Abstract
A compressor aerofoil for a turbine engine or an axial process compressor, the compressor aerofoil includes a suction surface wall having a suction surface and a pressure surface wall having a pressure surface, the suction surface wall and the pressure surface wall meet at a leading edge and a trailing edge and define a tip having a tip surface, the aerofoil has a maximum thickness Tmax. A mean camber line is defined as passing through the leading edge and the trailing edge. The compressor aerofoil further includes a winglet at the tip and which extends from the suction surface, the winglet has an overhang W that has a perpendicular extent from the suction surface in the range 0.1Tmax to 1.5Tmax. The winglet has a maximum overhang Wmax that occurs within 50% of the length of the mean camber line from the leading edge.
