boat wind turbines and make them facing the wind [3]. The number of blades of boat wind turbines is often 3. Three-bladed boat wind turbines can produce power at low wind speed and can be self-started by the wind. This paper is focused on three-bladed boat wind turbines with passive yaw motion.

Wind Farms A wind farm is a collection of wind turbines in the same location. Wind turbines are often grouped together in wind farms because this is the most economical
3.Types Of Wind Turbines There are two types of wind turbines. One is Vertical axis wind turbines and the other is horizontal axis wind turbines. We also know that there is sufficient wind to satisfy much of humanity's energy requirements - if it could be gathered effectively and on a large scale.
Used wind turbines are purchased by a variety of companies including traders, operators, developers, and engineering companies. Those who purchase used wind turbines may wish to sell the used wind turbine, use it, refurbish it, or remanufacture it. Trading websites give an indication of who buys and sells used wind turbines.

and optimization of wind turbines. Aerodynamic modeling also concerns the design of specific parts of wind turbines, such as rotor-blade geometry, and the performance predictions of wind farms. The aerodynamics of wind turbines is in many ways different from the aerodynamics of fixed-wing aircraft or helicopters, for example.
