Courtyard light

Chapter 645: Business Stealers Are Coming (Second Update)

In the afternoon, when Liu Hai got off work, he went to his father-in-law's former courtyard house.

In the winter, Liu Hai would come to check on me every now and then, mainly because he was worried that the water pipes and other things inside would freeze.

Heating was reinstalled in the courtyard, and water supply and drainage and flushing toilets were installed.

Liu Hai also built a glass greenhouse in the yard, which is of course heated by radiators. Liu Hai also planted some green plants in it, mainly vegetables, such as leeks, garlic sprouts, fennel, green onions and other lazy green plants.

The entire street has been dug up again and the sewers have been rebuilt. Anyone who has the conditions and is willing to change the toilets can do so. Of course, there is nothing that can be done for those who are not willing to change the toilets.

After looking around, there was no problem. The heating was very hot and the running water was no problem.

In one week, Dabao and Erbao will come back, and they will live here then.

Then he returned to the Siheyuan. Liu Hai was recently studying carrier-based early warning aircraft.

The main thing is to look at the various system components of this early warning aircraft. There is no possibility of copying this early warning aircraft.

Although it is also a ship-based early warning aircraft, the gap between the semiconductor-level early warning aircraft in the 70s and the early warning aircraft when Liu Hai crossed over is too big.

Bangs can only learn its overall structural layout and overall system composition.

The most critical thing for an early warning aircraft is the program. It must successfully select suspicious targets from the radar reflection waves of the early warning aircraft and lock on to the target. It must also screen out the most threatening targets based on the speed and altitude of the target and other unique radar characteristics.

It's better against the air, but it's more troublesome for the radar to filter the characteristics of ground reflectors.

The performance of radar depends on the level of its hardware, that is, the antenna and the chip.

In addition, the algorithm is also very important. The algorithm involves screening the threat level priority of the target, the response speed, and the recognition speed.

Algorithms can only be built on the most basic framework, and then optimized through continuous testing.

Moreover, different hardware matching algorithms are also different. The structure of the radar antenna, the structure and overall performance of the radar antenna are different, and the algorithms are also different.

Of course, the framework structure of the algorithm is the same, but the optimization data is different.

Liu Hai can only say that he is just building a shelf, because the entire system is too complicated. From design to manufacturing to operation, and then to continuous optimization of data and algorithms, Liu Hai estimates that a large team may take close to 10 years. time.

Especially now that our country has a blank slate for early warning aircraft.

All Liu Hai has to do is put up a show. Even if Liu Hai puts up a show, the subsequent design, R&D, manufacturing, data optimization, etc., will probably take at least five or six years.

"Yunjiu is still a bit small as a platform for early warning aircraft."

"If we can acquire DC's aircraft engine technology, we can produce larger transport aircraft."

It's not that Liu Hai doesn't want to develop a turbofan engine with a large bypass ratio, but if Liu Hai wants to develop that thing himself, I'm afraid it will take several years or even 10 years to see if he can come up with a successful engine.

The large bypass ratio turbofan engine is completely different from the turboprop engine and the engine used in fighter jets.

Liu Hai acquired DC10 because his engine was a General Motors engine.

In 2020, the three largest aerospace engine manufacturing companies in the world are General Motors, Pratt & Whitney, and Rolls-Royce.

Among them, the bald eagle occupies two, and the cow occupies one.

These three companies have established thick patent barriers in the field of aero-engines. Coupled with the overbearing flight licenses and airworthiness certificate certifications in North America and Europe, any company that wants to make a difference in the field of aero-engines will be attracted by this huge interest group. Straight to pieces.

The main reason for purchasing the dc10 is to obtain the technical license from General Motors.

Nowadays, it is relatively easy for Fat Bear to obtain technology licenses. If Fat Bear fails, then there is no chance of getting it.

"Big head!" The early warning aircraft involves too many things, and the bangs look so big.

After looking at Liu Hai for three hours, I felt a little tired. I put away the notes I had made and then left the aircraft carrier space to rest.

I continued to go to work in the factory the next morning, and my junior brother came again early this morning.

After the summer vacation, the junior brother would come to Liu Hai every now and then. After finishing his homework, he would ask Liu Hai to give him the test paper for the exam.

After the test paper is over, he changes toys. After getting the toys, he disappears for two days, probably to show off with his friends.

At noon, I took my junior brother to eat in the cafeteria.

In the afternoon, I went out to eat with my junior brother and junior sister, and then went to see a movie together. This is how junior sister has been talking about going to the movies together every now and then.

Liu Hai didn't refuse. Sometimes Liu Hai wanted to point it out, but didn't know how to say it.

I had no experience watching a movie for the first time, so I bought a few bottles of drinks the second time. I didn’t expect this to be wrong, because after drinking drinks and sitting for a long time, I wanted to go to the toilet. Going to the toilet while watching a movie was troublesome.

The next few times I watched movies, I would buy some melon seeds or beef jerky. Eating these dried things would make it harder to go to the toilet.

What Liu Hai didn't know was when he and his junior sister were sitting together watching a movie.

Niuniu's dealers are anxious. Some countries in the East want to purchase the complete set of technologies for the DC10 aircraft, and the transfer amount is about US$4.5 million.

With such a huge sum of money, why are Niu Niu's dealers not anxious? But with US$4.5 million, Bald Eagle's company certainly cannot make a profit.

So the dealer personally went to some Eastern countries and brought a complete set of black materials about the DC10 aircraft, which still had many shortcomings.

After the dealer arrived, he negotiated with the superior department and found out that Mr. Jack wanted to buy it privately.

This is even worse. Mr. Jack’s money is all in the dealer’s bank, which means that the Bald Eagle wants to take US$4.5 million from its own bank. How is this possible?

So when Liu Hai and his junior sister finished watching the movie and returned to the maintenance department, Sun Aiguo came not long after.

"Xiao Liu, there are some things where men need to take the initiative. You can't expect a young girl to speak first." Sun Aiguo came to Liu Haizhu's place and took off his cotton-padded jacket after entering the door before speaking.

"Isn't the leader here for this matter? I just feel a little embarrassed to open my mouth." Liu Hai thought that Sun Aiguo came here at 10 o'clock in the evening for this matter. "I'm already twenty-five or six years old. It's so easy for someone like you, my junior sister, to find someone to get married to. Why have you not gotten married for so many years? You just need to make it clear now. If there is a misunderstanding, it won't be embarrassing for long."

"I'll stop talking about this matter here first. There is an urgent matter next."

"The superior department agreed to negotiate with Bald Eagle to transfer the complete set of DC10 aircraft technology. However, the dealer found out about this matter, so the dealer came to us in person and wanted to cooperate with us in aircraft manufacturing."

"The superior department said that you are willing to invest, and they would like to talk to you." Sun Aiguo finished in one breath.

"Huh?" Liu Hai didn't expect such a change, but Rolls-Royce's engine technology is indeed excellent.

Moreover, Rolls-Royce did not fare well after the 70s. After 71, it was split up due to bankruptcy and was finally reorganized under the leadership of the Niu Niu government.

After the split, it was divided into an aerospace engine company and an automotive engine company.

The Rolls-Royce aviation engine we usually talk about is actually Rolls-Royce Aero Engine Company. The two companies were separated after 73. Of course, Rolls-Royce was later acquired by BMW.

The logo of Rolls-Royce is the same as that of Rolls-Royce, except that Rolls-Royce is silver and Rolls-Royce is blue.

To be honest, Rolls-Royce's aero engines are no worse than General Pratt & Whitney.

Moreover, Rolls-Royce is not only involved in military fighter aircraft engines, but also in high-bypass-ratio air transport aircraft engines, and even in the power facilities of Big Black Fish.

More than 1300 Gulfstream luxury business jets use Rolls-Royce engines.

However, later in history, Rolls-Royce's civilian nuclear energy instrument company was acquired by Gallic Chicken Company.

The reason why Liu Hai thought of this company was because it has a very classic aviation engine, the RB211.

This is the world's first three-rotor engine, and it is precisely because of this engine that Rolls-Royce has grown from a small aero-engine manufacturer to one of the three giants.

"Can dealers be the masters of their country? It seems that their country doesn't have any large aircraft that they can sell?" Although Liu Hai was very willing in his heart, he must say this.

"The dealer wants to have a chance to talk?"

"Their country's aviation industry is not good. As for large passenger aircraft, they don't have them at all. The Gallic Chicken next door has an Airbus A300." Sun Aiguo now also knows the large aircraft of these countries well.

"In order for dealers to show sincerity, what can they offer in exchange? I purchased the dc10 mainly for their complete set of mature technologies, and the most important thing is the technical authorization of aero-engines."

"Because if our country designs and manufactures aero engines, it will inevitably infringe on their patents, because they have many patents in the field of aero engines, especially civil aero engines." Liu Hai said.

"The Dc10 complete set of production technology and mature process standards can indeed improve the quality of our country's aircraft manufacturing technology. As for the aero-engine patent you mentioned, this is also a headache."

"So what do you mean now?" Sun Aiguo could understand Liu Hai's words.

"We need to show their sincerity before we can talk. Now I'm just talking nonsense. After all, Bald Eagle has a full set of DC10 production technology and craftsmanship." Liu Hai said.

"I know what you mean, you just want to use the bald eagle to squeeze them. In fact, our goal is just Niu Niu's aero engine?" Sun Aiguo understood immediately.

"Well, that's it. My money is still in the dealer's bank anyway." Liu Hai nodded.

"That's fine."

"The various data of the dc10 brought by the dealer are not good. On the one hand, the fuel consumption is very high, and the failure rate is not low. The dealer said that the dc10 is an outdated product that has been eliminated." Sun Aiguo said again.

"Passenger transportation consumes a bit of fuel, but freight transportation is very efficient." Liu Hai nodded.

Sun Aiguo hurriedly went to report overnight.

After hearing the feedback, dealers were a little confused. What they were interested in was the overall manufacturing technology and overall manufacturing process of large aircraft, as well as complete processing equipment. What could they come up with?
So the dealer went back to Niuniu to take a look, and finally found that the only thing he could get was the aircraft engine.

The dealer set his sights on the empty A300 next door, but the dealer felt uncomfortable when he thought of letting the next door make money. Instead of letting the next door make money, it would be better to let the bald eagle make money.

Therefore, the dealer could not make up his mind for a while. A single aerospace engine would definitely not be able to compare with other people's complete set of large aircraft production technologies.

Liu Hai didn't expect that the dealer would come to interfere, but Liu Hai also knew that all his money was deposited in the dealer's bank at Niu Niu. The dealer would definitely not be willing to give such a large sum of money to Bald Eagle in vain.

The superior department is still continuing to communicate with Bald Eagle. Of course, this transaction must take a long time from communication to closing, because every condition needs to be considered repeatedly.

Liu Hai put this matter aside. Anyway, he can't rush these things. In international transactions, the more anxious you are, the more you will become a target for others to take advantage of.

The second Yinjiu has undergone rigorous factory testing and has been delivered, while the third prototype has begun final assembly.

After the Yunjiu aircraft is delivered, pilots will first be trained, and then more training such as airborne and airdrop training will be conducted.

The individual air defense missile and battery projects in Liu Haishou will not have results before the year.

"Finite element analysis software!" Liu Hai has always wanted to work on this project. The finite element method was originally used to calculate the structural strength of the aircraft.

By the time Liu Hai crossed, the finite element method had been widely used in almost all fields of science and technology because of its high efficiency, and was later integrated with CAD software.

Liu Hai uses this kind of design software on the aircraft carrier. Of course, Liu Hai's design software is the latest model in 70, and its functions are so powerful that all scientists in the s would not believe it.

Liu Hai was going to finish the things at hand and do this, using the supercomputer of Dongfang University to do it.

The supercomputer of Dongfang University was personally invested by Liu Hai, or it can be said that it was donated by Liu Hai.

The reason why Liu Hai did not come up with this software earlier was because we did not have the relevant talents at that time. The supercomputer in Dongfang University has been running for a year. Next year Liu Hai decided to put up this software framework.

Seeing that Dabao and Erbao were about to come back, Liu Hai decided to have a good talk with his junior sister.

Liu Hai felt that if he continued like this, he would be delaying his junior sister. After all, he was already twenty-five or six years old. It was the most beautiful season in life and he wanted his junior sister to recognize him clearly.

Liu Hai's own personal problems didn't matter. Anyway, he had a son and there was no shortage of women. If the superior department hadn't worried about him, Liu Hai would have never planned to get married again.
