Explore a Wind Turbine

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

6 FAQs about [Wind turbine blade diagram]

How big is a wind turbine blade?

Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases.

What are the aerodynamic design principles for a wind turbine blade?

The aerodynamic design principles for a modern wind turbine blade are detailed, including blade plan shape/quantity, aerofoil selection and optimal attack angles. A detailed review of design loads on wind turbine blades is offered, describing aerodynamic, gravitational, centrifugal, gyroscopic and operational conditions. 1. Introduction

What is the difference between upwind and downwind turbines?

Upwind turbines—like the one shown here—face into the wind while downwind turbines face away. Most utility-scale land-based wind turbines are upwind turbines. The wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.

What if a turbine blade has no pitch?

Were the blade to have no pitch (0 degrees), the moment in extreme winds would be 7386 kN-m. So long as we are able to pitch our blade, however, it is possible to keep even extreme winds from damaging the turbine blade.

How do you determine the shape of a wind turbine blade?

In order to determine the shape of the blade, we utilized a program developed by the National Wind Technology Center called WT_Perf. WT_Perf uses blade element momentum theory in order to approximate blade loading as well as the power output.

Do wind turbines use horizontal axis rotors?
