Abstract:
The invention relates to a bearing arrangement (10) for supporting a shaft (16) of a device for extracting energy from a water current (14), wherein the bearing arrangement comprises at least one radial sliding bearing (18) and at least one axial sliding bearing (20, 22), and wherein the bearing arrangement can be lubricated by water penetrating from the outside.
Abstract:
The invention provides a wind turbine component having an exposed surface made of a hydrophobic material and having a surface texture providing a Water Contact Angle (CA) of at least 150. Due to the combination between a CA over 150 and the hydrophobic material, the component becomes less vulnerable to ice formation etc. The invention further provides a method of preventing ice formation, a method of reducing noise and a blade for reducing noise from a wind turbine.
