Can the plane fly in the troposphere or stratosphere currently the best aircraft in the world .

Airplanes are not only flying in the stratosphere, but it is safer to fly in the stratosphere.

The layer of atmosphere closest to the ground is known as the troposphere. Because the energy contained in this layer of the atmosphere comes mainly from absorbing long-wave radiation from the ground, the farther away from the ground, the cooler it becomes. In daily life, the temperature on the mountain is lower than at the bottom of the mountain, which is the reason.

The air temperature close to the ground in the troposphere is high, the gas is easy to expand and rise when heated, and the temperature in the air is low, and the gas is easy to shrink when cold, so there is a reciprocal air convective movement (this is the origin of the name of the troposphere). As the air near the ground rises, the temperature becomes lower, and the water vapor contained in it condenses and is prone to clouds and rain.

As a result, the troposphere is not a very suitable layer for flying, because it is full of air movements and complex weather conditions.

On the contrary, the stratosphere, which is located above the troposphere, has its energy mainly due to the fact that ozone absorbs ultraviolet rays from sunlight. Therefore, the farther away from the ground, that is, the closer the air is to the sun, the higher the temperature. That is, in the stratosphere, the change in temperature is exactly the opposite of the troposphere:

The higher the altitude, the higher the temperature. Gases at higher temperatures are lighter, on top; Cooler gases are heavier, below. This is a relatively stable state.

Therefore, in the stratosphere, there is rarely a convection of air up and down, and the air flow is mainly horizontal, which is the origin of the name stratosphere.

Because in the stratosphere, there is very little air convection movement and the higher the temperature rises, there is no condensation of water vapor in the updraft, so the stratosphere is always clear and cloudless, and the visibility is very high. Coupled with the airflow that rarely moves up and down, the aircraft is less prone to turbulence when flying in it. Therefore, modern flights always climb higher and higher after takeoff, until they cross the troposphere and enter the stratosphere, and then they start to fly horizontally.

Fighters can fly, civil airliners generally fly in the stratosphere, in order to obtain stability and comfort, but the troposphere can also fly.

Large planes fly in the stratosphere, small and medium-sized ones can't fly that high, all in the troposphere.

The plane landed safely.

Airplanes fly in the upper stratosphere, in the troposphere.

Airplanes generally fly in the upper stratosphere and troposphere. Theoretically, airplanes fly most smoothly in the stratosphere. However, because there are many planes in the sky, the planes need to fly according to the specified altitude and route to avoid collisions, so the specific flight altitude needs to be according to the instructions of local control.

Human aviation activities are almost concentrated in the troposphere and stratosphere, and in order to ensure the efficiency of aircraft and engines, the altitude of aircraft flight is generally not more than 30 kilometers.

Features of the troposphere:

The main characteristic of the troposphere is that the air temperature decreases with increasing altitude, so it is also known as the thermosphere, and on average the air temperature decreases for every 1,000 meters of altitude rise. At the same time, the air pressure decreases with altitude. Because almost all the water vapor is concentrated in this layer of the atmosphere, plus a large number of particles, it is also the most volatile layer of wind and clouds.

From an altitude of about 11,000 meters until about 30,500 meters is the stratosphere, also known as the stratosphere, whose atmospheric temperature is basically unchanged and remains up and down on average.

There is almost no water vapor in the atmosphere in this layer, and there are basically no meteorological changes such as clouds, fog, rain, hail, etc., which is very beneficial to the smooth flight of the aircraft. However, due to the low density of the air, the aircraft is not suitable for maneuvering at this altitude level.

The planes are all in the stratosphere.

There are several reasons for flying, first of all, the air flow here is more stable, and it is safer for aircraft to navigate. Secondly, the air pressure here is also within the tolerance range of the plane, if it is too high, even the person who flies will have problems, and finally it can avoid certain dangers, such as thunderstorms and birds.

The process of aircraft flight is generally relatively smooth, that is, because the plane flies in the stratosphere, the altitude is about 7000 12000 meters, the specific altitude should be changed according to different latitudes, where the airflow is relatively stable, there will be no turbulence, which is relative to the troposphere.

In other words, because the troposphere is mostly cold and hot air meet, the air flow is very chaotic, and if the aircraft encounters this air flow when flying, the probability of danger will be greater.

For every 1,000 meters of altitude ascent, the temperature drops by degrees Celsius.

Therefore, the stratosphere of the aircraft also has a limit, and it also involves problems such as air pressure and aircraft loss, but if it flies too low, it is easy to encounter thunderstorms, fog and other weather, so when the aircraft flies, the altitude will be changed according to the specific situation, and the process will be gradual, otherwise it will suddenly fall sharply, which will cause harm to the body of the passengers. Of course, when changing the altitude, we will also communicate with aircraft that are on the same route or have intersections to avoid collisions.

Because because the planes fly high enough, the oxygen is thin here, and there are generally very few birds flying, and in addition to this, there are some *** and hot air balloons.

It also flies at low altitudes, so flying in the stratosphere avoids encountering these uncontrollable factors. But there are no absolutes, and there are some clouds that are too thick, accompanied by thunderstorms.

In this case, the plane has to fly as close to the clouds as possible, because it is often accompanied by strong air currents, which have an impact even greater than the troposphere.

Because the height of the stratosphere is suitable, there is no risk of hitting the mountain, the noise is relatively small, and the stratosphere is stable and not easy to be impacted.

Because the stratosphere is the most stable. Best for your normal flight, so the plane is generally flying in the stratosphere.

Because the stratospheric airflow is relatively stable, aircraft are the safest because they experience the least fluctuations in this atmosphere.

Airplanes generally fly in the upper stratosphere and troposphere.

Theoretically, the plane flies most smoothly in the stratosphere, but because there are many planes in the sky, the plane needs to fly according to the specified altitude and route to avoid collision, so the specific flight altitude needs to be according to the instructions of local control. Civil airliners are supposed to fly in the upper troposphere, but military aircraft can often fly in the stratosphere.

Civil aircraft generally fly at an altitude of 7,000-12,000 meters after takeoff, and some fighters can fly at an altitude of 30,000 meters. It can be seen from this that in fact, for civil aircraft, most of the time is at the top of the troposphere or at the junction with the stratosphere, and part of the time at the bottom of the stratosphere. Fighters can fly in the lower stratosphere (i.e., the stratosphere), generally at altitudes of no more than 30,000 meters.

Main features of the troposphere

1. The temperature decreases with the increase of altitude. This is mainly because the vast majority of the heat in the tropospheric atmosphere comes directly from the ground, so the higher the atmosphere above the ground, the less heat it receives and the lower the temperature. On average, every 100 meters of ascent, the temperature drops by degrees Celsius.

2. The air convection movement is significant. The upper part of the troposphere is cold and the lower part is hot, which is conducive to the convective movement of air. The low latitudes are heated more, the convection is vigorous, and the troposphere reaches a high height. The high latitude area is less heated, and the lower the trospheric height of the grinding key silver.

3. Weather phenomena are complex and changeable. The water vapor and impurities near the ground are transported upward by convection, and with the decrease of air temperature during the lifting process, it is easy to form clouds and cause rain. Weather phenomena such as clouds, rain, and snow all occur in this layer.

In the stratosphere, large passenger aircraft mostly fly in the stratosphere to increase flight stability. The reasons are: High visibility: The stratospheric water vapor, suspended solid particles, impurities, etc. in the earth's atmosphere are very small, the weather is relatively clear, the light is relatively good, and the visibility is very high, which is convenient for high-altitude flight.

The stratosphere is stable under force, the atmosphere of the stratosphere is warm and cool, the atmosphere is not convection, and the stratosphere is mainly in the stratosphere.

Mainly in the troposphere, there are not many times to fly in the stratosphere, mainly long-distance flights such as intercontinental flights will reach that height. The country is mainly troposphere.

The maximum flight altitude of different aircraft short-route aircraft generally flies from 6000 meters to 9600 meters, and the aircraft of long routes generally flies from 8000 meters to 12600 meters, and the maximum flight altitude of ordinary civil airliners will not exceed 12600 meters, so that the flight altitude of some business jets can reach 15000 meters.

Aircraft in the cruising state consume the least amount of fuel per unit distance; At the same time, the maximum range of the aircraft is calculated according to the cruising speed, and even the transfer range of the fighter is calculated according to the cruising speed of the aircraft.

So cruising is the most fuel-efficient segment of an aircraft's flight, which occurs between climb and descent, that is, when the aircraft is close to the concession and enters the descent position to prepare for landing, which usually takes up most of the flight time.

The plane landed smoothly and safely.

Civil aircraft generally fly in the stratosphere during the cruising phase, which mainly has the following benefits:

1. Stable force The atmosphere of the stratosphere is warm and cool, the atmosphere is convection, and the advection movement is the mainstay, and the force of the aircraft is relatively stable in it, which is convenient for the pilot to control the frame;

2. High visibility The stratospheric water vapor, suspended solid particles, and impurities in the earth's atmosphere are very few, and the weather is relatively clear, the light is relatively good, and the visibility is very high, which is convenient for high-altitude flight;

3. High safety factor The height of the bird flight generally does not reach the stratosphere, and the aircraft is safer to fly in the stratosphere. Of course, when taking off and landing, it is safer to find ways to drive away the birds;

4. Low noise pollution The stratosphere is high from the ground (about 12km 50km), and the aircraft flies in it most of the time, so the noise pollution to the ground is relatively small.

This layer of air from the ground to within 10 12 kilometers is the lowest layer of the atmosphere, called the troposphere. Major weather phenomena such as clouds, rain, snow, hail, etc., occur in this layer.

The layer above the troposphere, up to about 50 kilometers high, is called the stratosphere. The air in the stratosphere is much thinner than in the troposphere, and there is very little water vapor and dust sourceslip, so there are very few weather phenomena.

From above the stratosphere to 80 km, some call it the mesosphere, and the temperature in this layer decreases with altitude.

The space in the layer above 80 km to about 500 km is called the thermosphere, and the temperature in this layer is very high, and the day and night vary greatly.

The layer that starts about 50 kilometers above the ground and goes about 1,000 kilometers high is called the ionosphere. Beautiful auroras appear in the ionosphere.

It is the outermost layer of the atmosphere, the transition area of the atmosphere to interstellar space, and there is no obvious boundary outside. Under normal circumstances, the upper limit is lower near the geomagnetic pole, and the near-magnetic equator is on the sun-oriented side, about 9 10 Earth radii high, in other words, about 65,000 kilometers high. The air is extremely thin here.

Usually within 1,000 kilometers, that is, within the ionosphere, as the altitude of the atmosphere, that is, the atmosphere is 1,000 kilometers thick, and the aircraft is suitable for flying in the stratosphere.
