    Abstract: An airfoil of a gas turbine engine having a hollow body defining at least one airfoil cavity therein, the hollow body defining an inner diameter and an outer diameter and a baffle positioned within the at least one airfoil cavity and extending over less than an entire length between the inner diameter and the outer diameter, the baffle configured to reduce the cross-sectional area within the at least one airfoil cavity. The at least one airfoil cavity includes a first portion having a length that is defined by an open cavity having a full cross-sectional area and a second portion having a length that is defined by a reduced cross-sectional area, the second portion being the length of the baffle within the at least one airfoil cavity.

    Abstract: A vane includes a forward rib and an aft rib positioned axially aft of the forward rib. The vane also includes a middle rib positioned axially between the forward rib and the aft rib, such that the forward rib and the middle rib define a forward passage configured to receive a forward baffle and the middle rib and the aft rib define an aft passage configured to receive an aft baffle. The vane also includes an inner surface extending axially from the forward rib to the aft rib, being radially separated from the middle rib via a gap such that air can flow between the aft passage and the forward passage via the gap, and having a radially outward curve from the forward rib to the middle rib and having a radially inward curve from the middle rib to the aft rib.

    Abstract: A gas turbine engine component includes a structure having a wall that provides an exterior surface. A first cooling passage is arranged adjacent to and interiorly of the wall. A second cooling passage is arranged in the wall and provides a first fluid flow direction. A resupply channel is arranged in the wall and is fluidly interconnected to the second cooling passage. A resupply hole fluidly interconnects the first cooling passage and the resupply channel. The resupply channel is transverse relative to the second cooling passage to provide a second fluid flow direction that extends from the resupply hole to the second cooling passage.
