COMPRESSOR BLADE AND PRODUCTION AND USE OF A COMPRESSOR BLADE

摘要

The invention relates to a compressor blade (50) of a compressor (9), which, along a main axis (53), comprises a blade base (55), a platform area (59) and an adjacent blade profile (61) having a profile tip. Said blade profile (61) is configured by a convex wall (69) at the suction end and a concave wall (67) at the pressure end opposite the wall (69) at the suction end. These surfaces extend, with respect to a flow medium, from a leading edge (63) to a trailing edge (65), a profile center line (71) extending in the center between the two. A front face (73) is arranged on the profile tip (72) at an angle to the main axis (53), a sealing lip (75) at least partially extending from the leading edge (63) to the trailing edge (65) and the blade profile (61) including the sealing lip (75) having a blade profile height (H) extending in the direction of the main axis (53). 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 (HL) of the sealing lip (75) is less than 2 percent of the height (H) of the blade profile (61).
