Abstract
This paper extends earlier work by the authors to include effects of coupled rotor-tower motions on aerodynamic control of fluctuating loads on lightweight HAWTs. The purpose of these investigations is to assess the effectiveness of this type control in closed-loop actuation to increase structural fatigue life. The present study considers a light-weight teetered rotor mounted atop a 'soft' towercantilevered at its base, and attention is focussed on coupled flatwise motions. The fiberglass rotor blades have full-span pitch control. The primary concern is the control of fluctuating loads due to turbulent winds during rotor operation.
