  • VARIABLE DIFFUSER WITH AXIALLY TRANSLATING END WALL FOR A CENTRIFUGAL COMPRESSOR
    Publication number: 20180340549
    Abstract: A variable diffuser for a centrifugal compressor comprises a passage between opposing disc faces and a plurality of vanes extending therethrough with a fixed angle relative to the engine centerline. Axial displacement between the opposing disc faces is variable. The vanes extend through one of the opposing disc faces as that disc face is axially translated.
