Wind turbine VETAR 15

Vetar 15 is a larger than Vetar IO wind turbine which makes it more suitable for areas with lower wind velocities. Vetar 15 is a new, highly advanced, high energy yield, birds friendly, low noise and low vibration concept of HAWT. New features which make Vetar 15 couple of times more productive than conventional HAWTs are: 1. Advanced aerodynamics with 1.5 times air acceleration capability. 2. Two highly effcient contra rotating rotors with effciency up to 55.5% connected with two independent PM electro-generators. 3. Turbulence and thermal control system (TTCS) whichcan reduce turbulent loses up to 10%. TTCS is consisted of specially designed turbulence control ring,specially shaped and distributed electro-generator housingsupporters and turbulent separation control canards.Thermal control segment is highly effective cooling systemwhich include additional inner blades inside main rotors,as well as additional rotors inside electro-generators housingsfor air circulation, pressurization and ejection of heated airat the back of second electro-generator housing foradditional turbulence control.
