Abstract
The invention relates to a heavy-duty upgrading method for rotor blades of existing wind turbines and to a plastic membrane used in the method according to the invention, wherein the rotor blades are covered and/or extended in that at least one fibre-reinforced or fabric-reinforced plastic membrane is fitted onto an outer surface of the original aerodynamic profile of the rotor blade being upgraded and the original contour of the rotor blade being upgraded is then joined to the upgraded rotor blade.
Claims20
A method for strengthening rotor blades of existing wind turbines, comprising a cladding and/or extension of a profile of at least one rotor blade to be strengthened, wherein the cladding and/or extension is effected in that at least one fiber-reinforced or fabric-reinforced plastic membrane is matched to a shell surface of an original aerodynamic profile of the rotor blade to be strengthened and, following the original contour of the rotor blade to be strengthened, is connected to the rotor blade to be strengthened.
A plastic membrane for strengthening rotor blades of existing wind turbines, configured as a sock or tube, comprising a reinforcing fabric or scrim of high-tensile fibers, that is matched to the contour of the rotor blade to be strengthened, and that is coated with a polymer or embedded in a polymer matrix.
A strengthened rotor blade for a wind turbine comprising an aerodynamic profile, comprising a cladding and/or extension of the aerodynamic profile, configured as a strengthening measure, in the form of at least one fiber-reinforced or fabric-reinforced plastic membrane, which is matched to the shell surface of the aerodynamic profile and, following the original contour of the rotor blade, is connected to the rotor blade.
