Controlling Erosion Protecting & repairing turbine blades

摘要

IN THE EARLY DAYS OF WIND TURBINES, blades were built like old Cadillacs, with the strength to take hits with minimal damage. In recent years, however, as turbines have grown taller and blades have grown larger and larger, the materials used to build them have become lighter. This is a good thing for overall efficiency of a turbine but, unfortunately, it also means that blades are more vulnerable to damage.
