摘要
参考现代民航飞机设计方案要求,完成了开式转子发动机叶片的气动设计工作。在设计过程中引入可压缩流动叶片数据改进了螺旋桨片条理论,使之适用于高亚声速来流的叶片设计。采用后掠叶片,NACA16系列叶型,前缘积叠方式。数值模拟结果与设计结果相近,基本满足气动设计要求。
Aerodynamic design of open rotor blade which refers to performance of engines which used on modern civil airplane is completed. Compressible blade data is introduced to optimize strip theory in order to satisfy blade design under high subsonic free stream. Sept blade, NACA-16 series data and leading edge accumulation is used. Numerical simulation is similar to the design which basicaly satisifed the design requirements.
