Document Type and Number:
Japanese Patent JP4482273
Kind Code:
B2
Abstract:
A method for fabricating a nozzle for a gas turbine engine facilitates extending a useful life of the nozzles. The nozzle (51) includes an airfoil (52). The method includes forming the airfoil to include a suction side (60) and a pressure side (62) connected at a leading edge (64) and a trailing edge (66), forming a plurality of slots (82) in the pressure side of the airfoil extending towards the trailing edge, and extending a plurality of pins (150) arranged in rows between the airfoil suction and pressure sides, such that at each of a first row of pins (152) has a substantially elliptical cross-sectional area, wherein the first row of pins is between the remaining rows of pins and the airfoil pressure side slots.
