We4Ce, a Dutch rotor blade specialist, has designed and delivered ten rotor blade sets for our upcoming TW6 floating turbine tests. The blades were developed in close cooperation with our engineering team and produced with the expertise of mold specialist Kleizen.
The TW6 — a 6 m rotor, ~12 kW prototype — uses our unique one-piece tilting rotor principle. Unlike conventional three-blade turbines, this design reduces mechanical complexity and withstands extreme winds, ensuring stability and power production even in storms, significantly improving operational continuity.
Design & manufacturing highlights
- Structural and aerodynamic design: We4Ce optimized the blade structure and aerodynamic shell specifically for the tilting rotor concept, eliminating bonding lines in the nose to reduce erosion risk and extend blade life.
- Production method: The blades are produced using vacuum infusion with epoxy resin and glass-fiber reinforcement—ensuring high dimensional accuracy and durability. Production was supported by Kleizen for mold expertise and quality control.
- Quantity & purpose: Ten blade sets will support the assembly and test programme for multiple TW6 prototypes, enabling evaluation of aerodynamic performance and energy yield in realistic conditions.
Testing plan
The TW6 prototypes are being assembled in Eindhoven and are scheduled for both onshore and offshore tests starting in 2026. Test activities will include co-located turbine experiments to validate power density and wake interactions — building on prior wind-tunnel results and small-scale validations.
What this means for TouchWind
These blades are a concrete step forward in our roadmap. The TW6 campaign will give us the data we need to refine larger machines and prepare for demonstrators and, ultimately, commercial turbines.
We thank We4Ce and Kleizen for their collaboration on the TW6 blade sets.
