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.

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.

Abstract translation: 提供风叶。 风叶片包括自支撑结构框架，具有多个弦向构件和一个或多个跨度构件。 多个弦向构件和一个或多个跨度构件中的每一个具有空气动力学轮廓。 风叶片还包括位于自支撑结构框架上方的织物皮肤。 此外，风叶片包括构造成用于在织物皮肤中提供预张紧的张紧机构。 张紧机构包括与织物皮肤联接的多个机械力元件，用于在风力叶片的操作期间提供用于维持织物表皮的空气动力学表面的预定力。
