Exploring the response of a thin, flexible panel to supersonic turbulent flow and shock boundary-layer interactions(SBLI)

Abstract

There do not currently exist reasonable means to accurately simulate the complex and often nonlinear response of an aircraft structure to the dynamic, high-temperature and transient environment of high-speed flight. While methods do of course exist to predict aspects of the static and dynamic responses of such structures, once the response becomes nonlinear (geometric, material, etc.) and the transient nature of the loading requires a long time history, the simulation problem proves quickly intractable. As a consequence, predictive techniques rely on simplifying assumptions, oftentimes overlooking or losing the ability to capture extreme responses or local effects that lead to damage and failure.
