Are they washing the props? or cooling the engines? or what????

Can any Russian airplane buff shed some light ?

New ramp agent doing a prop wash?  

Seriously though, I was wondering the same thing when I saw the picture. There is no explanation in the remarks.

If they water it, maybe it will grow to become an An-124...

He's the new guy. After he gives up looking for prop wash they send him to fetch some flight line.

The photo caught my eye, on the home page of A-net. I thought it was just stander practise.

The location is within a couple miles of the Sea of Okhotsk...I'm not sure what route it came from or what altitude AN24s usually fly, but could it have to do with salt from the sea collecting on the airframe and removing it to prevent corrosion? I know the Navy has showers for some of their low-flying aircraft, so it might be a similar principle. Just a thought, I'm curious too...hopefully someone who knows for sure can chime in with the right answer.

I've read before that the Antonov turboprops were notoriously hard to start on hot days, and a common solution was to spray cold water at the inlet to cool the engine. I'm not sure how true this is, but it almost makes sense - you can get an extra boost of power from the ingested water, almost like water injection on the early turbojets.

This photo shows a similar situation, with a brief description.

Dunno, but from a safety point of view, and as a former line worker, I can say that standing that close to a turning prop is definitely not very safe   Even with the engines at idle, those props are still producing lots of thrust, and you could get picked up by the airflow...

Judging by the trajectory of the water, the props are at zero pitch and producing zero thrust.

No idea what he is actually doing though............

Must be the newbie on the ramp. Now, the poor guy has to collect enough of the water that dripped onto the ground to fill a bucket so he can take it back to his supervisor, who asked him for a bucket of propwash

A crude form of water injection.

Could it be a crude compressor wash , as I seem to remember other turbo props used to require compressor washes

I guess Hes using the rotation of the blades to generate a higher impact by the water on it.But I still feel a stationary clean up would have been easier & faster.

It could be that the engines are running not to improve the cleaning, but simply because the hose is not located in the area they wish to park. Perhaps the flight crew simply taxied over for a quick wash on the way to their parking position.

Or some kind of dare? I'm not sure just what it take to get me to stand in front of a plane like that with both windmills turning and no chocks in sight, but it would be a lot.

There is plenty enough clearance under An-24 family props, what would bother me though are the gear legs... not fun being driven over by one I suppose.

Further up and to the side. The outlet on the back of the right engine is actually for a turbojet booster engine found in the right nacelle, not for the turboprop.

I have not seen it elsewhere than in An-24 family. The booster engine doubles as an APU.

Although, for some reason, I cant stop thinking of Trident.
