自适应循环发动机总体设计技术探讨

Discussion on overall performance design technology of adaptive cycle engine

自适应循环发动机是下一代飞行器的重要候选动力装置。在简要介绍国内外研究进展之后,重点对目前开展的自适应循环发动机总体设计研究进行综述:首先介绍典型的自适应循环发动机总体性能方案及结构形式,然后讨论自适应循环发动机的性能收益和代价,并对未来的总体设计发展趋势进行展望。认为未来自适应循环发动机总体设计应在并行多/变维度、多学科优化体系下开展,考虑多源不确定性因素的影响,可引入混合维度仿真方法评估新颖部件技术特征,并结合飞行任务需求开展飞机/发动机的综合性能优化。

The adaptive cycle engine is an important candidate power unit for the next generation of aircraft.After a brief introduction of the research progress at home and abroad,focuses were put on the overall design research of the adaptive cycle engine currently carried out.Firstly,the overall performance scheme and structural form of the typical adaptive cycle engine were introduced.Then,the performance benefits and costs of the adaptive cycle engine were discussed.Finally,the overall design development trend of the future was presented.It is believed that the overall design of adaptive cycle engines in the future should be carried out under the parallel multi-dimensional and multi-disciplinary optimization system,considering the influences of multi-source uncertainties.Hybrid-dimensional simulation methods can be applied to evaluate the technical characteristics of novel components,and the comprehensive performance optimization of aircraft/engines can be carried out according to the requirements of flight missions.
