An air-cooled airfoil whose surfaces adjacent its trailing edge are not equally cooled in order to compensate for unequal heating of the pressure and suction walls near the trailing edge. The airfoil is formed to have a cooling passage defined by and between the pressure and suction walls at the airfoil trailing edge. The interior surface of the suction wall is formed to be substantially smooth and uninterrupted, while the interior surface of the pressure wall is formed to include surface features that project into the cooling passage to cause preferential convective cooling of the pressure wall as compared to the suction wall when air flows through the cooling passage.
