Aerodynamic problems explained

For a wind turbine to produce energy, the wind must be able make the rotor turn by flowing cleanly around the blades. The longer the airflow stays attached to the blade, the more lift force and therefore energy is generated.

If the airflow separates from the blade surface, turbulence occurs along the trailing edge. This is called ‘aerodynamic stall’ and results in decreased lift, as illustrated in the videos above. The more airflow separation, the further the stall point moves towards the leading edge, and the less lift force is generated.

This is why the majority of the blade is shaped like an aircraft wing. These thin airfoils are aerodynamically optimal and facilitate the best possible lift and energy production.

The inner part of nearly all turbine blades is characterized by thick airfoils. This is a necessary production compromise, as shapes must transition from thin airfoils to a circular geometry at the root, where the blade is attached to the turbine hub.

The result is suboptimal aerodynamic properties – in other words, the airflow in this area is unable to stick to the blade for as long as desired. Instead, the airflow separates from the blade surface, or ‘stalls’, resulting in suboptimal energy production.

The outer part of the blade is designed for optimal aerodynamic performance. But this part of the blade travels at very high speeds (200-300 km/h), meaning that rain, hail, bugs, sand and other particles inevitably erode or cling to the blade surface over time.

The blade surface will gradually degrade as the wear and tear takes its toll, ultimately causing erosion along the leading edge. As a result, the aerodynamic properties of the blade are jeopardized, and power production declines.
