AXIAL CENTRIFUGAL COMPRESSOR WITH SCALABLE RAKE ANGLE

摘要

Mobile wheel for centrifugal or axial-centrifugal turbomachine compressor, comprising a base (2) on which are fixed by their foot (6) a plurality of blades (3) extending between a leading edge (8) and a trailing edge (9), said trailing edge being inclined at the level of the foot (6) of the blade (3) of a slope angle .alpha. by the meridian plane that passes through it in its foot, in the direction of rotation of said compressor (1), characterized in that the edge of leak (9) present at the head (7) of the blade (3) a slope angle .beta. less than its slope angle at the bottom of the blade.
