Abstract: convenient and speedy used for aeromechanic design and calculation of turbine cascade profiles, based on numerical integral to full potential equations and AF2 (Approximate Fatorization) procedure, is presented, which is applicable to steady subsonic, transonic and supersonic flows. Compared with the scheme using artificial compressibility in supersonic zone, which is very popular at present, this method shows its obvious superiorities.
