Abstract
An engine case is provided having a first solid wall region and a second solid wall region with an internal region between the first and second sold wall regions. The internal region defines at least one cavity. One or more lattice structures are provided within the cavity that controls the flow of coolant air through the cavity. The cavity may be divided into two or more distinct cooling regions for allowing particular coolant flow paths to be provided to different parts of the engine case.
