/发动机匹配、低排放、低噪声、先进材料和增材制造等自适应循环发动机的关键技术及发展历程,从而为我国自适应循环发动机的发展提供一定的参考。

The efficient bypass ratio regulating ability and good flow holding capacity are the advantage of adaptive cycle engine,leading to its becoming the ideal power device for next generation fighter and future supersonic civil aircraft.In view of the long-term leadership of the United States in the field of adaptive cycle engine,the development process of the adaptive cycle engine in the United States was divided into four stages,and the development process,technical correlations and structural features of adaptive cycle engines under a series of military/civil research projects were described.The basic structural form of adaptive cycle engine was sorted out.The key technologies and development process of adaptive cycle engine such as overall performance design,inlet/engine matching,low emission,low noise,advanced materials and additive manufacturing were summarized so as to provide some reference for the development of adaptive cycle engine in China.
