  • Airfoils - or as we Blimy Brits call them Aerofoils. Konrad having gone so deep into this on the Gremlin thread, - as he always seems to - as its a vast and sometimes pretty interesting subject, I feel the need to explain a bit about these aerofoils here in a new thread.
  • undercambered section, that number is perhaps 95%. The main reason for a curve on the top surface of the wing is to control drag at the very high angle of attack that is required to fly slow and rack up glide time. Your wing produces lift by displacing air downward, equal to the weight of the glider.

  • Nov 05, 2016 · On a conventional aircraft undercambered wings have the best slow speed performance but are not too good for speed. Flat bottom profiles are almost as good for lift with a slightly better speed range, semi-symmetrical profiles are better at speed again but lose lift as a result and finally symmetrical wings give the best aerodynamic performance by lose some lifting ability as a result.
  • To choose this airfoil for C/L stunt, is an absolute, elementary mistake. This so-called "laminar" airfoil is designed for fullscale sailplanes' vertical stabilizers, for Re at least 1.000.000, for minimum drag and high efficiency. (We used to fly sometimes no more than 350.000, pretty below the critical Re value of FX-150)

Sep 17, 2010 · Are you refering to a different report that said undercambered wings are less efficient than thicker airfoils, even at low speed? Many sail planes try to have have undercambered wings, but compromise with an undercamber in the back. Maybe sailplane technology has changed since that was written though.
Jul 18, 2003 · Hi! Im looking for the following airfoils: Wortmann FX S02 196 (inner wing) Wortmann FX 60 -126 (wing tip) do you have them? I found a lot of infos about them but Im not good at using airfoils maker and I cannot create them for XPlane ??? thanks in advance for your help! luca
