Briefly, the design uses two rotors on the same shaft rotating in the same direction. A right-angle drive in the nacelle turns a drive shaft to transmit power down tower to 11 MW of generators mounted at the base of the turbine.
GE introduces smart, powerful 2.75-120 wind turbine
Today at the European Wind Energy Association’s annual conference, GE announced its 2.75-120 wind turbine, a smarter, more powerful turbine. Part of GE’s brilliant wind platform, the 2.75-120 provides 5% more annual energy production than GE’s 2.5-120 model and is available with various tower technologies, ranging between 85-139 meters, and optional energy storage. The 2.75-120…
Twin rotor 11-MW turbine closer to physical prototype
About a year ago this magazine reported on the design completion for a twin-rotor turbine that its developer boasted was capable of generating 11 MW. The Airgenesis turbine (airgenesiswind.com) sports other innovations, such as using a shaft to transmit power down tower to several generators arranged in a circle at the tower base. Twelve generators,…

New thinking in turbine design
A novel turbine design uses two rotors of equal diameter, one each at opposite ends of a nacelle, to capture wind at greater capacity factors than conventional designs can do, say developer Airgenesis LLC (airgenesiswind.com). The developer says the rotors, offset from each other by 60°, will be turning at low speeds of 2.5 to…
