The biggest turbines at the moment have blades over 50 metres long. The rotor diameter is then over 100 metres long, longer than a football field.
Smaller home, or farm, turbines have blades up to 15 metres (50 feet).
The blade length varies depending on output. Typical commercial wind turbines generating around 600kw have blades of 20m.
you can find the approximate length of blades for your turbine if you know the required turbine output.
L=( P/(Cp*0.5*density*pi*(wind velocity^3)))^0.5
value of Cp < 0.59. usually for good turbines 0.45

∙ 9y agoWind turbine blades comes in different sizes. In, New York, a blade broke off a wind mill that was 400 feet tall. The blade was 150 feet long. In 2012, Siemens introduced turbine blades that are 246 feet long.

What does the shaft in a wind turbine do?
The shaft is the part that gets turned by the turbine blades. It in turn is connected to the generator within the main housing.
How much does it cost to maintain a wind turbine?
The cost to maintain a wind turbine is estimated to be about 2% of the original investment per year. The cost of a wind turbine is $50,000.
What is a turbine?
A device used to turn kinetic energy into electricity
What is a steam turbine diaphragm?
Steam turbine is comprising of stages, number and size of the stages depands upon the break horse power of the turbine. The stage has set of moving and fixed blades. The moving blades are attached to the rotor while the stationary blades is called Diaphragm. The diaphragm guides the steam to glide over the moving blades for producing rotary motion.
How does wind produce energy?
Most commonly through windmills. the wind pushes on a tilted blade causing it to rotate. A generator inside the windmill then truns the kinetic energy of the rotation into an electric current.u blow on it
How many feet wide is a wind turbine?
Wind turbine vary enormously in size from a small turbine on a boat with blades about two feet in diameter to large industrial 'wind farms' the blades of which are individually dozens of feet long
What are the blades on a wind turbine called?
Blades
What is a wind machine with blades?
A wind machine with blades is so called a wind turbine, or a windmill.
Does a wind turbine have to have 3 blades?
no
What are the parts of a wind turbine?
The base tower, the blades, the turbine.
How long and how thick are wind turbine blades?
Wind turbines blades are about 15 meters long (average wind turbine) The thickness of the blade depends on the length of the blade. The width is about 10% of the length, in this case, would be about 1.5 meters thick.
Can you build wind turbine blades out of balsa wood on a meter-high wind turbine that have an rpm of 8700?
yes
How many blades do most wind turbines have?
There are 3 blades3 blades on each turbine
What are wind turbine blades built from?
Newer blades are made of aluminum and composite materials
Why should wind turbine blades be light?
to allow the blades to begin rotation in low wind speed, heavier blades need higher wind speed to start them.
Why should wind turbine blades be very lightweight?
