I find this hard to swallow, and I doubt that oxygen (at 20% of air),
regardless of pressure, is going to cause a detonation in an oleo.

Our oleos are a little more, eh, enthusiastic shall we say, than the
oleo on a cherokee! Thumping a hypothetical airplane that weighs, say
500,000 lbs onto an oleo strut of about a foot in dia at, maybe over
1,000 fpm rate of descent is going to get things pretty exciting inside
the strut.I have no idea what the compression ratio is in there, but
it's got to be reasonably high.
I do come across one grease monkey who has answers galore. Anything he
doesn't know he finds out for me the next time I'm through. He's just
one of these guys with an insatiable curiosity about all things
mechanical..

Just like in a tire, the percentage of oxygen remains the same, so its
ability to support combustion also remains the same.


Now, the
increased oxygen pressure might slightly increase the risk of
corrosion, but we are not talking orders of magnitude higher compared
to ambient. At least this is my understanding as I recall from being a
chemistry undergrad and grad student.

Apparenlty, the increased prsssure makes O2 much more aggresive so the
effect is not slight, but in any case, I'm only telling you what my bud
said and he's quality control for a big airline.

The more I hear about this, the more I think it's an old wive's tale.

Anway, what did you think of Anthony's claim"it's not me?" What a
moron.

Oh yeh. Couldn't care less if it's him or not, to be honest!
