Stator blade for compressor, has shovel blade, which has form in cladding surface in direction perpendicularly to any place of shovel blade surface, where shovel blade has uncoated nominal profile

摘要

The stator blade (12) has a shovel blade (18), which has a form in a cladding surface within plus minus 2.54 millimeter in a direction perpendicularly to any place of the shovel blade surface. The shovel blade has an uncoated nominal profile in accordance with cartesian coordinate values X, Y, and Z. The values of the Z-coordinate are perpendicularly distanced from levels, which are right-angled to a radius of central line of a compressor (10). The Z-value begins at a radial aerodynamic section of the shovel blade in the XY-level with zero.
