Definitions

  • This invention is directed generally to stator vane airfoils within gas turbine engines, and more particularly to support systems for stator vane airfoils.
  • Turbine engines typically include a plurality of rows of stationary compressor stator vanes extending radially inward from a shell and include plurality of rows of rotatable compressor blades attached to a rotor assembly for turning the rotor.
  • Conventional turbine engines often include a segment with multiple stationary airfoils collectively referred to as a stator.
  • Stator segments deflect in the upstream direction under steady gas pressure loading, and the deflection varies around the circumference dependent upon how the segment is constrained to the casing. The unconstrained ends of the segment deflect more and have less axial clearance to the upstream rotor disk.
  • a compressor stator vane segment including a connection system that enables stator vane alignment while enabling an individual stator vane to be replaced is disclosed.
  • the stator vane connection system includes a radially extending inner support extending from a stator vane, whereby the inner support is secured to forward and aft inner rings via a removable, inner axial bolt.

  • the stator vane connection system includes one or more first outer alignment pins that aligns the stator vane and is positioned within the portion of the outer diameter platform of the stator vane, whereby the first outer alignment pin aligns the stator vane.
  • the compressor stator vane segment is formed from a stator vane including an airfoil formed from an outer wall, and having a leading edge, a trailing edge, a pressure side, a suction side, an inner diameter platform at a first end of the airfoil, and an outer diameter platform at a second end of the airfoil.
  • the compressor stator vane segment includes a stator vane connection system.

  • At least one first inner pin is positioned within the portion of the inner support of the stator vane to which the inner axial bolt is attached.
  • the first inner pin aligns the stator vane relative to an adjacent stator vane.
  • One or more first outer alignment pins are positioned within the portion of the outer diameter platform of the stator vane, whereby the first outer pin aligns the stator vane relative to an adjacent stator vane.
  • the stator vane connection system may also include an outer tie bar coupled to the outer diameter platform.

  • the inner axial bolt may include threads that engage threads within the second inner ring.
  • the inner axial bolt may include a head that is larger than a shaft of the axial bolt, and the first inner ring may include a head receiving cavity in which the head of the inner axial bolt resides.
  • the compressor stator vane segment may be assembled in a number of ways.
  • the compressor stator vane segment may be assembled by milling the airfoil, coating the airfoil flow path surfaces, turning the outer ring from a rolled ring, turning the forward inner ring from a custom forging, turning the aft inner ring from a custom forging, drilling holes in the outer ring, drilling holes in the inner forward ring, drilling holes in the aft inner ring, brazing a forward honeycomb seal to the forward inner ring, brazing an aft honeycomb seal to the aft inner ring, turning the forward honeycomb inner diameter, turning the aft honeycomb inner diameter, sawing the outer ring in half, sawing the forward inner ring in half, sawing the aft inner ring in half, and assembling the stator vanes and rings with bolts and pins and stake the fasteners.
