Frame for a heat engine

A frame for a heat engine, the frame comprising:

• an inner wall at least partially forming a primary flowpath, the inner wall at least partially forming a flowpath structure within the inner wall, the flowpath structure configured to receive a flow of fluid therethrough, the flow of fluid in the flowpath structure separate from a flow of fluid through the primary flowpath, wherein the flowpath structure comprises an exit opening configured to provide fluid communication from the flowpath structure to the primary flowpath.

A turbo machine, the turbo machine forming a flowpath extended therethrough, the turbo machine comprising:

• a compressor section comprising a compressor vane and a compressor rotor;
• a frame positioned upstream of the compressor section, wherein the flowpath is extended through the frame and the compressor section, the frame comprising an internal flowpath structure, the flowpath structure configured to receive a flow of fluid therethrough, wherein the flowpath structure comprises an exit opening positioned within a radial span of the flowpath, the exit opening configured to provide the flow of fluid from the flowpath structure to the compressor section downstream of the exit opening at the frame.
