    • An example section of a gas turbine engine includes a plurality of variable vanes circumferentially disposed about an engine axis, a first moveable annular ring disposed on an upstream side of the variable vanes, a second movable annular ring disposed on a downstream side of the variable vanes, and a plurality of vane arms, each including a first end secured to the first annular ring and a second end secured to the second annular ring. Movement of the first and second annular rings moves the vane arms, thereby actuating the plurality of variable vanes. An example variable vane assembly includes a vane arm including a portion that engages a variable vane, a first end configured to be secured to a first movable annular ring, and a second end configured to be secured to a second movable annular ring. Movement of the first and second annular rings moves the vane arms, thereby actuating the plurality of variable vanes. An example method of actuating a variable vane assembly includes the steps of securing a variable vane to a vane arm, the vane arm secured to a first movable annular ring at a first end and a second movable annular ring at a second end, and moving at least one of the first and second rings to move the vane arm.
    • 燃气涡轮发动机的示例部分包括围绕发动机轴线周向设置的多个可变叶片,设置在可变叶片的上游侧的第一可移动环形圈,设置在可变叶片的下游侧的第二可动环形圈 以及多个叶片臂,每个叶片臂包括固定到第一环形圈的第一端和固定到第二环形圈的第二端。 第一和第二环形圈的运动使叶片臂移动,从而致动多个可变叶片。 示例性可变叶片组件包括叶片臂,叶片臂包括接合可变叶片的部分,构造成固定到第一可移动环形圈的第一端和构造成固定到第二可动环形圈的第二端。 第一和第二环形圈的运动使叶片臂移动,从而致动多个可变叶片。 驱动可变叶片组件的示例性方法包括将可变叶片固定到叶片臂的步骤,叶片臂在第一端处固定到第一可移动环形圈,在第二端固定到第二可移动环形圈,并且在 移动叶片臂的第一和第二环中的至少一个。
