23 & 24 June, Roskilde (Denmark)

The EERA SP7 Workshop on ”Rotor Blade Materials, Components Structures” (EERA SP7 Blade Workshop) takes place June 23-24 2022 in RoskildeDenmark

Aim of the workshop

Join participants from leading research organizations in Europe to discuss and exchange the latest research in manufacturing, modelling and testing of next-generation wind turbine blades across material, component and structural scales.


The meeting room in the basement of building 101 at the DTU Risoe campus. DTU Risoe campus, Frederiksborgvej 399, 4000 Roskilde, Denmark
