OVERVIEW ATA has developed a high-fidelity, tightly integrated multiphysics analysis capability for performing coupled aerothermal-structural simulation of hypersonic vehicle structures. ATA’s methods leverage a set of coupled software tools created to model the response of these structures in extreme flight environments at both the global level of the full flight vehicle and the local level of critically loaded vehicle skin panels. The approach improves upon traditional uncoupled methods by integrating a hypersonic-capable computational fluid dynamics (CFD) code with a nonlinear computational structural dynamics (NLCSD) code in a fully coupled fluid- structure interaction form.
