Every rotor can be improved and very rarely is a turbine operating at its design limit. Anakata's range of aerodynamic add-ons can be tailored to any turbine model to maximise energy capture and reduce noise.
A full set of Anakata winglets can be installed on a turbine in less than one day, and can deliver AEP gains of up to 4%. Anakata's patent pending technology is a very low mass device which delivers a significant increase in torque, and can be used in conjunction with a simple rotor extension to deliver even more power.
Anakata Vortex Generators
Anakata vortex generators can deliver AEP gains of up to 5%. These devices provide a variety of aerodynamic improvements including stall prevention caused by leading edge erosion, and stall prevention at the rotor blade root.
The Anakata lip can deliver AEP gains of up to 2.5% by increasing torque at the rotor blade root. This area of the blade is often neglected and as a result almost all turbines can benefit from this device.
Anakata serrations can reduce sound emissions by around 2dB. This is important at noise sensitive sites where power production has been de-rated in order to comply with requirements for low sound levels. This device enables power production to be up-rated without exceeding sound level limits. AEP gains can be significant.
Different combinations of Anakata devices can deliver AEP gains of up to 10% with a typical payback period of less than 2 years.
Anakata will undertake a free evaluation of your wind turbine to determine its potential for aerodynamic upgrade.
Every rotor can be improved and very rarely is a turbine operating at its design limit. Anakata’s range of aerodynamic add-ons will be tailored to your turbine model to maximise energy capture and reduce noise.
Our wide selection of devices means that you can customise site installation on a turbine-by-turbine basis. Our next-generation of add-on devices are inspired by cutting-edge Formula One technology and include Vortex Generators, Winglets, Lips and Serrations. Anakata uses the latest design and manufacturing techniques and has it’s add-on technology installed on OnShore and OffShore MW-class turbines. These add-ons are available for both Retro-Fit and OEM Factory-Fit customers. AEP gains of up to 10% can be achieved with a short payback period of typically less than 2 years. Anakata will undertake a free evaluation of your wind turbine to determine its potential for aerodynamic upgrade. This allows us to understand the performance of the blade from root to tip, and recommend the optimum combination of add-on kit to maximise AEP. Central to this process are customer requirements for ROI (Return on Investment).
Power performance analysis of the upgraded turbine is carried out using the industry-standard methods of comparing 3-6 months of SCADA data to a control turbine. Please contact email@example.com to arrange an appraisal.
Is your rotor working hard enough for you?
The rotor is the first phase of the energy transformation process from kinetic wind energy into mechanical torque, and as such is where investment in technology should be maximised. Aerodynamics is overlooked by many wind turbine designers because they do not understand what is possible; as such they continue to use out-dated technology and design methods.
Compared to blades using standard aerofoils (e.g. NACA/FFA/DU), Anakata blades produce up to 3% more AEP and are up to 3dB quieter, or 25% lighter.
Anakata designs holistically using a combination of industry-standard BEM modelling, advanced full-rotor 3D CFD methods, and wind tunnel testing. We have experience of testing in a number of state-of-the-art wind tunnels including Deutsche WindGuard, Cologne KKK, Stuttgart LWK, Virginia Tech., Mercedes F1, and Williams F1. We use a variety of testing techniques including full 3D model motion systems and infrared boundary layer visualisations.
Our wealth of design experience allows us to optimise blades to your requirements to achieve the best compromise of AEP, loads, and cost.
Trying to break the technology curve with your next rotor?
Anakata is your partner of choice for advanced blade technology development. Whether it is evaluating and progressing your own designs or licensing our unique Formula One-inspired technology, we can help you stay ahead of the competition.
We are specialists in novel aero-structural concepts, aero-elasticity for load control, fluidic logic, and cutting-edge composite design.
There is more money spent globally on aerodynamics R&D in Formula One than in the aerospace and wind turbine industries combined, yet technology transfer is scarce between these industries. Anakata UK is creating a fusion between these fields.
After technical inspection by the UK Government as well as industrial and academic experts, Anakata has been awarded a grant by the UK Department for Energy and Climate Change to develop a 15m-diameter advanced technology demonstrator wind turbine rotor. The blades for this prototype will be installed in the UK to showcase some of our design philosophies and blue-sky development.
Anakata has formed a technology partnership with the Dutch wind turbine manufacturer EWT – the world’s leading turbine supplier for localised energy generation and repowering - to collaborate on the development of next-generation blade technology.
Anakata has been selected as a finalist of the 2019 Shell Springboard low-carbon innovation awards. In April Anakata presented its advanced aerodynamic upgrade technology for wind turbines at one of two Shell Springboard regional finals. Anakata was one of six finalists to be awarded funding and the opportunity to compete at the national final in July.
