Embodiment Construction

[0031] The invention here relates to a rotor-side rotor blade for an axial compressor for industrial use, in particular a static axial compressor.

[0032] figure 1 A schematic view of a rotor blade 10 according to the invention is shown, comprising a blade root 11 , a blade leaf 12 and a platform 13 positioned between the blade root 11 and the blade leaf 12 . Via the blade root 11 , the rotor blade 10 can be fixed on the rotor base body of the rotor of the axial compressor. The blades 12 have a blade profile for flow deflection.

[0033] The blade 12 of the rotor blade 10 has a flow entry edge 14 , a flow exit edge 15 , a pressure side 16 extending between the flow entry edge 14 and the flow exit edge 15 , and also between the flow entry edge 14 and the flow exit edge 15 . A suction side 17 extends between the edges 15 . The flow entry edge 14, flow exit edge 15, pressure side 16 and suction side 17 of the blade blade 12 together define a blade profile of the blade blade 1...

Abstract

A rotor blade of an axial compressor includes: a blade root; and a blade leaf. The blade leaf has: a flow inlet edge, a flow outlet edge, a pressure side extending between the flow inlet edge and the flow outlet edge and a suction side extending between the flow inlet edge and the flow outlet edge, which together define a blade profile of the blade leaf in Cartesian coordinate values x, y and z such that first and second profile coordinates, or the coordinates x and y when joining via continuous arcs, each describe a smooth profile section on a radial section height along a third profile coordinate, or the coordinate value z, and the joining of the radial profile sections with a smoothing function describe the blade profile of the blade leaf.

Description

technical field [0001] The invention relates to a rotor blade according to the preamble of claim 1 or according to the preamble of claim 4 or according to the preamble of claim 5 . Background technique [0002] Axial compressors typically have a plurality of compressor stages, wherein each compressor stage includes a rotor-side rotor-side rotor blade rim and a stator-side vane vane rim ( Leitschaufelkranz). The rotor-side rotor blades have a blade root and a blade leaf, wherein the rotor blade is fastenable via its blade root to the rotor base body of the rotor, and wherein the blade blade has a blade profile for flow deflection. The blade profile of the rotor blade consists of a flow-in edge, a flow-out edge, a pressure side of the blade extending between the flow-in edge and the flow-out edge and also between the flow-in edge and the flow-out edge defined by the suction side extending between them. Here, the blade contour of a blade is typically defined by Cartesian coo...
