Application of a Time-Accurate Aeroelastic Coupling Framework to Flutter-Constrained Design Optimization

Aerodynamic Shape Optimization with Time Spectral Flutter Adjoint

“…Zhang et al [20] formulate a time-accurate adjoint for flutter analysis with a high-fidelity Euler solver. Recently, Kiviaho et al [21] develop a time-accurate adjoint by matrix-pencil method. Leveraging the efficient harmonic balance solver, Thomas and Dowell [22,23] propose a harmonic balance adjoint for flutter.…”

CAD-based and CAD-free aerodynamic shape optimization of turbomachinery blade rows using the adjoint method

“…Later, the efficiency of this approach was greatly improved [122], which enabled the aerostructural optimization of aircraft wings [123]. In addition, the coupled-adjoint approach has been used in aerothermal problems [124,125], aeroacoustic design [126,127] and aeroelastic coupling for flutter-constrained optimization [128,129]. Finally, it is worth mentioning the work of Schwalbach et al [130], who performed an adjointbased multidisciplinary optimization of a radial turbine under structural constraints.…”
