Abstract: An assembly for providing flexure to a blade of a rotary blade system includes an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween. At least one of the upper and lower yoke surfaces has a layer of cushioning material positioned thereon and secured thereto. An alternate embodiment includes an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween and directly contacting the support plates wherein one of the curved surfaces is a non-circular arc that does not form part of the circumference of a circle. Another alternate embodiment includes a similar assembly having a twist-shank type of yoke for providing rotation of attached blades about their respective pitch axes.
Abstract translation: 用于向旋转叶片系统的叶片提供挠曲的组件包括具有上部弯曲表面的上部支撑板，具有下部弯曲表面的下部支撑板以及定位在它们之间的轭。 上部和下部磁轭表面中的至少一个具有定位在其上并固定到其上的一层缓冲材料。 一个替代实施例包括用于向旋转叶片系统的叶片提供挠曲的组件，该组件包括具有上弯曲表面的上支撑板，具有下弯曲表面的下支撑板以及定位在它们之间并直接接触支撑件的轭架 其中一个弯曲表面是不构成圆周的一部分的非圆形弧。 另一个可供选择的实施例包括一个类似的组件，该组件具有一个扭柄型的轭，用于提供连接的叶片围绕它们各自的俯仰轴线的旋转。
