Shroud/clamping Ring (Stator Blade Turbine) Deformation

  1. Jul 28, 2010 #1
    Hey guys,

    i have some problems here, i hope you can share some helpful information.

    it's about shroud ring and clamping ring (support ring) for stator turbine blades. These rings have a thermal deformation behavior (ovalisation), thus dent was found on the ring surface (caused by contact between blade pin and the ring).

    1. Will it really be a problem to achieve proper clearance during commissioning?

    2. Will blade have un-uniform of thermal clearance to shroud ring/stator casing?

    3. and how's the effects to the engine?

    Thanks
