Winglet?

Walking home by KORL, I passed behind a single engine cessna with something I have never seen before.

Think stall strip, but with these properties.

Its about 2 inches high on the trailing edge of the wing running fore to aft.
Inboard of the aileron and as long as the aileron is fore to aft.
Outboard of the flaps. I.e. between the flaps and the aileron.

I have never seen this and the thought occurred to me that it acted as a "winglet" whenever the aileron dropped relative to the trailing edge of the wing, it would be there to prevent leakage from below the wing to above.

I don't have a clue, though.

I tried to google it using "winglet" and "airfoil", but no luck.

Anybody?

thanks

Edit: Maybe its a wing fence. http://en.wikipedia.org/wiki/Wing_fence
Edit: Edit: naw, that makes no sense, its not a swept wing a.c.
 
Could be a STOL kit. One of our 172's, actually cessna's poster child has it. Tlewis95 has a pic somewhere. It's N 172SS

It's a device to increase the lateral stability of the aircraft, boosting the dihedral effect. When encountering a sideslip, it causes the aileron to deflect in such a manner as to raise the wing, eliminating the sideslip.

Almost...

Shorten that thing to the lenght of the aileron--fore to aft.
Scooch it back so its tail end is at the trailing end of the aileron.
With the flaps retracted, the aft edge of the thing sits between the aileron and the flap, its length is only as long as the lenght (fore to aft) of the aileron.

Then that's it.

Cordially,

Edit: what the heck is a STOL kit?

OMG, :confused:

These are winglets on the end of each wing.

In the other picture is a STOL kit.


:insane: to OP.

this is almost a riddle

Edit: STOL is short takeoff and landing... STOL kits are generally an addon or modification to an aircraft to improve takeoff and landing performance.

Thanks for the info on STOL, I have never heard of it before.

As for the riddle, it looks "exactly" like the picture, except it does not run the length of the wing. It only runs from the trailing edge to the leading edge of the aileron.

Cordially,

Thanks, but I know that. The thing about google is it gives related search terms, that eventually lead you to an answer. Searching for "winglet" let me to wikipedia, scroll down about halfway and you see "wingtip fence" which looks a lot like what I saw.

Thanks, you have given me something interesting to think about. This is fun.

you need special training to fly airplanes with winglets. go talk to your instructor about a "winglet endorsement"

the mighty 172M. M stands for marvelous.

best airplane that ever flew.
