| 20120056435 | WIND TURBINE AND A DIRECT-DRIVE GENERATOR - A wind turbine of the horizontal axis, direct-drive type, comprises a hub provided with one or more blades, a generator with a centerline that is technically horizontal, the generator comprising an inner rotor which is driven by the hub and an outer stator, the stator comprising a front plate, a back plate and stacked, arcuate laminates. The front plate and the back plate are connected by tension rods so as to form a stator unit with the stacked, arcuate laminates being sandwiched between the back plate and the front-plate under compression, the arcuate laminates having protrusions over the circumference of the stator for dissipating heat to the atmosphere. The invention also relates to a direct-drive generator. | 03-08-2012 |
| 20120043763 | OFFSHORE WIND PARK - Wind farm comprising at least one buoyant structure having two corners provided with a wind turbine and a third corner comprising a mooring section, e.g., with a disconnectable mooring turret. The third corner does not carry one of the wind turbines. Shared facilities for the two wind turbines, such as a helideck and/or electrical equipment, such as a converter and/or transformer, can be located on or near the third corner. | 02-23-2012 |
| 20120034094 | PROTECTED WIND TURBINE BLADE, A METHOD OF MANUFACTURING IT AND A WIND TURBINE - A protected turbine blade includes a first turbine blade shell and a second turbine blade shell, being fibre-reinforced, are connected by a cured resin and provided with a protective cover at a leading edge. The protective cover is a composite comprising a layer of UV-resistant thermoplastic material and a layer of cured epoxy resin, the UV-resistant thermoplastic material having the following properties a surface free energy of less than 35 mJ/m | 02-09-2012 |
| 20110304149 | WIND TURBINE COMPRISING A COOLING CIRCUIT - Wind turbine comprising a tower with an interior enclosed by a tower wall which forms a heat exchange surface in an air cooling circuit wherein the tower interior forms a channel for guiding hot air along a flow path, wherein one or more air flow deflectors are arranged within the flow path for guiding the flow towards the tower wall. The flow deflectors can for example be active flow deflectors, such as fans or blowers, or passive flow deflectors, such as one or more static flow deflector plates or vanes, forming a static mixer element. | 12-15-2011 |
| 20110200427 | WINDTURBINE COMPRISING A BEARING SEAL - Wind turbine provided with a bearing supporting a hub carrying rotor blades, the bearing comprising a rotational bearing race connected to the hub and a stationary bearing race, a lubrication area between the bearing races which area is confined at both ends by first seal rings sealing the gap between the rotational bearing race and stationary parts to form a lubrication barrier. At one or both ends of the lubrication area a redundant seal ring is arranged at a distance from the first seal ring in or near the gap to be sealed. | 08-18-2011 |
| 20110116935 | METHOD OF MANUFACTURING A TURBINE BLADE HALF, A TURBINE BLADE HALF, A METHOD OF MANUFACTURING A TURBINE BLADE, AND A TURBINE BLADE - An aspect of the invention relates to a method of producing a turbine blade half using resin infusion molding. The method includes providing a mold for a turbine blade shell with fiber mats, placing a strengthening member over the fiber mats in the mould; placing a air-impermeable sealing layer over the fiber mats and against the strengthening member; introducing a curable resin in the fiber mats under reduced pressure, including in the area below the strengthening member; and curing the resin to form a turbine blade half, said turbine blade half comprising a turbine blade shell attached to the strengthening member. An aspect of the invention also relates to a turbine blade half, a method of producing a turbine blade, and to a turbine blade. | 05-19-2011 |
