   Abstract:
   The flutter and LCO behavior of a delta wing and a flapping model were studied theoretically and the results were compared to experiment. Nonlinear aerodynamic and nonlinear structural theories were used in the theoretical modeling of the two aeroelastic systems. The resultant data were analyzed in detail.
