We all know that the car tires around us are filled with air, so are the airplane tires filled with air?
But since flying at high altitudes causes the tire pressure to rise, wouldn’t filling the air make it easier to blow out a tire?
Let’s take a look.
In fact, airplane tires are very different from automobile tires. Automobile tires can only detect tire pressure at most, while airplane tires can not only detect tire pressure, but also inflate and deflate by themselves.
It does sound like a very dark technology, but it does suddenly solve the problem of having less air in the air to combat the low atmospheric pressure;
When it hits the ground, it needs a tire drum to combat the high atmospheric pressure.
And the plane will adjust how much gas it’s charging, depending on its weight and how fast it’s flying.
In addition to self-inflating and deflating, airplane tires are also different in that they are filled with nitrogen instead of air.
Why is that?
The original nitrogen is a kind of inert diatomic gas, chemical characteristics are not lively, the speed of thermal expansion and cold contraction is slow, the volume is not easy to change.
Nitrogen is added to aircraft tyres, which do not have a large effect on their volume due to violent changes in pressure.
Another advantage of nitrogen is its low audio conductivity, which is equivalent to 1/5 of ordinary media. Nitrogen charging of aircraft tires can well reduce the noise of tires and improve the calm and comfort of driving.
In fact, the tires of not only airplanes but also racing cars are mostly filled with nitrogen.
