RELIABLADE: Increased Reliability of Rotorblades

Researchers from DTU and Fraunhofer IWES will - together with further partners - develop a design for a 40 meter blade with intentionally inserted errors, manufacture it and test it, in order to improve the understanding of a blade´s structural behavior and validate damage models. The vision is a digital twin of every blade manufactured that would allow a permanent condition monitoring for the entire life cycle.



New project:


The project aims at unleash the full potential of offshore wind energy to be in direct competition with conventional energy sources worldwide. Over the course of the project, a technology platform for the first prototype of a double-digit rated capacity turbine will be developed, installed, operated and tested a realistic environment.
