Constant Power, Helical Transverse-Axis Wind Turbine with Automated Variable Pitch, Variable Radius and Torque Control

摘要

A transverse-axis power turbine, such as a Vertical-Axis Wind Turbine (VAWT), which includes both computer-controlled variable pitch and variable radius aspects providing a means to optimize performance and match variable loads in real-time. When multiple units are established coaxially and fixed to a floating platform, a method is presented of producing near net zero torque from the turbines on the floating platform. The transverse-axis power turbine can utilize helical blades for improved performance, while still benefiting from the variable radius and variable pitch functionality.
