compressor blade

[kəm′pres·ər ‚blād]
(mechanical engineering)
The vane components of a centrifugal or axial-flow, air or gas compressor.

compressor blade

A rotating aerofoil on the disc of a compressor in a gas turbine engine. A compressor blade adds energy to the air by increasing its pressure and density as it moves through the engine. Compressor blades are made of special steel, alloys, or materials that do not usually distort or creep appreciably under high loads at elevated temperatures.
