"It's a pity that it's all destroyed, otherwise, we will transplant this catapult to the ground, and maybe we can carry out the training of carrier-based aircraft." Qin Feng looked at the part where the cylinder of the catapult was slotted, and a hole had been blown out, and he felt extremely distressed.

As long as there is a little leakage, it can't be used, let alone now, this thing is almost impossible to repair, which means that this is all rags, and nothing can be done except to be able to disassemble and sell scrap metal.

"Not necessarily." At this moment, a voice came from behind him, an old man in good spirits, standing behind Qin Feng, behind, there were a few people, it seemed that they were all coming from the bridge, and at this time it was also dark, and they could only rely on the dim light on the port to see the people clearly.

Qin Feng still didn't know him, but Tu Lao and Song Lao both knew each other, and when they saw this old man, they immediately shouted: "Old Pan!" ”

There is a specialization in the art industry, the old Pan in front of him, is the leader in the field of warship construction, back then, it was he who led everyone, overcame all kinds of difficulties, and got the brigade-class destroyer, and now, I heard that the development of the second-generation destroyer is being carried out in China, and the old Pan in front of him is still the chief designer of the destroyer, and now, he, the best ship designer in the country, came over almost non-stop after getting the news that there is an aircraft carrier here, and they came earlier than Qin Feng and his party. I've been in the cabin for a long time, and now it's getting dark.

"What have you learned?" Song Lao asked.

"Although we can't put these equipment into use, but for the first time, we have also seen the structure of the catapult, the piston, the cylinder, how to combine, we have mastered the basic principle, let us open our eyes, but to say that this catapult, in fact, the most critical is not the processing of the cylinder, do you know what it is?"

In fact, the current Melbourne catapult is only an old-fashioned push rod low-power catapult, and the Americans' 100,000-ton supercarrier uses a C13B high-power catapult, which can no longer be regarded as the same thing, but many of the structures are the same.

How big the difficulty of the catapult is, just look at the French, who have a strong sense of national pride and came up with the aircraft carrier Charles de Gaulle, but the catapult of the aircraft carrier was not developed by itself, and it was bought from the United States at a high price, this thing is too difficult.

In addition to the cylinder, there is another important thing, and that is the gas tank!

Speaking of the principle of catapult, it is generally only said that the boiler boils water, and then the steam enters the cylinder, pushes the piston, and drives the aircraft forward, but there is another key point, that is, the steam is not directly transported from the pipeline, so that the pressure cannot be adjusted, let alone continuous ejection, nor can it meet the needs of power.

The steam coming from the pipeline first enters a gas storage tank, and then from the gas storage tank, it is directly delivered to the cylinder.

This gas tank is very simple, it is a spherical tank, but a simple tank is something that examines the industrial level of the whole country. The manufacture of this gas tank is no less difficult than that of the cylinder, and few countries have the ability to produce just the special steel material used to make the gas tank. This material should meet the good creep performance and tensile strength, but also have weight limitation and high temperature resistance, and the tank should also be able to withstand hundreds of thousands of fatigue cycles of pressurization and pressure relief, and the difficulty of manufacturing can be imagined.

This is a formation, it needs to be pressed out by a super powerful hydraulic press, these are blank in China, you know, this is still a light aircraft carrier, if it is a supergiant like an American aircraft carrier, what is needed is even more unimaginable.

In this way, a small gas tank can reflect the industrial level of a country.

It can be said that if China wants to build an aircraft carrier now, there are many technical difficulties, of course, there will definitely be difficulties, but if the higher authorities give an order, everyone will try their best, the Chinese nation has a long history of 5,000 years, has a prosperous and splendid civilization, and now in the new period, it will also re-enter the glory, and will definitely not bow down in the face of such a small difficulty.

It's just that this time it's really eye-opening.

"Let's go, we've been studying all day, let's go down to eat first, and we'll come back tomorrow." General Ma said.

When everyone heard General Ma say this, they felt that their stomachs were indeed hungry, yes, people are iron, rice is steel, you should eat first!

Of course, even if it is a meal, everyone is inseparable from the topic in front of them, the comrades of the shipbuilding sat together, discussing excitedly, what they said was very professional, so that Qin Feng was very interested in listening, although there were professionals who did not understand very well, but they were definitely very powerful.

"Their bridge is not big, many sailors sleep on the lower deck, it is not easy to ensure a good sleep, the ventilation system of the entire ship is quite critical, but unfortunately in several places, it has been destroyed."

"The hangar is specially designed for a certain kind of fighter, and when this aircraft carrier is being developed, it really has to choose a good carrier-based aircraft."

When they said that the carrier-based plane came up, Qin Feng was finally able to interject and said to the other party: "So, can our current Jian-7 get on the ship?" ”

"Of course not, there are many requirements for carrier-based aircraft, the wings have to be folded, the landing gear has to be strengthened, and the take-off and landing speed has to be low, all of which the J-7 is not satisfied."

"Yes, it's enough, but our Jian-7 CP is definitely okay." Qin Feng said: "Do you know our Jian-7 CP? ”

Before Tu Lao could interject, Qin Feng had already begun to sell the Jianqi CP to the navy, and there were several naval generals present, who were also very interested when they heard Qin Feng say this.

At this time, a voice came from outside again: "It's late, it's late, I'm going to see what I say today." ”

Hearing this voice, Qin Feng was immediately overjoyed, it was Mr. Gu who came!

In addition to Song Lao and Tu Lao, fighter experts from the north also arrived, but unfortunately they came late, so they didn't take a fancy to it today.

After coming in, Mr. Gu heard Qin Feng's words, and now, sitting on the stool, he immediately said: "If you want to talk about this ship, I think our J-13 project is just right." ”

J-13? Why did you take out the J-13 again?
