We4Ce has designed ten rotor blade sets for Dutch wind turbine developer TouchWind to support testing of its TW6 turbine—a floating, self-tilting wind turbine featuring a one-piece rotor.
The blades were produced in partnership with Dutch mould manufacturer Kleizen, which developed both the blade moulds and final components. The manufacturing process used a two-component epoxy resin system optimised for Resin Infusion Moulding (RIM), combined with glass fibre reinforcements.
This marks the next prototype phase for TouchWind’s tilting rotor turbine, which features a six-metre-diameter rotor and a capacity of 12 kW. Onshore and offshore testing will assess the turbine’s performance in close array layouts, aimed at validating the high energy density observed in previous wind tunnel studies. The turbine is engineered to endure wind speeds up to 250 km/h.
The design uses aerodynamic lift to “self-tilt” with the wind, maintaining stability and regulating power output. This configuration enables more efficient energy capture from strong winds while reducing structural stress.
Currently being assembled in Eindhoven, the TW6 is set for testing in summer 2025. TouchWind has also started developing a 3–5 MW version of the turbine, targeting future offshore deployment. The company is supported by its main shareholder, Japan-based Mitsui O.S.K. Lines (MOL).
