CERAMIC GAS TURBINE ENGINE AIRFOIL WITH 3 ZONES FILM COOLING HOLE PATTERN HAVING DIFFERENT PITCH
An airfoil (60) includes a ceramic airfoil section (62) that defines leading and trailing edges (62a, 62b), pressure and suction sides (62c, 62d), and radially inner and outer ends. The radial span (S) of the airfoil section (62) has first, second, and third radial span zones (Z1, Z2, Z3). There is...

| description | An airfoil (60) includes a ceramic airfoil section (62) that defines leading and trailing edges (62a, 62b), pressure and suction sides (62c, 62d), and radially inner and outer ends. The radial span (S) of the airfoil section (62) has first, second, and third radial span zones (Z1, Z2, Z3). There is a row (70) of cooling holes (72) in an aft 25% of the axial span (A1). The row (70) of cooling holes (72) extends though the first, second, and third radial span zones (Z1, Z2, Z3). The cooling holes (72) in the first radial span zone (Z1) define a first pitch P1, the cooling holes (72) in the second radial span zone (Z2) define a second pitch P2, and the cooling holes (72) in the third radial span zone (Z3) define a third pitch P3, wherein P2 < P3 < P1. |
