    • PROBLEM TO BE SOLVED: To provide a shrouded gas turbine blade or an active tip clearance control of a moving blade.SOLUTION: A rotor assembly has a rotor 10 supporting a plurality of wheels axially disposed with spaces. Each wheel is provide with an annular row 14 of the moving blades and in the plurality of wheels, the moving blades of the annular row have are provided with an outside in radial direction chip shroud 16 where a seal tooth 18 is provided. A stator assembly includes a radially inward facing axially-stepped surface, formed with radially inner and outer seal surfaces 20 and 24 radially connected by a shoulder. The stator assembly and rotor assembly are moveable axially relative to each other, enabling selective positioning of the at least one seal tooth radially opposite one of the radially inner and outer seal surfaces to thereby selectively alter a clearance gap C1 between the one seal tooth and the radially inward facing axially-stepped surface.
    • 要解决的问题:提供一种被覆盖的燃气轮机叶片或活动叶片的主动顶端间隙控制。解决方案:转子组件具有支撑轴向设置有空间的多个轮的转子10。 每个轮子设置有活动叶片的环形排14,并且在多个轮中,环形排的活动叶片在径向切屑罩16上设置有设置密封齿18的外侧。 定子组件包括径向向内的轴向台阶表面,形成有径向地由肩部径向连接的内部和外部密封表面20和24。 定子组件和转子组件可以相对于彼此轴向移动,使得至少一个密封齿能够与径向内部和外部密封表面之一径向相对地选择性地定位,从而选择性地改变一个密封齿和第二密封齿之间的间隙C1 径向朝内的轴向台阶表面。
