摘　　要：为探讨高效高负荷高通流能力风机的关键气动设计技术及其内部流动机理,本文完成了一台压比为1.20,载荷系数为0.83的轴流风机设计。详细研究了流量系数、反力度等设计参数的影响规律,并给出了相应的选取原则;分析了叶片负荷调整、叶片弯曲、叶片端弯对叶栅内流动、级匹配、级性能的影响,给出了高负荷轴流风机三维叶片设计的基本原则;此外,本文还开发了S1流面协同优化方法,有效地降低了静叶损失,提高了风机裕度。To discuss the key aerodynamic design techniques and the internal flow mechanism of highly efficient,highly loaded fans with large flow capacity, an axial fan was designed with a pressure ratio of 1.2 and a loading coefficient of 0.83. The influence of design parameters such as the flow coefficient and the reaction is studied in detail, and the corresponding selection principles are given. The influence of blade loading adjustment, blade bowing and blade re-cambering on the flow in the cascade passages, flow matching and stage performance is analyzed, and the basic principles of the three-dimensional blading of highly loaded axial fans are discussed.Besides, a synergistic optimization method of the S1 flow surface is developed, which effectively reduces the stator losses and improves the fan margin.
