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: A pitch control system for blades on a rotor of an aircraft has a gimballing rotor hub and a plurality of step-over arms connected to the hub and capable of pivoting relative to the hub about a pivot axis. Each of a plurality of pitch links connects one of the step-over arms to a flight control system for pivoting the connected step-over arm about the pivot axis and relative to the hub in response to inputs from the control system. Each of a plurality of step-over links connects one of the step-over arms to one of the blades for rotating the associated blade about the pitch axis in response to pivoting of the associated step-over arm.
Abstract translation: 用于飞行器转子上的叶片的俯仰控制系统具有g球转子轮毂和连接到轮毂并能够相对于轮毂围绕枢转轴线枢转的多个步进臂。 多个音调链接中的每一个将分步臂中的一个连接到飞行控制系统，用于响应于来自控制系统的输入而使连接的分离臂围绕枢转轴线并相对于轮毂枢转。 多个翻转链接中的每一个将所述翻转臂中的一个连接到所述叶片中的一个，用于响应于所述相关联的翻转臂的枢转而围绕所述俯仰轴线旋转相关联的叶片。
