This report describes a low budget flutter model incorporating active aerodynamic controls for flutter suppression studies, concentrating on the interfering lifting surface flutter phenomenon in the form of a swept wing-tail configuration. A flutter suppression mechanism was first demonstrated on a simple semi-rigid three degree of freedom flutter model of this configuration employing an active stabilator control. These preliminary studies were extended to the analysis of a larger degree of freedom AFFDL wing-tail flutter model. The analytical and experimental design of a flutter suppression system for the AFFDL model is presented along with the results of a preliminary passive flutter test. Author
