Missing Part On Vueling A320 Wing

Mon Jul 28, 2008 6:43 pm

I just flew on Vueling's EC-JGM and spotted this:



How's the missing part called in technical terminology?


Thanks

Flap Hinge Fairing... they can be CDL, but I'm sure they take a speed or fuel hit.

We call them flap track fairings, or because we're in Canada, they're more often called canoes.
The primary function of the design engineer is to make things difficult for the manufacturer and impossible for the AME.

They're fairly often called "canoe fairings" in the US too.

Just to add that it is "just" a fairing and as such has no structural function. It decreases drag and keeps quite a bit of dirt out of the mechanism.

Flap canoe. As said it is basically just a fairing to help streamline the flap mechanism, as well as protect it from dirt etc.

Edit: If you want a true technical answer, I'm not sure what Airbus uses for terminology but in the B737-100/200 maintenance manual the official name is "flap track fairing".

Out here...Reffered to as the Flap track fairing,used to cover the Screwjack area of the TE flap track to reduce drag in flight,can be deffered under CDL.

How is the TE transmission on a A320.My post was with experience on a B737.

I answer because I thought I could add some info.If people were to worry about grammatical errors & punctuation marks & not contribute even a small percentage of data,there would never be a forum or discussion.I don't state I'm the Know all around here.I too like many visit this forum to learn lots & share little & We know where we stand practically.
The purpose is to educate oneself.

True....because of a habit...I do forget to use the ? mark often,but I don't think its a crime on this forum.Whats important is the message going accross.

However I agree to what you say that the operating mechanism may be different unlike the B737 whose Flap track fairing covers the Screwjack.On the A320 Is it called by another term other than Flap track fairing/Flap canoe?
But its def for Aerodynamic purpose too.

Cheers.

According to the Configuration Deviation List (CDL), they are two parts, combined they are called "Flap track fairing rear top cover and tail cone"

Quoting EMBQA (Reply 1):

None, zip, zilch, zero

If the whole flap track faring was missing, fuel consumption should be increased by 3%, and TOW reduced by 1%.

Mel,

When I first went into product support, we corresponded with the customers by SITA or TELEX and the only punctuation they used was the . (period). Later we started using fax and it was real hard for me to break the old habit.

Additionally I took a technical writing class and we were forbidden to use the ? mark. No questions were allowed, neverything had to be written as a statement.

So while we're talking flaps, does anyone have similar (like the one iFixPlanes posted) diagrams, or is willing to write a description, of how flap actuating mechanisms work on other airliners?

Thanks.presume the torque shaft is transmitting motion to the adjacent flaps.

Mine was a bet I had on the forum for 4 yrs of not posting a ? mark.I won the bet but need to break the habit.  Smile

On most Boeing's, you have a motor(s) in the wheel well that turn a torque tube that runs along the trailing edge. There is a gearbox at each flap fairing that picks up the torque tube and spins a jackscrew that sits inside the fairing. The flaps are mounted on carriages with a big nut that goes over the jackscrew. When the jackscrew spins, the nut moves along and takes the flap carriage with it. The carriage has rollers that ride in big rails (flap tracks) bolted to the rear spar. The profile of the flap tracks controls the flap motion. I hope that makes sense.

Makes perfect sense. Sounds a lot like a power seat in a car, minus the torque tube and the hydraulic (I'm assuming) motor.  Wink

Thanks!
