[NSRCA-discussion] Thick Trailing Edges

[rcmaster199 at aol.com]

Interesting Nat,
 
For a tip chord that is around 10", thats' around 0.15" or around 5/32". 
 
The present tip chord I use in my designs is around 6" therefore the TE thickness would be around 3/32" at the tip of my ailerons and roughly 2X that at the inboard end, which is pretty near what I used. Dumb luck or empirical experience, take your pick
 
thanks, that's good info

I'm mad at myself for not filing the article in KitPlanes so I ordered another copy of the Dec issue. It may be two weeks showing up. I remember Jim Bede, of BD 5 fame, also extolling the virtues of a thick TE.
 
The magic number was somewhere around 1.5% with sharp corners.                 Nat

Hi Guys,
 
Thanks for the input.
 
Now for the million dollar question. What sort of trailing edge thickness are we talking about in order to feel a difference?

The Windtunnel article by Barnaby Wainfain, Dec 06 Kitplanes, discussed controll effects / drag of thick trailing edges. Unfortunately I gave my issue away. I do recall it was all positives for the thicker TEs.           Nat
