The houses the and generator connecting the tower and rotor. Sensors detect the wind speed and direction, and motors turn the nacelle into the wind to maximize output. In conventional wind turbines, the blades spin a shaft that is connected through a gearbox to the generator. The gearbox converts the turning speed of the bla. The hollow, wide-chord fan blade allows higher flow, higher efficiency, and is quieter than its predecessor, the snubbered blade. [pdf]
What is a wind turbine? A wind turbine, or wind generator or wind turbine generator, is a device that converts the kinetic energy of wind (a natural and renewable source) into electricity. Whereas a ventilator or fan uses electricity to create wind, a wind turbine does the opposite: it harnesses the wind to make electricity.
Join Our Community of Science Lovers! The differences between wind turbine and ceiling fan blades arise from the contrasting design criteria: the wind turbine is intended to capture high-velocity wind to generate electricity efficiently; the ceiling fan needs to move air at low velocity with inexpensive components.
With this in mind, the blades of a wind turbine are designed much like an airplane’s wings. The rear of the blade is curved more than the front, the same way a plane’s wing curves upwards at the end. This varied shape causes a pressure differential when the air moves across the blade, which is what causes the blades to move.
The pitch system can also "feather" the blades, adjusting their angle so they do not produce force that would cause the rotor to spin. Feathering the blades slows the turbine's rotor to prevent damage to the machine when wind speeds are too high for safe operation.
Most turbines have three blades which are made mostly of fiberglass. Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field.
The same thing happens in a wind turbine, only the "dynamo" generator is driven by the turbine's rotor blades instead of by a bicycle wheel, and the "lamp" is a light in someone's home miles away. In practice, wind turbines use different types of generators that aren't very much like dynamos at all.
