Saftey of exposed wheel at 41,000 feet

I think he's asking about either excess tire pressure bursting the
tire or the tire expanding and getting stuck in the wheel well.


If that's his concern leaving the wheel exposed would make no difference as
wheel wells are not pressurized anyway.

Sorry, but the tires on a Citation are inflated to 120 +/- PSI on the nose
wheel and 98 PSI on the mains. They are filled with dry nitrogen.


Not maximum pressure, maximum pressure differential. Normal sea level
pressure is about 14.7 psi.

Your math doesn't add up (how cliche' )


How so?

B-737 don't have main gear doors either. But I don't know if a 737 can
cruise at FL410.

Hello,

How safe is Eclipse Aviaion's decision to expose the wheel on jet that
cruises at 41,000 feet?

Has this been done before? On what airplane?

Cessna Citation's have half open wheel bays. They cruise FL410 and up.

differential is about 15 psi, which is trivial for a tire.

Apparently, another "sorry" would be in order. What he's saying is that
the
difference between sea level and outer space is only around 15psi, which
is
PROBABLY an almost insignificant fraction of the pressure usually existing
inside a properly inflated tire.

I suppose that he could be saying THAT! I figured he was addressing the
outside/inside air pressure.

Safe from what?

If the aircraft isn't supersonic and the wheel wells aren't
heated and pressurized, they are going to see the same environment
whether they are hanging in the breeze or totally enclosed.

Nowhere does the original poster make any inferences to anything. It is
a straight question.

Which means that, if you took one into outer space, the nose tire would be
essentially at 135 PSI and the mains at 113.

Still the 'ol PITA, eh George?
