Compressor blade and production and use of a compressor blade

摘要

The invention relates to a compressor blade of a compressor which, along a main axis, comprises a blade base, a platform area and an adjacent blade profile having a profile tip. The blade profile is configured by a convex wall at the suction end and a concave wall at the pressure end opposite the wall at the suction end. These surfaces extend, with respect to a flow medium, from a leading edge to a trailing edge, a profile center line extending in the center between the two. A front face is arranged on the profile tip at an angle to the main axis, a sealing lip at least partially extending from the leading edge to the trailing edge and the blade profile including the sealing lip having a blade profile height extending in the direction of the main axis. In order to allow for an inexpensive compressor blade having improved aerodynamic properties and a modified sealing lip while having the same sealing properties, the height of the sealing lip is less than 2 percent of the height of the blade profile.

主权项

1. A compressor blade for a compressor, comprising:
a blade root arranged along a main axis of the blade; a platform section arranged adjacent to the blade root and along the main axis; a blade profile adjoining the platform section having a profile tip and a profile height extending in the direction of the main axis, the blade profile extending from a leading edge with respect to a flow medium to a trailing edge between which a profile center line extends in the middle, and a convex suction side wall and a concave pressure side wall opposite the suction side wall, wherein an end face, which is disposed transversely to the main axis, is located on the profile tip; and a sealing lip arranged on the end face, the sealing lip being formed in one piece with the blade profile, extends along the profile center line at least partially from the leading edge to the trailing edge, at a distance from suction side wall and from pressure side wall, wherein the sealing lip has a sealing lip height that is less than two percent of the height of the blade profile.
