Abstract:
A wind turbine blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the blade segments having a pressure side shell member, a suction side shell member. The blade further including a coupling component extending spanwise and structurally connecting the first blade segment and the second blade segment. A thermal actuation component is coupled to the coupling component and passively actuated in response to a change in thermal conditions so as to provide for aeroelastic tailoring and pitch control to the wind turbine blade.
