Chinese OEM unveils the world's longest onshore wind turbine blades

www.notebookcheck.net Chinese OEM unveils the world's longest onshore wind turbine blades

At 430 feet (131m), the SY1310A is the latest engineering feat from Sany Renewable Energy that sets the record for the world's longest wind turbine blades on land. The company intends to deploy the blades on its 15 MW turbines, which are set to be the most powerful onshore wind turbines around.

Durability is the chief concern for wind turbines, and it becomes increasingly difficult with the size and scale of the blades. Courtesy of a thicker airfoil, a reinforced carbon fiber main beam and a metal mesh for lightning protection, Sany's SY310A blades are built to last. And although they aren't 100% recyclable, the trailing edge insert is made of recycled polyurethane structural parts that can be easily circulated after the lifespan of the turbine.

The blades are 131 m for those wanting to save a click.
- Thank you!
They broke the record again!
why this matters:

Larger rotor diameters allow wind turbines to sweep more area, capture more wind, and produce more electricity. A turbine with longer blades will be able to capture more of the available wind than shorter blades—even in areas with relatively less wind. Being able to harvest more wind at lower wind speeds can increase the number of areas available for wind development nationwide.
Why? I thought they were coming up with better designs that worked with smaller blades
