Why 2-Blade?

Even though 2-Blade technology is currently less visible in the wind power sector, the development project that created GC China Turbine Corp.'s technology has been operating for 10 years with 98% electrical generation availability. Furthermore, the GC China technology benefits include lower manufacturing cost, lower installation cost and lower operational costs. GC China Turbine Corp. products are uniquely superior to the current commercial designs.

The 2-bladed wind turbine is manufactured utilizing a number of complementary technologies incorporating engineering innovations such as independent blade and tower flexibility delivering revolutionary overall load damping characteristics, a highly compact and lightweight transmission system and proprietary real-time, reactive monitoring technologies. These key elements combine to reduce vibration and overheating, lower installation and transportation costs, improve service life and extend the generated output lifecycle of the product. The resulting benefits deliver where it counts…  high quality and lowered costs from manufacture to installation and maintenance.

GC China's “Soft Technology” combines a passive yaw system, “teeter” style hub, and a flexible, lightweight “soft” tower. By using the integrated Soft Technology as a damping system to manage vibration and system loads, GC China Turbine Corp. can produce a transmission chain that isn’t required to absorb these massive forces. Therefore, the proprietary Transmission Chain is significantly simpler and compact, cheaper and inherently more reliable than other current commercial designs in the rapidly growing mega watt  turbine class.
