Abstract
An impingement cooling system for a gas turbine engine includes an initial impingement surface () with a centrally located opening (). A plurality of channels () and plurality of sub-channels () extends radially outward from the opening () and are formed by a plurality of fixtures () and plurality of sub-fixtures () that each separates each adjacent channel () and sub-channel () respectively. The plurality of fixtures () and plurality of sub-fixtures () each have a rounded upstream end () in a plane parallel relative to the initial impingement surface (). The plurality of fixtures () and the plurality of sub-fixtures () each have a concave shape along a middle portion () of the fixture () and sub-fixture () along an axis perpendicular to the initial impingement surface (). The plurality of channels () is divided into the plurality of sub-channels () extending radially outward of an inlet of each channel () from a stagnation point () created in the channel at an upstream end () of the sub-fixture ().
