Chapter 742 Strange (First Update)

Liu Hai looked at the teacher's busy appearance and felt a little worried, because the shaftless water jet propulsion would be very difficult even by 2020.

There are many technical routes for shaftless propulsion, including magnetohydrodynamic propulsion, ramjet propulsion, sodium-water reaction water jet propulsion, and rim-driven propulsion.

According to some papers in 2020, the rim-driven technology route is currently the most mature and widely recognized direction.

This technology can solve the vibration and noise problems caused by the drive shaft in the traditional propulsion device to a certain extent and improve the stealth performance of the submarine.

When Liu Hai drew the picture for the teacher, he chose the direction that looked right in 2020.

However, whether this direction is correct or not, the teacher still needs to do further experiments and verify them one by one.

So now the model is just a preliminary beginning, and the later is the difficulty.

Of course, it is good to study some things in advance. The bald eagle also started research in this area after the millennium.

According to some information on the aircraft carrier, it can be determined that Fat Goose has an advantage in this regard.

To be honest, Fat Goose has strength in industry, machinery and military industry, especially in talent and technology.

Of course, the Big Black Fish of Fat Goose is the best in all aspects in 2020.

Of course, there is no way, because they don’t have enough money to get other equipment, but they have to ensure sufficient deterrence, so the Big Black Fish has become the only development direction.

In fact, to put it bluntly, why are Western countries not afraid of Fat Goose using mushroom eggs and the like.

Western countries are not afraid of Fat Goose’s mushroom eggs, because everyone has this thing, and there is no big difference between 1,000 and 10,000, because as long as it is used, basically everyone will throw it at each other.

There is also a dead hand system, which is actually just like that.

Of course, the shaftless water jet propulsion is not only used on the Big Black Fish, but also in many other places, especially in the civilian field.

The test site also looks messy, with various equipment and various lines.

Because the model needs to be run to comprehensively test noise, thrust, and various aspects.

"Engineer Liu, what performance do you think is most important for the Big Black Fish?" The deputy director in charge of military industry was on Liu Hai's right. Liu Hai originally wanted to put Sun Aiguo in the middle, but he didn't expect that the two directors would sandwich him in the middle.

"Speed ​​and noise. Low noise can avoid the enemy's search, and speed is the key to quickly escape after being discovered." Liu Hai spoke according to his own understanding.

"Then for the Big Black Fish, if this shaftless water jet propulsion is used, the most important thing is not the system that provides it with power?" The deputy director asked again.

Liu Hai nodded: "Yes, there is also the problem of its own power. The greater the power, the more problems there are. First of all, its own weight, and then the power supply. This is a systematic project."

"And the increase in its own weight and power will increase the noise, and the other is the material."

"It is very difficult to put this technology into practice in a short period of time."

Liu Hai also knew that our country has always attached great importance to the technology of the Big Black Fish, because we also know that if we want to fight against the fat bear and the huge military strength of the bald eagle, the Big Black Fish is an indispensable part.

Liu Hai also believes that in this time and space, our Big Black Fish technology is probably much better than the same period in history, but it is hard to say how good it is, because Liu Hai will not ask about such top-secret things, and the superiors will not leak them.

The deputy director in charge of military industry nodded when he heard this, and then talked about another thing: "Fat Bear's stealth fighter crashed again during the test."

"And this time it fell in a residential area. Bald Eagle and Niu Niu Fei Xiong's stealth fighters have never had such problems. What do you think is the fundamental reason?"

"It should be the electronic system." Liu Hai was not surprised at all, because Fei Xiong's fighter manufacturing concept is not compatible with stealth fighters at all.

Fei Xiong's design concept is that as long as the power is strong enough, the aircraft can be pushed into the sky.

However, the strange appearance of stealth fighters cannot fly at supersonic speeds, so no matter how strong the power is, it is useless. Too much power will make it more difficult to control the aircraft.

Liu Hai came from 2020, of course, he knows that this kind of aircraft design that uses appearance to be stealthy is a failed project, and the rest are all material stealth or coating stealth.

And because this stealth fighter wants to achieve stealth performance, the Bald Eagle is not even equipped with a fire control radar.

This thing also needs a special electronic warfare aircraft when it is in combat.

Of course, the Bald Eagle also learned a lot of experience from this stealth fighter, so the F22 came later.

Of course, when the F22 first came out, it amazed the world because its data was too good.

But from the perspective of 2020, the F22 is a short-legged and slow-speed aircraft.

But there is no way. When the F22 came out in history, it was the only stealth fighter in the world. It was awesome.

"I know that Mr. Liu has always been pessimistic about this stealth fighter. Can Mr. Liu tell me more about it?" The deputy director in charge of military industry actually wanted to ask this question for a long time, but he never had the chance.

There are also many people who want to know why Liu Hai is not optimistic?

"First of all, it is difficult for us to manufacture. Fat Bear is so powerful, but it has failed one after another, let alone us."

"In addition, this fighter itself has great shortcomings in speed and maneuverability due to its unique appearance and structure."

"The unique structure means increased control difficulty. It can be seen from the successive failures of Fat Bear that if the electronic assisted driving technology is not up to standard, this aircraft will be a coffin."

"In addition, the structure and unique performance of this aircraft itself are not suitable for installing fire control radar, which means that this aircraft needs other aircraft to guide it."

"The reason why Bald Eagle can succeed is that they have electronic aircraft and early warning aircraft that can guide this aircraft."

"I also designed it after seeing the papers of relevant experts of Fat Bear, but later I found that this still has many shortcomings. I think the direction of future stealth fighters should be coating stealth or material stealth, that is, there are special coatings that can absorb radar waves or materials." Liu Hai said so many things in one breath.

The deputy director in charge of military industry nodded. Fei Xiong's series of failures did illustrate the problem. Although our industrial strength is growing rapidly, there is still a big gap compared to Fei Xiong.

Even Fei Xiong has suffered heavy losses due to successive failures, let alone ourselves.

"So has Mr. Liu done any research on the stealth of coatings and materials?" the deputy director in charge of military industry asked again.

"There is no clue in this regard for the time being!" Liu Hai shook his head.

In fact, Liu Hai really knows a lot about stealth, because if you don't understand what stealth is, what kind of fighter jets are you making in 2020.

Besides, the f35 is ready in the aircraft carrier space. Although we don't know what the specific formula of its stealth material is, it's not a big problem to get a piece of it and do research directly.

But there is no time to do this now. After the fighter jet project at hand is completed, the next step is to make stealth materials.

There are so many materials on the f35 fighter jets, and you can waste your research. If you can't find any results, Liu Hai is not worthy of making fighter jets.

If we can get even a tiny piece of the f35 in 2020, it will be of great help to us.

Of course, our stealth technology is also very powerful. Anyway, in 2020, there are only two countries in the world that have stealth fighters, which can be regarded as real stealth fighters.

As for all other countries, Liu Hai thinks that only Fei Goose is worth looking at, and the rest are a joke.

At this point, Liu Hai suddenly had an idea and asked, "I wonder if Fei Xiong has any other fighter-related research projects?"

"It seems that there is no such thing. Xiao Liu, you also know that their leader is a bit ambitious. At the beginning, there was only one fighter research institute working on this stealth fighter. Later, the stealth fighters of Niu Niu and Gaul Chicken made their first successful flights, so all their research institutes came to work on this."

"But recently there seems to be a rumor that they have failed one after another in this project, and it seems that they are preparing to work on a new fighter project."

"But their leader obviously can't swallow this breath, so he is still investing." The deputy director in charge of military industry explained.

"Will the Su-27 project be lost?" Liu Hai muttered to himself when he heard this.

But it is possible, because the leader of Feixiong is really proud. The idea of ​​stealth was originally proposed by scientists in his own country. Can't his own country do it?

Niu Niu and Gaul Chicken have done it, but we can't do it ourselves. How embarrassed I am.

Besides, stealth fighter is such a high-end thing. Don't I, Feixiong, deserve to have such a high-end thing?

"Don't let Feixiong come out later than us in the future. This will be a bit good." Liu Hai thinks this possibility is very high. After realizing the various troubles of stealth fighter, Feixiong is likely to make a new fighter again in order to cope with the international situation.

The deputy director in charge of military industry has always suspected that Comrade Liu Hai's purpose of taking out the stealth fighter design seems to be a bit impure.

But there is no conclusive evidence now, but judging from the successive failures of Feixiong, this project is not a good project.

As for the stealth fighter projects of countries such as Niu Niu and Gaul Chicken, it is difficult for outsiders to know.

But if Comrade Liu Hai is not optimistic about the project, then there is a high probability that the project has problems.

Because according to Comrade Liu Hai's intelligence, it is impossible to give such a good project to others, and Comrade Liu Hai does not recommend it if we want to do it ourselves.

Whether Comrade Liu Hai is smart or not, you can tell by looking at the novels he wrote. Even an unintelligent person can write these novels.

"Does Mr. Liu think that the development of electronic systems in the future will be integrated circuits or electron tubes?" The deputy director in charge of military industry asked again.

"I personally think it should be integrated circuits, although in the current world situation, integrated circuits will suffer great losses when encountering emergencies."

"But now everyone has mushroom eggs, and the possibility of throwing mushrooms at each other is very small."

"Of course, this is just my personal opinion."

The deputy director in charge of military industry nodded when he heard Liu Hai's words, because he had long known that Liu Hai had invested a lot in semiconductors and integrated circuits, which could be said to be the largest investment project in the world.

The deputy director in charge of military industry is looking forward to how much impact Liu Hai's national fiber optic network will have on the world once it is put into operation.

Sun Aiguo heard this and asked: "I also understand some of the advantages of fiber optic networks, so can fiber optics be used on fighter jets?"

Liu Hai nodded when he heard this: "Fiber optic transmission has excellent anti-interference ability and will have a wide range of applications in the future. It is a general trend to use fiber optics in aircraft control systems in the future, but the application of fiber optics is not very mature now. In addition, a series of optical signal equipment are now relatively bulky."

The helicopters on Liu Hai's aircraft carrier space use fiber optic transmission, and the F35, F18, Growler, and Silent electronic warfare aircraft all use fiber optic transmission.

"That's good." Sun Aiguo nodded when he heard this.

The three of them chatted while watching Zhu Haiyang do experiments. Seeing the successful operation of the shaftless water jet propulsion, Liu Hai and the two factory directors applauded.

Successful operation is only the first step, and subsequent tests must be carried out in different environments, because there are various environments, seawater temperatures, and seawater pressures in the ocean.

"Congratulations, Mr. Zhu!" After the first test of the model, Sun Aiguo and the deputy director in charge of military industry congratulated Zhu Haiyang.

"This is the effort of all our researchers. We have just seen a door, and we haven't even entered yet." Zhu Haiyang was very happy.

"Teacher, you are already far ahead of the world at this step." Liu Hai also said with a smile.

"Yes, thank you for the hard work of our researchers." Zhu Haiyang certainly knew that no one abroad had studied this field.

After the test, Sun Aiguo gave a brief speech to the researchers, which was to encourage everyone to make persistent efforts. In addition, in order to celebrate the phased results, he gave everyone benefits.

The deputy director in charge of military industry also said a few words to everyone, and then everyone dispersed.

"Xiao Liu, I will go to Hainan with you this summer to meet the old leader." After leaving Zhu Haiyang's laboratory, Sun Aiguo got into Liu Hai's car.

"Yeah!" Liu Hai nodded. The old director will retire in a few years. People at his level are not afraid of others talking about him.

"We have received some news that Gallic Chicken has sold anti-ship missiles to some South American countries, and this news was given to us by a dealer." Sun Aiguo's words surprised Liu Hai.

"What does dealer mean?" Liu Hai asked in confusion.
