Definitions

  • the root area should be as close as possible to the neutral fiber 11 of the rotor blade 1 with regard to the main bending modes.
  • the stress on the roots is not decisive and does not limit the strength.
  • the weld seam is advantageously positioned here so that it is close to neutral fiber 11, so that shear stresses of the main eigenmode can be tolerated well.
  • the rotor blade 1 is essentially identical to the rotor blade according to FIG.
  • the rotor blade 1 comprises a special erosion protection measure 12 in the blade area 3 on the blade edge.
  • the erosion protection measure 12 can be implemented by different measures.
  • One possibility is the application of, for example, welding, welding, surfacing or plating of an erosion-resistant material, e.g. titanium or nickel materials with a buffer layer (if necessary), another possibility is hard material coating with an erosion-resistant material and a third possibility is surface hardening in areas exposed to erosion.
