| Abstract: | Based on calculation model of an energized mixed turbofan engine used for unmanned combat aerial vehicle,three typical work points were selected to study the influence of fan inlet guide vanes,compressor IGV and nozzle throat area,ect.on the thrust performance of engine.The results show that the engine thrust of 0 km 0.2 M working condition point increases 0.55%and 0.48%,and the engine thrust of 5 km 0.9 M working condition point increases 0.24%and 0.32%respectively after opening fan IGV 1 degree and reducing nozzle throat area 1%.Opening compressor IGV only affects engine thrust at 0.1 km 0.8 M point.The thrust rises up to 1.38%after opening 1 degree. |
