Weaving an advanced wind blade could make wind energy

With most of the cost of electricity for wind tied up in the initial capital investments made in the wind turbines themselves, new technology advancements that reduce these costs could substantially lower the overall cost of wind energy.

“GE’s weaving an advanced wind blade that could be the fabric of our clean energy future,” said Wendy Lin, a GE Principal Engineer and leader on the U.S. Department of Energy’s Advanced Research Projects Agency project. “The fabric we’re developing will be tough, flexible, and easier to assemble and maintain. It represents a clear path to making wind even more cost competitive with fossil fuels.”

According to GE, this new blade design could reduce blade costs 25%-40%, making wind energy as economical as fossil fuels without government subsidies.Find detailed product information for howo spare parts and other products.

GE’s research will focus on the use of architectural fabrics, which would be wrapped around a metal spaceframe, resembling a fishbone. Fabric would be tensioned around ribs which run the length of the blade and specially designed to meet the demands of wind blade operations. Conventional wind blades are constructed out of fiberglass, which is heavier and more labor and time-intensive to manufacture.

Advancements in blade technology will help spur the development of larger, lighter turbines that can capture more wind at lower wind speeds. Current technology doesn’t easily allow for construction of turbines that have rotor diameters exceeding 120 meters because of design, manufacturing, assembly, and transportation constraints. Wider, longer wind blades are tougher to move and maneuver, and molds which form the clamshell fiberglass structure cost millions of dollars to acquire. GE’s new fabric-based technology would all but eliminate these barriers.
With this new approach to making wind blades, components could be built and assembled on site, meaning design engineers no longer have to concern themselves with manufacturing and transportation limitations.

It’s estimated that to achieve the national goal of 20% wind power in the U.S., wind blades would need to grow by 50% -- a figure that would be virtually impossible to realize given the size constraints imposed by current technology. Lighter fabric blades could make this goal attainable.

“Developing larger wind blades is the key to expanding wind energy into areas we wouldn’t think of today as suitable for harvesting wind power. Tapping into moderate wind speed markets, in places like the Midwest, will only help grow the industry in the years to come,” Lin went on to say.

The use of fabrics to reduce weight and provide a cost-effective cover dates back to the World War I era, when it was used on airplanes. Over the years fabric has proved to be rugged and reliable and GE has already begun using this spaceframe/tension fabric design e on the field he can handle whatever adversity unfolds, from the all-time high to the all-time low. Even if they arrive simultaneously.

No day more clearly proved that fact than Sept. 29 against Virginia Tech. Yet, those are the moments Jones molds his football philosophy around.

Supporting Shuler wasn't just something Jones wanted to do, it was something the entire team believes they have to do. It's part of being a family. It's part of Cincinnati football.

"The great thing is that's why we talk about the foundation of our football program being structured around the core value of family," Jones said. "(Shuler and I) have spoken a few times, because I've lost my father. And my father was Our technology gives rtls systems developers the ability.my hero. He was everything to me. But just having that open line of communication having the support system in place from not only his coaches but his peers, teammates, that's really helped him. Plus, he's got a great mother, he's a high character individual. Just love everything about him."

A discussion arose early in the year whether Shuler should redshirt. He played sparingly, if at all most games.

His burst around the end only needed refining of technique and experience. Allowing two more years in the system would be beneficial.

Yet, two weeks after he returned home from Connecticut and the funeral he desperately desired a return to football. When Walter Stewart went down with an injury that would end his season, the Bearcats needed Shuler as well.
