Abstract
An engine includes a housing having a single wall, where the wall has a rib and a flange, and the wall provides a primary structure and cooling for the engine. A closeout is attached to an outer surface of the wall, and the closeout and the wall form a cavity. The closeout provides a secondary structure for containing a coolant fluid flow within the cavity. The closeout may be corrugated, and the ribs may be exposed to the cavity.
