Jr. nr. 64013-0115
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™The X-Stiffener™ prevents longitudinal cracks on the leading edge of the blades. Longitudinal cracks on the leading edge are very often found after only a few years of operation. The X-Stiffener™ connects the two sides of the blades like a cross in a bookshelf. Experimental and theoretical modelling has proven that the X-Stiffener™ significantly reduces the twisting and hence the peeling stresses are reduced to non-critical levels.

CORTIR - (Cost and Risk Tool for Interim and preventive Repair)
The project aims to cope with the various challenges of the appropriate maintenance strategies. A Cost and Reliability Tool (CAR Tool) will be developed. The vision of this project is to make the decision-making process regarding maintenance decisions easier and to support the entire value chain on how to minimize risk, operation and maintenance cost. |
RATZ - (Root Area and Transition Zone)
The aim of this project is to demonstrate and develop a retrofit solution, the Floor™ (a Bladena patent), for avoiding crack development due to edgewise loading of the blade. The project address a serious problem seen in the field, which pose an extensive operation and maintenance cost for the wind turbine owners. |
