A turbo machine including a plenum is formed within a double wall structure including an opening configured to provide fluid communication of a first flow of fluid between the plenum through the double wall structure, and an outer wall forming a passage configured to receive a second flow of fluid separate from the first flow of fluid, wherein a flowpath structure is formed at least in part within an inner wall, the flowpath structure configured to receive a third flow of fluid therethrough, the third flow of fluid separate from the first flow of fluid, the flowpath structure comprising an exit opening configured to provide fluid communication from the flowpath structure to the flowpath.

Frame for a heat engine

A frame for a heat engine, the frame including an inner wall extended from an inlet end to an outlet end, the inner wall forming at least in part a core flowpath, the inner wall comprising a plenum formed between an outer portion of the inner wall and an inner portion of the inner wall, wherein a cavity is formed inward of the inner portion of the inner wall, and wherein the inner wall includes a first plenum opening providing fluid communication between the cavity and the plenum, and wherein the inner wall comprises a second plenum opening providing fluid communication between the plenum and the core flowpath.

A thermal management system for a heat engine, the system including an forming at least in part a core flowpath and a cavity, wherein the core flowpath and the cavity are separated by a double wall structure formed by at least a portion of inner wall, and wherein the double wall structure includes a plenum. A first opening provides fluid communication between the cavity and the plenum, and a second opening provides fluid communication between the plenum and the core flowpath. The inner wall is configured to receive a first flow of fluid. An outer wall forms a passage extended at least partially around the core flowpath. The outer wall is configured to receive a second flow of fluid fluidly separated from the core flowpath.

A sump housing apparatus for a gas turbine engine includes: an annular body; and a plurality of service tubes arrayed around the body, each service tube having a proximal end intersecting the body and an opposed distal end, each service tube having an inner port communicating with an interior of the body; wherein the body and at least one of the service tubes are part of a monolithic whole.
