Abstract: The paper deals with determining the effect of periodic variation of blade pitch of vertical axis wind turbine (VAWT) model with straight blades on its power and momentum characteristics. The model experiment has been carried out in a hydrotray for small VAWT models. Performance of VAWT models with rigidly fixed blades to crosspieces of wind turbine model and with two various control mechanism of blades on trajectory of their circular movement are determined. The ability of VAWT with controlled blades to self-starting at quite slow incident flows is shown. The possibility of a double increase of power coefficient and torque coefficient are shown. | ||||
