PROBLEM TO BE SOLVED: To provide a turbine nozzle for a gas turbine engine (10). SOLUTION: This turbine nozzle includes a nozzle segment (30) which has blade profile-shaped vanes (122) provided with vanes (122), roots (136), tips (138), front edges (132), rear edges (134) and bent positive pressure and negative pressure side faces (140, 142) opposing to each other. An arc inner band segment (146) is mounted on the roots (136) of the vanes (122). The inner band segment (146) includes an inner flow passage face (148) demarcated by a front face (150) and a rear face (152) in the front end part and the rear end part. A projecting bent blended corner part (154) is formed between the inner flow passage face (148) and the rear face (152). COPYRIGHT: (C)2007,JPO&INPIT |
