  • Publication number: 20210070015
    Abstract: A laminate assembly includes a matrix layer and elongated, continuous strips of a conductive alloy. The matrix layer has opposite first and second sides connected by opposite first and second edges. Each of the first and second edges extends from the first side of the matrix layer to the opposite second side of the matrix layer. The elongated, continuous strips of the conductive alloy are disposed in the matrix layer between the first and second sides of the matrix layer. The elongated continuous strips continuously extend through the matrix layer from the first edge to the opposite second edge.

  • Patent number: 10724400
    Abstract: A support assembly for a load-bearing unit, a gas turbine engine including the support assembly, and a method of operation of the support assembly are provided. The support assembly includes a support element, a damper, and a variable stiffness member. The support element supports the load-bearing unit. The damper supports the support element and is configured to provide dampening of the load-bearing unit. The variable stiffness member is positioned between the damper and the load-bearing unit. The variable stiffness member is configured to provide a serial dampening of the load-bearing unit with the damper. The variable stiffness member includes a shape memory alloy.

  • Patent number: 10626846
    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.

  • Publication number: 20190178104
    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.

  • Patent number: 10196934
    Abstract: A rotor support system for a gas turbine engine may generally include a bearing assembly and a load reduction member configured to be coupled between the bearing assembly and a support frame of the engine. The load reduction member may include a fuse portion configured to fail when a load transmitted through the load reduction member exceeds a predetermined load threshold. The system may also include a load recoupling member provided between the bearing assembly and the support frame. The load recoupling member may be formed from a super-elastic shape memory alloy that allows the load recoupling member to undergo recoverable deformation without failing when the fuse portion fails such that the load recoupling member maintains a mechanical connection between the bearing assembly and the support frame.

  • Patent number: 9803617
    Abstract: A wind blade includes a self-supporting structural framework, having a span-wise member, a plurality of chord-wise members, a fabric skin, and at least one of a stiffener and a mechanical element. The plurality of chord-wise members is coupled to the span-wise member and each chord-wise member and the span-wise member maintains an aerodynamic contour of the wind blade. Further, the fabric skin is disposed over the self-supporting structural framework. The stiffener and/or the mechanical element are coupled to the self-supporting structural framework, and are operable to provide a relative movement to the self-supporting structural framework for adjusting the aerodynamic contour and provide pretension to the fabric skin.

  • Patent number: 9605650
    Abstract: A wind blade is provided. The wind blade includes a self-supporting structural framework, having multiple chord-wise members and one or more span-wise members. Each of the multiple chord-wise members and the one or more span-wise members have an aerodynamic contour. The wind blade also comprises a fabric skin located over the self-supporting structural framework. Further, the wind blade includes a tensioning mechanism configured for providing pretensioning in the fabric skin. The tensioning mechanism includes multiple mechanical force elements coupled with the fabric skin for providing a predetermined force for maintaining an aerodynamic surface of the fabric skin during operation of the wind blade.
