Looks like some type of fluid, any ideas?

Probably just condensation.

It looks to be coming from the fuel dump masts.

Likely the tanks were overtopped and the excess is draining out after rotation.

*EDIT*

On second thought, it looks to be in landing configuration.. So... errr.. I'll concur with condensation.

Ah, that might explain it. I've never seen the masts so far inboard, though. Peculiar.

I think its probably condensation, but what about blown flaps? Do the russians use them at all?

I initially thought it was coming from the fuel dump masts as well. But considering it's landing, that cannot be right...

Just a unique version of condensation in a unique location  Smile

Quoting Airfoilsguy (Reply 6):

Bleed air taken from the engines and "blown" over the underside of the wing and trailing edge flaps, therefore increasing airflow over the flaps and creating more lift. I'm sure someone can elaborate more, as I'm not an expert on exactly how they work.

I think it's the chemtrail dispenser, seems to have suffered a serious leak.

:p

Actually, it's probably just condensation, given the time of year and the location, it sounds about right to me.

Quoting N243NW (Reply 7):

Most of the blown flap mechanisms that I have read about actually blow air across the top of the wing surface and flaps. The Coanda effect causes the air to "stick" to the upper contours of the wing and flap. When the air is blown across a deflected flap, it will be vectored downwards. This makes additional lift.

The C-17 has blown flaps, doesn't it? The original 707 prototype experienced with this too and achieved stall speeds well under 100kts with it!!!

Quoting JetMech (Reply 9):

I might be wrong, but I thought "blown flaps", at least as seen on the C-17, were simply flaps that are extended down behind the engines - into the exhaust stream. They thereby exert a downward force on the jet exhaust, and create more lift.

Corrections welcome  Smile

I agree that it is condensation, but why do you think its landing? The flaps appear to be only about a third to half way extended, which would suggest takeoff.

I was hoping someone else would ask that! Two clues I can think of are the flap position and the attitude but I don't see those as necessarily indicating a landing. But, if it's landing, why are the trails in question extending down and back, even some way behind the aircraft?

My guess is take off. Otherwise the photographer took a pic of it landing then waited for everyone to deplane, fuel up, new passenger boarding, and push back in order take a pic of push back.

As one can see when looking at the left FTF (seen from behind the aircraft), that stuff is coming from the upper side of the wing, not out of the FTF. So I don't think it's fuel.

Both methods are possible.
Exceptions confirm the rule.

Those two pictures, though taken of the same airplane at the same airport on the same day, were not taken by the same person. So, chances are one person took a picture of it it's arrival, and then the other took a picture of it about an hour later pushing back for departure..

Yes, you are correct. Improper use of the search function on my part.  ashamed

Definately taking off, check the flap position on a landing IL96:

I've always loved the Coaler. I don't know why, but there is something really aesthetically pleasing about it to me.

Quoting A342:

Agreed.

One is internally blown flaps, where the bleed air is channelled through the wing and then vented out the back. I have a feeling that this was really only common on fighters, with a centrally-mounted engine like the F-104.

The other is externally blown flaps, which Vik was describing. Interestingly, the A380 uses this concept.

By the way - check out the stall speed on this thing;

Anyone aware that these type Flaps exist on the IL96.

Yeah, that, and I've been taking a liking to the Tu-154. Don't ask why, but those are the only two Russian commercial jets that I really like.
