Abstract:
A wind turbine rotor blade includes a root portion and an airfoil portion extending from the root portion and defined by a leading edge and a trailing edge. The airfoil portion further includes a main foil section and a trailing edge section that is pivotally connected to the main foil section along a span-wise extending hinge line. A passive torsion element is coupled between the main foil section and the trailing edge section. The torsion element is biased to a neutral position wherein the trailing edge section is pivoted chord-wise to a low wind speed position relative to the main foil section. The trailing edge section is self-actuating from the low wind speed position to an increased wind speed position relative to the main foil section as a function of the biasing force of the torsion element and wind speed over the airfoil section.
