Aerodynamic bases and effects of new wind turbines
Description
Wind is a clean and renewable energy sources, however having one failure: low profitability in zones of weaker potential. However, by using a new type of wind turbine built in regulable mantle's nozzle, which replaces the free air stream of wind into into programmed i.e. regulated and partially concentrated one it is possible to generate more quantities of energy from weaker and medium winds. As a result, their efficiency will be multiplied. This article will describe and show the basic elements of aerodynamical construction, stators profiles and control blades of new wind turbines, mechanism of automatic stator regulation (beside rotor regulation) as well as modified diagram of raised medium wind speeds. power calculations and diagrams are showing that new wind turbines in nozzle, of the same diameter of rotor and at same wind speeds, due to aerodynamic activity of nozzle and 'square-cube' relation in that transformation are giving 4,3 times more electric energy than the standard types. The wind speed on rotor is raising according to square of outer diameter (dv2) of stator mantle while power of new turbine in nozzle is growing with cube (v3) of raised speed for normal working area. The costs of construction and operation will rise like speed according square of diameter while the production and profits, like the power, are growing with cube of raised speed. (author)
