The tail fin is a special design for small wind turbines.
Behind the small wind turbine design usually have a tail, its running effect has a direct impact on the unit, so, don't ignore the unique design of this part is the tail of small wind generators have what effect?
Actually, small wind turbine at the back of the tail is mainly to use, if the fan impeller swept surface and the wind is not vertical, so stern rudder is not the same on both sides of the airflow velocity, pressure is not the same, so the differential pressure under the action of force, can make the fan to make the swept surface is opposite to the direction of the wind, to keep the unit of time efficiency to meet.
But large wind turbine were not allowed to use this way, because the quality of the mainframe is quite big, if want to rely on differential pressure force to turn, the rear wing area will have to be very big, so they are used motor steering instead of a tail to the.
When the wind blows, small wind turbine at the back of the tail if there is a Angle and direction, it will be a tangential force, wheeled around the tower fan rotation, until and direction Angle of 0, so that it can automatically adapt to the direction of the wind.
It is with the design of this tail fin that the small wind turbine can realize the wind power utilization and realize the wind power generation. The wind direction can be measured by wind anemometer on both sides of the tail of a small wind turbine, so as to better control the operation of the unit.http://www.titanwindturbine.com/
