Abstract
The torsional rigidity of a wind turbine blade affects the twist response of the blade induced by bending moments within the blade. By including regions having a lower modulus of rigidity than the remainder of the blade shell, the torsional rigidity of the blade shell can be decreased, and the twist response thereby increased. In blades having a single shear web, this twist response may be more pronounced. The regions of low modulus may comprise additional shell panels, or thick regions of low modulus joining material.
