  • The fuzzy logic models of unsteady aerodynamics were lucubrated. The system′s fuzzy logic models, structures and parameters identification and model establishment were researched. The new modeling method makes the models has more abroad practicability. With using the typical test data, fuzzy logic modeling of nonlinear unsteady aerodynamic was developed. First, two fuzzy logic models of unsteady aerodynamics of oscillating delta wing were developed. One model employs the reduced frequency, the other uses the incidence history to account for the unsteadiness of flow characteristics. It was shown that both model results agree with the experimental values. Second, these two fuzzy logic models were used to simulate the typical post-stall Cobra maneuver, and the applicability of these two fuzzy logic models were demonstrated.
