Abstract
A plenum () in a gas turbine engine mid-frame section () comprises one or more annular flow splitters () spaced from an inboard annular wall () that partition air flow flowing from a compressor into two or more portions of flow having different vectors. This provides for an improved balancing between supplying air to compression chamber intakes more directly and to transitions to aid in convective cooling. When an annular diffuser () is spaced between the compressor and the plenum (), the flow splitters () may provide an additional diffusion action. When no annular diffuser is so provided, the flow splitters () are effective to diffuse the air flow. Embodiments include those in which an annular diffuser () is relatively shorter and there is a longer axial expanse in the plenum () for flow splitters ().
