Abstract

This repository contains the Leading Edge Roughness (LER) topographies obtained in the LERCat project funded by the Danish Energy Agency (EUDP-64021-2027). The LERCat project was a collaborative effort involving DTU Wind, Vestas Wind Systems A/S, Siemens Gamesa Renewable Energy A/S, LM Wind Power A/S, Suzlon Energy Nederlands Branch, PowerCurve ApS.Each item contains 3D data of unfolded LER topographies obtained from surface scans of wind turbine blades. The topographies can be applied on other aerofoil by wrapping them around the leading edge.The number of unfolded topographies is updated as they become available.
