<p>The assembly (1) has a set of air inlet channels (3, 4) that is coupled to two air compression stages (13, 15) via diffusers (5, 6). A pre-rotation grid (12) is positioned in another set of air inlet channels (4a, 4r), where the grid is coupled to one compression stage comprising a compressor wheel (31) that is associated with a diffuser joint. The joint is coupled to a compression stage of a centrifugal compressor via an air return channel (14) that is inclined upstream (A).</p> |
