Airplanes can fly high in the sky, but why can t they fly up Mount Everest?

Some temperatures and climates are not suitable for the flight of the aircraft, and the flight danger factor is very high, so avoid the aircraft flying on Mount Everest.

Because the environment above Mount Everest is very harsh, the plane cannot work properly when it flies to it, so the plane cannot fly up Mount Everest.

The aircraft can cruise at high altitude, if it lands and needs low speed, then it is necessary to put the flaps to improve the lift, but when the aircraft is at low speed, at the height of Mount Everest, affected by the type of the aircraft, it is impossible to operate the flaps. This results in the aircraft not being able to slow down. Unable to land.

Airplanes can fly up Mount Everest. The flight altitude of the current civil aviation routes is 8000 to 10000 meters, flying over Mount Everest is not a problem, Mount Everest is only more than 8000 meters, military aircraft is not a problem, if you use ***, the climate is bad is not to reach, if you can find a landing site, the plane can land on Mount Everest, otherwise you can only fly to and can not land.

Information on Mount EverestThe height of Mount Everest, Nepal and other countries use the total height of the snow cover height is 8848 meters, which is consistent with the measurement value of Mount Everest in 1975 by Chinese surveyors and mappers, and China uses the 2005 China State, the Surveying and Mapping Bureau measures the rock face height bare height, that is, the geological height is meters, and the elevation of the rock face of Mount Everest in 2005, the accurate determination and publication of meters have strict scientificity.

Strict legality, as the standard data used in China has been used so far, before the new Everest elevation data is released by the first or the first authorized department, any unit or individual should use the Everest peak published in accordance with the law, the top rock face elevation data meter On May 27, 2020, the 2020 Everest elevation measurement mountaineering team successfully reached the summit, the world's highest peak Mount Everest.

OK. The highest flying *** is the French SA 3158 type "American Ostrich"***. On June 21, 1972, pilot Jean Paulette flew the "American Ostrich" and set a world record for flying at an altitude of 10,000 meters.

The highest elevation of Mount Everest is about 8,500-9,000 meters.

Why can *** fly tens of thousands of meters in the air, but can't fly Mount Everest, which is only 8,848 meters high?

For safety reasons, it is generally not possible, and helicopters are not allowed to fly to the summit of Mount Everest.

Because at an altitude of more than 6,000 meters, the air will be very thin, and the rotors of the helicopter will not be able to obtain enough lift to stabilize the state of the aircraft.

If you want to solve this solution, you need to increase the horsepower to climb up, but because of the thin air, there is not enough oxygen in the engine of the helicopter, the aircraft will become very difficult, and it will not be able to provide too much power to the rotor of the aircraft, so it will not be able to achieve stable hovering and climbing of the aircraft, and it will not be able to fly to an altitude of more than 8,000 meters.

In addition, on Mount Everest, there are a lot of strong air currents, which may blow strong winds at any time, and the climate is extremely unstable.

Therefore, it is difficult for a helicopter to fly to the summit of Mount Everest, but at an altitude of five thousand meters, flying in these places is guaranteed to have no problems, because the helicopter itself also has the ability to fly at an altitude of six thousand meters, beyond which it is not so stable.

As a portable flight tool, it plays an important role in logistics, transportation, exploration and rescue, but due to structural problems, it cannot fly tens of thousands of meters in the air like passenger planes and fighter jets. If you raise the starting point and transport *** to the top of Mount Everest, can you break through the upper limit of flight altitude? The restricted altitude depends on the aircraft's ultimate level flight altitude.

Outside air pressure, air density and oxygen concentration will all affect the flight conditions. When the altitude is gradually increased, the air density gradually decreases, so that the amount of air entering the engine decreases, resulting in insufficient thrust. In this case, the ability to climb heights is limited and can only maintain level flight.

If it is forcibly raised, it will consume a lot of fuel, and the loss of the engine will be considerable. The general civilian *** can only reach 4000 meters, military aircraft can break through 6000 meters, the world's highest ascent limit, is a *** independently developed by China, creating a new record of 9000 meters, with great historical significance, directly beyond the height of Mount Everest. Mount Everest is as high as 8848m, and at the top of the peak, there is basically not much ground effect (*** is divided into ground effect hovering and no ground effect hovering), so at this altitude, most of the *** can not even take off, only a few *** can perform tasks at this height!

Common *** ceilings: Apache: 6400 meters, Black Hawk:

5700 meters, Hind: 4500 meters, Wuzhi 10: 6400 meters, Super Cobra:

3700 meters, tea falcon: 6000 meters, basically, the maximum flight ceiling is between about 5000-6000 meters, flying not high does not affect its mission, the biggest advantage of *** is hovering and flying close to the ground! The general ceiling of civilian aviation is 2000-4000 meters, and the military aircraft can reach more than 6000 meters higher, like the Z-9 of China's army aviation, with a maximum ceiling of 6000 kilometers and a maximum ceiling of 18 9000 meters.

The air at high altitude is thin, the efficiency of the engine and the rotor will be reduced, and if you want to go higher, you need supercharged equipment on the one hand, and a more powerful engine on the other. Because *** is most afraid of crosswinds, shear winds, which will lead to wrecks. The wind is strong on Everest.

Therefore, it is unrealistic to sit on Mount Everest, but it is still necessary to rescue in the mountains.

OK. But this is premised on the fact that the engine can remain working in a high-altitude and low-oxygen environment. In fact, the ceiling of ordinary civilian *** generally does not need to be too high, so the general *** actually can't fly to Mount Everest.

Of course, special treatment or need to fly in the plateau area should be able to do, in the final analysis, the main thing is the problem of the engine, which can keep it working under high-altitude and low-oxygen conditions to maintain stable power output, plus the structural strength of the fuselage is no problem.

It can fly, but it has to be specially designed and manufactured. There isn't much demand at the moment, and it's relatively expensive.

Ordinary *** can fly to 4000-5000 meters, and it is impossible to fly over Mount Everest.

So you can say yes or no.

Fixed-wing aircraft can now fly over Mount Everest with ease. Ordinary airliners, 737, 320 and so on will do.

Why can't you drive up Mount Everest?

Why can't you go up to Mount Everest?

It's because of part of the airflow, and then there is no way to directly climb to the top of Mount Everest, and the airflow near Mount Everest is already very complicated, and there is no way to fly here.

Because the air near Mount Everest is thin, the plane cannot fly, and the second is that the noise of the plane is too loud, which is easy to cause a blood collapse, so no one does the plane to the top.

It's also very difficult to get on a helicopter on Mount Everest, and the weather on Mount Everest is particularly harsh, so you need to have some time to get used to.

The plane cannot fly to Mount Everest because the altitude of the summit of Mount Everest is too high, the air is thin, and the rotors cannot provide enough power for the aircraft.

At altitudes above 6,000 meters, the air will be very thin, and the rotors of the helicopter will not be able to get enough lift to stabilize the aircraft.

If you want to solve this solution, you need to increase the horsepower to climb up, but because of the thin air, there is not enough oxygen in the engine of the helicopter, and it is impossible to provide too much power to the rotor of the aircraft, so it is impossible to achieve stable hovering and climbing of the aircraft, and it is impossible to fly to an altitude of more than 8,000 meters.

In addition, on Mount Everest, there are a lot of strong air currents of jujubes, which may blow strong winds at any time, and the climate is extremely unstable. Therefore, it is very difficult for the plane to fly to the summit. But the plane is guaranteed to fly at an altitude of 5,000 meters without any problems, because the plane itself also has the ability to fly at an altitude of 6,000 meters, and if it exceeds this altitude, the plane will not be so stable.

The principle of airplane flight

The cross-section of the wing of an aircraft is generally rounded and blunt at the front and sharp at the rear, with an arched upper surface and a flat lower surface. When equal mass air passes through both the upper and lower surfaces of the wing, it will flow at different velocities in the upper and lower squares of the wing.

The velocity of air passing through the upper surface of the wing is high and the pressure is small; When passing through the lower surface, the flow velocity is small and the pressure is strong, so the aircraft will have an upward resultant force, that is, the upward lift, due to the existence of lift, so that the aircraft can leave the ground and fly in the air. The faster the aircraft flies and the larger the wing area, the greater the lift generated.

The direction of gravity is the opposite of lift, it is a downward force caused by the gravitational pull of the earth, and the magnitude of gravity is affected by the weight of the aircraft itself and the amount of fuel it carries. The pulling force causes the aircraft to fly forward in the air, and the power of the engine determines the amount of pulling force. In general, the greater the engine output, the greater the thrust generated and the faster the aircraft can fly.

When the aircraft flies in the air, it is hindered by atmospheric molecules in the air, and this obstacle forms a drag force opposite to the direction of the pulling force, limiting the flight speed of the aircraft.

The altitude of the aircraft is very high, through the clouds, generally around 10,000 meters, it is generally believed that the plane should fly so high for many reasons, such as about 10,000 meters above the stratosphere in the atmosphere, 10,000 meters above sea level will not meet birds, and so on. If you want to know more about why planes fly so high, you can read on.

1. The altitude of about 10,000 meters belongs to the stratosphere, the stratospheric air resistance is small, and the airflow is relatively stable, which can not only reduce the amount of fuel of the aircraft, but also fly the aircraft more smoothly.

2. If the plane hits a bird during the flight, it will cause great damage to the aircraft, and the birds will not be encountered at an altitude of 10,000 meters to avoid accidents.

3. Looking out from the plane at 10,000 meters, the clouds you see are relatively stationary, and it is safer for the plane to fly at this altitude.

4. There is another important reason why the aircraft flies at an altitude of 10,000 meters, if the aircraft fails, compared with hundreds of meters and thousands of meters, the distance of 10,000 meters can give the pilot more time to solve the failure.

Airplanes can fly up Mount Everest. According to the data released by the Bureau of Surveying and Mapping, the height of Everest is meters, and the plane generally sails at an altitude of about 10,000 meters, so the plane can fly up Mount Everest.

Glad you asked, "Civil aviation is able to fly over Mount Everest, but there is no landing site." When the altitude exceeds 5,000 meters, the air flow is complex, and it is not easy to control its direction, and it is easy to turn off the engine because of the air pressure problem at an altitude of 5,000 meters, so it can not fly on Mount Everest. ”
