| Abstract: | The detailed analysis on all kinds of national and international technical data of three-dimensional inverse method was carried out.According to the design requirements of high efficiency and high loading fan,the idea of fan airfoil design in stage environments by using three-dimensional inverse method was proposed.Numerical simulation and flow field analysis were performed in high pressure ratio single-stage fan.The feasibility of the inverse method in stage environments was validated from basic elements,single row to single stage.The blade loading distribution law was preliminarily studied.The airfoil inverse design technique of high efficiency and high loading fan was improved and developed further through above methods. |
