A status report on a model for Benchmark active controls testing

This 'work-in-progress' paper presents a status report on an active controls flutter model which is currently in the design and fabrication phase. This model is a part of the Benchmark Models Program (BMP). The BMP is a NASA LaRC program that includes a series of models which will be used to study different aeroelastic phenomena and to validate aeroelastic methods. The objective of Benchmark Active Controls testing is to validate active control design tools. Flutter testing will be conducted with a pressure-instrumented rigid model attached to a flexible pitch and plunge mount system. Unsteady pressure distributions and transonic flutter boundaries will be measured with and without active control system engaged.
