叶 片 多 尺 度 表 面 对 压 气 机 气 动 性 能 影 响 及 其高 性 能 制 造 研 究 进 展

Blade geometry error refinement control，surface corrugation control and reasonable arrangement of meso-microscopic bionic drag reduction structure are effective means to improve the aerodynamic performance of aeroengine compressor blades，and is also currently one of the key focuses of thenext generation of aero-engines. These structures usually have complex geometries and are difficult to manufacture. In this paper，we firstly review the changes of different scale surface features，such as blade geometry error，waviness and meso-microscopic bionic drag reduction structure，on the flow field characteristics，as well as the influence of different scale surface structural features on the aerodynamic performance of compressor，and analyze the manufacturing process of multi-scale surfaces and its latest progress. Secondly，the requirements for geometric shape tolerance range，waviness and meso-microscopic bionic structure manufacturing technology in the high-performance manufacturing of compressor blades under aerodynamic performance constraints are introduced. Finally，the research content and development direction for further enhancing the aerodynamic performance of compressor blades are prospected in the light of the current development of high-performance manufacturing of multi-scale surfaces.
