Keywords: nonlinear aeroelasticity, wing aeroelasticity, harmonic balance method

Nonlinear aeroelastic analysis of swept wings with 2dof in compressible flow was performed. Two applied method for obtaining LCO amplitude and frequency are in good agreement with each other. On the other hand, the accuracy of HB method increases by increasing of its order, as compared to the numerical solution.
