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<br/>(OJF) of the TU Delft. The ≈ 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...
