i. A rotating airfoil driven by a helicopter engine to produce vertical lift. Also called a rotor blade.
ii. A rotating airfoil driven by an aircraft engine to produce a thrust force approximately in line with the longitudinal axis of the aircraft. Also called a propeller blade. It is restricted to that part of a propeller arm or of a rotating wing from the shank outward (i.e., that part having an efficient airfoil shape that cleaves the air). See propeller.
iii. A rotating airfoil that is a part of a compressor in a gas turbine engine. Also called a compressor blade.
