How Do Airplanes Take in Fresh Oxygen?

high altitudes, Because it contains very little oxygen, a human cannot breathe at that high altitude. He loses consciousness and goes on to die.

So how are the planes? We both go to high altitudes and use the oxygen we can breathe in the cabin. can you give it to us? Let’s explain what’s going on in the background while we’re sitting happily on the plane.

Where does fresh oxygen get into planes?

Whether the plane is small or large, whether it is flying low or high; around There is fresh oxygen and they can benefit from this oxygen.

Of course They do not take oxygen and give it directly because the oxygen pressure in that air is too low to be breathed by humans. First it needs to be processed.

So how does this processing process happen?

During flight, air enters the aircraft’s jet engines. This air inside the turbine It passes through the layers of the fan blades and is compressed. In the stage called “compressor”, some of the hot air is discharged through the turbine.

Since the resulting air is very hot, it needs to be cooled in the next stage and passed through a heat exchanger. Now comfortable to breathe, at ideal temperature There is air and passengers can breathe easily.

What happens to “used” air?

Usually at the rear of the cabin, allowing used air to be expelled from the aircraft. an outlet valve that balances the quality of air inside the aircraft It is located.

In short, the jet turbine engines of the plane not only keep the plane in the air, but also allow us to get oxygen in the cabin! Otherwise, we would start to lose consciousness and leading to death We could go on a journey…
