WindSense: Increasing the Cost Efficiency of Offshore Wind Energy by integrating
Publieke samenvatting / Public summary
Aanleiding
Modern blade designs tend to have a more slender design and as such a smaller blade root, for two reasons. A more slender blade allows to increase the blade length and thus increasing the swept area of the turbine, and with this increase the performance. The length of the blade is quadratic to the energy produced. The second reason to go for a more slender blade is related to road transport, up to a maximum width of 3.5m only a special transport permit is required, for anything wider for each transport, in each municipality a special permit is required. Either the blades cannot be transported to the site or it becomes far more costly.
Doelstelling
To demonstrate in a relevant environment that a root bushings connected rotor blade with optical sensory fibres running from the blade root to the point with the highest chord, will improve the predictability and reliability of material behaviour in such a way, that it is safe to reduce the common over-dimensioning of rotor blades.
