The system is specially developed to prevent the wear at the pitch and/or yaw gear tooth systems from the wind turbines but it could be used in others gears applications. Partners to further develop the system and/ or to establish commercial agreements along with technical cooperation are sought.
Universitat Politècnica de Catalunya - UPC posted this:Precast concrete floating platform to support Off-shore deep sea wind turbinesA new system including the design of the platform and erection process has been developed to produce economical and high-reliable floating support to offshore wind turbines in deep sea waters. A prestressed concrete structure built in a dry-dock, which includes both the floater and the tower is towed to the final position, where it is erected in a simple operation. The nacelle and the turbine can be placed without using a high crane. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.

Laser Consult Ltd. posted this:Vertical axis wind turbine for slow and changing wind speedOne of our partner company active in the fields of construction, trade and services has developed a solution to accelerate and regulate the wind speed to handle low wind speed and high wind gusts. The presented product is in the capacity range where other vertical axis wind turbines (VAWTs) are however its energy production is more effective. The Hungarian firm is looking for industrial partners interested in licence agreement.

It is effectively a multidirectional anemometer which uses multiple Pitot tubes incorporated into a unique spherical design to provide simultaneous real-time data on all elements of wind and uniquely turbulence.
Universidad de Alcalá-OTRI posted this:Soft Computing Techniques applied to the wind forecast on wind farmsThe novelty of these techniques is the enhancement on the performance over the previous ones that have been certified by several scientific publications in international journals. Among these enhancements we must remark the use of several meteorological models with the regression models simultaneously and new training methods for the regression systems.
Universidad de Alcalá-OTRI posted this:Analysis and heuristic optimization software system for wind farm design.The utilization of technologies of soft computing has been vaguely applied to the optimization of the design of wind farms, and only with a limited set of parameters. Gheode group has developed a series of algorithms that consider in a much more realistic way the designing of parks, having in addition a great versatility to incorporate improvements or made-to-measure expansions for every client in particular.
Universidad de Alcalá-OTRI posted this:Using artificial intelligence to shorten the time in the wind turbine design process.Nowadays, aerodynamic industry makes use of exclusively customary techniques over the different stages composing the design process. These techniques require some computing time (depending on the accuracy provided), which bounds the number of different designs that can be taken into account. By reducing that time through the use of new methods in artificial intelligence, it is possible increasing the amount of considered designs.
Brunel University London posted this:DRooTES: Double Rooted Trailing Edge Serrations for quiet bladesAerofoil blade designs with double rooted serrations that reduce trailing edge noise to the maximum through destructive interference. They can be attached to existing blades so are particularly suitable for retrofitting to larger blades, such as wind turbines. They are however applicable to a wide range of blades moving in air and water, for example turbines, fans, rotary wings and fixed wings. The scale of application ranges from small drones (small blades operating at high speeds) to large wind turbines (large blades operating at slower speeds).
Brunel University London posted this:Actively-Controlled Morphing Wing Adaptive Skin for Enhanced Aircraft Control and PerformanceTo meet the ever increasing demand for more efficient, robust, and cost effective aircraft wing designs, conventional control surface methodologies need to be replaced by “morphing” technologies. Brunel University has developed a viable and realistic active wing/blade twist technology with an adaptive skin for seamless and adjustable changes in wing/blade twist angle. The technology is the ability to maintain a rigid skin with a low drag (smooth surface finish) despite high twist deformation during operation. Moreover, the structure is lightweight, and strong enough to carry aerodynamic loads.
Brunel University London posted this:Zagblade: Reduction of aero acoustic pollution by introducing novel serrated trailing edgesAn aerofoil blade design that reduces trailing edge noise by means of a saw-tooth serration filled with a porous material. The serration and porous material work constructively with each other to significantly improve the aero-acoustic performance. An optimal choice of the porous materials has been identified, where it can achieve broadband noise reduction whilst completely suppressing the vortex shedding tone. This new device is more industrially-ready than the conventional “add-on” type serration due to its superior structural integrity. In addition it produces an aerodynamic performance similar to that of the baseline aerofoil. Applicable to a wide range from applications from drones, UAVs, aircraft engines, wind turbines and fan blades.
