RESUMO

The paper deals with determining the effect of periodic variation of blade installation angle during one turn of vertical axis wind turbine (VAWT) model on its power and momentum characteristics. Moreover, magnitude of the accompanying wind loading on the VAWT shaft is studied. The model experiment has been carried out in a hydrotray for small VAWT models. It is found that the VAWT with controlled blades is able to self-starting at quite slow incident flows. The essential increase of the torque-to-flow energy ratio is shown, along with the decrease of shaft hydrodynamic load, in comparison with VAWT model with the fixed blades.
