| Research Abstract |
The mainstream concept of floating offshore wind turbine is the horizontal axis wind turbine (HAWT) mounted on a float system. However, the top-heavy structure is not reasonable in offshore floating condition. The cost of large float system and the safety issue of the maintenance work in the nacelle moving on the top of tower deteriorate the economic performance of the wind turbine.
One solution is the new type floating vertical axis wind turbine, named Floating Axis Wind Turbine (FAWT). In the concept, a cylindrical float is the turbine shaft of rotor. The turbine axis is not in the fixed upright position so that the support structures are significantly reduced. In this research, we investigated the mechanism of rotor support system, experimental method of the wind tunnel test of tilted vertical axis wind turbine, and the influence of gyroscopic effect on the dynamics of floating turbine.
