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. Source
