美国自适应发动机研究的进展与启示

为借鉴和参考美国自适应循环发动机的研究与研制经验,综述了美国变循环发动机演变至自适应发动机的3个发展阶段,重点介绍了其在多用途经济可承受的先进涡轮发动机(VAATE)研究计划下的自适应通用发动机技术(ADVENT)分计划、自适应发动机技术验证(AETD)分计划、自适应发动机过渡(AETP)分计划和空中优势自适应推进技术(ADAPT)分计划的开发与验证情况。分析总结出美国自适应发动机具有以下特点:技术先进且应用前景广泛,代表未来发展方向;变循环与自适应循环技术均不成熟,还需深入验证;技术研究采用竞争策略实施。

Progress and Revelation of US Adaptive Cycle Engine Development

In order to assimilate the experience of US adaptive cycle engine development, three phases from variable cycle engine to adaptive cycle engine were presented, the progresses and demonstration of development programs were summarized particularly from VAATE, ADVENT, AETD, AETP and ADAPT technology programs. Analying of US adaptive cycle engine shows that the advanced technologies and the wide application prospects must represent the development direction of future. The technologies of the variable cycle engine and the adaptive cycle engine are still on its infancy, need to be demonstrated. The technology investigations are conducted with competition strategy.
