This release allows the user to analyze a fin for fin flutter effects. The current implementation has some limitations but is useful enough that it is worth releasing as is.

Features:

  • Fin flutter is calculated using the method outlined in NACA Technical Note 4197
  • Atmospheric model is coesa76, an extension of the US Standard Atmospheric model that works above 84 km altitude
  • Material editor allowing you to create your own material presets

Current limitations:

  • Trapezoidal fins only supported at this time. Elliptical and custom fin shapes are not
  • The software assumes uniform thickness. Tapers, airfoils, etc are ignored.
  • Material information is not saved with the fin. It will need to be reloaded each time
