Abstracts:
In the paper the performance and force characteristics investigation of the wind turbine model are presented. The model was specially designed for laser-optic measurements in the vortex wake of the model. The torque and thrust measurements for tip speed ratios λ =3-8 were made by tenzo sensors, which were mounted in the model of rotor. The measuring system was calibrated. Due to calibration dependences the thrust and torque dependences were obtained in units [N*m] and [N] respectively. Power and thrust coefficient dependences were obtained. In the experiments it was found out that the optimum regime of the designed three-bladed rotor model corresponds to tip speed ratio λ = 5, and the optimum angle of attack lies in the interval α = 0-3 0. Besides, the calculated angle of attack α =0° gave a smaller torque value in comparison with the set angle of attack α =+3°. |
