摘要

Wind turbine installations at near-shore and off-shore sites focuses attention on the operating conditions in very aggressive environments, characterized by the presence of sand, dust and saline moisture in the air stream. The environment causes rotor blade erosion of the leading edge, thinning of the trailing edge and roughness increase all over the rotor blade surface; these effects produce severe performance decay, as lift reduces and drag increases. Test analysis has been performed, with a water-table test-bench at "La Sapienza" University of Rome, on the performances of some new profiles, designed for wind turbine rotor blade applications. The results are compared with literature and previous experimental measures.
