This patent describes a gas turbine engine. It comprises: a rotary compressor, a radial flow turbine wheel coupled to the compressor, an annular combustor having a radially inner wall and a conical wall extending axially toward the turbine wheel and radially outwardly from the inner wall and being connected thereto and terminating in an outlet, a nozzle surrounding the turbine wheel and connected to the outlet, a compressed air plenum connected to the compressor and generally surrounding the combustor and terminating in a rear turbine shroud adjacent the turbine wheel and spaced from the conical wall to define a cooling air passage between the inner wall and the conical wall on the one had and the plenum and the rear turbine shroud on the other and opening to a location in the vicinity of the nozzle, and structure of non-uniform shape on the surface of the rear shroud remote from the turbine wheel and facing the passage, the improvement wherein the engine is characterized by: the presence of means defining an interconnecting wall of smoothly curved shape joining the inner wall and the conical wall for causing a cooling air stream in the passage to attach itself to the interconnecting and conical walls; and the absence of any aerodynamically smooth cover for the rear shroud and the structure of non-uniform shape thereon.
