[Chinalco.com] The United States Crystal Finishing Systems and Lucid Energy Technology have worked closely together to successfully use aluminum extrusions for renewable energy - wind power. This innovative application made the two companies stand out in the financial crisis.

CrystalFinishingSystems' headquarters and factory are located in Schafeld, Wisconsin, USA. It is an independent soft aluminum extrusion company that provides aluminum extrusions for the construction and transportation industries. Lucid Energy Technology has successfully researched and developed the Görröll screw turbine and commercialized it. This is a patented new technology. The Gollov spiral turbine is used for running water or wind power.

Closer to CrystalfinishingSystems, Inc., Lucid Energy Technology Co., Ltd. helped squeeze the newly developed key component, the Air Wing, which converts wind energy into electrical energy. The Gorlov screw turbine is a new design of the vertical power generation turbine. The inventor was Dr. Alexander Gorlov, who designed the vertical shaft turbine with air wing blades. The air wing blades have spiral twisting. The spirally curved blades evenly distribute the cross-section of the wing during one rotation cycle, making the peak stress less, easing the torque, and finally achieving an effective conversion capability, low noise and low vibration characteristics, originally developed for the hydraulic flow of the water flow Power generation, and now the Golov Roller Turbine is designed for wind power generation. However, the air wings of wind power generation are much larger than those of hydropower generation. The wind-powered Golov Roller Turbine is 6 meters high and more than 3 meters in diameter.

The Air Wing Blade is a complex multi-cavity hollow aluminum extruded section designed to require high performance and long service life. All air wing blades must have the same wall thickness, twist and twist strength, and Lucid Energy Technology has no choice for compounding. Instead of materials, aluminum extruded profiles are used, made of 6061-T6 aluminum extrusions.
