GAS TURBINE ENGINE AIRFOIL ARRAY

An airfoil array (60) includes an endwall (64). A first airfoil (62) and a second airfoil (62) each extend radially from the endwall (64) and have a first side (66) and an opposite second side (68) that extends along an axial chord (92) between a leading edge (70) and a trailing edge (72). A first p...

Zusammenfassung:An airfoil array (60) includes an endwall (64). A first airfoil (62) and a second airfoil (62) each extend radially from the endwall (64) and have a first side (66) and an opposite second side (68) that extends along an axial chord (92) between a leading edge (70) and a trailing edge (72). A first profiled region (97) is recessed into the endwall (64) along the first side (66) of the first airfoil (62). A second profiled region (100) protrudes from the endwall (64) approximately equidistant from the first side (66) of the first airfoil (62) and the second side (68) of the second airfoil (62). A third profiled region (102) is recessed into the endwall (64) along adjacent the leading edge (70) of the second side (68) of the second airfoil (62). The third profiled region (102) is at least partially axially aligned with the second profiled region (100).
