FUNCTION OF WIND TURBINE BLADE
Wind flows over a propellers blades it creates lift and makes them turn. But there's more to it than that. Making electricity from wind actually involves a two-step process. A wind turbine converts energy from wind into mechanical energy. This is done as the blades on the turbine turn a drive shaft. The drive shaft is connected to a generator that converts the mechanical energy into electricity, according to the U.S. Environmental Protection Agency. A wind turbine requires maintenance twice a year, advises the EPA. A well-maintained turbine will last about 20 years.
Wind energy turbines are broadly classified into two varieties namely, the horizontal-axis type and the vertical-axis type. The classification is based on the orientation of the axis around which the turbine rotates. The horizontal wind turbine rotates around a horizontal axis and is the common variety largely used to generate electricity. A horizontal-axis turbine mainly consists of a rotor shaft, two or three blades and an electric generator. The blades are pointed in the direction of the wind. The movement of the blades moves the shaft mechanically and the generator connected to the shaft uses this mechanical energy into electricity. Thus the electricity produced is directly proportional to the speed of wind, rather the speed of the propeller blades. Some advanced wind energy turbines use a gearbox to turn the slow rotation of the blades into a faster rotation to ensure an efficient driving of the electrical generator. Wind turbines that are mounted on a high tower, say hundred
