Compressor blade for a gas turbine engine

摘要

A blade (11) as a main body of a rotor blade has a suction side (11a) made convex and a pressure side (11b) made concave so as to have an aerofoil profile. A squealer tip (17) having a back face (17a) continuous to the suction side and a front face (17b) matching with a center plane of the blade (11) is formed as a distal end of the blade. The front face (17b) is coated with a hard coating.
