Abstract

At the National Renewable Energy Laboratory, we tested a very flexible wind turbine. This machine, the Cannon Wind Eagle turbine, exhibited an ability to significantly reduce the rotor flap-wise bending moments through a unique combination of a flexible rotor and hub design. In parallel to this testing effort, we developed analytical models of this machine using our simulation codes. The goal of this work was to validate the analytical models of this machine by comparing analytical predictions to measured results from the real machine. We first describe briefly the simulation codes used in this study. We then describe the wind turbine we analyzed. We then describe analytical model validation progress for this flexible rotor and show preliminary validation results.
