Abstract
A component for a turbine engine includes a body with an exterior surface abutting a combustion flowpath for a combustion gas flow through the turbine engine, a cooling passage defined within the body, and a trench on the exterior surface. The trench includes a plurality of outlets, and a plurality of cooling holes extending from the cooling passage to the corresponding plurality of outlets.
Claims20
A component for a turbine engine, comprising:
- a body with an exterior surface abutting a combustion flowpath for a combustion gas flow through the turbine engine;
- a cooling passage defined within the body and supplying cooling air to the component;
- and
- a trench on the exterior surface, comprising:
- an undulating surface defining a minimum depth and a maximum depth of the trench with respect to the exterior surface;
- a plurality of outlets in the undulating surface;
- and
- a plurality of cooling holes extending from the cooling passage to the corresponding plurality of outlets;
- wherein the undulating surface comprises a curved surface defining a cooling wall between two adjacent outlets in the plurality of outlets,
- wherein at least one outlet in the plurality of outlets is located at the maximum depth of the trench;
- and
- wherein at least one cooling hole in the plurality of cooling holes comprises a cross-sectional area that increases in a direction toward the plurality of outlets.
