Abstract

Abstract: Wind turbine blade is one of the core components of wind turbine, affected by rain, snow, wind and sand, hail and other harsh weather factors, the leading edge of wind turbine blade in long-term operation will produce serious erosion damage, resulting in delamination cracks at the leading edge joints, thus seriously affecting the structural stability of the blade. In order to develop a better coating for blade protection and to maintain the blade better, it is necessary to study the rain erosion test of the blades. This paper systematically introduces the process of wind turbine blades and their coatings affected by rain erosion, rain erosion mechanism, rain erosion test methods, types of test equipment, and rain erosion assessment methods, hoping to provide a reference for the industry to carry out research on rain erosion protection of wind turbine blades.

Key words: wind turbine blades, rain erosion, erosion mechanism, coatings, test, composites
