摘要：
An experimental campaign is performed to the study of feedback lift control applied to a wind turbine blade. A 5-digit NACA profile whose trailing edge is rounded for circulation control purposes is used in combination with fluidic actuation. It is first shown in this article how the modified profile performs, in terms of aerodynamic forces, in both natural and manipulated cases. Then, the dynamics of controlled pressure (and thus lift) establishment is identified. A discussion is given on the speed of lift dynamics in comparison with previous studies and on its ability to overcome lift perturbations due to external perturbations. Finally, a feedback lift control experiment is performed showing the feasibility of such control in a wind turbine environment. (C) 2018 Elsevier Ltd. All rights reserved.
