Abstract: In one embodiment, a rotor blade may comprise a blade body, a spar structure, and a blade nose. The blade body may comprise a skin, wherein the skin is configured to form an airfoil shape, and wherein the airfoil shape comprises an inboard end, an outboard end, a leading edge, and a trailing edge. The spar structure may comprise a first spar cap and a second spar cap, wherein the first spar cap is coupled to an upper portion of the skin, and wherein the second spar cap is coupled to a lower portion of the skin. The blade nose may comprise a cavity, wherein the cavity is configured to house a plurality of modular weights at a plurality of radial blade locations, wherein the plurality of radial blade locations comprises a range of locations between the inboard end and the outboard end.

Abstract: According to one embodiment, a constant velocity (CV) joint includes a first yoke, a second yoke, and a control mechanism. The first yoke is configured to be rotatably coupled to an input device about a first axis and configured to receive the input device through a first opening. The second yoke is rotatably coupled to the first yoke about a second axis and rotatably coupled to an output device about a third axis. The control mechanism is adapted to constrain the first yoke and the second yoke so as to achieve a substantially CV characteristic between the input device and the output device.
Abstract translation: 根据一个实施例，等速（CV）接头包括第一磁轭，第二磁轭和控制机构。 第一磁轭被配置成围绕第一轴线可旋转地联接到输入装置，并且被配置成通过第一开口接收输入装置。 第二轭被围绕第二轴可旋转地联接到第一轭，并且围绕第三轴可旋转地联接到输出装置。 控制机构适于约束第一磁轭和第二磁轭，以便在输入装置和输出装置之间实现基本的CV特性。
