Water Corrosion On The Beriev Be-200

Wed Sep 10, 2008 12:48 pm

The Beriev Be-200 has got to be one of the most unique aircraft flying today. However, when I see pictures like these I often wonder whether water corrosion is a major concern. It seems to me that it sits really low in the water. Also, that's a lot of water that's going through the engines on a regular basis.

There are a few examples of turbo-prop flying boats in the West, like the Canadair CL-415- where the engines are safely above any water spray.

Would you ever see this sort of aircraft doing salt-water operations?

Would that be the reason why we don't see this sort of jet aircraft designed an built in the West?

Could it be used for civilian / passenger use?

Gelendzhik is on the Black Sea that is salty, though only half as salty as the oceans.

That's not on a regular basis. As described in the photo caption, it was due to high waves. Normally, the engines aren't affected by water spray.
Exceptions confirm the rule.

I don't see any high waves in the picture. I saw that and wondered why the photographer said there were high waves?

He didn't say there were high waves. He said there was one. Maybe a single accidental flush?

I am not a tech expert, but can throw in an assumption that there won't be that many special provision for or concern regarding corrosion on the Be-200. Regular planes are subject to just as much moisture in the sky and on the ground in the areas where it gets drenchy.

As for the water getting into the jet engine... there was a topic recently on this forum about engine noise changing when passing through a cloud. There were posts explaining how sound changes due to water etc, but also that jet engines actually benefit thrust wise, if anything, from some water injestion.

I know of at least one aircraft which I can't mention which 'burped' during water ingestion cert testing... too much water has an adverse effect, just a little can help cool the air which makes it denser which gives you higher pressure which gives you more thrust!

Lot of Titanium in the Be-200, which don´t corrode in saltwater. Remember that Beriev got
long experience with this kind of aircrafts, since the Be-10 that flew first in 1956 and the Be-42 as well.

Today in the news saw footage of Be-200 at a HydroAirShow 2008 and they revealed a measure against corrosion - sprinkling the plane with fresh water at the airport to wash out any salt water it came in contact with.
