Compressor rotor blades, compressors, and methods for forming a compressor rotor blade profile

摘要

The invention relates to a compressor rotor blade for a compressor of an axial flow design with a blade profile having a transonic section and a profile section (21) of a blade profile, the profile section extending in the transonic section, Has convex suction side areas (11) arranged downstream of the concave suction side area (10) and concave suction side area (10) on the pressure side surface (5) And a concave pressure side area 13 arranged downstream of the convex pressure side area 14 so that the curvature progression 27 on the pressure side 4 of the profile section 21 and the suction side of the profile section 21 The positions of the minimum values of the curvature advances 27 and 28 are constant in each case and the positions of the minimum values of the curvature advances 27 and 28 are shown in the profile section 22 of the profile section 22. [ 10% of length And the positions of the maximum values of the curvature advances 27, 28 are different from one another by less than 10% of the length of the profile strings 22.
