Abstract
Gas turbine engine components having an airfoil extending outwardly of a platform are mounted in adjacent relationship, and such that cooling air flows outwardly of a gap between mating faces of the platforms. The location of localized hot spots is identified on the platform, and the mating faces are designed to provide cooling air through the gap to address these hot spots. A suction side edge of the platform has a curved portion extending inwardly into the platform, and the pressure side has a curved portion bulging outwardly away from the airfoil. When these two portions on adjacent components mate, a gap is provided between two platforms that provides leakage cooling air to the hot spot.
