Smoke generator to assist in the wake vortex testing I would guess.

Where's the fuel dump exhast on the A380?

I would imagine the wingtips. I would hope it would not be right behind the engine...  covereyes

i also noticed during airshows that the reverse thrust doors on the engines of the A380 are only open on #2 and #3, is that just during the show or is it that the airplane is designed to do that?

Correct. They injected fluid into the engine exhaust to make the smoke so the wake vortex would be visible.

you are right, there are only TR on engines 2 and 3.

The smoke looks like it is very high on the engine, not in the tail pipe. It could be a smoke generator attached to the engine strut, as the rudder doesn't look deflected, which it would be with an engine shut down.

The A-380 would have gone through several engine failure tests, in flight, and on take-off continued. For 4 engine airplanes, failing the outboards usually tells you a lot of how the airplane will handle, but they also do failures of the inboards.

The A380 only has T/Rs on the Inboard Powerplants.

It's been discussed before, in other threads...but the reason behind this is that on most regular, and all small, runways, the #1 and #4 engines will actually be over the grass areas on the sides, and it's not the best idea to run a reverser over grass and all that.

Apart from Extending outside the Runway Area, & the FOD during reverse Thrust.Braking is primarily still adequate.

Anyone aware of the details on the Test on hand in the Pic.

I'd say the main reason for not having outboard reversers on th A-380 was weight.

Ballpark, I would expect 1000-2000 lbs per half.

ie approx 500-1000Kgs addition per side.Max 2000kgs on the Aircraft.Would that trouble A380.

Interesting.So Simon [Jetmech] was right after all.

Was just thinking what about Interiors could not that have contributed some more savings in weight & left the T/R s on.

Every little counts. 1-2 tons is nothing to sneer at even on an aircraft that size. The same weight in payload or fuel makes quite a difference.

I'm sure the interiors on Airbus's can lose more weight! I remember pulling out the switch that was used to turn on the light located on the main door of an A330. The switch is just the tip of the iceberg. Behind the switch is a module that is about the size of a brick, which probably weighed a good two or three kilos! All that size and mass just to turn on one light!

2000 kg will cost an A380 about 100 nm of range (1.2% penalty)
