Abstract
A gas turbine engine component comprising: a first component having a receiving aperture extending; a second component having a first surface and a second surface; and a passageway portion including a first end, a second end opposite the first end, and an outer surface extending from the second end to the first end, the passageway portion extending from the second surface of the second component through the receiving aperture of the first component, wherein the outer surface of the passageway portion and the first component define a gap therebetween, the gap fluidly connecting airflow in an airflow path proximate the second surface of the first component to the cooling channel, wherein the gap is configured to direct the airflow along the outer surface and the outer surface is shaped to redirect the airflow in a lateral direction parallel to the second surface such that a lateral airflow is generated.
