Abstract:
Under the circumstances of the total energetic recourses deficit in the Republic of Moldova appears the problem of non-traditional
sources utilization. An important source of renewable energy is the wind energy. This paper deals with two new concepts of
vertical axis wind turbine (VAWT) with helical blades, elaborated by the authors.
The main element of the wind turbine is, certainly, the rotor. It is directly subdued to the action of the air flow and transforms the
kinetic energy of the air-masses into mechanical energy, having as basis the forces of interaction among the active elements of the
rotor and the air flow, which attack it with a certain speed. In authors’ opinion, the constructive solutions of the wind turbines
presented in this work correspond to a great extent to the requirements advanced to the wind turbine. This fact imposes design and
execution of some experimental prototypes, which would validate the expectations.
The industrial models of vertical axis wind turbines with helical blades and with indicated power of 1500W have been designed
and fabricated. At present they are at the testing stage.
