A thermal barrier/cooling system for controlling a temperature of an outer case of a gas turbine engine. The thermal barrier/cooling system includes an internal insulating layer supported on an inner case surface, the internal insulating layer extending circumferentially along the inner case surface and providing a thermal resistance to radiated energy from structure located radially inwardly from the outer case. The thermal barrier/cooling system further includes a convective cooling channel defined by a panel structure located in radially spaced relation to an outer case surface of the outer case and extending around the circumference of the outer case surface. The convective cooling channel forms a flow path for an ambient air flow cooling the outer case surface. 1. A gas turbine engine comprising:an outer case defining a central longitudinal axis, and an outer case surface extending circumferentially around the central longitudinal axis; an internal insulating layer supported on an inner case surface opposite the outer case surface, the internal insulating layer extending circumferentially along the inner case surface and providing a thermal resistance to radiated energy from structure located radially inwardly from the outer case; and', 'a convective cooling channel defined by a panel structure located in radially spaced relation to the outer case surface and extending around the circumference of the outer case surface, the convective cooling channel is generally axially aligned with the internal insulating layer and forms a flow path for an ambient air flow cooling the outer case surface., 'a thermal barrier/cooling system for controlling a temperature of the outer case, the thermal barrier/cooling system including2. The gas turbine engine of claim 1 , wherein the convective cooling channel includes a cooling air supply inlet at a first circumferential location claim 1 , and an exhaust air outlet at a second circumferential location diametrically opposite from ...
