Is the core technology of an aircraft carrier a runway?

1. Aircraft carrier deck technology. When the aircraft takes off and lands, a flame with a temperature of more than 1,000 degrees is sprayed from the tail nozzle and burned directly to the deck, requiring the aircraft carrier deck to withstand high temperatures, not deformed, and good materials.

Second, catapult technology. An aircraft carrier is a ship, and it is impossible to build a very long runway like land, and the longest runway is only more than 200 meters. Due to the short runway on the aircraft carrier, the aircraft had to be ejected with a catapult.

The catapult is like a bow, and the plane is like an arrow on the bow, and the catapult is used to shoot the plane. Due to the high monopoly of catapult technology in the United States and its strict secrecy, no other country has seen it except the United States and France. (It is said that the former Soviet Union has developed it, but it is not equipped).

3. Carrier-based aircraft. An aircraft carrier is a ship, and it cannot be as large as a land airfield, and it is required that the planes on board the ship be small in size and foldable in wings. It must have the performance of short take-off and landing, but also be able to resist the corrosion of seawater and adapt to the marine climate. Therefore, carrier-based aircraft are more difficult to build than land aircraft.

Fourth, various radars on the ship. Aircraft carriers have a lot of radars on them.

5. Engine. The engine of the carrier-based aircraft requires an adjustable nozzle (the nozzle can be steered). Make the aircraft take off and land short.

Sixth, the machine line. When the plane lands, a wire rope should be used to reduce the distance of the aircraft to run. This wire rope is difficult to build.

Aircraft carriers do not have core technologies.

The aircraft carrier is a comprehensive system, and each subsystem is very important, and there is no distinction between primary and secondary. It's just that relative to countries that do not have aircraft carriers, which technologies are not mastered by others, such as the manufacturing technology of steam catapults, which is the embodiment of the level of metallurgy and processing technology; There are also special alloy steel plates, steam turbines, navigation and positioning. If the aircraft carrier cannot be located, its carrier-based aircraft cannot navigate autonomously.

Just like the air defense system, it cannot be said that radar or missiles are more important, which is the core technology.

Upstairs we're talking about an aircraft carrier battle group, which is a huge system. It involves not only technology, but also the issue of command and training coordination.

No, the aircraft carrier is not only an aircraft carrier, but for the preparation of the entire aircraft carrier battle group, the aircraft carrier is equivalent to a central platform, there are warships (destroyers, etc.) on the left and right, there are submarines below, there are carrier-based aircraft and *** above, and the aircraft carrier combat is in pairs (take care of each other, the aircraft carrier and fighters cannot move and fly when adding fuel), so the aircraft carrier is equivalent to a command platform, and the core technology is to command operations, tactics, So, although China has transformed an aircraft carrier (just a modification), it is still a long way from an aircraft carrier battle group.

The aircraft carrier is a monster that integrates all the core technologies of the air force and navy, such as the runway you said, it must be a perfect combination of hardness and toughness, too hard will break, too tough will deform, but also resistant to aircraft tail flame roasting, but also resistant to seawater corrosion, and this is just one of all technologies, the tip of the iceberg!

I personally understand that the core technology of aircraft carriers is the issue of carrier-based aircraft taking off and landing, and in order to master the technology of carrier-based aircraft take-off and landing, the Americans have had countless accidents, large and small, and several hundred aircraft carrier pilots have already lost their lives.

<> "Since some planes can take off and land vertically, why do aircraft carriers build such long runways?"

Aircraft VTOL is designed to deal with the lack of runway length, and if the runway is long enough, of course, it is better not to take off and land vertically.

It was the British who invented the technology of vertical take-off and landing of aircraft. In order to solve the problem of the aircraft carrier's drainage and small runway, they developed the "Harrier Wang Chi Pao" aircraft. Later, the Americans introduced the "Harrier" type, which was deployed on amphibious assault ships.

Vertical take-off and landing technology certainly solves the problem of using fixed-wing aircraft in a small space (otherwise you have to use ***, the first generation of aircraft carriers in the former Soviet Union is like this), but the disadvantages are obvious, that is, it seriously affects the take-off weight of the aircraft, that is, the aircraft can not carry enough ** and fuel, so that both the attack capability and the combat radius will be greatly reduced, if you want to cause air supremacy tasks, it is relatively reluctant.

Of course, for amphibious assault ships or small and medium-sized aircraft carriers, the use of vertical take-off and landing technology is a last resort when the take-off space is insufficient. It is also a way to take off by gliding, such as China's "Liaoning" ship. But there is also the same problem, which is the limited take-off weight.

As a heavy carrier-based aircraft, the J-15's excellent performance can only be fully exerted when a catapult is used.

Large aircraft carriers can use normal carrier-based aircraft, such as the American F A-18 Hornet, because the runway is long enough and the catapult is used to accelerate during takeoff. This kind of carrier-based aircraft taxied and accelerated on the runway like ordinary airplanes, because after all, it is impossible to have a runway of 2-3 kilometers like a land airport, and it is necessary to use a catapult to accelerate at the last moment of takeoff, and when landing, use a blocking cable to reduce speed to stop the high-speed aircraft. The advantage of catapult take-off is that the aircraft can take off at full load, so the combat radius is larger, it carries more ammunition, and is more capable of air supremacy and sea (ground) attacks.

At present, the United States' large nuclear-powered aircraft carriers use standard carrier-based aircraft and take off with runway catapults, while aircraft carriers of other countries, because they are medium-sized aircraft carriers, do not have the conditions to use runway catapults, so they adopt the method of gliding over and taking off; as for the vertical take-off and landing mode, the British "Harrier" type has been decommissioned, and the US F35B adopts short-range vertical take-off and landing because it is to be used on amphibious assault ships, and amphibious assault ships cannot carry ordinary carrier-based aircraft because the deck length is insufficient.

There are technical difficulties in the take-off of double-decker aircraft carriers: everything is unprecedented, everything is difficult at the beginning, and it is necessary to close the key to innovation and development, basically starting from a blank. The plan should be designed, and the technical materials should start from the reform, opening up, reform and innovation, and there should be a team, a relationship, and an overall plan, so as to seek the first spring.
