Blade Dynamics 78 metre offshore wind turbine rotor blade arrives for testing at ORE Catapult’s National Renewable Energy Centre.

World first ‘modular design’ blade set to increase output, reduce weight and lower costs

One of the most innovative offshore wind turbine rotor blades in the world has arrived today at the Offshore Renewable Energy Catapult’s test, demonstration and research centre in Blyth, Northumberland, ahead of a planned six month testing programme.

UK based Blade Dynamics’ prototype ‘D78’ blade has been designed and manufactured in both the UK and USA and made its way, from the NASA Michoud Assembly Facility in New Orleans, to the UK for commissioning and testing. Its modular assembly design is unique, enabling larger, more effective turbines with reduced weight and higher performance. The final stages of the manufacturing process can be completed close to the installation or deployment site, allowing manufacturing to be distributed around the country and providing a route for the future export of blade components from the UK.

The only offshore assembly blade in the world will undertake approximately six months of testing at the Catapult’s world leading facilities in Blyth.

The only offshore assembly blade in the world

Pepe Carnevale, CEO of Blade Dynamics, said

"ORE Catapult’s National Renewable Energy Centre has world-class facilities and is Blade Dynamics' partner of choice for full-scale blade structural testing.

This high performance 78m modular assembly blade will undergo static and dynamic testing here in the coming months. Independent verification that the technology is reliable is an important step in the progression towards serial installation.

We are also actively exploring demonstration opportunities for our 78m blades. Making these steps, with assistance from ORE Catapult, is key for Blade Dynamics. It will drive the introduction of this technology to the market and support all the sustainable job creation, export-led economic growth and reduction in the cost of offshore wind energy that the technology can deliver.

This incredible 78m blade has only been possible with the tremendous support of the ETI, who's commitment and vision is accelerating this game changing innovation into UK offshore wind and the UK economy. The company would also like to take this opportunity to thank everyone else within the UK wind sector including DECC, TSB, The Carbon Trust, the Catapult network and others who continue to make the UK a great environment for innovation in offshore wind."


Tony Quinn, ORE Catapult’s Operations Director, added:

"This is the longest blade, and certainly the most innovative in terms of design, that we have ever tested at our facility in Blyth. Our range of test methods help to reduce risk in new blade designs and generate confidence in their performance.

Here at the Catapult, we work collaboratively with innovators such as Blade Dynamics to help develop their ideas into market ready technologies, and tackle some of the industry’s major technology challenges to drive down the cost of offshore renewable energy."

August 2015

Blade Dynamics has announced the launch of the first D78 blade from its NASA-based manufacturing facility in New Orleans. The blade was supported by the UK’s Energy Technologies Institute (ETI).

Blade Dynamics is shipping the “D78” advanced assembly blade to the UK from its NASA-based facility to be structurally tested at the Offshore Renewable Energy (ORE) Catapult’s blade testing facility at Blyth, UK.
This is the only modular offshore blade in the world. There are multiple new technologies in the blade including a lightweight and high dimensional accuracy blade tip with built-in leading edge protection. The blade technology has been designed and engineered for simplicity of manufacture in order to reduce variation and ensure better control of quality. The modular technology also has significant benefits in the supply chain, simplifies blade transportation, and allows wind turbines to be designed and built to produce an overall lower cost of energy.

The Energy Technology Institute in the UK has supported the development since 2012.

Dr David Clarke, CEO ETI said

"ETI supported this technology development because blades have been a limiting factor for the cost and performance of offshore wind, and this was an opportunity to demonstrate what is possible. The 78m blade uses technology capable of making rotors whose diameters can reach beyond 200m, enabling larger, more effective turbines and leading to a reduced cost of energy. Once commercialised, this technology can create a pathway to improving performance, reliability and cost for offshore wind as well as providing an exciting route for the future export of blade components from the UK. We look forward to the structural testing at ORE Catapult in the UK and are investigating ways to demonstrate a rotor using this technology on the 7MW turbine that ORE Catapult is in the process of acquiring."

Pepe Carnevale, CEO Blade Dynamics said

"All the technology behind this blade has been developed in-house by Blade Dynamics and I am very proud to be part of such a great team. Along the way there has been support from DECC, Carbon Trust, The Dow Chemical Company, NASA and most importantly the ETI. The D78 blade was designed based on cooperation with Siemens turbine, but the aeroshape and structural design are 100% Blade Dynamics. We have received quite some interest from different OEMs to fly the D78 after the ORE Catapult test and obtain a longer rotor making their turbines more competitive." "The UK has a great tradition of innovation in many industries that intersect and are highly relevant to large, high performance wind turbine blades and this new blade type is a great opportunity for the UK. First and foremost, this can reduce the cost of energy very significantly, but there are also several other unique benefits. Because the blades are assembled from smaller components, we are not constrained by expensive new factories dependent for survival on a very limited local market, making big blades in one big factory. The technology allows the existing British composites industry - boat builders, aircraft parts manufacturers, automotive suppliers and others - to supply transportable components from the UK. The most interesting aspect is that because these smaller components are easily shippable and assembly can be done in a simple warehouse building, blades can be assembled anywhere, with limited setup cost, in the UK or abroad. This creates an export market for blades and allows established UK companies to participate in the wind turbine blade supply chain, which is otherwise very difficult to see happening. This blade, and this technology, is a real game changer."

Simon Edmonds, Director, Catapult Programme at Innovate UK, said

"This is the largest blade the Offshore Renewable Energy Catapult has ever tested and we welcome Blade Dynamics to the world class facility in Blyth. The company is also working with Offshore Renewable Energy Catapult on leading edge erosion technology, as well as with the National Composites Centre, The High Value Manufacturing Catapult, and exploring turbine test demonstration options with Catapult. This really is a British energy industry success story, using all of the support from government designed to nurture new technology and develop innovative energy solutions for the UK economy."

Blade Dynamics D78m in factory

The D78 Blade was partly constructed at Blade Dynamics’ facilities in the UK and the US. In the US, Blade Dynamics operates from the NASA Michoud Assembly Facility, which has 43 acres under one roof. The same building built revolutionary boats and planes in the Second World War, constructed the main booster for the Saturn 5 rocket program and the external fuel tank for the Space Shuttle program. It is currently developing fuel tanks for the Space Launch System, and Blade Dynamics share the facility with Boeing and Lockheed Martin.

The overall blade design and the manufacture of the separate blade tip were completed in the UK. The main blade section was assembled and then joined to the tip in the US, before being shipped to the UK for testing.

The completed blade was moved from the NASA assembly facility to the on-site port using transportation equipment designed and last used for the Space Shuttle program.This included the heavy-duty towing equipment last used for towing the Space Shuttle’s main fuel tanks.

Blade Dynamics have announced today the award of Process Technology Innovation Funding under the GROW:OffshoreWind program for a £1m Advanced Blade Tip development project.

Blade Dynamics have announced today the award of Process Technology Innovation Funding under the GROW:OffshoreWind program for a £1m Advanced Blade Tip development project.

Blade Dynamics announces today the award of Process Technology Innovation Funding under the GROW:OffshoreWind program for a £1m Advanced Blade Tip development project, due for completion in Q2 2015.

The performance of offshore wind turbine blades in their challenging operating environment is one of the critical issues in energy cost, reliability and safety. Costs associated with repairing blades are extremely high and time consuming, causing significant operating losses due to downtime and having a significant detrimental effect on the cost of energy generated.

Blade Dynamics have created a new and highly innovative ‘Advanced Blade Tip’, which improves the critical outer third of a wind turbine blade. This high performance tip is designed to integrate into standard wind turbine blades, creating a ‘hybrid blade’ that upgrades performance whilst using existing manufacturing infrastructure. It features built-in leading edge erosion protection, has a highly accurate aerodynamic profile to enhance energy generation, is lightweight to reduce turbine loads and to allow blades to be extended in length and has an innovative lightning protection system. The Advanced Blade Tip both enhances the performance of offshore wind turbines, increasing Annual Energy Production (AEP), and reduces costs incurred through expensive downtime due to blade deterioration and the current need for frequent maintenance.

The project will refine, demonstrate and test the manufacturing technologies used in the tip solution as well as optimise the design of the interface between the tip and the rest of the blade.

Theo Botha, Blade Dynamics co-founder said:

"This is an exciting new technology development that can substantially reduce the long term cost of energy from offshore wind turbines and the company is proud and thankful to be supported by GROW:OffshoreWind in this work.

The project is a great example of funding being provided for technologies that can have a substantial positive impact on the British economy and environment by nurturing sustainable, knowledge based, domestic manufacturing in the vitally important offshore wind energy sector.

The outer portion of a blade produces most of the energy and the technology allows these high value blade tips to be exported from the UK and deployed on offshore wind turbines globally as well as in the domestic market."

Dominic Brown, CEO GROW:OffshoreWind said

"We are delighted to support Blade Dynamics in making these important technology innovations for offshore wind turbine blades.

The successful delivery of this project will provide a route for substantial financial benefits to both the purchasers of wind turbines and manufacturers, through increased blade life and significantly reduced maintenance costs, as well as a reduction in the cost of energy from offshore wind farms.

This is a significant project and one of a number now supported by GROW to assist with supply chain development and address the cost challenges faced by the industry. We look forward to it’s successful completion and to many more like it in the future."

Blade Dynamics and SABIC announce technology licensing agreement for advanced blade manufacture in GCC and Egypt

Blade Dynamics and SABIC announce technology licensing agreement for advanced blade manufacture

Blade Dynamics and SABIC have announced a technology license agreement today; for the manufacture of high performance wind turbine blades and their deployment in the GCC (Gulf Cooperation Council) and Egypt.

Blade Dynamics introduced a breakthrough design and manufacturing process, which constructs blades through the assembly of smaller, more accurate and easily manufactured component pieces, rather than from extremely large and expensive full-length mouldings.

This results in advantages including better weight/length ratio, better reproducibility, easier logistics. The Dynamic 49 Blade was recently awarded blade of the year 2012 by Windpower Monthly Magazine. This development is progressing with the recently announced Energy Technologies Institute Long Blade Programme. This project is expected to create the longest and most advanced wind turbine rotor ever built.

Ernesto Occhiello, EVP Technology and Innovation of SABIC said: "SABIC's approach is to selectively identify and make available to KSA breakthrough technologies. Blade Dynamics's blades are particularly suited, given the importance of high energy yield in lower wind conditions and adequate resistance to sand erosion".

Pepe Carnevale, Blade Dynamics' CEO said: "Following the recent announcement of the company's development programme for the largest blades ever manufactured, this licensing agreement is another step toward commercialisation of this next-generation blade technology."

THE BEST OF THE BEST BLADES 2012
Click here for details of the shortlist
WINNER - Blade Dynamics D-49 prototype blade

Blade Dynamics manufactures its turbine blades in relatively short, easy-to-handle individual components, fitting into standard 40-foot containers. Not only are these far simpler to transport than single-piece blades of similar size, these smaller parts are claimed to be easier to manufacture at very high quality. Assembly takes place in laser-aligned jigs that are easy to install and dismantle.

Core to the design of this small UK manufacturer is an inner-spar technology built from many multi-layer, carbon-fibre-reinforced epoxy sections. Precision moulds can produce repeatable, high-quality, single-spars, which fit into stiff box-type structures, carrying the main loads.

The outer shell elements are built predominantly in glass-fibre-reinforced composite, providing aerodynamic cladding and also contributing to the blade's structural integrity.

Thin walls

The blade root design is another key feature, reducing the weight of typical blade roots. It comprises opposing thin-wall inner and outer sections shaped like corrugated iron. Laminated together, they create multiple tapering, round holes in the root circumference to take inner steel thread elements for the company's patented blade bolts with inner steel thread elements. These three parts create a very strong and stiff structure, while remaining lightweight.

The blade root wall thickness of the D49 with bolt inserts is 20-25 millimetres, compared with a conventional blade root of between 80 and 100 millimetres.

ETI invests £15.5 million in new turbine blade design with Blade Dynamics to enable the building of the world's largest wind turbine blades

ETI invests £15.5 million in new turbine blade design with Blade Dynamics

The Energy Technologies Institute (ETI) has appointed Blade Dynamics to develop and demonstrate the technologies for constructing what are expected to be the world's longest wind turbine blades ever built.

As part of the £15.5 million project the ETI will become an equity investor in the Isle of Wight-based blade developer - helping with technology development and allowing the company to grow its workforce by up to a third in the short to medium term.

This is the second time in 12 months that the ETI has undertaken a private equity investment in a UK SME developing innovative new technologies.

Blade Dynamics will construct blades for the ETI of between 80 to 100 metres in length, incorporating carbon fibre rather than conventional fibre glass. This compares with blades now deployed offshore of between 60 to 75 metres in length.

The ETI commissioned and funded project will be delivered using BladeDynamics' innovative design and manufacturing processes that construct blades through the assembly of smaller, more accurate and easily manufactured component pieces, rather than from extremely large and expensive full-length mouldings.

The project will see prototype blades manufactured, and in a position to be put into production by late 2014. Structural testing for the first blade is then expected to be carried out at a UK test facility. The design of the blades will see them weigh up to 40 per cent less than conventional glass-fibre blades, enabling significant weight and cost savings to be achieved throughout the rest of the turbine system. The design will also help to reduce the cost of the energy produced.

The intended end use for the blade technology is on the next generation of large offshore wind turbines currently under development with a capacity of 8 to 10MW. This compares with the 5-6MW capacity turbines currently deployed offshore.

The first stage of the project will focus on blade design in collaboration with a major turbine manufacturer (OEM). The project will also test detailed design and manufacturing technologies, extending Blade Dynamics' current experience from manufacturing 49 metre blades. The second stage will establish and demonstrate the proposed manufacturing processes on blades designed for a current 6MW turbine. A design will also be developed for blades for future 8 to 10MW turbines. Final project stages are intended to test and verify the prototype blade performance against the predicted performance.

Minister for Universities and Science David Willetts, Department for Business, Innovation and Skills, said: "This investment will enable Blade Dynamics to develop and demonstrate a potentially world-leading technology. The project could vastly improve the manufacturing process of very large turbine blades, as well as helping to reduce the cost of the energy generated. It shows Britain is leading the way in developing innovative solutions to help with the transition to a low carbon economy."

Paul Trinick, Offshore Wind Project Manager at the ETI said: "Offshore wind has the potential to be a much larger contributor to the UK energy system if today's costs can be significantly reduced. Investing in this project to develop larger, more efficient blades is a key step for the whole industry in paving the way for more efficient turbines, which will in turn help bring the costs of generating electricity down.

"Along with improved system reliability, the impact of larger blades is a crucial factor in helping to bring down the costs of generating electricity offshore. Our investment strategy here is to provide financial support to allow the company to develop its technology further, to accelerate and expand the testing of this UK technology, and to identify the large-scale development opportunity of this design approach."

David Cripps, Senior Technical Manager, from Blade Dynamics added: "We have worked hard on the design of this blade technology for a number of years now. Financial backing from the ETI for this project allows deployment on ultra-large turbines far sooner than would otherwise have been possible and as a result of this project we will be hiring new engineers and technologists to make this possible. Our driver is to make the generation of electricity through offshore wind both more reliable and more economical. We believe longer, low weight blades to be a key part of the solution, but for such blades to be most effective we need to design their construction differently."

World's most advanced and transportable wind turbine blade successfully tested and GL certified. Boston, MA

World's most advanced and transportable wind turbine blade successfully tested and GL certified.

Blade Dynamics today announces the GL certification of the new "Dynamic 49" wind turbine blade. The Dynamic 49 blade sets new standards for wind power generation. Weighing only 6150kg, the D49 is the lightest blade of this scale in the world and leads others in manufacturing accuracy, lightness, quality and durability. Uniquely, the D49 and all Blade Dynamics rotors can be transported in two separate sections and finished locally, saving great logistics cost. The D49 effectively turbo charges 2MW machines with a larger rotor, boosting AEP and improving the profitability of the wind farm. On an AMSC designed 2MW turbine, the D49 increases AEP by up to 12%, depending on the wind resource.

An advanced 49m wind turbine blade designed by Blade Dynamics, has successfully completed full structural testing for GL certification at the NREL (National Renewable Energy Laboratory) test facility in Boston, USA. The D49 blade was developed by Blade Dynamics with blade fabrication completed at its new US facility at NASA Michoud, New Orleans, USA. Following testing, the blade has passed full GL certification.


The D49 blade uses several proprietary technologies developed by the company to achieve its exceptionally low weight of 6150kg. These technologies include an ultra high-performance carbon fibre spar and a patented root attachment system that dramatically increases strength and reduces both weight and cost. The modular construction enables the blade to be transported in two shorter sections that can be seamlessly consolidated locally using proprietary technology. The blade also uses a slim aerodynamic profile that gives a higher energy yield for equal turbine loads and this is made possible by the advanced composite engineering of the blade.


The blade is well suited to many turbines in the 1.5-2MW range and can transform power curves with it's high yield, low loading characteristics. When the D49 blades replace conventional glass epoxy blades on an AMSC 2MW turbine, AEP (Annual Energy Production) increases up to 12%.


The D49 blade is also ground-breaking in that it is assembled from smaller modular composite mouldings, typically of 12m maximum length. This approach means that each piece can be manufactured to a much higher quality and accuracy, whilst using lower cost tooling than that used in conventional blade manufacture. The modular manufacturing approach can also be used to dramatically reduce blade transportation costs, with the possibility to ship blades in two sections that are joined together local to the wind farm. The assembly approach also enables a flexible, and easily developed, global supply chain.


The technology in the D49 blade is ready to be scaled up to blades for 10MW turbines, and there are already designs for blades almost twice as long as the D49. These blades will be far lighter than existing ultra-large blades, and can make a large improvement in the delivered cost of wind energy, especially in the fast growing offshore sector.


The D49 blade was developed with the assistance of the UK's DECC (Department of Energy and Climate Change), with initial testing carried out at NAREC.


The company has begun serial manufacture of the D49.
