[NSRCA-discussion] Trailing Edge

The old NACA must have done this research in the distant past. I recall, in the 80s, Jim Bede extolling on the virtues. 

 The Princeton project, that would be fun, especially as a student. Would have kept my attention <G>.              Nat

  Thanks Nat,
  I have a guy in the local club who corroborates Barnaby's statement. Locally to NSRCA D1, back in the 80's he was known as "forever in Sportsman George".
  He is recently retired from teaching at the Aero group at Princeton U. and he still coaches the students involved in the weight lifting contest.
  It was nice to have an excuse to go hunt him down!

  later,
  Dean

    Kitplanes, Dec 06           Wind Tunnel by Barnaby Wainfan

    " The airfoil with the chopped trailing edge will produce slightly more lift at the same angle of attack than a sharp trailing-edged airfoil. Because the wake is filled in the controll is crisper and more effective and does not have to move as far to cause a change in lift"
