Abstract: A hinged connection apparatus is described for securing a first wind turbine component to a second. The first wind turbine component may be a wind turbine blade and the second wind turbine component may be a control surface such as an aileron. The first or second wind turbine component comprises at least one hinge housing (15) in which an electrically sensitive component, such as a cable or an electrical activated hinge pin, is retained. Preferably, the interior portion of the hinge housing (30) is made of a glass fibre composite material that is fatigue resistant and electrically non-conductive. The exterior (31) of the hinge housing on the other hand is preferably electrically conductive. Furthermore, an extendable conductive or non-conductive sleeve (32) may be provided to bridge the gap in-between one hinge housing and an adjacent hinge housing.

Abstract: A heat exchanger assembly for cooling a heat-generating component, such as a generator or power electronics module, within a wind turbine nacelle comprises a thermoelectric element, such as a Peltier element, having a first section arranged in a first region of relatively high temperature in contact with the heat-generating component or in the vicinity thereof, and a second section arranged in a second region of a relatively low temperature. The thermoelectric element is configured to transfer heat from the first region of relatively high temperature to the second region of relatively low temperature with consumption of electrical energy. A source of electrical energy is provided for the thermoelectric element, and a control unit may be provided for controlling the energy supply in order to control the temperature of the component or surface area cooled by the thermoelectric element. A further cooling element including a so-called heat pipe may be provided to enhance cooling efficiency.

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.
