A joint scientific research team in the United States recently announced a foldable, modular fan impeller design. The wind turbine unit using this design can be used for self-protection under severe weather conditions. It can be applied to large-scale generator fan wheels at sea. . The research team, led by Prof. Eric Loth, Department of Mechanical and Aeronautical Engineering, University of Virginia, includes researchers from the University of Illinois, the University of Colorado, the Colorado School of Mines, the National Renewable Energy Laboratory, and the Sandia National Laboratory. The team’s design is called the Segmented Ultralight Morphing Rotor (SUMR). The blades are mounted downwind and can be folded like palm leaves in dangerous weather conditions. Apply this. The design of the blade enables the realization of a maximum blade length while achieving light weight, and the segmented design allows the blade to be installed in the field. When the folded blade reaches its maximum length, a peak power of 50 MW can be emitted under strong wind blowing on the sea surface. If the traditional configuration is adopted, such long blades will be unexpectedly heavy, but in the new segmented structure design, the ultra-long blades can also achieve ultra-light structural quality. In the U.S. sea, there is usually huge wind power. However, if the conventional fan adopts a long blade design, it will not be able to withstand the wind strength and be destroyed. The new design has an adaptive design for dealing with bad weather. When subjected to high winds, it can bend downwind and bend, and can be fully retracted in a hurricane. To a minimum. The current research team has received US$3.56 million in funding from the Advanced Research Projects Agency (ARPA-E) of the US Department of Energy. The research team will work hard to promote the commercialization of the new design.
