Abstract (en)
[origin: WO2017137201A1] The invention relates to compressor rotor blade for an axial-type compressor having a blade profile having a transsonic section and has a profile section (21) of the blade profile which extends in the transonic section and which has a concave suction-side region (10) and a convex suction-side region (11) on the suction side (5) of said profile section, the convex suction-side region being arranged downstream of the concave suction-side region (10), and which has a convex pressure-side region (14) and a concave pressure-side region (13) on the pressure side (4) of said profile section, the concave pressure-side region being arranged downstream of the convex pressure-side region (14), wherein a curvature progression (27) on the pressure side (4) of the profile section (21) and a curvature progression (28) on the suction side (5) of the profile section (21) are both applied in a continuous manner over a profile chord (22) of the profile section (21), the positions of the minimum values of the curvature progressions (27, 28) deviate from each other by not more than 10% of the length of the profile chord (22), and the positions of the maximum values of the curvature progressions (27, 28) deviate from each other by not more than 10% of the length of the profile chord (22).
