EUDP Logo

The LEX project is a 3-year demonstration project started in July 2013 with a total budget of €4m whereof €2m are supported by the EUDP-programme. The aim of the project is to develop and demonstrate cost effective solutions for mitigating leading edge damages on blades for both existing and future wind turbines.​ ​The LEX project is supported by the Energy Technology Development and Demonstration Program (EUDP), which is administered by the Danish Energy Agency.

X-Stiffener™

Built to prevent leading edge cracks.
X-Stiffener™ counters twisting and peeling stresses, reducing the risk of longitudinal cracking on the leading edge.

How it works

Acts like a cross brace in a bookshelf, stabilising the blade to avoid shear web deformation caused by gravity and aerodynamic forces.

Benefits as a repair

  • Increases blade durability
  • Prevents early-stage cracks
  • Adds strength without adding weight
