Ordinarily, I would just let this slide; but since the greenies have
decided that CO2 (which is nature's means of recycling oxygen) and O3
(which is nature's cleanser of the atmosphere) are "pollutants"
according to the strange reasoning of their adled brains, I feel
compelled to point out that I suggested that the aircraft would be
sheltered in a hangar--which would protect the outsides of the tires
from part of the damage. They still won't last until the treads wear
out, but it will help.
You're suggesting hangars are so airtight that CO2 and O3 are somehow
sealed away from the tires inside? The effect of O3 on tires is not
through increased UV or global warming. It's direct chemical interaction
with the polymer chains in the rubber compounds.
Not at all. However, UV is supposedly a player in rubber deterioration.
Via a separate mechanism. That's why tires are made and/or treated with
ozone protection additives.

There is not much you can do about O3, you'll just have to live with it.
Bull****. Reduce the amount of hydrocarbon and nitrogen oxides emitted by
various sources and you reduce the amount of low-level ozone produced by
their interactions. I'm not talking about the ozone layer here. I mean the
air we're breathing at our level of the atmosphere.

...and YOU are going to accomplish all of that for the good of your tires in
YOUR hangar...

WOW! I'm VERY impressed.

Whoosh...

Learjets do indeed use bottled oxygen and it is found in the nose bay
area. There is a thin capillary that runs into the cockpit to a pressure
gauge. The pressure gauge displays the pressure in the tank regardless of
whether the valve is turned on or off. The pressure in the tank can read
full on the ground but at low temperature at altitude will read several
hundred pounds less.

They do? For primary breathing air at altitude? Is there no cabin air
pressurization provided by bleed air from the engines?

I'm not doubting your word, just trying to understand. I thought all
bizjets used bleed air to pressurize the cabins.

I am sorry Jim, the O2 is for emergency use. The cabin is pressurized from
engine bleed air. The O2 masks drop from the ceiling at 14K' cabin altitude
just like the airliners.

The thread on brakes raised a question from the past- why nitrogen
in the tires of big jets and heavies? Air is around 78% nitrogen
anyway, and the coefficient of expansion of the remaining 20% that's
oxygen can't make that much difference in volume.

Why not just use dry air? I couldn't imagine that dry air or dry
nitrogen could make that much difference in corrosion, either.

I seem to recall someone giving me the rationale for this a long
time ago, but also seem to remember thinking it didn't make that
much sense at the time.




Well, the greasemonkies say it preserves the rubber. Having said that
we go
through them pretty quick and even considering retreads there
wouldn't be years of exposure or anything..
Wheel fires may be another good reason...

Right, they are called Napoleon tires. You heard of "Napoleon Blown
Apart" haven't you. :-)


groan!


A guy i used to work with witnessed the aftermath of someone trying to
fill a 707 nosewheel wiht an incorrect type reduction on the bottle. The
guy was pretty much vaporised. My friend spent months as a witness in
the subsequent lawsuit.

You're a cross posting dumb ass.
