文档介绍：Low Wind Speed Technology Phase I: Clipper Turbine Development Project
Clipper Windpower Technology, Inc.
Project Description: Design studies conducted by the . Department of Energy, its
subcontractors, and others have indicated that several new design configurations offer
significant opportunities for reducing cost over current wind turbine configurations.
These technologies include reduction in the cost of and improvements in the efficiency
of the drivetrain; increases in energy capture by increasing rotor diameter; and
improved active wind turbine controls. Several techniques can be used to achieve
these results. Many, such as decreasing drivetrain weight to make taller towers more
cost effective, or advanced rotor designs that decrease loads and allow greater rotor
diameter, are interrelated.
This project is developing a new turbine design that incorporates a number of advanced
