Definitions

  • the present invention relates to a wind turbine rotor blade suitable for a wind turbine, said wind turbine rotor blade having a length extending from a first end, e.g. a root end, to a second end, e.g. a tip end, said wind turbine rotor blade further comprises a leading edge and a trailing edge, where a pressure side and a suction side extend between said leading edge and trailing edge and thus defines an airfoil shaped cross section, where said leading edge comprises a leading edge protection area along at least a part of said length of the wind turbine rotor blade, where a leading edge protection means is provided in said leading edge protection area, said protection means comprises a protective layer having a first surface facing against the leading edge and a second surface facing away from the leading edge, said first surface is attached to the leading edge protection area.
  • the tip speed of wind turbines has increased.
  • the old and smaller wind turbines typically had tip speeds about 60 m/s.
  • the new and larger turbines run typically at tip speeds about 80-90 m/s.
  • Wind turbine blades often suffer from leading edge erosion after a few years opera- tion.
  • the erosion is mainly caused by fatigue in the leading edge protection coating or tape.
  • the leading edge has a relatively stiff structure underneath the protection coating or tape.
  • the fatigue damage occurs primarily because of rain drops hitting the leading edge blade surface at very high speeds.
  • the impact causes very large stresses in the coating, and after a period of 1-4 years, the coating is fatigued, and fall off.
  • the cost of wind turbines can be reduced by increasing the blade tip speed. That is the main reason why blade tip speeds have increased. In not-noise sensitive areas like mountain or offshore sites, the tip speed could be increased more, and thereby the cost of the wind turbines could be reduced more, if a safe solution is found to solve the current erosion problems.
  • 3M developed an anti-erosion polyurethane tape for helicopters 20 or 30 years ago. This tape has been used at wind turbine blades for 15 years or more, and it is still commonly used on many new blades every day. This is still considered the best or one of the best solutions at the market, although it can only withstand the water hammer effect for a few years in areas with heavy rain like a monsoon area.
  • WO 2103/092211 Aldescribes a wind turbine rotor blade suitable for a wind turbine with the construction described in the opening clause.
  • This document describes that, in the leading edge protection area, an adhesive layer is provided between a first surface of the protective layer and the original blade leading edge. The document does not describe hat a space can be formed between the original blade leading edge and the first surface of the protective layer in the leading edge protection area.
  • the protective layer is intended to rupture and to be detached from the blade.
  • the protective layer is not intended to last for the lifetime of the turbine.
  • said first surface of the protective layer comprises a first and a second edge area for attachment, e.g. by adhering, to a first attachment area on the pressure side and a second attachment area on the suction side of said wind turbine rotor blade and that a space is formed between the original blade leading edge in the leading edge protection area and the first surface of the protective layer.
  • leading edge protection means as an anti-erosion shield consisting of a very flexible thin shell which can spread out the elastic wave, the fatigue loads in the coating or tape are reduced, resulting in longer lifetime of the leading edge protection.
  • the invention is a leading edge protection means to be mounted on the existing blade leading edges that have lower stiffness, damping and weight.
  • An air gap or a light foam (ex. a 60 kg/m3 PVC foam) should separate the leading edge from the leading edge protection means.
  • a 60 kg/m3 PVC foam ex. a 60 kg/m3 PVC foam
  • the leading edge protection means consists of a glass/epoxy laminate at 1.5 mm thickness and a +/- 45 degree fiber orientation.
  • the leading edge protection means is painted with a good quality, relatively soft, anti- erosion coating, ex. Mankiewicz LEP9.
  • the leading edge protection means may be bonded to the blade about 50-100 mm chord wise direction from the leading edge, leaving an airspace of 1-2 mm between the leading edge of the blade and the inner surface of the anti-erosion shield.
  • the leading edge protection means can be made from any material that can dissipate the energy from the impacts from rain drops, hail and other objects in the incoming air.
  • Glass fiber epoxy is good, because it has good fatigue properties and low damping properties. It should be relatively thin to achieve a light and flexible leading edge pro- tection means.
  • the coating can be any coating that has a good resistance to water erosion. It does not need to be a coating. It could also be a tape, similar to the 3M anti-erosion tape, commonly used for wind turbine blades, and originally developed to protect helicopter blades from sand erosion.
  • the wind turbine rotor blade is peculiar in that the protective layer is attached to the leading edge protection area, which is provided as an original leading edge surface of the wind turbine rotor blade and which is not provided with recesses or the like to adapt to the protective layer within the wind turbine rotor blade.
  • the wind turbine rotor blade is peculiar in that the protective layer is a flexible membrane.
  • the protective layer is a flexible membrane.
  • the wind turbine rotor blade is peculiar in that the flexible membrane is made of a glass/epoxy laminate, e.g. with a +1-45 degree fibre orientation and has a thickness in the range 1 to 2 mm, preferably around 1,5 mm.
  • the wind turbine rotor blade is peculiar in that the flexible membrane is painted with a soft anti-erosion coating.
  • the wind turbine rotor blade is peculiar in that the protective layer comprises a third and a fourth edge area for attachment, e.g. by adhering, to a third and a fourth attachment area on the wind turbine rotor blade, and that the third and fourth edge areas connect the first and a second edge areas so that the space is a closed space.
  • the protective layer forms a closed space
  • a space which is solely filled with air or partly filled with air and a flexible foam material.
  • the leading edge will have a structure underneath the protective layer which is yielding.
  • Such construction which is not stiff, contributes to an efficient spreading of the elastic wave.
  • the fatigue loads are reduced.
  • the wind turbine rotor blade is peculiar in that the space is an air-filled space e.g. as one single room or divided into a number of rooms or alternatively as a space.
  • the space may contain light structures e.g. a PVC foam.
  • the space is filled by air as one single room or divided into a number of rooms.
  • the space could contain any other light foam structure which provides a number of air-filled rooms.
  • the important thing is to have a construction which reduces the stiffness and establishes a more yielding leading edge surface.
  • the wind turbine rotor blade is peculiar in that the light structure have a density between 40 and 80 kg/m3, preferably around 60 kg/m3.
  • the protective layer may be attached to the original leading edge surface of the wind turbine rotor blade by adhering.
  • the protective layer is adhered to the wind turbine rotor blade. Any suitable glue could be used. It is also possible to establish a mechanical attachment between the protective layer and the wind turbine rotor blade. However, gluing is preferred.

  • the wind turbine rotor blade is peculiar in that the space has a thickness between 1 and 2 mm between the leading edge and the first surface.
  • the wind turbine rotor blade is peculiar in that the density of a glue joint at the leading edge of the wind turbine rotor blade is less than 2000 kg/m 3 (2 g/cm 3 ), preferably less than 1000 kg/m 3 (l g/cm 3 ), said glue joint comprises the glue layer and the part of the two shells which are arranged opposite each other at each side of the glue layer.
  • the wind turbine rotor blade is peculiar in that the glue joint comprises the glue layer and the overlaying composite layers of the wind turbine rotor blade at such glue layer.
  • the wind turbine rotor blade is peculiar in that the glue joint does not comprise the protective layer.
  • the protective layer is not a part of the calculation of the density of the glue joint at the leading edge. Accordingly it is the original leading edge of the wind turbine rotor blade which is used for the calculation of the density.
  • the protective layer could have four attachment areas such that the space between the protective layer and the leading edge is a closed space.
  • the space may also be open between the first and the second edge areas of the protective layer.
  • the protective layer could have an end part in the direction of the root of the blade which is cut off perpendicular to the longitudinal direction and thus is sharp-edged, and the space in the end area could be filled with glue.
  • this end part could be gradually reduced in size and be glued to the leading edge of the wind turbine blade. In this way the outermost part of the protective layer would be in close contact with the leading edge of the blade.
  • the gradual reduction is especially important at the tip of the blade seeing that this is the area where the erosion mainly occurs. Accordingly the structure at the end of the protective layer facing the tip is important.
  • the protective layer facing the tip it is possible to use a sandwich foam which has been painted with a flexible anti-erosion coating. This way the end of the space is closed. However, the anti-erosion effect of the protective layer is maintained.
  • the end part of the space facing the tip could be open. This way it is possible for water to leave the space. In some situations this may give rise to problems with dirt which could be accumulated in the space.
  • the end part of the space facing the tip could also be glued and gradually reduced.
  • a new small section of a protective layer could be applied over the open end of the protective layer, and this section could have an open end. Accordingly only a very small part of the space would have problems with accumulation of dirt.
  • the space When forming the protective layer, which forms a space, it is also desired to provide the space with drain holes. It is preferred that the drain holes are provided at the leading edge of the blade, whereby the water may be drained into the blade. This way it is possible to have rather large drain holes, which would not have the risk of being stopped by accumulated dirt. Often a standard ring has drain holes in the area close to the tip. It is believed that the drain holes could be circular and have a diameter between 4 and 8 preferably approximately 6 mm.
