CENTRIFUGAL COMPRESSOR IMPELLER WITH BLADES HAVING AN S-SHAPED TRAILING EDGE

摘要

The centrifugal compressor impeller comprises an inlet, an outlet and a disk extending from the inlet to the outlet. A plurality of blades extend from the disk, each blade having a leading edge at the inlet, a trailing edge at the outlet, a blade base extending along the disk between the leading edge and the trailing edge, and a blade tip extending between the leading edge and the trailing edge opposite the disk. The trailing edge is S-shaped with an intermediate inflection.
