Notes

  • Elevons combine elevator and aileron: both move together for pitch and opposite for roll, which is how tailless wings and deltas are controlled.
  • Concorde used only six elevons, replacing elevators and ailerons, with no flaps or slats, where subsonic wings may have more than 50 movable devices (Heritage Concorde).
  • McCombs notes free-flight scale models can trim glide turns with elevons (Model Aviation).
  • Used on: Concorde.
  • The file is a reference example built by Xem Studio from the numbers above. Sizes the sources do not fix are illustrative; scale the example to your own vehicle.

Questions

Why do flying wings use elevons?

With no tail, the wing's trailing-edge surfaces must do both pitch and roll (Heritage Concorde).
