Method of generating airfoil manufacturing coordinates based on cold airfoil was proposed. It comprised of ordering

interpolating

adding location bias

removing endwall fillet

and fitting endwall airfoil. This method was used to generate multistage axial compressor blade manufacturing coordinates. The difference between manufacturing coordinates and the cold airfoil below 0.01mm except near endwall section was found. Both the waviness of blade surface and curvature of leading or trailing edges were acceptable. Numerical results show the difference between manufacturing coordinate airfoil and cold airfoil has less impact on aerodynamic performance. Mass flow versus total pressure ratio and isentropic efficiency characteristics change little. Besides

flow velocity and flow angle of blade row inlet and outlet

and the detailed flow field have almost no changes. This method can be applied for generating airfoil manufacturing coordinates.
