This paper presents flutter analyses of aircraft structures using an advanced aeroelastic formulation. Three-dimensional problems are reduced to refined 1D structural models based on the Carrera Unified Formulation. Aeroelastic results are obtained by coupling the CUF structural model with the doublet-lattice method. Aeroelastic analyses on thin-wall and multi-component structures are proposed.
