I didn't expect you to be an ignorant person, you also believe, so that the airplane is almost all inflatable tires except for the model airplane, that is, the space shuttle is also an inflatable tire, the aircraft tire is composed of multiple layers of cord, can withstand a strong impact, due to the high load, the tire pressure will be much higher than the car tire, the commercial aircraft is generally filled with nitrogen, tubeless design, the landing gear of the aircraft itself is the pursuit of small, light, high load, because if they are solid tires then, you calculate how heavy it will be, too big for the aircraft. Don't think that the heavy impact of the plane is not inflatable. I hope you don't be misled by others, it's ridiculous to be able to say that airplanes use solid tires.

Aircraft tires mostly use tubeless, double-tread tire structure, which is tubeless. Two layers of special cords are added to the inside of the aircraft tire tread rubber, commonly known as "reinforcing cord layer". With the ply layer as the boundary, the tread rubber is divided into the outer layer of tread rubber and the inner layer of tread rubber, and when the tire is worn to expose the second layer of particle, it will be scrapped.
The rubber surface of the aircraft tire is made of abrasion-resistant and high-temperature resistant special material glued steel wire, about 20 mm thick, with high strength, and the tire valve is both pointed and short, made of high-temperature fluoroplastic, with smooth air intake and strict leakage.
Aircraft tires do not have inner tubes, mainly because they are convenient for disassembly and maintenance, and they can be directly inflated into the tires when flying. At the same time, airlines around the world use high-strength magnesium-zinc alloy to make the wheel hub and movable wheel rim, and use the sealing ring to seal the joint part of the wheel hub and the movable wheel rim, between the valve and the wheel hub, which can ensure that the gas in the tire up to several atmospheric pressure values does not leak, and its performance is incomparable to that of ordinary tires, and it is quite expensive.

Do you know whether the tires of a fighter are solid or hollow?

Aircraft tires generally have a tubeless, twin-tread structure, which means that they are not solid tires.
It is reported that the aircraft adopts a tubeless design, mainly to facilitate disassembly and maintenance, and can directly inflate the tires before the flight, and the high-strength sealing ring of the tires can ensure that the gas in the tires is up to several atmospheres without leakage.
In addition, aircraft tires are filled with nitrogen. Compared with air, the volume change of nitrogen thermal expansion and contraction is smaller, and the inert gas can also protect the tire material from oxidation to a certain extent, and its non-flammable and non-combustible characteristics can increase the safety factor.
Taking the Boeing 777 aircraft as an example, the total weight of the aircraft before take-off is about 300 tons, and these weights are mainly borne by the 12 wheels of the main landing gear, with an average of 25 tons of weight per wheel.
At the same time, the take-off speed of the aircraft is 300-350 kilometers per hour, the landing speed is more than 200 kilometers per hour, and the tires of the aircraft are subjected to strong vertical shock loads, as well as friction loads when accelerating horizontally.
One thing that is very different from car tires is that car tires are usually insulated, but aircraft tires need to have good electrical conductivity. In this way, when it lands, it can release the static electricity generated by the friction between the fuselage and the air.

The tires of all kinds of cars that we usually come into contact with are basically inflated, and for airplanes flying in the sky, do the tires used in it also have to be inflated?
-
The tires used in airplanes are actually inflated. However, depending on the situation and the different flight speeds, the gas that can be filled inside may be different.
As an important type of aircraft, the tires used in fighter jets are more resistant to wear and tear than those used in other aircraft.
Because not only does the fighter have the same configuration as other aircraft, it also hangs on the ** and equipment used by the team. So it weighs more than an ordinary civilian aircraft. Therefore, it can only use more wear-resistant and high-temperature resistant materials to make the tires it needs.
Aeroplane (airplane) refers to a heavier-than-air aircraft with one or more engines that generates forward thrust or pull, and lift is generated by the fixed wings of the fuselage.
The airplane is one of the most significant inventions of the early 20th century, recognized as invented by the American Wright brothers. Their flight on December 17, 1903, was recognized by the Fédération Internationale de Nautical (FAI) as "the first controlled, sustained powered flight of a heavier-than-air aircraft", and in the same year they founded the Wright Aircraft Company.
Since the invention of the airplane, the airplane has increasingly become an indispensable tool of modern civilization. It profoundly changed and affected people's lives, and opened the history of people's conquest of the blue sky.

Do you know whether the tires of a fighter are solid or hollow?
-
Aircraft tires are also the same as those on ordinary cars, which are hollow. It is also divided into inner tube and outer tire, the tread rubber of the outer tire is relatively thick, there are eight layers of line inside, even if it is a new tire just installed on the plane, as long as the part of the tire grounded, due to the friction of the landing, there is an exposed line, like a jujube, it must be replaced.

Aircraft tires are not solid.
Most of the aircraft tires use tubeless, twin tread tire structure, so it is not solid, two layers of special cord are added inside the aircraft tire tread rubber, commonly known as the reinforcing cord layer, with the cord layer as the boundary, the tread rubber is divided into the outer layer of tread rubber and the inner layer of tread rubber, when the tire is worn to expose the second layer of the cord, that is, scrapped.
The rubber surface of aircraft tires is made of wear-resistant and high-temperature resistant special materials glued steel wire, aircraft tires without inner tubes are mainly convenient for disassembly and maintenance, when flying, you can directly add air to the tires, at the same time, airlines around the world use high-strength magnesium-zinc alloy to make wheels and movable wheel rims, and use sealing rings to seal the joint parts of the wheel hub and movable wheel rims, valves and hubs, which can ensure that the gas in the tires is up to several atmospheric pressure values does not leak.
Aircraft Tire Pocket Principle:
When the aircraft is in contact with the ground, the tires will generate a lot of heat due to friction, so the tires of the aircraft have super high temperature resistance, and when the friction with the ground occurs, this tire has low heat generation. When the fighter plane lands, the ram will reach several gigapascals, so it has ultra-high impact resistance, and the tire wall of the aircraft is much thicker than the tire wall of the car, and the wear resistance is relatively better.
When a civil airliner lands, the impact force on the runway is as high as several hundred tons, which brings great pressure to the tires and will cause great deformation and wear. At this time, if the aircraft tires are added with transverse lines, the strong impact and friction force when landing, it is easy to tear the transverse lines on the tires, reduce the service life of the tires, and bring potential safety hazards, and the longitudinal lines can improve the lateral friction of the aircraft and prevent the aircraft from sliding out of the runway during the take-off and landing stage.

Aircraft tires are hollow.
Aircraft tires are usually made of multiple layers of rubber and other materials with an air filling inside. This design helps to reduce the weight of the aircraft and provides better shock absorption and cushioning. Solid tires may have been used in the past, but modern aircraft tires are generally hollow and car-sided.
The inside of the hollow tires is filled with air, which can provide better elasticity and shock absorption during take-off and landing, making the aircraft more stable and comfortable during take-off and landing. In addition, hollow tires can also adjust the internal air pressure as needed to suit different flight conditions and load requirements.
Aircraft tires need to withstand high speeds, heavy loads, and complex landing and take-off conditions, so they need to be strong and durable. Tire materials are usually made of high-strength rubber and reinforcing belts, which can withstand high-speed rotation and heavy loads.
Features of aircraft tires
1. Anti-wear and corrosion-resistant: Aircraft tires will have friction and wear with the ground during take-off and landing, so they need to have strong anti-wear performance. At the same time, tires need to be able to resist chemicals and oils to maintain good service life and performance.
2. High temperature resistance: Since aircraft tires will produce high temperatures due to friction during take-off and landing, they need to have good high temperature resistance. Tire materials need to be able to withstand deformation and expansion at high temperatures without degrading or damaging performance.
3. Crash resistance and explosion protection: Aircraft tires need to be able to withstand external impacts and impacts, as well as prevent bursting. Tyre construction and materials are typically used to stabilize in the event of an impact and avoid tire breakage or**.
4. High precision and balance: Aircraft tires need to have high-precision manufacturing and balancing performance to ensure the stability and stability of the aircraft during high-speed operation. The manufacturing process of tires requires precise control of size and weight, as well as precise balancing.
Fixed-wing aircraft refers to a heavier-than-air aircraft with wings and one or more engines that can fly in the atmosphere by its own power. Strictly speaking, an aircraft is an aircraft with fixed wings. At the beginning of the 20th century, the Wright brothers of the United States made significant contributions to the history of aircraft development in the world. >>>More
Airplanes are heavier-than-air aircraft, so they need to expend their own power to gain lift. And the ** of lift is the effect of air on the wing in flight. The upper surface of the wing is curved and the lower surface is flat, so when the wing is in relative motion to the air, the air flowing through the upper surface travels a distance (s1) in the same time (t) than the air flowing through the lower surface (s2), so the relative velocity of the air on the upper surface is faster than the air on the lower surface (v1 = s1 t> v2 = s2 t1). >>>More
The airplane was invented on December 17, 1903 by the Wright brothers, American inventors. On December 17, 1903, the Wright brothers made their first test flight of a fully controlled, self-propelled, heavier-than-air fuselage, and continuously stuck in the air, that is, the world's first aircraft, the "Flyer One". >>>More
The miniature vacuum pump mainly refers to a device with an inlet and an exhaust nozzle, the working medium is mainly gas, and the vacuum or negative pressure can be continuously formed at the inlet, and the slight positive pressure is formed at the exhaust nozzle, and the volume is small. Therefore, Pronuok vacuum technology is simply said: its working principle is mainly to discharge the air pressure in the container under the action of pressure difference.
Anyone who has learned about flow rate should know it. The pressure is small where the flow velocity is large, and the upper side of the wing is convex, so that a strong flow velocity can be generated when the aircraft is flying, the pressure is reduced, and the lower part is smooth, so the pressure is greater than the above, and the upward support force on the wing will be formed, which is the lift, if the aircraft thrust is greater, the lift will be greater.
