摘　　要：为了提高带核心驱动风扇的压气机的气动性能,研究核心驱动风扇与压气机的匹配设计技术是非常必要的,两者的匹配对下一代发动机核心压缩部件性能至关重要。核心驱动风扇与压气机的匹配设计需要考虑4个主要的方面:一维匹配设计、子午布局匹配设计、叶片造型参数匹配设计和二维流场匹配,在此设计基础上开展全三维的匹配分析以及部件试验验证。试验结果表明:串装试验结果与全三维模拟的不同涵道比的核心驱动风扇和压气机特性变化趋势是一致的,验证了高效率核心驱动风扇与压气机匹配设计方法的有效性,揭示了核心驱动风扇和压气机性能匹配随涵道比变化的基本规律,涵道比增加,核心驱动风扇压比匹配低,从而导致压气机压比匹配得更高,反之涵道比减小,压气机匹配压比则更低。In order to improve the aerodynamic performance of compressor with core driven fan stage,it is essential to study the matching of core driven fan stage and high pressure compressor witch,which is of great importance to the core compressor component on next generation engine.Four issues should be considered on the matching of core driven fan stage and high pressure compressor:the matching design of one-dimensional,the matching design of through-flow,the matching design of blade modeling parameter,the matching of two-dimensional flow field,then three-dimensional simulation analysis and testing investigation were carried out.The testing results showed that:the variation tendency of core driven fan stage and high pressure compressor performance was coincident with three-dimensional simulation and the testing results,which verified the effectiveness of the matching performance of high efficiency core driven fan stage and high pressure compressor.By increasing the bypass ratio,the pressure ratio of core driven fan stage could be lower,bringing about the increase of the pressure ratio of high pressure compressor.On the contrary,the decrease of bypass ratio could lead to the lower pressure ratio of high pressure compressor.
