An aeroelastic prediction framework in MATLAB with modularity in the quasi-steady aerodynamic methodology isdeveloped. Local piston theory (LPT) is integrated with quasi-steady methods including shock-expansion theory andthe Supersonic Hypersonic Arbitrary Body Program (SHABP) as a computationally inexpensive aerodynamic solver.Structural analysis is performed using bilinear Mindlin-Reissner quadrilateral plate elements. Strong coupling of thefull-order system and linearization of the modal-order system are implemented. The methodology is validated againstpublished experimental data in literature and benchmarked against Euler computation in the Edge CFD code. Theflutter dynamic pressure is predicted to within 10% of the experimental value for 140 times lower computational costcompared to CFD. Good agreement in other cases is obtained with the industry-standard ZONA7 and ZONA7U codes.
