water water water ... ( 2 weeks ago by Agui007)
water water water water.....water! Of course they fill the tyres with nitrogen to prevent exploding on ground contact if my memory is still correct.
this is the reason ... ( 2 weeks ago by cirrus2366)
this is the reason airplane tires are fild with co2 and not oxygen so if it catches fire it doesnt explode
They actually use ... ( 2 weeks ago by vwdevotee)
They actually use nitrogen because it is dry, and therefore won't rot the tires from the inside out, but also because it doesn't expand as much with temperature variation.

oh my shit 125 MJ?? ... ( 2 weeks ago by 10mintwo)
oh my shit 125 MJ?? is that right?? on the other video here of a 777 doing an aborted take off they state it dissipated 9.7 million ft-lbs of energy which is only like 13 MJ and that's a whole plane on MANY wheels. why would a single wheel ever have to dissipate 125 MJ?

if you ask for my ... ( 2 weeks ago by halo5549)
if you ask for my opinion it wouldent be that bad beacous you have a bunch of wheels instead of one and you have reverse thrush + speed breaks so it probley wouldent be that bad
Overweight landings ... ( 2 weeks ago by knlprez)
Overweight landings are the same as a rejected takeoff I believe. The test is preformed at the maximum takeoff weight of the aircraft, at the takeoff speed (which is faster than the landing speed), and without the help of the thrust reversers. This simulates a worst case scenario in which there is a failure in the engines and the brakes must stop the aircraft without any help from the reversers. Under normal conditions the reversers account for 50% of the braking power.
To answer your ... ( 2 weeks ago by JRLZAGS03)
To answer your question about aircraft tires keep in mind there is a BIG difference from automotive and aircraft tires. Nitrogen is a dryer, more stable gas that's less prone to changes in pressure due to heat or cold. Nitrogen will not degrade the interior rubber of the tire or corrode the wheels, since it contains no oxygen or water vapor both present in the atmosphere. You should understand all aircraft tires leak nitrogen
Takeoff speed is ... ( 1 week ago by jizzmonger)
Takeoff speed is lower than landing speed.
The more important element is the weight of the aircraft.
That is why airplanes jetison fuel if they have to turn around and land after takeoff.
It's also the reason the pilot takes on a specified amount of fuel at each stop. They want to land the aircraft as light as possible to save wear and tear.
This test simulates a jet fully laden with fuel that has to make a stop on the runway.
Right. The airplane ... ( 1 week ago by jizzmonger)
Right. The airplane tires go from being 50 degrees below zero while the plane is cruising up to about 300-400 degrees when the plane lands.

no fail at all. this is a complete success. the breaks worked till the last moment, plane came to a complete standstill. in the case of an overweight landing being necessary, the pilot has the instruction to keep rolling on the runway until firefighters are arriving at the plane in order to cool down the brakes and avoid a fire.
