Question About ERJ Wing

[User546]

http://www.airliners.net/open.file?id=806926&size=L

We parked next to an ERJ at Customs in Mexico earlier this week, and I noticed something I couldn't figure out.

Maybe I have never paid close attention before, but on the leading outboard edges of the wing, there were four yellow fins facing forward.

What is the purpose of these, and are they on all ERJ's?

Thanks in advance.

They are called Vortilons...helps wing stalling characteristics

I'm sorry, but those are head whackers. The sole purpose is to scar you about the face.

Actually I do find on my early morning pre-flights, that the Vortilons do a much better job of waking me up than my mocha-java-chino-caf-half-tai-chi-skim-foamy hot beverage.
Those can poke an eye out ya know!

From what I underdstand they pretty much allow the airplane to get by without Leading Edge high-lift devices, saving a lot of weight.

Basically, they're low-weight alternatives to slats; at high angles of attack, they direct airflow over the ailerons to ensure effectiveness.

Any of you ever see the pictures of the NetJets guy that got a static wick in the eye while doing his walk around?

Not very pretty.

Is that what happened to your avatar??

Thanks for all the great information. Never heard of a Vortilon before today!

Yea, just happened to run across those pics on my computer a few days ago.

Still makes me cringe to this day when I see those pics, and while checking the static wicks during the preflight!

The guy who that happened to was a member on here at one point if I remember correctly.

True about the aileron effectiveness in that they prevent span-wise flow of air. They also double as a vent for the bleed air that heats the wings. I am not sure about the leading edge lift device though.

now if Colgan can do the same, they will too have a inflight training device.

Don't forget the FTD!

They don't "vent" they are heated so you don't get ice on them.

Vortilons get pushed into the airstream ahead of the leading edge. Once their, they act just like vortex generators.

[EMBPLT]

Yes they are heated as well, and the "VENTS" on the back of them vent the bleed air out of the wing. That is why it is a preflight item to be checked for anything that may have blocked them. I learned this from an instructor at FSI who definitely knows more about the E145 than anybody out there.

Another thing - Not that I don't agree with the fact that they act like vortex generators, however they naturally sit out in front of the leading edge in the airstream. They don't get "pushed" anywhere. They are a fixed object. Do you mean their or there?

As you know, I'm sure, there are already vents for the wing, three of them. The vortilons are heated for ice protection and the slot is to exhaust the used hot air. They are not additional hot air exhausts vents as you imply. The pre-flight check is to ensure the vents are clear so the anti-ice for the vortilon will function correctly. As an aerodynamic device they must be kept free of ice. This information is from the factory in Brazil when i paid them a visit a while ago.
This has to be a joke. My experiance with Flight Safety does not back this statement up. Poorly trained and lacking in basic knowledge is what I have experianced there.

I bet you are talking about Clem. He likes to tell people that he knows more about the E-145 than everyone else. I was in his first class when he was a ground school instructor. It wasn't pretty. The guy was clueless.

 

[bayoubandit]

I dunno DK. I remember sitting in ATR school with Clem and his stick pointer over his shoulder talking about the DC BTC PB like there was no tomorrow.

Didn't have much else to do but listen since Elaine had already eaten all the donuts.

Yeah, those FSI guys can tell you about all the nuts and bolts, and how many rivets are in the airplane, but they probably couldn't fly their way out of a wet paper sack.

They're like feds... they can play airplane trivia but can do little else but to bust the cojones of the guys who fly.

 

[bayoubandit]

No kidding.
Remember the guy who put a hole in the wall with the sim at FSI. Must have been some pretty aggressive flying.

I never had Clem for the ATR. My instructor was much more cute!

Clem had something like 15 years teaching the ATR. I think that eyes closed thing with the poster was nothing more than a neat little Parlor trick. He only did it to inflate his already over-inflated ego. I am sure that he practiced a few months at home before he tried it on his students.

I was always amazed how people thought he was the smartest guy in the world when it came to the ATR. I would always repsond. "Well he has been teaching systems on this thing since it was made. If he didn't know every nut and bolt on the airplane then there would be a problem."

I found him to be a sub-par instructor and a condescending douche.

Hey DK,

I'll have to give you a call and catch up.

Bet you didn't call 'em that in your type Oral with Senior!

A buddy of mine did for his type in the airplane. Let's say the Major was not impressed.

Has the Major ever been impressed by anyone other than himself?
