CORUS Centre joins forces with LM Glasfiber, world giant in wind turbine blade manufacturing, to conduct a research project

GASPE, QUEBEC--(Marketwire - Oct. 30, 2007) - The CORUS Centre, LM Glasfiber Canada and the Ion Beam Laboratory (LAFI), a branch of the National Scientific Research Institute (INRS), have joined forces to develop a surface treatment process to reduce the formation and accumulation of ice on the external structures of wind turbines. The use of this new technique would ultimately reduce the impact of ice accretion on the operation and performance of wind turbines.

The project aims to develop an anti-icing surface treatment for wind turbine blades based on ion implantation and UV ray irradiation, and to optimise the technique's parameters to scale up the process to the industrial level. Throughout the project, ice adherence will be measured before and after each type of treatment to assess the effectiveness of the process.

"The accretion and growth of ice on blades are responsible not only for the loss of the blade's aerodynamic profile but also for problems due to increased vibrations, mechanical constraints and fatigue. Depending on the frequency and severity of icing events, these phenomena can lead to considerable production losses," says Dr. Redouane Megateli, Scientific Director of the CORUS Centre.

LM Glasfiber, the world's largest blade manufacturer, will financially support the project and provide blade material samples and external coatings for the tests. The surface treatment technique will not affect the blade manufacturing process used by LM Glasfiber. It will be applied subsequently, as an additional finishing operation, to modify the surface chemical properties at the nano-scale.

Jesper Mansson, Research Director LM Glasfiber said: "Adapting wind turbines to cold climate conditions such as the severe North American weather represents a considerable potential. The development of an anti-frost treatment process will in particular help extend the lifetime of installations and wind turbines and indeed help overcome the impact of frost on the operation of these installations and wind turbines."

The National Scientific Research Institute (INRS) is the academic partner in this innovative project. LAFI, working in collaboration with LM Glasfiber Canada and the CORUS Centre, will lead and manage the project. The laboratory will be responsible for setting up the ion implantation and UV ray irradiation process parameters and for characterising and assessing the effectiveness of the project processes. The CORUS Centre will be in charge of the coordination of the project at the scientific level and the technology transfer aspect jointly with LM Glasfiber Canada. The ultimate goal is to implement the research findings in the industry.

An application for project funding has been sent to the Natural Sciences and Engineering Research Council of Canada (NSERQ) for an amount of $50,000. The first phases of this project will be carried out over the next 18 months.

The CORUS Centre is a research, development and technology transfer centre
that studies the impact of nordic conditions on wind energy production. It
research facilities are located in Murdochville, Quebec, in a unique
natural laboratory at an elevation of 660 metres where wind speeds average
9 m/s. The CORUS Centre is the scientific branch of the Wind Energy
TechnoCentre, and is a recognised college-level technology transfer centre
