Abstract
Gas turbine engines include a compressor section configured to compress a core flow and a combustor section having a combustor that is arranged downstream from the compressor section along a path of the core flow. A turbine section is arranged downstream from the combustor along the path of the core flow, and includes a plurality of first vanes arranged at an outlet of the combustor, with at least one first vane of the plurality of first vanes having an internal vane path. A compressor diffuser is arranged to direct the core flow from the compressor section through the internal vane path. The path of the core flow, in a flow direction, passes through the compressor section, the compressor diffuser, the internal vane path, the combustor, and then between the first vanes of the plurality of first vanes to enter the turbine section.
