ジグザク冷却式のタービンブレード
Document Type and Number:
Japanese Patent JP4958527
Kind Code:
B2
Abstract:
A turbine airfoil (16) includes pressure and suction sidewalls (22,24) spaced apart to define flow channels (1-12) extending in span and separated by ribs (36). Side channels (1,3,5,8-10) are disposed along one sidewall (22,24) and spaced from the opposite sidewall (22,24) by the ribs (36), and a mid channel (2,4) bridges the sidewalls (22,24). The side and mid channels (1-5) are arranged in a zigzag serpentine cooling circuit alternating therebetween for transferring heat from the side wall (22,24) into the mid channel (2,4).
