A survey of panel aeroelasticity in shock-dominated flow: Perspectives from fluid-structure interactions and shock wave-boundary layer interactions

As a multidisciplinary phenomenon, panel aeroelasticity in shock-dominated flow is featured by two primary interactions: Fluid-Structure Interactions (FSIs) and Shock-Boundary Layer Interactions (SBLIs). The former raises structural concerns, and the latter is of aerodynamic interest. Thus, panel aeroelasticity in shock-dominated flow represents a vital topic for the development and optimization of supersonic vehicles and propulsion systems. This review systematically summarizes recent advances in the methodologies applied to capture structural and fluid dynamics, including theoretical models, numerical simulations, and wind tunnel experiments. The application of data-driven modal decomposition, an advanced technique to extract physically crucial features, on the topic is introduced. From the perspective of FSIs, the distinctive aeroelastic behaviors in shock-dominated flow, including hysteresis phenomena and nonlinear responses, are highlighted. From the perspective of SBLIs, the modifications in their spatial and temporal characteristics imposed by the aeroelastic responses are emphasized. Motivated by the interaction between the shock waves and structural response, different strategies have been proposed to implement aeroelastic suppression and shock control, which have the potential to enhance structural safety and aerodynamic performance in the next generation of high-speed flight vehicles.
