What is it about?
Rockets, fighter jets, and other high-speed flight vehicles encounter severe aerodynamic forces during flight. If the outer wall is made too thin, certain geometric obstructions on the vehicle (such as a fin or control surface) can lead to catastrophic failures. These conditions are investigated in this paper in an experimental study.

Why is it important?
The phenomena are very complicated and therefore cannot be easily simulated with computers. For this reason experimental results are at the foundation of understanding how to design the outer hull of high-speed flight vehicles, such as missiles.
Perspectives
This study adds experimental data of both the surface pressure and vibration of a canonical structure (fully clamped panel) to the existing body of knowledge. It further shows a process to characterize whether the panels are in a dynamically unstable (flutter) state as opposed to a forced vibration state, which is commonly not done in experimental research of this type.
