Revolutionary Technology
Our active pitch control solves the fundamental challenges of conventional vertical axis wind turbines.
Maximized Efficiency
Active pitch control optimizes blade angles in real-time, dramatically improving energy capture compared to conventional VAWTs.
Reduced Vibrations
Dynamic load minimization technology reduces wear and extends turbine lifespan through intelligent pitch adjustment.
Self-Starting
Overcomes the traditional VAWT challenge of poor self-starting capabilities through active pitch optimization.
Simpler Design
Straight blade geometry with multiple supports is easier to manufacture than complex curved HAWT blades.
Higher Density
Achieve up to 30W/m² of wind farm area—6 times the standard 5W/m² through superior wake recovery.
Offshore Ready
Generator at sea level and modular design make it ideal for floating offshore wind farm applications.
How Active Pitching Works
FliHy’s active pitch control continuously adjusts each blade’s angle during the rotation to keep the angle of attack close to optimal. Instead of fighting the changing inflow, the turbine actively uses it.
- Higher annual energy yield from the same swept area
- Smoother loads and significantly reduced vibrations
- Reliable self-starting at lower wind speeds
- Lower drag and safer behaviour when parked or stopped
Where conventional fixed-pitch VAWTs see their performance limited by the changing inflow angle around the rotation, our active pitching approach turns that variability into an advantage.
Proven in the Wind Tunnel
Our active pitch concept has been validated on a fully modular VAWT prototype in the University of Twente wind tunnel, providing a robust research platform to characterize the flow field and wake behaviour.
We are now translating these research results into a 50 kW system designed for both decentralized and floating offshore applications.
