Abstract: Provided is a beacon illumination device for signaling the presence of a wind turbine to aircraft, including an illuminator device having at least one light-emitting diode, at least one beacon light that can be mounted on an end part of the wind turbine at a distance from the illuminator device, at least one light conductor having optical fibers for transmitting light from the illuminator device to the beacon light, with the optical fibers being grouped in at least one bundle of optical fibers, with the illuminator device also having an optical collimator with at least one collimator lens disposed between the light inlet of the optical fibers and the light-emitting diode, for converting scattered light emitted by the light-emitting diode into a parallel beam of light and transmitting same towards the light inlet of the optical fibers.

Abstract: A thermal conditioning system for an off-shore wind turbine. The thermal conditioning system has an insulating structure that reduces the thermal losses by convection of treated air circulating through a duct inside the tower, from the base-level of the wind turbine to the nacelle structure. The treated air is supplied by an air-treatment system located at the base level of the wind turbine. In the insulating structure an insulating material of a greater thermal conductivity than the treated air is provided, and a plurality of voids is arranged between the insulating material so that air flow between the voids is prevented by the insulating material.

Abstract: A segmented gear plate configured to be removably connected to a pitch bearing of a wind turbine has been described. The pitch bearing is present between a rotor hub and a plurality of blades. The pitch bearing axially pivots the plurality of blades between different pitch angles. The pitch bearing includes an inner bearing ring and an outer bearing ring rotatably interconnected to each other. The segmented gear plate is removably connected to at least one of the inner bearing ring or the outer bearing ring by at least one connecting element. The segmented gear plate having a plurality of gear teeth, the plurality of gear teeth configured to allow the rotation of a drive shaft of a motor to achieve different pitch angles.

Abstract: A method and system to prevent the equipment corrosion in an offshore wind turbine by minimizing the humid ambient air entry into the turbine. The method uses the fact that the ambient air entry into or the inside air leakage out of the turbine can be minimized by lowering the air pressure difference across the outside and inside faces of the seals. The proposed system includes a slotted, streamlined plenum over each of these interfaces that helps moderate the air pressure on the outside of the seals. On the inside, the air pressure over the seals is controlled by a variable air flow resistance system that consists of two circular, coaxial perforated plates that can rotate relative to each other.
