A team of researchers from the University of Virginia, Sandia National Laboratory and the National Renewable Energy Laboratory has developed a giant lightweight wind turbine blade longer than two football fields, which will help build offshore wind turbines
with a power of 50 megawatts.
Todd Griffiths, lead designer of Sandia National Laboratories' offshore wind blade project, said the super wind turbine takes advantage of economies of scale
.
The U.
S.
has huge offshore wind potential, but offshore installations are expensive, so larger turbines are needed to capture energy to be able to afford them
.
Griffiths pointed out that traditional windward blades for 10 MW to 15 MW wind turbines are expensive to build and must be tough to avoid fatigue or downtime in strong gusts
.
These blades are very heavy, and the greater the mass, the higher
the cost.
According to the Physicists Organization Network recently, the design of the newly developed giant wind turbine blades was inspired by the way
palm trees sway in storms.
The blade is designed to be assembled by a small section of blade joint, and its lightweight segmented torso is equivalent to a series of cylindrical shells, which can make the entire blade bend in the wind while maintaining the hardness of each blade, which fundamentally reduces the requirements
for blade hardness.
And due to segmented manufacturing, production and installation costs are greatly reduced
.
When a dangerous hurricane hits, the giant blades are retracted to align with the wind direction, reducing the risk of
damage.
At lower wind speeds, the blades unfold to maximize
the energy generated.
According to the recent Wind Vision Report in the United States, wind energy should account for 20%
of the total energy of the United States by 2030.
The development of giant wind turbines will be an important means to
achieve this goal.
