What is the differeance between upwind and downwind turbines?
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.
What are the two types of brakes on a wind turbine?
The controller and mechanical brakes.
Do yaw bearings teeth point outward or indward on a wind turbine?
yes
The turbine which rotates in only one direction whether the flow of wind is in either direction what is the name of this turbine?
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
What is electric turbine?
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.
What does a wind turbine make?
A wind turbine makes wind for scientific study.
What does wind turbine help?
a wind turbine generates electricity for or use
What does Wind Turbine mean?
A wind turbine is like a giant fan that produces energy from the wind
What makes a wind turbine move?
Wind makes the turbine move and the wind makes elctrecity.
How is wind created in a wind turbine?
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 :)
How a wind power system produce electricity?
The wind turns a wind turbine. The turbine turns a generator.
What is another name for a wind tower?
Another name for a windmill is the wind turbine
How can you generate power using a mini wind turbine?
To generate power using the mini wind turbine you will have to install a small wind turbine and connect it to the grid.
What does a wind turbine look like?
a wind turbine looks like a giant fan
How is a wind turbine a example of mechanical energy?
This is so because when a wind turbine turns or spins it exerts wind
How do you make a wind turbine in alchemy classic?
Active Robot + Metals + 2 Wind = Wind Turbine
How much wind can one wind turbine generate in one year?
A wind turbine is not designed to generate wind, it uses wind and generates electricity.
