Reshaping
Blade Design
Wind Energy’s
Adaptive Future.
Bringing a fresh perspective, Brayfoil's morphing wing technology draws inspiration from our most precious resource — the natural world.
With a biomimetic design that emulates the wings of African birds of prey, our adaptive turbine blade has huge potential for enhancing wind energy performance.
APPLICATION
Solving the Foundational Problem in Wind Energy
Weight and cost are the barrier to cheap, scalable renewable energy.
Longer turbine blades allow for greater energy production, however blade weight and cost must also be increased to manage loading forces — a large amount of which come from the movement of air across the blade as it moves.
Our patented Morphing Wing Technology allows us to dynamically change the shape of a blade during operation to modulate these loadings, allowing for longer blades and produce more energy.
Longer Blades.
More Power.
Lower Energy Costs.
Brayfoil blades can reduce storm loads by 90%, operational loads by 20% and perturbation sensitivity by 60%.
This means lower design case loadings, allowing for longer blades on the same structure — approximately a 10-15% increase in blade length.
Longer blades allow for more power — and more energy production.
The managed loadings and increased blade length enabled by Brayfoil blade design allows for 20% greater energy output.
Reducing the need to increase weight and cost when utilising longer blades means the increased energy output has a greater financial potential.
In a CAPEX and OPEX-neutral basis, this means wind energy gets cheaper for the consumer and more can be deployed.
Brayfoil technology is inspired by nature.
We observed the ways in which the wings of African birds of prey operated, and soon realised that they offered an elegant, adaptive solution to the problem of excess loading.
Like a bird's wing, Brayfoil biomimetic blades align to the wind conditions. They have a unique shape that causes the wing pitch to change automatically in response to wind angle changes.
With Brayfoil technology, the turbine blade manufacturing process remains largely unchanged. Active components are kept simple — housed safely within the blades, protected from the elements.
This continuity of manufacturing — and the ability to use longer blades without requiring heavy, expensive materials — keeps costs down while significantly increasing the potential of each blade.
We have continually refined our biomimetic concept through rigorous testing — ensuring our adaptive blade is compatible with virtually any turbine model.
Wind power is set to be an even more prevalent source of renewable energy in the years to come, and is projected to have the second-highest emissions impact between now and 2050 — approximately 160 Gt of CO2 across on/offshore wind sectors.
If Brayfoil technology is scaled throughout the wind energy industry between 2027 and 2050, it has the potential to mitigate an additional 30 Gt of CO2.
Our Projected Emissions Impact
We understand that we aren’t creating a market from scratch here — our ambition is to work with the energy sector to add significant performance to an already growing, established market.
So much good work has been done across the wind energy sector, for many decades, and our drive to contribute is inspired by those who have innovated before us.
The exciting part — if we scale through the market between 2027 and 2050, we estimate that we can enable an additional 30 Gt reduction in aggregate global emissions.
For context, this is a figure that exceeds the combined projected impact of electric car usage and clean ocean shipping across the same 23 year period.

Rigorous by Nature
The imagination and innovation involved in developing Brayfoil's adaptive blade technology is driven by the rigor and expertise of our specialist team.
Our collective experience spans an array of engineering disciplines, as well as business, manufacturing and design — and the potential application and operation of our adaptive blade concept is supported by AI and machine learning.
Combining new ideas and established aerodynamics — as our concept develops, so does Brayfoil.
