Load Consequences when Sweeping Blades - A Case Study of a 5 MW Pitch Controlled Wind Turbine
Open access wind tunnel measurements of a downwind free yawing wind turbine
A series of free yawing wind tunnel experiments was held in the Open Jet Facility (OJF) of the TU Delft. The â 300 W turbine has three blades in a downwind configuration and is optionally free to yaw. Different 1.6m diameter rotor configurations are tested such as blade flexibility and sweep. This paper gives a brief overview of the measurement setup and challenges, and continues with presenting some key results. This wind tunnel campaign has shown that a three bladed downwind wind turbine can operate in a stable fashion under a minimal yaw error. Finally, a description of how to obtain this open access dataset, including the post-processing scripts and procedures, is made available via a publicly accessible website
