Title:
時計方向にずらしたタービン翼形部の冷却
Document Type and Number:
Japanese Patent JP4733876
Kind Code:
B2
Abstract:
A turbine (16) includes three rows of airfoils (22 -28) which receive in sequence hot combustion gases during operation. The third row airfoils (26, 28) are clocked circumferentially relative to the first row airfoils (22, 24) for bathing the third row airfoils with relatively cool wakes discharged from the first row airfoils during the hottest running condition of the gas turbine engine being powered. The third row airfoils therefore avoid the hottest temperature of the combustion gases for reducing the cooling requirements thereof.
