Winglet?

Couldn't find any aileron modifications on google... :confused:

Thanks for looking. There is a cessna mx shop right next door to the aircraft and I will mosey on in and ask. I wish I could upload a picture, but I lost my phone/usb memory to transfer pics from my phone to the computer.

If you look at the STOL kit, it ends at the leading edge of the aileron,while the thing I saw ran from the trailing edge of the aileron to its leading edge.

The reason "winglet" came to mind is because when the aileron drops, there is a new "outer wing edge" between the flap area and the aileron area. My initial thought was, "why would you want to prevent low pressure to high pressure flow in that specific area between the (retracted) flaps and aileron--i.e. like a winglet does at the outer edge of the wing.

Again, thanks for looking.

I lost my phone/usb storage doo-hickey and can't upload to a computer. too broke to buy a new one.

Sorry, I really wish I had one. I will defintely ask around, the a.c. is parked next to a cessna mx shop and I will poke my head in and ask.

Where else but in pilot-ville can you have a discussion about a skinny strip of metal on top of a wing and enjoy it..

Gotta love it.

Thanks for your help.

Thanks, interesting stuff. I read up on it a bit and posted a video of "The Sabre Dance" http://forums.jetcareers.com/1278521-post1.html


This morning, I started putting the elements of a lesson plan together for the Aileron Fence, but looking closer at TGrayson's document http://www.pacificaerosport.com/docs/Symphony%20Description.pdf (Thanks, TGrayson, again) I noticed that the Aileron Fence is in fact attached to the aileron. Now, it was dark last night when I walked by, and it seemed like the "fence" was attached to teh wing, not to the aileron. So, I put aside my lesson plan until I can verify it.

Matter of fact, I will walk up to the airport now and take a look, back in an hour or so.

Edit: just got back from korl, of course the aircraft is out flying (its a beautiful day here). However this is a Stationaire parked nearby that does have them. I will walk up tomorrow and take another look.

A related question, is what to term to classify these things under. Let me illustrate via a negative.

They are not leading edge devices
They are not spoilers
They are not airfoils.......


ideas?

These are often referred to as "aerodynamic fixes," since they are typically added when flight testing shows problems with aircraft behavior.

Thank you!

I smell a lesson plan starting to take shape:

Here's my beginning outline...

Subsection Fences:

Wing Fences:

What:
Why:
Aerodynamics of:
Further reading:
​
Aileron Fences:
​
What:
Why:
Aerodynamics of.
Further Reading:
​
Other Fences?
​
Subsection Other Aerodynamic Fixes?

What's funny, is I was just walking past an airplane, saw a funny piece of metal stuck to it I never saw before, asked a few questions and now I have this entire subject to mess around with. Everybody should have this much fun.


Thanks again for the tip.

Are modern aircraft now moving away from winglets for raked wingtips? Aren't those more efficient?

I've always heard of these "wing fences" referred to as "stall fences." The Beech 1900 has them as do many other aircraft.
