Abstract: A load reduction assembly includes an annular bearing cone configured to extend between a bearing assembly and a frame assembly and form a first load path therebetween. The load reduction assembly further includes an annular recoupler member configured to extend between the bearing assembly and the frame assembly and form a second load path therebetween. The second load path is parallel to the first load path. The recoupler member includes a shape memory alloy configured to change stiffness in response to a change in a stress condition, thereby regulating an imbalance condition of a rotor shaft coupled to the bearing assembly.

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.

Abstract: A gas turbine engine includes a compressor section and a turbine section arranged in serial flow order. A shaft is provided rotatable with at least a portion of the compressor section and with at least a portion of the turbine section. A bearing is also provided supporting rotation of the shaft, with a support element in turn supporting the bearing. The gas turbine engine also includes a superelastic member formed of a shape memory alloy supporting at least one of the support element or the bearing. The superelastic member is installed in a pre-stressed condition to enhance a dampening function of the superelastic member.

Abstract: A variable inlet guide vane assembly (200) and methods of operating the variable inlet guide vane assembly (200) are disclosed. The variable inlet guide vane assembly (200) includes an inlet guide vane (210) and an actuator (220). The actuator (220) is at least partially embedded in the inlet guide vane (210) and is configured to change an angle of the inlet guide vane (210) relative to a gas flow. The actuator (220) includes a shape memory alloy. The methods of operating the variable inlet guide vane assembly (200) include modulating the shape memory alloy by transferring thermal energy between the actuator (220) and a fluid, and actuating the inlet guide vane (210) to change an angle of the inlet guide vane (210) relative to gas flow.
