Therefore, as soon as Professor Li opened his mouth, he said: "I can only talk about the question of how to develop China's aircraft carriers, based on my personal opinion!"
At present, there are three main types of aircraft carriers in the world, according to the take-off mode of carrier-based aircraft, one is catapult take-off, one is glide take-off, and the other is vertical take-off.
If it is divided by power, there are three kinds, which are steam power, diesel power and nuclear power.
The Varyag is a steam-powered skid take-off aircraft carrier, but of course technically it does seem backward. ” After a pause, Professor Li added: "Our country has never built an aircraft carrier, so technically speaking, we may have to build our first aircraft carrier by borrowing the design of the Varyag aircraft carrier, and after gaining experience, we can gradually improve it to realize the construction of a catapult take-off aircraft carrier." ” The host said with a smile: "Professor Li said it very well, it is true that an aircraft carrier is a complex system project, and there are only a handful of countries in the world that can build aircraft carriers, so it is understandable if our country learns from the design of the Varyag."
For the construction of aircraft carriers, I would like to ask our ship expert Shen Gong to interpret how difficult it is to build aircraft carriers. ” Finally it was Shen Huan's turn, and Shen Huan did not panic at this time, he was already ready.
Shen Huan nodded and said, "The host is too right, the aircraft carrier project is a huge system project.
From the perspective of the industries involved in the construction of aircraft carriers, it includes manufacturers in high-end equipment manufacturing, aviation weapon systems, power systems, high-end materials and information systems.
For example, the steel used in the construction of aircraft carriers, a variety of special steel, which is the key to the construction of aircraft carriers, if China wants to build aircraft carriers, it will put forward extremely high requirements for our shipbuilding industry capacity and equipment technology level, and will also put forward extraordinary requirements for aviation, power, machinery, electronics, and materials. ” After a pause, Shen Huan continued: "Take aircraft carrier steel as an example, only four countries in the world can develop and produce aircraft carrier steel, Ah San in order to build his own aircraft carrier, according to the news, will import hundreds of tons of special steel from Damao, and to build a medium-sized aircraft carrier, about 20,000 tons of special steel is needed, so our country wants to build an aircraft carrier, the first problem to be solved is to develop special steel for aircraft carriers, because this kind of steel cannot be bought." ” "Of course, we have basically the infrastructure to build aircraft carriers, whether it is Dalian Shipyard or Jiangnan Changxing Shipbuilding Base, we have the conditions for building aircraft carriers, we have 300,000-ton docks, and there are also 1,000-ton gantry cranes needed for aircraft carrier construction, but many equipment on the aircraft carrier still need to be broken through one by one.
For example, the blocking cable used for aircraft carriers is currently only manufactured by Mi Guo and Da Mao.
This kind of arresting cable is required to be very strong, because a carrier-based fighter with a small 20-ton and a large 40-ton aircraft lands at a speed of more than 200 kilometers per hour, and this impact is very large, and a blocking cable costs several million dollars, and we cannot buy it, so we can only develop it ourselves.
Shen Huan said the truth, and even Professor Zhang nodded frequently when he heard it.
Shen Huan said: "Of course, the industrial chain formed by the construction of aircraft carriers also has a huge role in promoting the economic development of our country.
Therefore, I believe that although it is difficult to build a modern aircraft carrier, it will play a huge role in China's national defense construction and economic construction, and as long as the time is right, we should strive to build our own aircraft carriers!
” The host smiled: "After listening to Shen Gong's introduction, I was immediately excited, I know that Professor Zhang is an old navy, and Professor Zhang is also an aircraft carrier expert, so I would like to ask Professor Zhang a question on behalf of the majority of military fans, that is, if our country builds aircraft carriers in the future, how to solve the problem of carrier-based aircraft?"
” Professor Zhang laughed and said: "That's right, this question is indeed very tricky, I have been on the Varyag, and I have also been on the Melbourne and other aircraft carriers.
Without carrier-based aircraft, the aircraft carrier is an empty shell, a floating coffin at sea.
The combat effectiveness of aircraft carriers is realized entirely by carrier-based aircraft.
Speaking of carrier-based aircraft, it is impossible not to mention carrier-based early warning aircraft, without which the power of aircraft carriers will be greatly reduced, and carrier-based early warning aircraft, in general, can only catapult and take off.
So I think that in the future, if our country decides to develop aircraft carriers, it must take this into account.
That is, aircraft carriers that catapult and take off should be developed.
Da Mao's use of catapult to take off is also a last resort, because they can't develop a catapult system, and only the United States can engage in a catapult system in the world, and even the French buy catapults from the United States. ” "At present, the catapult take-off has developed a new electromagnetic catapult, of course, it has not yet been put into application, but is only in the exploration stage.
Steam catapult is still relatively reliable at present, and it is also a technology that we cannot cross in the development of aircraft carriers.
The principle of the steam catapult is to use high-pressure steam to push the piston to drive the slider on the ejection track and project the carrier-based aircraft attached to it.
In the seventies, the woolly bear experts encountered great difficulties in the development of steam catapults, and finally had to give up and adopt the technology of glide jump take-off and vertical take-off and landing.
But the shortcomings of the glide jump take-off are also obvious, that is, the carrier-based fighter can not take off with a full load, the combat capability is greatly affected, and at the same time, the carrier-based fixed-wing early warning aircraft can not take off from the deck, although the hairy bear uses the carrier-based early warning helicopter to solve this problem, but the performance of the carrier-based early warning helicopter can not meet the requirements, just a dispensable comfort.
Therefore, if we want to develop aircraft carriers, we must develop carrier-based fighters and carrier-based early warning aircraft, and we must also engage in catapult.
Professor Zhang said.
In fact, Professor Zhang didn't know that China had brought back two prototypes of the Su 33 a few years ago, which was all due to Shen Huan.
And the Varyag is in good condition, the power system is intact, the yield and corrosion resistance of the aircraft carrier deck steel are very good, not only strong but also non-magnetic, it has taken more than ten years from construction to transportation back to China, but its magnetic force is still zero.
Now not only the Varyag is being prepared for transformation, but also domestic carrier-based fighters based on the prototype of the J-11 and Su-33 are also being designed.
The design of the J-15 carrier-based fighter in 601 is basically borrowed from the prototype of the Su-33, and many of them are borrowed, for example, the overall layout and structure are the same, including the arresting hook and landing gear fenders.
The advantage of this is that the fighter can be designed as quickly as possible, and the test flight can be completed in the shortest time.
There are also many disadvantages, such as the problem of flight control, as well as the problem of innovation.
