More Efficient Wind Turbine Blade Designed Date: March 20 ... and new "structural" airfoils have been incorporated at a smaller scale in 9-meter-long prototype blade being flight-tested at Sandia ...

Such high-efficiency energy conversion dictates the use of lift-type turbine blades, similar to airplane wings, of twisted and tapered airfoil shapes. The blade design creates a pressure ...

AMES, Iowa – In Hui Hu’s Iowa State University office, you can feel exactly what ice does to an airfoil. As he recently rolled through the slides describing his research using Iowa State University’s ...

In March, LM Wind Power’s 73.5-m blades became the first 70-plus-meter blades to be installed when Alstom inaugurated its 6-MW Haliade 150 direct-drive offshore turbine at Carnet in the Loire ...

Twin airfoil blades generate powerful winds in a new rooftop hybrid solar setup.; Powerful wind turbines work great in giant empty fields, but not on your roof.; Wind rushes between the airfoils ...

While we've already seen that large-scale wind turbine blades which are shaped like humpback whale fins can be more efficient, what works for big turbines doesn't necessarily work for little ones.

Wind turbine blades are considerably longer, but because they bend and deflect under their own weight, a robot would have to be programmed to work on the bigger blades section by section. The ...

Chinese wind turbine manufacturer Sany Renewable Energy has unveiled the world’s longest onshore wind turbine blade, a 131-metre behemoth to be used on the company’s 15MW turbines.

Building lightweight blades of greater length remains a primary focus for utility-size turbine manufacturers because investment in blade technology pays off: When installed on a 5 MW turbine owned by ...

The robot worked on a 5-meter-long blade segment. Wind turbine blades are considerably longer, but because they bend and deflect under their own weight, a robot would have to be programmed to work ...

The world’s largest-ever onshore wind turbine blades have been manufactured in China. At 131 metres in length, each foil would dwarf Big Ben or the Statue of Liberty. A hydrogen fuel revolution ...
