The invention relates to a turbine module having a longitudinal axis X, comprising an unducted propeller (2) rotating about the longitudinal axis X and at least one straightener (25) comprising a plurality of unducted variable-pitch stator vanes (26) extending from a fixed housing along a radial axis Z perpendicular to the longitudinal axis X. According to the invention, the module comprises a system (30) for changing the pitch of the first stator blade (26), comprising:-at least one first control device (31) comprising a first fixed body (75) connected to the fixed housing and a first body (76) axially movable relative to the first fixed body, -at least one first engagement mechanism (32) engaging each stator vane (26) to the first moving body (76) of the first control device (31), the first engagement mechanism (32) comprising: 0-an engagement ring (30) centered on the longitudinal axis and engaged to the foot (28) of each stator vane, and 0-at least one rod (73) centered on the longitudinal axis and engaged to the foot (28) of each stator vane, the at least one lever is connected, on the one hand, to the engagement ring (60) and, on the other hand, to a first moving body (76) of the first control device.

    本发明涉及一种具有纵向轴线X的涡轮机模块,该涡轮机模块包括围绕纵向轴线X旋转的无涵道螺旋桨(2)和至少一个矫直器(25),至少一个矫直器包括多个无涵道可变桨距的定子轮叶(26),定子轮叶从固定壳体沿着垂直于纵向轴线X的径向轴线Z延伸。根据本发明,模块包括第一定子轮叶(26)的桨距改变系统(30),该桨距改变系统包括:●‑至少一个第一控制装置(31),至少一个第一控制装置包括被连接到固定壳体的第一固定主体(75)和相对于第一固定主体轴向移动的第一主体(76),●‑至少一个第一接合机构(32),至少一个第一接合机构将每个定子轮叶(26)接合到第一控制装置(31)的第一移动主体(76),第一接合机构(32)包括:●○接合环(30),接合环以纵向轴线为中心,并且被接合到每个定子轮叶的足部(28),以及●○至少一个杆(73),至少一个杆一方面被连接到接合环(60),另一方面被连接到第一控制装置的第一移动主体(76)。
