Application of unsteady aerodynamic methods for transonic aeroelastic analysis

Aerodynamic methods for aeroelastic analysis are applied to various flow problems. These methods include those that solve the three-dimensional transonic small disturbance (TSD) potential equation, the two-dimensional full potential (FP) equation, and the thin-layer Navier-Stokes equations. Flutter analysis performed using TSD aerodynamics shows that such methods can be used to analyze some aeroelastic phenomena. For thicker bodies and larger amplitude motions a nonisentropic full potential method is presented.
