which gas is used in aeroplane tyres?

Question

and why are they using the particular gas?

Answer 1

Very occasionally for light aircraft air is used, however it is almost exclusively nitrogen that is used. This is for a variety of reasons such as nitrogen does not support combustion and can assist in preventing a wheel fire when the aircraft lands (braking and high speed can produce dangerously high temperatures, especially if multiple sorties are flown). There are other benefits but effectively it is down to being the lowest cost gas that does not support combustion.)

Answer 2

Nitrogen is preferred over air in tyres. A combination of Nitrogen and Helium is also used Upto 1940 and during World War 1, Hydrogen was also used to fill tyres. Later it was banned in 1954 as Hydrogen is a highly combustible gas

Answer 3

Nitrogen gas is used as gas in tyre of aeroplane.It is preferred in comperision with oxygen because nitrogen does not contain water thus when plane is at more hight gas in tyre does not get freeze. when tyre touches land high temperatue is produce & nitrogen does not support fire like oxygen does. thus as it is safe gas. nitrogen is used.

Answer 4

Nitrogen as it will not sustain combustion and will reduce degradation of the liner material, casing plies and wheel due to oxidation. The other reason is it expands lesser than oxygen.

Answer 5

Nitrogen. It's molecular structure keeps it from leaking much. It holds pretty even through temperature differential.

Answer 6

Sometimes just air. Sometimes, dry nitrogen. It's cheap, it doesn't support combustion and because it's dry, the rims do not corrode on the inside.
