<p>An air-cooled airfoil (10) whose surfaces adjacent its trailing edge (12) are not equally cooled in order to compensate for unequal heating of the pressure and suction walls (16,18) near the trailing edge. The airfoil (10) is formed to have a cooling passage (24) defined by and between the pressure and suction walls (16,18) at the airfoil trailing edge (12). The interior surface (30) of the suction wall (18) is formed to be substantially smooth and uninterrupted, while the interior surface (28) of the pressure wall (16) is formed to include surface features (34) that project into the cooling passage (24) to cause preferential convective cooling of the pressure wall (16) as compared to the suction wall (18) when air flows through the cooling passage (24).</p> |
