Modular annular heat exchanger

摘要: An annular duct including a modular heat exchanger for gas turbine engine is provided, where the includes plurality of radial modules in circumferentially adjacent arrangement. Each module cooled fluid inlet plenum segment, blades, and outlet segment. The blades configured arrangement defines an angular space that conformal between each blade. segment are serial axial flow define internal flowpath external cooling parallel to flowpath. further inner ring outer blade retainers. retainers axial, radial, circumferential position
