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.
Un canal d'admission servant au couplage du flux d'air de l'admission de la ventilation radiale à celui de l'entrée d'un compresseur axial comprend une chicane d'admission perforée normalement cylindrique, qui circonscrit l'entrée du compresseur, ainsi qu'un ensemble d'ouvertures, chacune de ces ouvertures perforant la chicane pour laisser passer l'air de l'admission de la ventilation radiale à l'entrée du compresseur. La chicane comporte également un ensemble d'aubes de stagnation normalement curvilignes qui vont rejoindre la chicane d'admission perforée afin d'établir une approximation d'air immobile autour de l'ensemble de la chicane et de réduire ainsi la distorsion du flux de l'air entre l'admission d'air de la ventilation radiale et l'entrée du compresseur axial.
