Abstract
A rotor blade 1 includes a main blade section 10, and an extension flap 20. The extension flap 20 is moveable relative to the main blade section 10. At least the main blade section 10 and the extension flap 20 form an airfoil lifting surface of the blade. A dimension of the airfoil lifting surface is variable by moving the extension flap 20 relative to the main blade section 10.
