Summary:The invention discloses a large wind tunnel axial flow blade design method and device. The method comprises the steps that firstly, size parameters of the axial flow fan blade are set, the blade is divided into different sections from the blade bottom to the blade top, any section is taken in the height direction of the blade, and current blade section parameters are determined; based on the radius of each section of the blade, obtaining the length of a blade-shaped chord line and an included angle between inlet and outlet tangential speed and axial speed of a blade section chord line; obtaining a chord line bending angle according to a chord line distribution function of each section of the blade and an average value of included angles between inlet and outlet tangential speeds and axial speeds; obtaining an included angle between a blade profile chord line and an axis corresponding to the section of the blade according to the blade profile mounting angle distribution function, and obtaining an angle distrib
