Abstract

The present invention discloses a system and method of mounting nacelle(5) over the turbine(T) at inverted position and the generation of power by stacking the airfoil blade(s) (1) on top of each other. The wind turbine along with the rotor(2) is mounted on the tower with bearings for accommodating any axial misalignment. The nacelle(5) at inverted position is mounted over the turbine(T) rather than mounting it beneath the turbine. A support plate (6) holds the nacelle(5) and it transmits the vibration of the nacelle(5) to the ground by means of guy wires(7). The rotor(2) has provisions for stacking the airfoil blade(s) (1) for more generation of power according to the need. Since the guy wires(7) are anchored to the tip of the turbine at the nacelle support plate or truss(6), the wobbling action of the turbine(T) is considerably reduced thereby it enhances rigidity to the structure.
