    Dynamic Analysis of Innovative Hybrid Wind Mill Tower

    The wind mill towers are constructed using monopoles or lattice type tower. As the height of tower increases it gives more power but it becomes uneconomical, So in this research work innovative hybrid wind mill tower such as combination of monopole and lattice tower is analyzed using FEM software
