Chapter 742 Strange (First Update)
Liu Hai looked at the busy teacher and felt a little worried, because it would be very difficult to develop a shaftless water jet propulsion system 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 paper materials in 2020, the rim-driven technology route is currently the most mature and widely recognized direction.

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

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 conduct further experiments and verify it one by one.

So now the model is just the initial beginning, the later part will be the difficult part.

Of course, it is beneficial to study some things in advance. Research on bald eagles only began after the millennium.

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

To be honest, Fei Goose does have strength in industry, machinery, and military industry, especially in terms of talent and technology.

Of course, Fat Goose's Big Black Fish is second to none in all aspects in 2020.

Of course, there is no other way, because they do not have enough money to buy other equipment, but they have to ensure sufficient deterrence, so the big black fish becomes the only development direction.

In fact, to put it bluntly, why are Western countries not afraid of fat geese using mushroom eggs and the like?

What Western countries are afraid of is not the fat goose's mushroom eggs, because everyone has them. There is no big difference between 1000 and 1 of them, because as long as they are used, basically everyone will throw them at each other.

There is also the dead hand system, which is actually just so-so.

Of course, shaftless waterjets are not only used on big black fish, but are also used in many other places, especially in the civilian field.

The test site also looks messy, with all kinds of equipment and lines.

Because the model needs to be run through comprehensive tests on noise, thrust, and various aspects.

"Engineer Liu, what performance of the big black fish do you think is the most important?" The deputy factory director in charge of military industry was on the right of Liu Hai. Originally, Liu Hai wanted to put Sun Aiguo in the middle, but he didn't expect that the two factory directors would sandwich him in the middle, one on the left and one on the right.

"Speed ​​and noise. Low noise can help you avoid enemy searches, while speed is the key to quickly escaping after being discovered." Liu Hai spoke according to his own understanding.

“So for Big Black Fish, if you use this shaftless water jet propulsion system, 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 issue of power itself. The greater the power, the more problems there are. First of all, there is the weight, and then there is the power supply. This is a systematic project."

"And the increase in weight and power will increase the noise, and the other issue 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 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, 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 to what extent, because on the one hand Liu Hai will not inquire about such top-secret things, and on the other hand the higher authorities will not leak them.

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

"And this time it landed in a residential area. The stealth fighters of Bald Eagle and Niuniu Feixiong have never had such problems. What do you think is the fundamental reason, Mr. Liu?"

"It should be the problem of the electronic system." Liu Hai was not surprised at all by this matter, because Fei Xiong's fighter jet manufacturing concept was simply incompatible with stealth fighter jets.

The design concept of Fat Bear is that as long as the power is strong enough, the plane can be pushed into the sky.

However, due to its strange appearance, the stealth fighter cannot fly at supersonic speed, so no matter how strong the power is, it will be useless. On the contrary, too much power will make it more difficult to control the aircraft.

Liu Hai has been here since 2020, and of course he knows that this kind of aircraft design that uses appearance to make it stealthy is a failed project. The rest are all about material stealth or paint stealth.

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

This thing needs special electronic warfare aircraft to be used in combat.

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

Of course, when the f22 first came out, it amazed the whole world because its data was so excellent.

However, looking at the F2020 from the perspective of 22, it is a little short-legged and slow.

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

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

Similarly, many people want to know why bangs are not popular?

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

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

"The unique structure means that the control difficulty increases. 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 doomed."

"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 to be guided by other aircraft."

"The reason why the Bald Eagle was able to succeed is because they had electronic aircraft and early warning aircraft that could guide the plane."

"I came up with the design after reading a paper by an expert on Fei Xiong, but later I found that it still had many shortcomings. I think the direction of future stealth fighters should be coating stealth or material stealth, that is, having special coatings or materials that can absorb radar waves." Liu Hai said so many things in one breath.

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

Even Fat Bear suffered heavy losses due to successive failures, let alone ourselves.

"So, has Engineer Liu done any research on invisible coatings and materials?" the deputy factory director in charge of military industry asked again. "I don't have any idea about this for now!" Liu Hai shook his head.

In fact, Liu Hai really knows a lot about stealth, because if you don’t understand what stealth is, then what’s the point of making fighter jets in 2020?

Besides, the F35 is already available in the aircraft carrier space. Although we don't know the specific formula of its stealth material, it shouldn't be a big problem to just get a piece and do research on it.

But we don’t have time to do this now. After completing the current fighter jet project, the next step will be to work on stealth materials.

There are so many materials on the F35 fighter jets, and Liu Hai can waste them all on research. If he can't produce any results, he will not be worthy of making fighter jets.

If we can get even a tiny piece of the f2020 in 35, it will be of great help to us.

Of course, our stealth technology is also very impressive. In 2020, there are only two countries in the world that have stealth fighters that can be considered true stealth fighters.

As for all other countries, in Liu Hai's opinion, only Fat Goose is worth looking at, the rest are a joke.

At this point, Liu Hai suddenly had an idea and asked, "Does Fei Xiong have 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, only one fighter research institute was working on this stealth fighter. Later, the stealth fighters of Niu Niu and Gaul Chicken successfully completed their maiden flights, so all their research institutes came to work on this."

"But there seems to be a rumor recently that they have suffered a series of failures in this project and seem to be preparing to start a new fighter jet project."

"But their leader obviously can't swallow this, so he's continuing to invest." The deputy factory director in charge of military industry explained.

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

But this is really possible, because the leader of this generation of Fat Bear is really concerned about his reputation. Originally, the idea of ​​invisibility was proposed by scientists in his own country. Can't his own country do it?

I feel so embarrassed that the Bull and the Gallic Rooster have both been developed, but we can’t do it ourselves.

Besides, stealth fighter jets are such high-end things. Don’t I, Fat Bear, deserve to own such a high-end thing?

"It would be nice if Fat Bear develops it later than us." Liu Hai felt that this was very likely. After realizing the various troubles of stealth fighters, Fat Bear would most likely develop a new fighter again in order to cope with the international situation.

The deputy factory director in charge of military industry has always been suspicious that Comrade Liu Hai's purpose in coming up with the design of the stealth fighter seemed to be a little impure.

But there is no conclusive evidence now. However, judging from the successive failures of Fat Bear, this project is not a good one either.

As for the stealth fighter projects of countries like China and France, it is difficult for outsiders to know.

However, if Comrade Liu Hai is not optimistic about a project, then there is a high probability that there is something wrong with that project.

Because given Comrade Liu Hai's intelligence, it is impossible for him to hand over such a good project to others. Moreover, even if we wanted to do it ourselves, Comrade Liu Hai would not recommend it.

To know whether Comrade Liu Hai is smart or not, just look at the novels he has written. Even a stupid person can write these novels.

"Mr. Liu, do you think the future development of electronic systems 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, so 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 what Liu Hai said, because he had long known that Liu Hai had invested huge amounts 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 seeing how much impact Liu Hai's national fiber optic network will have on the world once it is operational.

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

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

The helicopters on the Liu Hai aircraft carrier use fiber optic transmission, and the f35, f18, growler, and silenter 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 doing the experiment. Seeing the shaftless waterjet propulsion unit operate successfully, Liu Hai and the two factory managers applauded.

Successful operation is only the first step. Subsequent testing will be required in different environments because there are various environments, sea water temperatures, and sea water pressures in the ocean.

"Engineer Zhu, congratulations, congratulations!" After the first test of the model was completed, Sun Aiguo and the deputy factory director in charge of military industry congratulated Zhu Haiyang.

"This is the result of the efforts of all our researchers. We have just seen a door and haven't even entered yet." Zhu Haiyang looked very happy.

"Teacher, you are already far ahead of the world now." Liu Hai said with a smile.

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

After the test, Sun Aiguo gave a brief speech to the researchers, encouraging them to keep up the good work. In addition, he gave everyone benefits to celebrate the interim results.

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

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

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

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

"What does 'dealer' mean?" Liu Hai asked puzzledly.
