ABSTRACT:
An inlet plenum for coupling airflow from a radial airflow inlet to an axial compressor inlet for a compressor comprises a perforated inlet (PI) baffle that comprises a generally cylindrical baffle that circumscribes the compressor inlet and a plurality of apertures, each aperture perforating the baffle to pass the airflow from the radial airflow inlet to the compressor inlet and a plurality of stagnation vanes, each stagnation vane comprising a generally arc-shaped vane that extends proximate the PI baffle to establish an approximation of stagnant flow around the entire PI baffle to reduce flow distortion of the airflow between the radial airflow inlet and the axial compressor inlet.
