This paper presents a novel viscous inverse method for blade design. In this inverse design method the mass‐averaged tangential velocity and the blade thickness are prescribed, and the corresponding blade profile is sought. The blade profile is then computed iteratively using the discrepancies between the prescribed mass‐averaged tangential velocity distribution and its calculated distribution on an initial blade. The re‐design of an axial rotor blade, starting from an initial arbitrary profile in subsonic flow regimes, demonstrates the merits and robustness of this approach.
