rotor blade

Also found in: Dictionary, Thesaurus, Medical, Wikipedia.

blade

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.

The advantages of improved work hygiene due to the minimized isocyanate content are particularly evident during this overhaul of wind turbines or during repair work on the rotor blades. Complex protective measures could thus be dispensed with, which would lead to greater productivity without compromising on health protection.
