Title:
内側寄り冷却式ノズルダブレット
Document Type and Number:
Japanese Patent JP4658584
Kind Code:
B2
Abstract:
A turbine nozzle (16) includes outer and inner bands (18, 20) integrally joined to a doublet of hollow vanes (22, 24) extending radially therebetween. Each of the vanes includes opposite pressure and suction sidewalls (28-34) extending between opposite leading and trailing edges, and spaced apart to define an internal plenum (40) extending radially between the bands for receiving an air coolant (12). The vanes are spaced apart from each other to define a flow passage (42) for channeling hot combustion gases (14) which are bound by corresponding pressure and suction sidewalls (28, 34) of the vanes facing inboard toward each other, with the remaining suction and pressure sidewalls (30, 32) of the vanes facing outboard. The vanes include different cooling configurations to bias more of the coolant to the inboard sidewalls (28, 34) than to the outboard sidewalls (30, 32).
