Clark Ross Posted September 4, 2009 Share Posted September 4, 2009 the reflexed airfoil on a plank type wing has no washout. the reflex is there to stabilise. and the twist is there on a swept wing for the same reason and washout is just a secondary benefit . wihout the twist the wing would tuck under. the me163 is a good example , you can see the twist in the wing the question is how much do you need to counteract the lift forces that cause it to tuck under regards clark Quote Link to comment Share on other sites More sharing options...
Erfolg Posted September 4, 2009 Share Posted September 4, 2009 I seem to be missing something? Where did this twist and tuck under come from? As for washout being necessary to prevent tuck under, I would query that! I have flown a number of wings (well two, may be five), without washout, never had tuck under. I always thought that the wash out was for the avoidance of tip stalling, with sweep back? Never use it personally, that is because my sweep back is moderate, or if a plank, there is none! Must be asleep again! wher is this wahout coming from? Erfolg Quote Link to comment Share on other sites More sharing options...
