1.
Pure nitrogen is dry and does not absorb moisture. This helps with corrosion, but the main reason was that with air filled tyres and moisture collect at the bottom, froze in flight and created an imbalance when landing.
You started
so well, but......whilst we are never too old to learn, and despite my lifetime involvement as an engineer, I have never heard, or read, anything about wheels becoming inbalanced due to, erm, frozen water in the wheel hub.... 9/10 for creative thinking....1/10 for factual content. Do you, by any chance, have any documented evidence concerning aircraft wheel and tyre assemblies to support this please ?....because, having perused some excellent material from Mr Goodrich / Dunlop
et al, I cannot find, or recall, any reference to this phenomenon.
2. N2 molecules are larger than than O2, and so pressure loss is slower.
Oh ?
3. Its inert and wont contribute to a fire
At last ! success !.....
