Reduced Order Modeling for Hypersonic Aeroelasticity
Abstract
Hypersonic vehicles require structures to withstand complex non-proportional loading leading to path-dependent responses with interacting failure modes. This forces the analyst to consider margins over a trajectory instead of assumed worst-case points. Specifically, these structures will experience high transient surface temperatures and gradients from flow compression/viscous dissipation, broadband pressure fluctuations due to boundary layer turbulence, deformation induced pressures, and long-duration exposure to these environments. The modeling of such phenomena requires the coupling between the aero-thermal environment and the structural deflections and the consideration of local effects inherent in hypersonic flows. The computational cost associated to the resulting large models is often prohibitive and severely affect the design process.
