At LM Glasfiber in Lunderskov, Helge Sander, the Danish Minister of Science has inaugurated the world’s first wind tunnel custom-designed for research and testing of the aerodynamic properties of rotor blades.

The tunnel represents an investment of DKK 25 million. The wind tunnel will give LM Glasfiber’s team of aerodynamic scientists and engineers a world-exclusive opportunity to conduct tests, 24 hours a day, 365 days a year, to develop the optimum aerodynamic blade design. This design consistently balances on a compromise in which the objective is to extract as much power from the wind as possible while at the same time minimising the load on the wind turbine. The optimum solution cannot be based on theory alone. It must be tested under conditions identical to those in the real world. This is the kind of tests performed in the new wind tunnel, and its design will allow LM Glasfiber to recreate the operating conditions of the rotor blades with a higher degree of precision than previously.
