A consistent focus on research helps maintain our leadership position. LM Wind Power conducts extensive R&D in close collaboration with both customers and leading research institutions. Our objective is to develop new technology that makes wind turbines more efficient and extends the service life of both the turbines and the blades.
LINX – Linking Industry to Neutrons and X-rays – is a university and business social partnership launched so that Danish Industry can derive maximum benefit from the two major new research facilities ESS and MAX IV in Lund, Sweden. The purpose of LINX is to understand the structure of the materials and biotechnological products with which the involved companies are working, right down to atomic level, in three dimensions, and over time. The projects in LINX are defined by industry, typically based on challenges related to materials, components and biotechnological products. With the new technology at hand, companies will be able to achieve a unique understanding that will give them an edge in international competition. So far, a number of leading Danish companies have decided to invest in the project, both financially and by allocating manpower—both producers of concrete, juice, milk cartons, laboratory equipment, and wind turbine blades—to name but a few. Participation in LINX will provide LM Wind Power with a state of the art blade quality inspection system as well as an improved understanding of resin flow into the blade material in order to increase the material quality and reduce the cycle time for blade production. Both results will help LM to maintain the position as the preferred supplier of high quality wind turbine rotor blades for the wind industry.

Wind turbine blades are designed to a 20 year life-time, and during this period the blades are exposed to a number of rotations in the order 1e8 to 1e9. This large number of load-cycles with time degrades the composite material, and the phenomenon is known as fatigue. Fatigue resistance is a thus key parameter for wind turbine blade material design, and the fatigue damage propagation is not yet fully understood. Using in-situ and ex-situ 3D X-ray imaging and analysis technologies, the fatigue damage mechanisms in the composite materials are investigated and described. Thereby, by correlating fatigue performance to local changes in the microstructure it will become possible to optimize the materials, leading to blades with higher efficiency, longer lifetime and lower cost.
CINEMA, or “the allianCe for ImagiNg of Energy MAterials”, is a cross collaborative research platform which will develop unique 3D micro-structural characterization methods in order to make it possible to investigate materials and components under realistic conditions and in real time. The alliance will accelerate the introduction of energy technologies with improved efficiency or lifetime, significantly. Furthermore, the methods developed will be unique tools for quality control of materials and components, thereby reducing cost and supporting standardization.
The alliance joins three strong Danish groups, which have pioneered 3D X-ray imaging and analysis, and internationally renowned research leaders in wind turbine materials, fuel cell development, catalyst design and CO2-solid interactions. Four industry partners will ensure a close focus on the most technologically relevant problems, while international partners will bring access to additional state-of-the-art facilities and modelling competences.

The objective of the project is to demonstrate the technical and economic feasibility of innovative and more reliable solutions for multi MW wind turbines in order to improve the competitiveness of wind energy technologies. The selected components of the wind turbine are the rotor (specifically the blade), power electronics (specifically the converter) and Control and communication system (specifically the controller system).
LM Wind Power is leading a work package on improved rotor blades. The focus of this part of the project is to increase power production, reduce cost of energy and decrease loads on the wind turbines, all of which have a direct impact on the flexibility and reliability of wind turbines. The specific actions focus on 1) Design and manufacture of a reliable blade, 2) Aerodynamic control technologies and 3) Application of materials for erosion protection.The project will demonstrate the reliability of the proposed solution on an onshore 2MW prototype turbine and will also extrapolate conclusion to larger wind turbine and off-shore locations.

The overall objective of the project is to evaluate, validate and improve aerodynamic and aero-elastic tools to ensure applicability for large 10-20 MW wind turbines. In the AVATAR work plan aerodynamic models are developed and calibrated for all aspects which play a role in the design of large wind turbines. The development of new comprehensive models is based on high fidelity tools feed results towards the lower complexity tools where furthermore (wind tunnel and field) measurements are used to validate and improve the models. The capabilities of the resulting tools are demonstrated on a large scale rotor with and without flow control devices.
The project is carried out by an absolute world class consortium with participants from the subprogram aerodynamics of EERA Joint Program Wind in which all leading institutes on the field of aerodynamics participate, complimented with two leading industrial partners.

The aim of the NextRotor project is to develop the design basis for future low noise wind turbine blades without compromising the wind turbine efficiency. The idea behind the collaboration is to develop a reliable integrated rotor design tool and to design efficient, low noise rotors that are demanded in the future wind energy market for onshore application. The project partners expect a possible 2 dB(A) reduction of noise compared to current state-of-the-art rotor design.

We never run out of patents
With over 190 patent families to our credit, LM Wind Power is amongst the pioneers of technological advancement in the wind industry.
We received our first patent way back in 1968 for a special conveyor used to transfer live fish into a lorry. This history of innovation continues today: since beginning to develop wind turbine blades in 1978, we have patented more than 190 inventions.
