wind turbine blade, abrasive wear, degradation evolutionAbstract
In the frame of increasing need for renewable energy harvesting, the wind turbines stand as one of the most promising solutions. Taking into account that one of the most exposed parts of a wind turbine is the propeller, since the blades are subjected to an intensive abrasive wearing processes, an analysis of the consequent degradations will be valuable in order to establish the ways to prolong the turbine's working life.
Starting from a structural analysis of an industrial blade and several wear tests performed in abrasive environment conditions, the present paper try to identify the most exposed parts of the blade and the degradation evolution during the wearing process. The obtained results allow the establishing of a maintenance strategy leading to a prolonged working life of the blade.
