How high can an airplane fly, and can it fly into space without taking into account fuel consumption

The lift of an airplane is generated by the pressure of the air, and the fuel engine of the aircraft also consumes oxygen. Since the density of the atmosphere decreases with the increase in altitude, there is no oxygen in space, so the plane flies at an altitude.

Generally, it will not exceed 20,000 meters, and the flight altitude of passenger aircraft will not exceed 15,000 kilometers. You can't fly into space.

Airplanes are usually jet, the altitude will not exceed 12,600 meters, jet engines need oxygen combustion to generate power, the higher the environment at high altitude, the lower the oxygen content, when the aircraft can not get enough oxygen, the power it produces will naturally weaken, the height of the aircraft will begin to fall, is not able to fly into space. ‍‍

I think that if you seriously accelerate before leaving the atmosphere, so that you can move forward by inertia, you should be able to fly into space, this place belongs to the subspace region, the atmospheric escape layer, the Americans have done it, and the specific altitude is forgotten, it seems to be 80 kilometers. If the speed is fast and slides into the microgravity environment of the vacuum airspace, the problem is complicated. If you want to come back, you can only wait, wait for the stall to free fall to the oxygenated layer and fly back.

There's also the problem that the pilot has to bring enough food and water to deal with the excretion problem, and you don't know how long he can stay in space.

Generally, the flight is about 12,000 meters, and the plane cannot fly in space, because the plane cannot fly in a vacuum environment.

The flight altitude of this kind of aircraft is generally about 10,000 meters, and the power is generally jet, so the reason why civil airliners can fly, fuel is naturally an indispensable part, but in fact, the air in the atmosphere is the most critical factor for the aircraft to take off. But the higher you go in the sky, the thinner the air becomes, and ordinary airplanes can't fly out of the atmosphere.

The altitude of the aircraft is generally between 7,000 meters and 12,000 meters, and the aircraft cannot fly into space.

The high flight altitude does not exceed 12,600 meters, and there are some business jets that can fly up to 15,000 meters. Airplanes can't fly into space. ‍‍

Civil airliners generally do not fly more than 5,000 meters, and it is unrealistic to need oxygen equipment at higher levels, and such aircraft cannot fly into space.

Most of the fighters in service have an effective flight altitude of about 18,000 meters. No matter how high it is, it can fly up, but the performance will be greatly affected.

The flight principle of the aircraft is based on the lift of the air; Engines include turbine engines, turbofan engines, ramjet engines, etc., which rely on air as an accelerant. In a vacuum, there is no air, and the plane will not rise.

Never, unless you bring an incendiary agent. Otherwise, it can only be in the atmosphere.

It's impossible for an airplane to fly into space, and to get out of the Earth's gravitational pull to fly through the atmosphere, to reach the first cosmic velocity, which the airplane is nowhere near capable of escaping.

In fact, on this issue, we also have to look at what kind of aircraft it is, not all of them can be assumed in this way. If it is an ordinary civil airline, then no matter how much fuel you give him, he will not be able to fly into space, but if it is a space shuttle, then it can definitely fly in, because the working principle of these two planes is completely different. Naturally, there will be a big difference in their functions and performance, and there are many people who don't understand the difference, so let's talk about it now.

Everyone knows that civil airliners generally only fly at about 10,000 meters at this altitude, and their power is that kind of jet. Fuel is an indispensable part of what he flies. But in fact, there is a more important thing, that is, the air in the atmosphere, which is an important key factor in whether an airplane can take off.

There is a characteristic of the airliner, that is, the design of its upper and lower wings must be different, this is because when they take off, they will need to gain an upward force in order to be able to fly. The higher you fly in the sky, the thinner the air becomes, and if you can't get a pressure difference, then you can't fly, but there is no air in space, and ordinary models can't fly out of the atmosphere at all.

The spaceplane is different, although he says it is called an airplane, but it is a kind of spaceship, and the reason why he can enter the sky is because of his recoil movement. When they take off, they will fly towards the ground with a high-speed air current, which will give them a very strong force in the opposite direction. In the case of recoil movement, he does not need any air, nor does he need to say how strong the support is.

So from here we can see what kind of model can fly into the sky, and what kind of model can't.

Even if there is enough fuel, it cannot fly into space, because the overall structure of the aircraft cannot actually break through our earth at all, and only this rocket made by us can rush into the sky.

If the plane has enough fuel, it will not be able to fly into space, because the energy and fuel volume of the plane are not enough to fly well into space, and space has no gravity.

No, because airplanes don't have this function, they can only maintain balance in the air, and even if they have enough fuel, they can't fly into space.

First, the airplane is able to fly because the wings of the airplane (or the wings of the airplane) interact with the air to produce upward lift, so as the plane flies higher and thinner, the air becomes thinner and thinner (in fact, there is less and less air), and finally the wings of the airplane will no longer be able to generate lift.

If there is no upward force to lift the plane, then the plane will naturally not be able to fly. So this is one of the reasons why current airplanes are not able to fly into space.

Second, the power of the aircraft** is the aircraft engine, and the operation of the aircraft engine requires oxygen. As shown in the figure below, it is the working principle of the turbofan engine on the aircraft, and the reason why such an engine can work is that the aero engine inhales oxygen, and then lets the oxygen and aviation kerosene mix and burn in the combustion chamber to finally produce energy and drive the aircraft.

And after arriving in space, there is no oxygen, and the aircraft engine naturally "can't catch fire", loses power**, and of course, there is no way to continue flying. Rockets are able to fly in space because the rocket engine has its own fuel and oxidizer (as shown in the image below), so it doesn't need to draw oxygen from the surrounding air – which works completely differently than an engine on an airplane.

So are there any planes that can go into space? In fact, there are, for example, the familiar space shuttle, which is actually an airplane that can fly into space. But the space shuttle did not fly into space on its own, but "sent" him into space by rockets [as shown in the picture below].

In the future, it is possible that humans will build airplanes that can fly into space, but at least the engines will need to be greatly changed. For example, the picture below shows a hybrid engine called Saber, which can be used in the atmosphere and can be transformed into a rocket engine outside the atmosphere, and this engine is intended for future aerospace aircraft.

As the topic suggests, let's discuss whether an airplane can fly into space.

The main body of the topic is an airplane, that is, a heavier-than-air aircraft that has one or more engines that produces forward thrust or pull, and the fixed wings of the fuselage generate lift, and flies in the atmosphere. At present, the exploration of human beings flying into space is mainly realized by spacecraft, that is, various types of vehicles that operate in space in accordance with the laws of celestial mechanics and perform specific tasks such as exploration, development, and utilization of space and celestial bodies. Obviously, there is no necessary conditional connection between the subject and the verb of the question.

Answer: Beihang people, often misunderstood whether it is "Beijing University of Aeronautics and Astronautics" or "Beijing University of Aeronautics and Astronautics" ......The answer is in the diagram below).

Let's seriously discuss this issue again, in fact, it is still very possible, or inevitable, for "airplanes" to fly into space in the future, but the limitation does not lie in the amount of fuel. The aerospace aircraft is the product of mankind's highly integrated aerospace technology for the future, which can be used as both aviation and spaceflight, integrating aircraft, space launch vehicles and spacecraft, and can also be used as manned spacecraft and can be reused. Compared with the current traditional aircraft, the future aerospace aircraft will be optimized for hypersonic flight in terms of aerodynamic shape, but the most critical difference lies in the design of the power system, that is, the power system has the characteristics of both aero engine and rocket engine, which can be summarized as a combined power mode of turbojet + ramjet + rocket engine.

The aerospace engine can take off without using additional rocket boosters, and can take off from the airport runway like a traditional aircraft, and then fly in the atmosphere at hypersonic speed, accelerate to a sufficient speed and go directly into space, and at the same time use the rocket engine to power the spacecraft, which can also land on the airport runway like a conventional aircraft when landing.

In the end, no matter what, the human quest for flight never ends!

I can do anything, space also has air pressure, such as the earth pressure is different, the earth is gravitational pressure, space is space pressure, such as a balloon, gravitational pressure airplane such as flying outside the balloon, space pressure is such as an airplane flying in a balloon, want to fly out of the earth aircraft engine is as big as the existing aircraft engine, increase the thrust pressure, you can fly out of the earth. As long as there is that kind of material, nuclear fusion alloy carbon, installed in an aircraft engine, and heated with electric atoms, it will produce nuclear fusion to produce hot gas energy, produce strong thrust, and it is not impossible for the plane to fly out of the earth.

Even if there is enough oil, the plane will not be able to fly up, and in terms of current science and technology, there is no way for the country to fly into space, and I believe that one day there will be such a possibility.

I don't think so, as a non-professional, let me talk about it from my usual experience, everyone may have seen the kind of pictures and news on TV, the rocket launched into space.

If ordinary airplanes can fly directly into space, why develop rockets to propel spacecraft.

The plane takes off by the air flow on both sides of the wings, and the higher you go, the thinner the air, and the plane has to break free from the earth's gravity to fly into space, it is obvious that the current speed of the aircraft and the power of the fuselage are still far from enough. So I personally think that airplanes can't fly into outer space.

It's impossible, our technology is not up to it yet, and now we can only go to space by spaceship. Aircraft engines rely on oxygen, and there is no oxygen when you go out into space, so no matter how much fuel you have, you can't go to space.

No, because the ascent of the aircraft is supported by air, and the farther away from the ground the air becomes, and when it is too thin, there is not enough air to support the ascent. Now the engine is not developed enough, it has not reached the point where it can work without relying on air.

No, the power of an airplane** is the aircraft engine, and the operation of the aircraft engine requires oxygen. The engine works because the aero engine inhales oxygen, and then lets the oxygen and aviation kerosene mix in the combustion chamber to produce energy and drive the aircraft.

First of all, everyone should understand that the flight altitude of this kind of aircraft is generally about 10,000 meters, and the power is generally jet, so the reason why civil airliners can fly, fuel is naturally an indispensable part, but in fact, the air in the atmosphere is the most critical factor for aircraft to take off.

This is impossible classmates, there is an atmosphere on the surface of the earth, maybe you haven't learned this knowledge, I can help you increase your knowledge, there is an atmosphere on the surface of the earth that requires an airplane to pass through at a very high speed, but the general surface material of the airplane does not allow the plane to do this.

Can an airplane fly out of space with enough fuel? Look at the way the rocket flies, understood.

In fact, many planes cannot fly at an altitude completely devoid of oxygen, and they are already unable to climb, because the air is too thin to provide enough lift to the aircraft to climb, and if you force your head up, it will only lead to a stall, and the serious result is a crash. Except for the extreme several aircraft, the first is the U2, which has a thin and slender fuselage, huge wings, and a high lift-to-drag ratio, even in extremely thin air, he can slowly climb up. The other is the Blackbird, including the MiG-25, the MiG-31 is also counted, relying on the power of the engine to obtain better high-altitude performance, generating fast enough speed to maintain lift, and the extreme altitude is basically above the Mach to ensure that the altitude is not lost.

Even so, their ceiling is limited, and it is impossible to fly fifty or sixty thousand meters. Rockets can go into space because the principle is different, the rocket is propelled by reaction force, the fuel carries its own oxidizer, and the thinner the rocket in the air, the smaller the resistance, the more it can fly, the more fuel-efficient, and the opposite of the aircraft.
