Three-dimensional aeroelastic effects in the transonic flight regime can be analyzed by combining high-fidelity 3D CFD solutions with structural finite element models containing a large number of degrees of freedom. This combination is computationally expensive and is impractical in the preliminary design phase. Here, a non-linear vortex-lattice method that couples 2.5D transonic CFD solutions is examined. As such, it provides adequate precision for the study of three-dimensional aeroelastic effects at the computational cost of a VLM solution. This paper presents the combination of this method with a finite element beam model and demonstrates that this inexpensive method is suitable for the prediction of wing behavior in the transonic regime.
