The invention discloses an oversleeve configuration for a foldable bearingless rotor. The oversleeve configuration comprises a root connecting section, a typical section and an end connecting section,wherein the root connecting section and the typical section are in transition through a root transition section, and the typical section and the end connecting section are in transition through an end transition section; the root connecting section is symmetrically provided with first mounting connectors used for being connected with a shimmy damper, the front edge of the root connecting sectionis provided with a second mounting connector used for being connected with a variable-pitch rocker arm, and the cross section of the root connecting section is in a rounded rectangle shape. The crosssection of the typical section is in a rectangular shape with the two ends being of arc-shaped structures, and the inner diameter of the typical section is determined by the maximum shape change of the flexible beam assembled in the typical section; the front end of the end connecting section is of a pair of plate-shaped structures arranged in a spaced mode, and the upper surface and the lower surface of the end connecting section are provided with a first connecting connector used for being connected with the end of the flexible beam and a second connecting connector used for being connectedwith blades. The oversleeve configuration has the advantages of being small in size and small in aerodynamic resistance.
本发明公开了一种用于可折叠无轴承旋翼的袖套构型,包括根部连接段、典型段以及端部连接段,其中,根部连接段与典型段之间通过根部过渡段进行过渡,典型段与端部连接段之间通过端部过渡段进行过渡;根部连接段对称开设有用于和摆振阻尼器连接的第一安装接口,前缘开设有用于和变距摇臂连接的第二安装接口,根部连接段的横截面呈圆角矩形;典型段的横截面形状为两端为弧形结构的矩形,典型段的内径由其内部装配的柔性梁的最大形状变化来确定;端部连接段的前端部为一对间隔设置的板状结构,端部连接段的上表面、下表面开设有用于连接柔性梁端部的第一连接接口,以及用于连接桨叶的第二连接接口;本发明的袖套构型具有尺寸小、气动阻力小的特点。
