| The outcomes of researches on definition of influence of a periodic angular variation of the installation of a blade are reduced during one turnover of vertical axis wind turbines (such as Darye rotor) on power and moment performance of wind turbines, and also on its ability in self-start-up. The researches were conducted by modelling experiment in a hydrotray at flow velocities of water 0,3 - 0,7 m/s. The gear of a positional control of blades during rotation of model of a curl allowed to change angles of the installation of a blade from -14° up to +25°. The ability of a rotor with vacillating blades to self-start is shown at very low rates of a ram airflow. Significant increase of the working moment is shown the shaft in comparison with a wind turbines with hard-mounted blades. |
