What are the dangers of volcanic ash clouds to aircraft?

Internal combustion engines work by drawing in air, which in turn produces energy. Volcanic ash is capable of burrowing into the parts of aircraft engines, causing all sorts of damage. Just like driving a car in a sandstorm, the internal parts of the engine will get clogged.

In addition, tiny particles in volcanic ash can clog the pitot tube, the airspeed sensor. Dust can clog these devices, which can produce false readings. As a result, the aircraft stalls and the pilot may not know the speed at that time.

Ask for a satisfactory answer.

It affects visibility, it is not good for the engine, it has an impact on some other equipment. In short, it endangers flight safety.

It has volcanic ash activity, that is, it can react with lime (CAO) at room temperature and in the presence of water to form hydrate with hydraulic gelling ability, which is equivalent to covering the fuselage with a layer of cement.

There's a threat, otherwise when the eruption happens, the planes won't be grounded.

Instruments fail, volcanic ash can crash planes.

1. Cause engine damage or even stop. The engine is composed of a fan, a compressor, a combustion chamber, a high-pressure turbine, a low-pressure turbine, and a nozzle, and a large amount of volcanic ash will cause the cooling holes of the compressor and turbine blades to be blocked, and the engine efficiency will be greatly reduced.

2. The airplane's cabin pressurization and oxygen all come from the engine's bleed air, and if the bleed air contains volcanic ash, it will be introduced into the air-conditioning system of the aircraft's cabin, endangering the lives of passengers.

Therefore, the airspace with volcanic ash must not be entered.

In fact, it is very simple to be high-profile and low-key, and it is not as much as you say. To say something nasty (don't be weird, haha): You don't need to read that big paragraph above!

Going around! I'm wondering, did you come up with a lot of the above paragraph yourself or did you turn it around? If you're trying to figure it out, then you don't have to go up here and ask questions about it.

If you turned it, then I ask: do you understand? If you understood it completely, you wouldn't be here to ask such a question.

In fact, being a person, whether low-key or high-profile, has its advantages. You ask, "If you want to be a low-key person and do things in a high-profile way, can you coordinate and unify it in one person?" Isn't there a conflict between them?

High-profile work is actually simple, but not everyone can be low-key, and the basis for being low-key is that it can be high-profile at any time. Do you want to keep a low profile? Do you want to do things in a high profile?

Don't you know the truth that "things are done by people"? You don't raise your profile, so how can your affairs be high-profile?

In short, in this society, it depends on your ability to act. If you have the ability to be high-profile, be high-profile! If you don't have the ability to be high-profile, if you bite the bullet and go high-profile, you will be lifting a stone and shooting yourself in the foot.

It's good to be a low-key person. We also have to be low-key, low-key, low-key, and even low-key many times like street sweepers and 、、、 people. Maybe in the eyes of others, we are not as good as others!

Responsibility is the first requirement to do a good job;

Constantly pursue a professional work style and constantly strengthen the professional work quality;

It will affect shipping and may cause passengers to be stranded.

How volcanic ash affects aircraft.

The volcanic ash contains silica, a compound with a melting point of 1,100 degrees Celsius, compared to 1,400 degrees Celsius in the turbine engines used in most airliners today. Once the ash is sucked into the engine, the silica melts and adsorbs onto the vortex wheel blades and turbine guide blades, causing the engine to stop.

As the plane continues to fall, the silica gradually cools, solidifies, and accumulates, peeling off, and the engine is restarted.
