A turbine includes three rows of airfoils which receive in sequence hot combustion gases during operation. The third row airfoils are clocked circumferentially relative to the first row airfoils 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.

1. A method for cooling a third row of turbine airfoils following in sequence first and second rows of turbine airfoils in a gas turbine engine, comprising:selecting the hottest running condition of said engine for producing the hottest temperature combustion gases which flow in sequence through said three rows; and clocking said third row airfoils circumferentially relative to said first row airfoils at said running condition for bathing said third row airfoils with wakes discharged from said first row airfoils for cooling said third row airfoils.
