Abstract

At DTU Wind Energy, a 12.6 m reference wind turbine rotor blade and the corresponding blade moulds were designed and manufactured. The entire blade design and the related test data will be published according to the FAIR principles. The blade moulds are intended to serve as a blade research and demonstration platform, allowing to realise theoretical concepts and testing these in full-scale on a wind turbine blade and thus enabling a comparison to numerical solutions. In this article, the preliminary blade design progress and process, initial load calculations and a 3D scan of the blade molds are presented.

Highlights

In order to design the blade of tomorrow, researchers and engineers continuously break new ground by developing new methods, concepts and approaches to exceed existing limits and overcome current challenges
The article presents the preliminary design of the DTU 12.6 m blade and the blade moulds
A detailed structural analysis of the wind turbine blade is required before the blade manufacturing process can start

Summary

Introduction

In order to design the blade of tomorrow, researchers and engineers continuously break new ground by developing new methods, concepts and approaches to exceed existing limits and overcome current challenges. The existing reference wind turbine concepts are virtual wind turbines without measurement data to compare with. Existing public available concepts usually focus on detailed aerodynamic and aeroelastic studies, where the theoretical performance and structural response of the wind turbine is investigated. The absence of detailed structural definitions leads to individual interpretation of the design and makes benchmarks studies of structural models difficult as seen in ”Results of the benchmark for blade structural models” (3). The reference turbines concepts lack detailed structural definitions and test data from experiments/field measurements to compare and to validate simulation results in order to quantify the prediction accuracy of numerical tools
