How Do Wind Turbines Work? | Sciencing

The main body of a wind turbine is the nacelle, which houses the generator as well as a series of drive gears.The blades are attached to the shaft, and the nacelle sits atop a tower that is as tall as possible to allow the blades to catch the maximum amount of wind. The nacelle also houses a controller that receives data from an anemometer, which measures wind speed, and a vane, which measures ...

Horizontal Vs. Vertical Wind Turbines | Education - Seattle PI

To work properly, the horizontal-axis turbine needs the wind to flow at a right angle to the blades. If it blows from a different direction than the blades are facing, the turbine gets much less energy from the wind.

Windmill vs. Wind Turbine - Polaris America

The windmill is a much shorter machine then that of a Wind Turbine. The Wind Mill uses more blades to catch more wind power thus causing more physical work to be produced. The blades are generally connected to an axle and then lead to the gears of a pump or that of a grinding wheel to help generate erigation for crop production.

Windmill vs. Wind Turbine - wind.jmu.edu

Another key difference between windmills and turbines is that turbine blades operate on the principles of lift and drag, similar to that of airplane wings. As wind passes over an airfoil shape, a high and low pressure area form, causing lift, or in the case of wind turbines, causes the blades to rotate.
