Abstract: A gas turbine engine component includes a body having an internal cooling passage with opposed walls and an array of heat transfer members attached to at least one of the opposed walls each with at least one fillet. There is an airflow direction through the cooling cavity such that the heat transfer members have a leading edge and a trailing edge. The at least one fillets have a leading edge and a trailing edge. A fillet portion leading edge is asymmetric relative to a fillet portion trailing edge to control an air flow direction towards downstream ones of the heat transfer members in the array. A gas turbine engine is also disclosed.

Abstract: An airfoil for a gas turbine engine is disclosed. In various embodiments, the airfoil includes a cooling passage; an outer wall separating a core flow path from the cooling passage; a diffuser in fluid communication with the cooling passage and opening into the core flow path, the diffuser being characterized by a linear ridge on a downstream end of the diffuser; and a thermal barrier coating covering the outer wall and the linear ridge.

Abstract: A casting plug for a vane of a gas turbine engine includes a plug body a flow control feature and a support that extends between the plug body and the flow control feature.

Abstract: An airfoil includes an airfoil body that has a peripheral wall that defines an exterior side and an interior side that bounds an internal cavity in the airfoil body. The peripheral wall has first and second wall sections joined by a transition section. The first wall section is thicker than the second wall section. The transition section provides a change in thickness between the first wall section and the second wall section. The second wall section includes a cooling hole that has a first end that opens to the internal cavity at the interior side and a second end that opens to the exterior side.
