“…The agreement between experiment and the two theoretical models is very satisfying and suggests a good fundamental understanding of the flutter phenomenon for M < 5. Later experiments and computations by Vedeneev [33] suggested that single degree of freedom flutter in higher panel modes may also occur when great efforts are made to minimize the boundary layer thickness and the structural damping as well.…”

Hypersonic flight is a major technical challenge and substantial efforts are currently underway to provide the understanding and technology required to design and operate effectively and safely a hypersonic aircraft for commercial or military purposes. Leyva [1] has recently described the essence of this challenge. The present chapter provides a summary of the past, present and proposed work for fluid/structural/thermal dynamics interaction.

“…It was also shown that the instability domain consists of a coupled flutter domain and single-mode flutter domains for various modes and that single-mode flutter significantly extends the instability domain towards the region of small Mach numbers and short plates. The influence of the boundary layer [26], as well as of the structural damping of the plate [27] was studied as well, and the limit cycles of nonlinear flutter vibrations were analyzed [28,29]. Finally, experiments were performed [30], where single-mode flutter excitation for Mach numbers in the interval 1 < M < 1.3 was registered for the first time.…”

It is assumed in all classical studies of panel flutter that the unsteady pressure of a gas flow can be calculated according to the piston theory. But the piston theory holds only for large Mach numbers and does not cover the region 1 < M < 2. It was recently shown that, in this range of Mach numbers, there is a region of panel flutter, referred to as single-mode flutter, which differs from the "classical" (coupled) flutter. In the present paper, single-mode flutter is studied numerically for a strip-shaped periodically supported plate. The boundaries of stability are constructed, and the influence of the strip width and the distance between the supports is analyzed.
