Abstract
An actively cooled component can be an airfoil, such as an air foil in a jet turbine engine. The component may have a body comprising at least one internal channel adapted for a flow of a cooling media therein. The channel may have two side walls separating a cold inner surface and a hot inner surface. The cold inner surface may have two impingement holes in fluid communication with a cooling media source, allowing for ingress of the cooling media into the internal channel. The hot inner surface may have one angled film hole in fluid communication with a hot outer surface, allowing for egress of the cooling media out of the internal channel. The first and second side walls may enclose a length of the internal channel along which the angled film hole is located between the two impingement holes.
