摘要

摘要: 基于面向对象的设计思想，设计出了一个双涵道变循环发动机（VCE）的性能计算模型，并选取了双涵道VCE具有代表性的典型工作点，进行了双涵道VCE的组合变几何调节的相关研究.结果表明：在双涵道VCE的亚声速巡航和超声速巡航工作点，合理调节风扇导流叶片角度可以更大程度发挥双涵道VCE性能优势；在亚声速巡航工作点时选取的方案4和超声速巡航工作点时选取的方案4均比双涵道VCE设计点的变几何调节方案性能更优.

Abstract: Based on object-oriented design thought, a caculation model of double bypass variable cycle engine (VCE) was built, and the typical engine work points were selected to study optimized method of combined variable geometry regulation. The results show that suitable adjustment of fan guide vane angle can adequately develop double bypass VCE performance advantage at subsonic cruise and supersonic cruise points of double bypass VCE. The scheme 4 at the subsonic and supersonic cruise points are all better than adjustment schemes at the design point.
