An Upwind turbine faces into the wind with the turbine blades in front of the Nacelle* while a Downwind turbine has blades to the rear of the Nacelle and faces away from the wind. Up-wind turbines are by far and away the most common, but down-wind turbines (usually two-bladed) are also used in certain situations.In very strong winds the turbine blades of a wind turbine generator flex under enormous forces. With a down-wind turbine the blades flex AWAY from the mast which prevents them from crashing into it. Up-wind turbines need to be designed so that the blades are positioned at a good distance from the mast, and they must also be engineered to be inflexible (which costs more money). In addition, when the blades of a down-wind turbine bend it reduces the stresses on the mast as wind energy is lost in bending the blades. Finally, down-wind turbines do not need a tail (or motorised yaw mechanism) to align them with wind as the turbine blades perform this task (although this can also be a serious disadvantage in large down-wind turbines if wires carrying huge currents are getting twisted).Down-wind turbines on the other hand are generally noisier (additional aerodynamic noise), and the blades are subject to more forces than those of up-wind turbines. Another serious disadvantage of a down-wind turbine is wind shadow behind the mast causing a drop in power each time a blade passed behind the mast.*Nacelle = is located at the top of the mast and contains the rotor and generator, and sometimes a gearbox. Basically it is everything except the turbine blades, tail, and mast.
The controller and mechanical brakes.
yes
i have got a pic of such turbine this is designed by some engineering studentshere is the picturehttp://www.engin.umich.edu/dept/name/research/projects/wave_device/picture005.jpg
An electric turbine in a large machine that has the ability to extract raw energy through wind, water, or other such natural source and convert it into a workable form of energy. One example of electric turbines at work can be seen with windmills.
A wind turbine makes wind for scientific study.
a wind turbine generates electricity for or use
A wind turbine is like a giant fan that produces energy from the wind
wind is not created by the turbine but wind that passes through the turbine causes it to turn, and the faster the turbine spins the more energy is created that can be turned into electricity and other resources. Hope This Helps :)
Another name for a windmill is the wind turbine
A wind turbine moves when the wind blows against its blades, causing them to rotate. The rotation of the blades drives a generator inside the turbine, converting the kinetic energy of the wind into electrical energy.
Wind power.
a wind turbine looks like a giant fan
This is so because when a wind turbine turns or spins it exerts wind
Active Robot + Metals + 2 Wind = Wind Turbine
A home wind turbine will use the power of wind to provide and generate energy. One can use a home wind turbine at home to provide electricity or heat water, for example.
The inventor of the wind turbine was Charles F. Brush in 1888.
