The erosion of materials used in wind turbine blades due to the effect of weather conditions is a problem that applies to the whole wind energy sector. VTT's antiAGE project found a functional solution to the material problem with the help of artificial intelligence and 3-D printing.

The erosion of wind turbine blade material is a surprisingly costly problem, which no one had been able to solve before.

Blade - Material - Erodes - Effect - Rain

"The blade material erodes due to the effect of rain, hailstones and sand dust, which significantly reduces the service life of wind turbines. Accelerated replacement of turbines becomes expensive: up to 2 to 4 percent of the value of all wind-generated power is lost as a result of this problem," says Principal Scientist Anssi Laukkanen from VTT.

"It is a question of a classic problem within this particular industry that costs billions of euros and brings additional costs to all wind energy. As wind turbine sizes increase and wind farms are placed out on the sea in increasingly demanding conditions, the significance of the problem becomes emphasised", says Laukkanen.

AntiAGE - Project - VTT - Material - Problem

In its antiAGE project, VTT modelled the material problem and set out to solve it virtually. This is the first time that AI was used for developing a material solution in this scale.

In principle, it is possible to find an unlimited number of different variations for the material used in wind turbine blades composed of the same material components but differing slightly from one another. Of all these alternatives, one would need to find the one that is best suited for this particular purpose and meets its operational requirements.
