The SWRT test has provided modelers with a unique data set to help the small wind turbine community understand small wind turbine behavior. A better understanding of small wind turbine dynamics, including furling and thrust, was a result of the test. Analysis of the SWRT test data shows the complex interaction of thrust, center of thrust, yaw rate, RPM, and how these variables relate to furl. The SWRT data sets provide a unique set of data for validating aerodynamic models for a turbine that operates at a significant yaw error, has high yaw rates, is in and out of stall quickly, and operates at higher RPMs. Analysis and comparison of FAST and ADAMS model simulations and test data for the SWRT has resulted in a better understanding of small wind turbine modeling, as well as a FAST furling model that can be used by engineers to better design small furling wind turbines. The SWRT modeling has shown the importance of including blade torsion in the modeling, which can only be done with the ADAMS model at this time. Future changes to the FAST model should include the ability to model blade torsion.
