# What is the chord length of a wind turbine blade?

## What is the chord length of a wind turbine blade?

To calculate chord length, plug numbers into the following equation: Blade Chord (in meters) = 5.6 x R^2 / (i x Cl x r x TSR xTSR) Where: R = Radius at tip, r = radius at point of computation, i = number of blades, Cl = Lift coefficient and TSR = Tip Speed Ratio.

What is the length of wind turbine blades?

120 feet long
The blades of the wind turbines are 120 feet long so that the total height from the ground to the tip of the blade is more than 380 feet, approximately the height of a 32-story building. 2. How fast do the blades turn? Depending on wind conditions, the blades turn at rates between 10 and 20 revolutions per minute.

Should wind turbine blades be long or short?

When it comes to wind turbines, bigger is definitely better. The bigger the radius of the rotor blades (or diameter of the “rotor disc”), the more wind the blades can use to turn into torque that drives the electrical generators in the hub. More torque means more power.

### What is chord length of blade?

A turbine with a larger chord length has a higher torque curve when the chord length is smaller than 550 mm. However, further increasing the chord length will lower the torque curve….ABSTRACT.

What is the chord of a blade?

A straight line joining the leading edge of a propeller blade with its trailing edge.

Why are wind turbines bad for the environment?

As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitat for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.
