Abstract

In order to form a stable leading-edge vortex (3), the oblique leading edge (1) of the axial compressor vane (11) is scarfed. As a result, the uncontrolled breakaway of the flow at the leading edges (1) of the vanes (11) is avoided and shifted into a region with very small intake volumes.
