Liu Hai had to clear himself, because Liu Hai estimated that the higher authorities might also set up a special unit to study this thing.

Bangs can't say that this thing is a pit, you don't have to study it in the higher departments.

Of course, the pit is not a complete pit, if it is just a study, then it will still be of some help to the design of stealth aircraft in the future.

Therefore, in the technical information submitted last time, Liu Hai specifically mentioned his own technology, which was designed according to a paper by a scientist in Fat Bear.

The theory of stealth technology was first developed in 1964 when the fat bear mathematician Ufimochev proved in a paper that the intensity of an object's reflection to radar is related to its edge configuration rather than its size.

He proposed a method for calculating the radar cross-sectional area (RCS) of the surface and edges of an object, which supported the design of aircraft with low RCS.

In the 1970s, analysts at Bald Eagle Lockheed discovered Ufimochev's thesis and, using computers and software that were already well developed at that time, began research and development of stealth aircraft.

As for whether the higher-level departments will hand over the technical information to Niu Niu and Gallic chickens, Liu Hai estimates that it is impossible.

"Of course this one is for sure, there are so many scientists and so many departments in their country, they will definitely not say what we give, they will do it, and after the last time, it took half a month to reply to us."

"It's definitely going to validate the design." Sun Aiguo thought that Liu Hai was modest, so he spoke.

The mainstream of stealth aircraft is still stealth paint in the end, not design, look at the stealth aircraft designed by several countries in the back.

"I'm very busy right now, and the Y-9 aircraft is ready to start assembling this year, and strive to come up with the first prototype before the end of the year."

"There are also a few cartoons, mainly because the character models at the beginning of these two cartoons need to be handled by myself."

"No matter how high their design fees are, they don't make any money from these two cartoons." Liu Hai also knew that the higher authorities probably wanted to design this aircraft themselves.

But how is it possible, this is a sinkhole, and now it is already a great deal to come up with a theory and a shape design, if you give them a design again, and then they fall into the pit, do you think they will complain about themselves at that time?

Liu Hai knew that the cost of this plane was $130 million, and Bald Eagle built a total of 59 of them, of course, the real cost is said to be only about $49 million.

This is one thing, and the other side is that the current stealth direction is wrong, that is, spending billions of dollars in the wrong direction, this is not to mention for the time being, the key is to delay time.

In the past, when the Bald Eagle family was in the past, he might have only built 59 planes, but when Niu Niu and Gallic chickens and fat bears were all made, could he have made such a small number?

So this pit is very big, and the bangs don't dare to mix it anymore, although the bangs also want to show that they take out the design of 117, but there are too many things involved.

The bangs are at most to take out the body structure, as for the flight control assistance system inside, as well as the engine, the bangs can't do it.

"You're really busy right now!" Sun Aiguo also knows how busy Liu Hai is now.

Of course, Sun Aiguo also knows how long it will take to design such an aircraft, especially Liu Hai has not studied turbofan engines much.

And Sun Aiguo also calculated the two cartoons in Liu Hai Lane from the other side, maybe it will bring hundreds of millions of dollars in income, and the other party will definitely not give so much for the design fee, and the cartoon is a long-term income.

"Niu Niu and Gallic Chicken decided to start research on two aircraft at the same time, one is a new stealth fighter, and the other is a carrier-based aircraft project." Sun Aiguo spoke again.

Liu Hai nodded, the military equipment manufacturing strength of these two countries in this era is still very considerable.

In any case, it will be good for us to let these two countries stand together now.

As Europe in the middle, once it is supported, then the fat bear and the bald eagle will also be supported, which will increase the competition between military equipment.

It can consume the strength of these countries more quickly, just like when playing a game, we are now secretly developing and letting others go to the line.

"The barren land you mentioned last time, their country has begun to be chaotic, according to the news we have got, the main thing is the fat bear and the bald eagle, and the two forces are behind."

"They all want to prop up their own regimes to come to power, and it seems that this place is destined for chaos." Sun Aiguo talked about another thing.

"Hmm!" Bangs nodded.

"And Xiaoyun may come back in early June." Sun Aiguo looked at the bangs.

"Actually, she wouldn't have had anything to do if she came back two years earlier, but they have their own worries, after all, your father-in-law has experienced these things before." Sun Aiguo also knew that Xiaoyun and his family were worth worrying about, and he would be worried if he changed himself, after all, after earning so much money, who knows what he will face when he comes back.

"Come back, come back!" Liu Hai also knows his father-in-law's worries, he is delicate and expensive, and he will worry about anyone else, and he probably plans to come back when he sees the situation getting better and better.

And Liu Hai can't tell Xiaoyun about many things in China, after all, many of the projects Liu Hai participates in are highly confidential projects, and the superior department will definitely not tell Xiaoyun everything as it is, and Liu Hai can't say it, even if he says it, Xiaoyun won't know, because in the past few years, Liu Hai's letters will be reviewed by the higher departments, and the content of the letter must be copied again.

Xiaoyun's reply to the letter will also be checked by the higher authorities, and the main reason for copying is that some people are afraid that some people will do tricks in the letter.

Therefore, Liu Hai writes letters very often, because he knows that someone wants to read the letter he wrote and has to copy it, and some things are embarrassed to write it.

"You have a number in your own heart, and I won't talk about many things." Sun Aiguo mentioned it again.

Of course, Liu Hai knew that it was okay for Xiaoyun to come back as Sun Aiguo said, but if he wanted to remarry, Xiaoyun would definitely not be able to interact frequently with those people abroad, and the higher authorities would definitely be worried.

I am afraid that my good seedlings with red seedlings will be led astray by Xiaoyun.

Of course, Liu Hai can't say that he has also experienced capitalist life, and that's it.

And to be honest, our people are generally looked down upon abroad, after all, they are countrymen, and they will be looked down upon when they go to the city, not to mention that people from your country run to other countries, and it makes sense for people from other countries to look down on you.

"Now the higher authorities are conducting several rounds of negotiations with Western countries, mainly on the issue of import and export, tax rate, and other issues."

"In addition, the higher-level departments have also set up a lot of technical training courses in remote cities and counties according to Ling's suggestion."

"There are so many issues involved, first of all, the issue of wages." Sun Aiguo spoke again.

"It is necessary to guarantee the working hours of the workers, as well as the intensity of the work, as well as the wages of the workers." Liu Hai opened his mouth and said, we now have a lot of advantageous industries in China, so there is no need to engage in any low-end manufacturing.

Because low-end manufacturing does not have enough profit margins and technical reserves, it has only been reduced to a cheap labor market.

And now the development of the entire industrial chain of our automobile industry can be said to have reached the world's first-class level.

"This is natural, the higher authorities will legislate." Sun Aiguo nodded.

"And what you suggested last time, spending money on people over 60 years old in rural areas and those who have lost their labor force, has been discussed and approved by the higher authorities, but the specific amount of money is still being discussed."

"Because the next step is to increase wages, and then gradually open up in some areas that are not so critical, so now many local small traders and hawkers, as long as they are not blatant, basically no one cares." Sun Aiguo spoke again.

In fact, Liu Hai thinks that Bald Eagle is a planned economy, and we should still learn from it.

Many people mistakenly think that Bald Eagle is all market economy, which is a big mistake.

Let's talk about a simple example, that is, the bald eagle, there are many associations in the country, take a simple animal husbandry association as an example.

They will stipulate how many cattle or sheep you have on your farm, and if you don't have a pig quota on your farm, you don't want to enter the market if you raise a lot of pigs privately, and you will be fined, of course, you can raise a few of them yourself.

There is a cap on the number of animals farmed on each farm, and if you want to change the type of animal you are farming, then you need to apply for it, and then the animal husbandry association will approve the change.

It's the same with agriculture, where you can grow soybeans, corn or forage, and you have already submitted a plan in the first year.

They don't go into detail, they plan to everyone and they just plan the land, that is, what to do and what can be done on the land.

No matter how the owner of this land changes, his plans for this land will not change.

It will not be like a group of people in some places who go to the countryside to catch dogs and chickens.

There are also bullshit experts who have never done farm work and then use their imagination to write articles, and the key is that they are executed.

Of course, such things are happening in the West.

Bangs nodded, grasping the big and letting go of the small, this is inevitable, because if it is too small, the cost of manpower management will increase.

Because some departments have said that it is true, the work that can be done by one person may be more than ten people after being allocated.

When Liu Hai and Sun Aiguo were talking about things, Fat Bear also announced the launch of the stealth fighter project, and also announced the launch of the stealth bomber project.

And Fat Bear also announced in a high-profile manner that he had a preliminary design plan, and then published the appearance of the 117 aircraft in the newspaper, and Fat Bear said that he had been involved in the stealth project more than ten years ago.

Also took out the 1964 paper of the mathematician Ufimochev.

This time, the bald eagle was not good, and began to increase efforts to thoroughly investigate all the people of the 117 project.

This led to the temporary suspension of Project 117, and everyone was under suspicion until a thorough investigation was completed.

Some departments of Bald Eagle are even more nervous, and they are suspicious when they look at their colleagues anyway.

The main thing is that the succession of things is too weird, and the last Greyhound incident was investigated for a long time, and in the end there were no problems.

Although everyone does not believe in this result, this is the result.

Now there is such a thing, and the origin of the technology of Niu Niu and Gallic chickens is mysterious.

Of course, no one suspected a certain big country in the East in this matter, and Bald Eagle suspected that it was someone from his own family, especially everyone involved in the 117 project.

Bald eagles, cow cow Gallic chickens, and fat bears started competing in stealth events.

I have to say that the paper data of 117 is quite good, even without the stealth coating.

But who would have thought that such a good aircraft with good data on paper would collapse in the end in actual combat, and then all of them would be retired in a few years, but it seems that when the bangs crossed, Bald Eagle was ready to convert all these retired aircraft into UAVs.

In the face of this round of the international arms race, no country can intervene, this thing is too high-tech, and many countries can't even figure out the theory, let alone design and manufacture.

Of course, what Liu Hai didn't know was that the higher-level departments also organized a special department to study the project.

Liu Hai is now very busy every day, mainly on the various designs of the Yun-9 aircraft.

The design of the main engine room wing is completed, but the design of various internal systems is also dazzling, such as hydraulic system, circuit system, fuel system, sealing system, cargo system, anti-icing system and so on.

Liu Hai himself still has to design the turboprop engine, and directly throws out the parts drawings one by one, and then doesn't care, and then just accepts the parts.

In addition, you will have to conceive a character model for Toy Story and the Gundam animated movie.

However, these two cartoons are not in a hurry, because these two cartoon dealers are preparing to use next summer vacation to impact the summer file.

In the future, Christmas will be Kung Fu Panda and Transformers, and the summer file will be Toy Story and Gundam.

In other words, dealers should put all the two most important movie schedules in the West on animated films.

As for personal matters, bangs are now focusing on a casual fate, mainly because they are too busy, but fortunately, there is space for aircraft carriers to accomplish many other things, otherwise, the various progress of bangs is not so fast.

The construction of Liu Hai's personal museum has begun, Liu Hai personally designed the 5-storey height, of course, this floor height is relatively high, and a three-story parking lot has been built below, which is expected to be completed before the arrival of this winter.

That is, these 50 acres of land, at least 45 acres below are parking lots, and parking fees can be received in the future.

Finally in late May 1977, Liu Hai received the news that Xiaoyun was coming back, and in mid-June, this time Xiaoyun and the two children came back, and the old man did not come back, so Liu Hai found someone to clean up the yard where the old man lived before.

The yard where the old man used to live was always said to Liu Hai, but Liu Hai never asked for it, and the higher authorities did not take the house away, so it has been in a vacant state, and Liu Hai waited for Xiaoyun to come back this time to transfer the house to Xiaoyun and them.
