    Abstract: A component for a gas turbine engine. The component includes a body. The body has an exterior surface abutting a flowpath for the flow of a hot combustion gas through the gas turbine engine. Further, the body defines a cooling passageway within the body to supply cool air to the component. The component includes a leading face and a trailing face defining a trench therebetween on the exterior surface. The body defines a plurality of cooling holes extending between the cooling passageway and a plurality of outlets defined in the trench such that the trench is fluidly coupled to the cooling passageway. Additionally, the leading face and trailing face are each tangent to at least one of the plurality of outlets. The trench directs the cool air along a contour of the component.

    Abstract: An airfoil for a turbine engine having a working airflow separated into a cooling airflow and a combustion airflow, the airfoil comprising a wall defining an interior and having an outer surface over which flows the combustion airflow, the outer surface defining a first side and a second side extending between a leading edge and a trailing edge to define a chord-wise direction; at least one cooling conduit located within the interior and fluidly coupled to the cooling airflow. A primary cooling passage having at least one inlet fluidly coupled to the at least one cooling conduit, a primary outlet on the outer surface. A passage connecting the at least one inlet to the primary outlet, the passage separated into a first portion and a second portion. The primary outlet spaced from the trailing edge a predetermined distance.

    Abstract: A method of forming a mated component pair includes forming a first geometry on a first mating surface of a first component and a complementary second geometry on a second mating surface of a second component. The first geometry and the second geometry can be determined from a geometric key associated with a component identifier, e.g., by inputting the geometric key into a mathematical algorithm or random number generator. When a replacement for the second component is needed, the component identifier may be obtained from the first component, the component identifier may be used to obtain the geometric key, and the geometric key may then be used to determine the second geometry. The second geometry may then be formed on the second component such the second component may properly mate with the mated first component.
