Abstract: A gas turbine engine component assembly including: a first component having a first surface and a second surface opposite the first surface; a second component having a first surface and a second surface opposite the first surface of the second component; and a cooling circuit formed in the second component, the cooling circuit including an inlet at the second surface of the second component, an outlet at the first surface of the second component, an inward surface, and an outward surface, the inward surface and the outward surface being in a facing spaced relationship extending from the inlet to the outlet defining an airflow passageway therebetween, wherein the airflow passageway includes a parallel portion that is oriented about parallel to at least one of the first surface of the second component and the second surface of the second component.

Abstract: A heat exchanger for a gas turbine engine including: a heat exchanger core having an inlet, an outlet, and a fluid passageway; an inlet pipe configured to provide hot airflow to the inlet; and an inlet flow conditioner fluidly connecting the outlet of the inlet pipe to the inlet of the heat exchanger core, the inlet flow conditioner including: a central attachment body; an outer shell located radially outward from the central attachment body, the outer shell including an inlet connected to the outlet of the inlet pipe, and an outlet opposite the inlet and connected to the inlet of the heat exchanger core; and a plurality of guide vanes extending from the central attachment body to the outer shell, the plurality of guide vanes being configured to impart a swirl upon airflow entering the inlet of the inlet flow conditioner and exiting the outlet of the inlet flow conditioner.

Abstract: In a featured embodiment, a heat exchanger assembly includes an inlet manifold defining an expanding area in a direction of flow; and an inlet in flow communication with the inlet manifold, the inlet including a wall for inducing a rotational inertia to flow entering the inlet manifold.
