| Dale1416 | 17-Dec-15 18:03 | | Fuselage plans show the moveable rudder lines. I should have inked those in on my Albatros model. |
| BriandKilby | 17-Dec-15 18:14 | | thank you dale! |

| Skyediamonds1985 | 29-Dec-15 11:55 | | BriandKilby: This mssg might be a bit too late, but in answer to your question about the rudder, yes, it was partitioned; meaning that it had a vertical fin with a hinged rudder behind it. Looking closely at some of the WW I photos and you can see the rudder actually had a sharp triangular-shaped overhang that extended on top and in front of the fin to act as an aerodynamic balance. It was during the early years of flying when airspeed became faster and faster, that everyone quickly discovered the need for balancing the control surfaces to counter a increasingly dangerous phenomenon called "flutter." This should also explain -in part- the "elephant ears" design of ailerons on many of the biplanes, where there is an extra portion of the aileron sticking out of the wing and slightly forward. Later on, the manufacturers resorted to the use of weights partially hidden in front of the hinge line of the control surfaces instead of using drag-inducing aerodynamic balances. Hopes this helps. -Sky |
