The effect of blade-tower interaction on the structure loading of multi megawatt horizontal axis wind turbine

The aim of this work is to investigate the blade-tower interaction of multi megawatts upwind horizontal axis wind turbine (HAWT). With the increasing of the tower height, tower base becomes bigger and transportation problems appear. Nowadays, the tower dimensions are almost reached roads limits. To optimize tower dimensions there is the need to get a better understanding of what loads act on the tower.
