Calculates the velocity at which rocket fins are likely to experience "flutter," the velocity beyond which catastrophic fin failure is probable due to aerodynamically induced undampened fin oscillation. Read the accompanying article "Calculating_Fin_Flutter_Velocity_Bennett-12-23.pdf" for guidance on how to use the spreadsheet.
The companion article "Calculating_Fin_Flutter_Velocity_For_Complex_Fin_Shapes.pdf" describes how to apply these techniques to fin shapes other than trapezoids or ellipses. Python source code to perform these calculations is in the "src" directory. This code is described in some detail in the companion article. Example input configuration files for all fin examples used in both articles can be found in the "Examples" directory.
