Ask a question about the plane, ask a few questions on the plane

You are asking about the proportional relationship between fuselage length and wingspan, right?

In fact, there is no direct relationship between the two. The aircraft's ability to fly comes almost entirely from the wings and tail, and the fuselage can be seen as a pure burden by and large. No matter how long or short the fuselage is, it has little effect on the wing.

The length of the fuselage is mainly limited by the overall design of the aircraft.

In general, the ratio of fuselage length to wingspan of subsonic aircraft is about 1:1, and the fuselage is generally slightly longer, in order to carry a little more things. For some older propeller aircraft, the fuselage will be designed to be slightly shorter in order to reduce the weight of the fuselage.

For fighters, in order to achieve supersonic flight, the wing frays are designed to be small to reduce drag, and at the same time, the rudder and elevator must be placed farther away in order to achieve greater aerodynamic trim and maneuvering moment, so the fuselage is longer. The ratio of fuselage length to wingspan of a fighter is usually around 2:1, or even higher.

A flying wing like the B-2 does not need a fuselage.

Looking at the usefulness of airplanes, supersonic aircraft all use short delta wings, and the lower the speed, the straighter the wings.

The designers of this different aircraft are not the same, there is no fixed proportion.

You can log in to the E-Travel Sunshine above to check the aircraft common sense.

The wing design of aircraft for different purposes is different.

It depends on what kind of aircraft you're asking?

As long as you are on the plane, you can't let the mobile phone have a signal, and the use of mobile phones by passengers will have an impact on the cabin pressure, magnetic direction, navigation and ground-to-air communication systems, which will seriously lead to yaw and crashes. So, don't let your phone have a signal when you get on the plane, you can choose the airplane mode, which is responsible for the safety of your life and that of other passengers.

It is possible to take photos with a DSLR, but for safety, secure the camera and fasten your seatbelt during take-off and landing to avoid hazards from bumps.

Don't bring too many duplicate things with the same thing, if the customs finds it, it will think that you are going to sell it, then it will not be clear to explain it at that time. Usually Thai customs will not check a lot, but it is better to be just in case. And don't go to declare.

You will go through immigration procedures first, and then you will collect your luggage. This idea is theoretically workable, because you don't have to worry about luggage, the staff will help you get to the baggage claim area. Especially at airports in Europe, these services are very considerate.

But in reality your plan is dangerous.

1. Do not wait in the arrival hall on the way to the arrival hall after getting off the plane, because customs and immigration management will be suspicious of your detention and will interrogate you. If you don't do it well, they have the right to refuse you entry. Because the visa only means that you can enter the country, the immigration authorities have the right to refuse your entry for many reasons.

After all, the last gate of entry is controlled and inspected by them.

2. If it takes too long for you to get off the plane to pick up your luggage, the immigration staff will still question you when reviewing your entry procedures. If you don't have a reasonable explanation, or if they don't accept your explanation, you may be denied entry. Because in fact, from the moment the plane lands, you are already in the country.

Hope it helps.

Hello, when the flight is stable, you can't turn on your mobile phone, you can't call, you can listen***, you can take pictures.

Fill in the form according to the quantity of digital products, and continue to take it in the baggage first.

It is not allowed to open a mobile phone on the plane, because the mobile phone signal is transmitted through the satellite, the plane can not see anything white in the sky, the flight depends on high-frequency satellite positioning, and communication system, the mobile phone will interfere with the signal, so that the aircraft GPS error, resulting in positioning confusion. As for wanting to listen to songs, you can pull out the SIM card of your mobile phone, put on headphones to listen, and you should be able to use digital to take pictures on the plane.

The general airplane cabin window is divided into three layers, and the one with small holes is the middle one.

The outer windows of the aircraft are pressure-resistant and can withstand certain impacts. During the flight, the cabin must be pressurized due to the thin air at high altitude, but even so, (the regulations stipulate that at the maximum flight altitude, the cabin pressure must not be lower than the equivalent of an external atmospheric pressure of 8,000 feet, which is equivalent to standing on the top of a mountain at 2,500 meters).

In order to avoid a long-term pressure difference between the three layers of glass due to the change of external pressure during the rise and fall process, this problem can be avoided by leaving a small hole in the middle glass for ventilation.

First of all, it's very simple, look at the first two letters of your ticket**, MU is China Eastern Airlines, CZ is China Southern Airlines.

When you change your boarding pass at the airport, you can check in at the check-in counter on the electronic display screen or at the check-in counter in English.

If there is only one airport in your city, you can check the name of the airport before going. If there are two airports, please refer to the flight ticket or e-ticket.

Airlines are stationed at one airport. But now many airports in central cities have two terminals, such as Shanghai and Guangzhou, please confirm which terminal is to board the plane, the terminal is abbreviated as T, for example, Terminal 1 is T1, 2nd T2.

In addition, you can make special requests when you board the aircraft, such as vegetarian or Muslim food, milk or allergy-free food. There are also those with children or disabilities who can sit in the front row.

If it's your first flight, you can chew gum to relieve tinnitus and eardrum pain during takeoff.

Usually the airport of a city is operated by multiple airlines, in the airport waiting hall above the check-in counter there are the logo and name of each airline, go to the airline check-in counter where you bought the ticket with your ID card, you can change the boarding pass and check in baggage. If the airport in the city is larger and has multiple boarding corridors, then generally every airline has a fixed corridor for boarding, so you should see the boarding gate marked on the boarding pass and board according to the designated boarding gate to avoid missing the flight.

As for which airline you bought the plane ticket, you should be clear when you buy the ticket, if you have an itinerary, or know the flight number of the plane, it can be identified from the first two characters of the flight number, Air China is CA, China Southern Airlines is CZ, China Eastern Airlines is MU, Sichuan Airlines is 3U, etc.

It is not that there will be many airlines at the airport of every city, but of course there will be many airlines in a provincial capital city like Kunming, and the general sales staff will tell you some information when you buy a ticket, if you buy a paper ticket, there will be relevant information on the ticket, such as airline, flight number, date, etc., if it is an electronic ticket, the relevant information will be told to you at the same time as you book the ticket, and you will also be prompted by text message later. If you forget, you can also dial their ** to find out.

After arriving at the airport, take your ID card to the corresponding airline window to change the boarding pass and check in your baggage. The domestic departures of Kunming Airport are on the second floor. The changed boarding pass will have the corresponding information, such as the security check, boarding gate, seat number, etc.

Another tip, if it is the first time to take a plane, it is good to try to change the boarding pass as early as possible, and ask the staff to change a window seat for you when you change, so that you can see the scenery outside the plane.

There are electronic displays at the airport that indicate which flight to change your boarding pass at which check-in counter, so you can just look at the airport electronic display or ask the staff.

CZ China Southern Airlines, ZH Shenzhen Airlines, MU China Eastern Airlines, CA Air China, FM Xiamen Airlines. SC Shandong, 3U Sichuan Airlines, HU Hainan Airlines, PN West, JD Golden Deer, EU United. What letters you see in the list of e-ticket carriers, such as CZ, stands for China Southern Airlines, and you can go directly to the China Southern Airlines counter at the airport to handle it!

Beauty, it's a pleasure to meet you, where is it, the airport of a city is the service desk of many airlines, to see the ticket ** mu is China Eastern Airlines CA is Air China CZ is China Southern Airlines HU is Hainan Airlines 3U is Sichuan Airlines SC is Shandong Airlines ZH is Shenzhen Airlines MF is Xiamen Airlines KY is Kunming Airlines 8L is Lucky Airlines.

There are many service desks of airlines at the airport of a city, for example, in Kunming, if I buy a ticket, I need to know whether it is China Eastern Airlines or China Southern Airlines to watch the big screen, find the service desk and take my ID card to change the boarding pass. Of course, many airlines board their planes at one airport.

2.Aircraft and people on board are usually only affected by gravity, that is, gravity. When the aircraft is maneuvering, such as making a turn, it will be affected by centrifugal force, and when accelerating, it will be affected by the force generated by acceleration.

This force is outside of gravity and is called an overload. In the unit of gravity, the gravity is 1g, and the aircraft is overloaded by 3g, that is, it is subjected to three times the force of gravity.

Maximum overload refers to the maximum additional overload that the aircraft can withstand on the structure or the personnel on board, beyond which the aircraft will lose control or the structure will be damaged, and the personnel will lose the ability to control the aircraft or even lose consciousness.

3.When the aircraft rolls and turns, the aircraft is subjected to the centripetal force, and the force of the aircraft is the resultant force of gravity and centripetal force, which is greater than the gravity of the aircraft, so it also produces overload, the faster the turning speed, the smaller the radius, and the greater its overload coefficient. Overload not only increases the force on the aircraft, but also has an impact on the occupants, and the maximum overload factor is given at the time of the design of the aircraft to limit the maneuverability of the aircraft.

For example, when the aircraft turns 60° sideways, the overload can reach 2. The overload of civil aircraft is limited to 3. Overloading of an aircraft when encountering gusts of wind or bumps or when poorly handled during landing can be significant, and pilots should handle it carefully to reduce overloading.

4.Ramjet engine. Impulse jet engine. Turbojet engine. Turbo ramjet engine. Turbine rocket engine.

5.A turbojet engine (it is often used at various speeds with a Mach number below 3) combined with a ramjet engine provides good performance at high Mach numbers. This type of engine is surrounded by a duct with an adjustable air intake in the front and an afterburner nozzle with an adjustable nozzle in the rear.

Take-off and acceleration, as well as in flight below Mach 3, the engine works in the same way as a conventional turbojet engine; When the aircraft accelerates above Mach 3, its turbojet mechanism is turned off, and the airway air bypasses the compressor with the help of guide vanes and flows directly into the afterburner nozzle, which becomes the combustion chamber of the ramjet engine. This engine is suitable for aircraft that require high speeds and maintain high Mach number cruising conditions, where the engine works as a ramjet engine.

I've been checking for a long time, I don't know if it's right, there's only so much I hope it can help you, Happy New Year's Day

The overload is generally 9g

This is the maximum g-force.

G is a gravity, for example, if you weigh 150 pounds, the gravity on your body when you are 2g will have 300 pounds and the car turns.

The pilot can withstand a short period of 9g

At the time of the crash, it can be as high as hundreds of grams in an instant

1.The ticket price from Harbin to Shenyang varies from airline to airline, with a full ticket of 510 yuan and a discount of 260 yuan to 480 yuan.

2.You can book your ticket at a ticket office, by calling the airline's booking**, or through the airline's website, just tell them your destination and choose the time of your stupid flight.

3.Find discount tickets online.

4.The cabin of the plane is divided into first class business class economy class, and some may only have two classes, first class is the most comfortable followed by business class but the ticket price of these two classes is much more expensive than economy class first class is the most expensive.

5.Passenger planes are generally flying at altitudes above 8,000-10,000 meters, and of course you can see clouds when there are clouds, because the planes are flying above them.

Children don't seem to need anything, 2 kilograms of things can be brought to the flying key calendar, the spring and autumn rotten ruler is considered to bring less, but 2 kilograms should also be possible, I went back to Shanghai the day before yesterday, the plane of Shanghai Airlines, my bag of things is estimated to have six or seven drafts of Zheng Jin weight, no problem.
