Abstract
The invention relates to a high-performance airfoil for a fan, in particular to a high-performance airfoil for a fan, which is designed by applying an advanced pneumatic analysis technology in an aviation technology according to actual working conditions of low Reynolds number (generally lower than 106) of a small-size and low-rotating-speed fan; the invention discloses a maximum camber and a position thereof of the airfoil, a maximum thickness and a position thereof, an equation satisfied by upper and lower surfaces and an airfoil coordinate; f is the maximum camber; Xf is a transverse coordinate value of the maximum camber of the airfoil; t is the maximum thickness; Xt is a transverse coordinate vale of the maximum thickness of the airfoil; and C is a chord length. An original point of a coordinate system of the airfoil is defined as a front edge point of a middle arc line of the airfoil; an X axle is overlapped with a chord line; the direction is to point to the airfoil back edge from the airfoil front edge; and a Y axle is perpendicular to a direction of bending the X axle to the middle arc line of the airfoil. Under the same working conditions, compared with a traditional fan airfoil, the fan adopting the airfoil is better in matchability with actual working conditions, higher in air volume, lower in noise and higher in energy efficiency value.
