The Front Cover

In order to keep a wind power plant in operation reliably, regular maintenance work is essential. The rotors, in particular, bear enormous mechanical stress and therefore require regular periodic checking for failures. The image of the cover shows the development of a special self-propelled robot, which enables inspections on the surface of a wind turbine?s rotor blades to be carried out mechanically. On page 6 you will find the article about this development.
