A systematic parametric investigation of the flutter behaviour of the annular wing in inviscid incompressible flow is performed. The aerodynamic model for the calculation of the motion-induced unsteady airloads in terms of related aerodynamic coefficients, applying a higher- order panel technique, is explained. The aeroelastic stability equations are derived in non-dimensional form and the procedure used for the numerical solution of these equations is outlined. Numerical results are presented for a variety of systematic parameter variations, and overall trends in the aeroelastic stability of the annular wing and the effects of the dominant parameters are pointed out.
