THE THREE MAIN PARTS OF A WIND TURBINE

  • Rotor blades
  • Gear box
  • Generator

How Rotor Blades Work

  • Take energy from the wind
  • They "capture" the wind and turn it in rotation of the hub
  • They use the same "lift" system
  • First there below the wing
  • Second stream of air produces, over pressure
  • Third it's above the vacuum wings
  • It has 3 blades
  • Horizontal axes
  • Diameter of 40 to 90

Gear Box

  • Connects low-speed shaft to a higher speed to increase that retains the speed to 30-60 rotations per minute that's about 1,000 to 1,800 rpm.
  • You need 1,000-1,800 that's the speed required to produce energy
  • The gear box is costly and heavy
  • Part of a wind turbine is when engineers explore "direct-drive" but that generates lower rotation speed not gear boxes

Generator

  • Produces 60-cycle AC electricity
  • Converts mechanical energy into electrical energy
  • Spinning blade of a wind turbine are connected to a spinning rotator and generator
  • Useful in areas with a lot wind
  • Safer then fossil fuels
  • Can provide electric power machines, homes, large buildings, and entire cities

Wind Turbine Facts

  • 1 wind turbine ca power 500 homes
  • 95% of wind turbines are installed on private land
  • Iowa and South Dakota generated more then 25% of wind energy in 2013
  • On May 2014, the United States is home of 46,000 operating wind turbines
  • By 2030 the United States would save 30 trillion bottles of water
  • Americans wind power is worth $10 billion dollar industry
