Colin Leighfield Posted December 24, 2016 Share Posted December 24, 2016 I've seen this recently. If you go back to Barnes Wallis' original ideas behind the Swallow project he was thinking the same thing. People think about that as being a pioneering idea in variable wing sweep, but it was far more. There were no control surfaces, the three main components, I.e. central "fuselage" section and wings were moved to alter the aerodynamic profile to the optimum for the intended manoeuvre. For a change of attitude, the wings would sweep forwards or back together. For a banking turn, one wing would sweep forward and the other back and so on. In some ways movable control surfaces are quite crude, changing the shape of the whole "aerodyne" as I think he called it. Daft though it might seem now, the practice of warping wings in the early days was based on the same thinking, but it introduced structural complexity and weight and drag because of all of the external bracing wires etc. With modern materials and control systems these ideas are going to become more practical.

Colin Leighfield Posted December 24, 2016 Share Posted December 24, 2016 It looks as if it was completely unstable in pitch. I can imagine how many letters were in the last word that he ever said. Quote Link to comment Share on other sites More sharing options...
