Claim Text:
1. A turbine engine shutdown temperature control system for a gas turbine engine, comprising: a casing forming an outer structure surrounding at least one turbine component, the casing a first half coupled to a second half, the first and second halves of the casing being positioned on opposite sides of a centerline of the casing; one or more casing temperature control housings extending along an inner surface of the casing and at an upper side region of the casing, wherein the upper side region is positioned in the first half of the casing, thereby positioning each one of said one or more casing temperature control housings completely in the first half of the casing; wherein each of the one or more casing temperature control housings includes at least one exhaust slot extending through an outer wall forming the housing, wherein the at least one exhaust slot is in communication with a temperature control housing chamber contained within the casing temperature control housing; and wherein the at least one exhaust slot is configured to exhaust fluids from the temperature control housing chamber into the casing to isolate the upper side region of the casing from buoyancy effects of hot gases within the casing after shutdown of the gas turbine engine; and wherein each of the one or more casing temperature control housings is generally arc-shaped, being elongated along an arc-length extending partially circumferentially along the inner surface of the casing.
