Abstract: An engine component assembly is provided for impingement cooling including discrete cooling features. An insert is located opposite and adjacent to a cooled surface of the engine component and includes a plurality of angled impingement air holes. A cooling fluid flow path is flowing on one side the cooled surface of the engine component and adjacent to the insert and passes through the angled cooling holes of the insert in order to cool the cooled surface of the engine component. Additionally, a plurality of discrete cooling features may be located along the cooled surface of the engine component opposite the plurality of cooling holes in the insert.
