Sep 27, 2017

Horizontal axis wind turbines can be divided into lift type and resistance type. Lift-type rotation speed, resistance type rotation speed is slow. For wind power, the use of lift-type horizontal axis wind turbine. Most horizontal axis wind turbines have a windshield and are able to rotate as the wind changes. For small wind turbines, this type of wind rudder is used for wind turbines, and for large wind turbines, winds are used as sensors and servo motors.

Horizontal axis wind turbine model

Horizontal wind turbine style a lot, and some with a reverse blade of the wind wheel; some in a tower to install a number of wind wheels, in order to output power under certain conditions to reduce the cost of the tower; some use of conical cover, So that the air flow through the horizontal axis of the wind when the concentration or spread, so accelerate or slow down; there are horizontal axis wind turbine in the wind around the whirlpool, concentrated airflow. Increase airflow speed.

Horizontal axis wind turbine characteristics

1, start the wind speed is low, high wind energy utilization; small size, good looks, low operating vibration.

2, the installation of user-friendly design, convenient equipment installation, maintenance and repair.

3, the wind wheel blade using a new technology by precision injection molding, coupled with the optimization of aerodynamic shape design and structural design, high wind energy utilization factor, an increase of annual power generation.

4, the generator using patented permanent magnet rotor alternator, coupled with a special stator design, effectively reduce the resistance torque of the generator, while the wind wheel and the generator has a more good matching characteristics, the unit running reliability.

5, the use of maximum power tracking intelligent microprocessor control, effective regulation of current and voltage.

Horizontal axis wind turbine blades are currently made of composite materials. Because the composite material has the characteristics of light weight and high strength ratio, the wind turbine blade can bear the bigger aerodynamic load. Based on Tsai-Wu strength theory, the characteristics of the laying fiber direction on the blade root, the airfoil transition zone and the airfoil area strength performance were studied. The results show that the 45 ° laying fiber direction exhibits the optimal intensity in the vicinity of the geometric mutation performance. Li Rennian set up several sets of pavement program for leaf modal analysis and found that increasing the thickness of the beam cap to make the first-order natural frequency of the blade slightly increased, the relative displacement of the blade also reduced a lot. ZHAO Xu The finite element method and the laminated plate model were used to analyze the fan blades under the static strength of aerodynamic force, centrifugal force and gravity load. It was found that the fiber had the highest strength, the deformation and failure factors were the smallest along the tangential pavement The worst intensity.

Horizontal axis wind turbine wind wheel rotation axis is horizontal, and the ground and the wind direction is basically parallel. Figure 1 is a toy windmill, fixed in the windmill on the axle seat, axle in front of a hub, both connected through the windmill shaft, the wheel can be free to rotate around the wind axle. The windmill has six blades, the blades are fixed on the hub, the blades are perpendicular to the windmill axis, the angle between the blades is 60 degrees, the six blades and the wheels form the wind wheel, each blade 25 degrees (or Similar angle) of the tilt angle. When the wind axle and the wind parallel, the wind wheel will spin up.
