Abstract This study has established a reduced order model (ROM) based on spectral proper orthogonal
decomposition (SPOD) method in order to proceed an aerothermoelastic response analysis of a
hypersonic panel. The two-way coupling between aerothermal and aeroelastic systems is applied
[1]. Three aspects of POD-ROM are investigated: 1) the selection of snapshots for POD modes; 2)
the comparison between classical POD [2] and SPOD [3]; 3) how to find global POD modes in a
parameter space of flight altitude and Mach number. The snapshots are sampled from
aerothermoelastic response data via the classical Galerkin method. The… More >
