Abstract:
A downwind morphing rotor that exhibits bending loads that will be reduced by aligning the rotor blades with the composite forces. This reduces the net loads on the blades which therefore allow for a reduced blade mass for a given maximum stress. Also provided is a pre-aligned configuration rotor whereby the rotor geometry and orientation does not change with wind speed, and instead is fixed at a constant downwind deflection consistent with alignment at or near the rated wind speed conditions. Also provided is a twist morphing rotor where the airfoil-shapes around the spars twist relative to the wind due to aerodynamic forces so as to unload the rotors when there is a gust. This can help reduce unsteady stresses on the blade and therefore may allow for reduced blade mass and cost. The twist morphing rotor may be combined with either downwind morphing rotor or pre-alignment rotor.
