This invention relates to a rotor blade airfoil of an axial-flow turbomachine, more particularly for a fan or a compressor high-pressure stage of a gas turbine system, having means in the tip area to improve supersonic performance. In accordance with the present invention, the blade afflux edge has a forward-back sweep. The tip region of the blade efflux edge can be designed essentially similar to the blade afflux edge, with the tip region extending across the outer 15% to 25% of the blade span.
