摘要： A spar for a rotor blade assembly is provided including a generally hollow tubular body. A spacer protrudes from at least one surface of the body along a length of the body. A hole extends through the body and the spacer. The hole is configured to align with a through hole in an adjacent flexbeam assembly. The spacer is configured to contact a surface of the adjacent flexbeam assembly to create a match fit between the body and the flexbeam assembly.

摘要： A rotor blade assembly includes one or more flex-beam members and a torque tube surrounding the one or more flex-beam members and extending at least partially along a rotor blade assembly length. A pitch bearing assembly is supportive of the torque tube relative to the one or more flex-beam members and includes at least two outer bearing members secured to the torque tube and an inner bearing member positioned at least partially within the at least two inner bearing members and secured to the one or more flex beam members. A change in a stiffness of the inner bearing member changes one or more dynamic characteristics of the rotor blade assembly.
摘要翻译：转子叶片组件包括一个或多个挠曲梁构件和围绕一个或多个弯曲梁构件并且至少部分地沿着转子叶片组件长度延伸的扭矩管。变桨轴承组件相对于一个或多个挠性梁构件支撑扭矩管，并且包括固定到扭矩管的至少两个外部轴承构件和至少部分地定位在至少两个内部轴承构件内的内部轴承构件并固定到一个或多个弯曲梁构件。内轴承构件的刚度的变化改变了转子叶片组件的一个或多个动态特性。

摘要： A pitch bearing for connecting first and second articles is provided. The first article includes a first curved outer surface and the second article includes a second curved outer surface opposite the first curved outer surface. The pitch bearing includes an axisymmetric structure interposed between the first and second curved outer surfaces. The axisymmetric structure includes compliant layers and stabilizing layers interleaved between the compliant layers. The compliant layers and the stabilizing layers proximate to the first article haves a curvature matching that of the first curved outer surface. The compliant layers and the stabilizing layers proximate to the second article have a curvature matching that of the second curved outer surface. A shear stiffness of each of the stabilizing layers is greater than a shear stiffness of each of the compliant layers.
摘要翻译：提供了用于连接第一和第二物品的变桨轴承。第一制品包括第一弯曲外表面，第二制品包括与第一弯曲外表面相对的第二弯曲外表面。俯仰轴承包括插入在第一和第二弯曲外表面之间的轴对称结构。轴对称结构包括顺应层和在柔性层之间交错的稳定层。靠近第一制品的柔顺层和稳定层具有与第一弯曲外表面的曲率匹配的曲率。靠近第二制品的顺应层和稳定层具有与第二弯曲外表面匹配的曲率。每个稳定层的剪切刚度大于每个顺应层的剪切刚度。
