  4. BoKu liked wsimpso1's post in the thread Wing design for lightest possible wing.

    The lightest possible wing? A search of the design space is how this sort of thing is usually done, but we can shortcut the process...

  7. BoKu liked Marc Zeitlin's post in the thread Raptor Composite Aircraft.

  9. BoKu liked Scheny's post in the thread Raptor Composite Aircraft.

  10. BoKu liked pictsidhe's post in the thread Raptor Composite Aircraft.
