The most interesting finding is that
Some benign structural instabilities can be exploited so as to improve the stability boundary of hypersonic vehicle structures
This implies a new methodology to design ultra-light long-endurance hypersonic structures.
More highlights are the following:
Aerothermoelastic response of a 3D stiffened skin panel in hypersonic flow is studied. Near-real-time high-fidelity hypersonic aerothermoelastic simulation is achieved. Aerothermoelastic instability is effectively identified using a linearized approach. Snap-through does not necessarily cause the unstable response of a skin panel. Orientations of flow and stiffeners impact the aerothermoelastic stability boundary.
