Beneath the wings
 

Have a look at the pic first .

What are those things projecting out from the trailing edge under the wing called ??? They are below the flaps .There are 3 of them on each wing for A320 which I think are reducing in size as you move towards the wing tips. The engine is between the first and second one .

Thank you .

Flap track fairings, commonly called "canoes."

Thanks a lot Intruder . Do you know the uses of these ???

They provide protection and aerodynamics to the mechanisms that extend the flaps behind the wings to provide additional lift at take-off and landing.

an elderly couple asked me the same on deboarding. i told 'em. but they insisted those things had to be spare fuel tanks....:D

Slow day :bored:

Thanks a lot for the reply guys :ok:

They are actually the chemical tanks, you know, for the trails!!! :E :}

Oh noes, don't open that can of worms.

Never mind, you just did :}

Convair got them upside-down on the 990!

(No, really, these were known as anti-shock bodies, and did serve as fuel tanks as well)

airbus_adarsh,
You'll find just about every recent jetliner has those "canoes", simply because the wings themselves (towards the trailing edge) are too thin to house the entire 'track AND hinge AND actuator' arrangement that's needed to move the flaps (where each flap can consist of up to three separate elements) up to 40 degrees down.

forget,
I don't think your link was all that helpful for him... what our friend needs is a basic drawing of triple-slotted flaps with tracks, hinges, actuators and all.

barit1,
Kücheman comes to mind. Funny how Convair got it wrong both on the 990 and the 102.

The flap-track fairings date back at least to the Lockheed 14 Super Electra, from which the model 18 Lodestar was developed:
