According to the wind tunnel test data of the large-amplitude motion,the algorithm to solve fuzzy-logic model using in unsteady aerodynamics model in the recent years was modified,to increase the speed of modeling and the precision fo the model.

The special additive unsteady aerodynamic using in T-tail flutter is investig.

<Abstrcat>　In order to satisfy the calculation need of Electrical Controlled Rotor(ECR, or so-called swashplateless rotor), a synthetic unsteady aerodynamic model in time domain is presented to predict the aerodynamic force and moment of the airfoil with a trailing-edge flap.

Based on the nature vibrational characteristics of the flat wing calculated by finite element method, generalized unsteady aerodynamic forces matrix induced by the wing deformation is gotten by using strip theory, and thus the flutter model equation of the single wing is given.
