【 摘 要 】

An experimental capability developed for testing two-dimensional aerofoils while dynamically pitching is discussed. Key to the approach are a dynamic pitch system, the rapid prototyping of aerofoils, inexpensive time-resolved pressure measurements, the ability to capture flow-field structure, and the ability to add compliance to the system. In addition to describing the system components, examples of typical results for characterization and control studies are given. Use of the data is also demonstrated through comparison of the results from a simulation with those from an experiment under the same conditions. Future uses of this experimental capability are also discussed.
