Abstract (en)

A compressor section (14) includes a compressor casing (48) that has an upper casing portion (60) coupled to a lower casing portion (62) such that a split-line (64) is defined between the upper casing portion (60) and the lower casing portion (62). A split-line stator vane assembly (70) includes a first split-line stator vane (76) that has a first shank (75) with a first platform portion (84) and a first mounting portion (86) that extends radially outward of the first platform portion (84). A first airfoil (88) extends radially inward of the first platform portion (84). The first platform portion (84) includes a protrusion (80) that extends circumferentially beyond the split-line (64). A second split-line stator vane (78) has a second shank (79) with a second platform portion (94) and a second mounting portion (96) that extends radially outward of the second platform portion (94). A second airfoil (88) extends radially inward of the second platform portion (94). The second platform portion (94) includes a recess (82) that extends circumferentially away from the split-line (64).
