    Abstract:
    An understanding of transonic flutter is often critical for high-speed aircraft development. A presentation of the transonic flutter velocity as a function of the Mach number and mass ratio is shown here to provide many advantages. Such a presentation offers new insights when comparing computational and wind-tunnel flutter results. The benefits of such a presentation are also evident in parameter studies. Finally, the subject of flutter similarity rules for airfoils of different thicknesses is also addressed.
