Rotor wing

A rotor wing is a lifting rotor or wing which spins to provide aerodynamic lift. In general, a rotor may spin about an axis which is aligned substantially vertically, fore-and aft, or side to side (spanwise). All three classes have been studied for use as lifting rotors, although only vertical-axis rotorcraft such as the helicopter have come into common use.
