Applied hydromechanics, Vol. 12 (84) ¹ 3, (2010) |
The results of researches by definition of influence of periodic change of installatioï blade angle during one turn of wind turbine (Darrieus type) model with straight blades on powering and moment characteristics of wind turbine, and also on magnitude of wind loading on the wind turbine shaft are shown. Researches carried out by modelling experiment of small wind turbine model in a hydrotray. Ability of a wind turbine model with operated blades to selfstart at rather low flow velocity in hydrotray are shown. An opportunity of substantial growth of operating ratios of flow energy and a torque on wind turbine model shaft and essential decrease of hydrodynamic load on wind turbine model shaft in comparison with an analogous model with rigidly fixed blades are shown also. |
KEY WORDS: hydrodynamic load, installatioï blade angle, flow energy |
