Reborn Xiangjiang Tycoon Growth

Seeing Bao Zixuan sitting next to him, Old William immediately had an idea. If he could get something out of this guy, McDonnell Douglas would not suffer a loss even if the two companies did not cooperate in the future.

Bao Zixuan has such a clear understanding of the fourth-generation fighter jets. If Heiyun has not carried out relevant research and development, it will definitely not be convincing. McDonnell Douglas is still in the theoretical stage of the fourth-generation fighter jets and has obtained some experience from Heiyun.

Ideas and suggestions will definitely give you an advantage in the future research and development process.

At least there would be no disadvantage in communicating with this kind of person, and old William did not continue to drink. Firstly, he was older, and secondly, he knew how much he drank. Although he did not have much contact with Bao Zixuan, he also knew that this boy had an amazing drinking capacity.

.

William Wales Douglas smiled and said: "How about we design a fourth-generation machine together here, just as a kind of entertainment."

What does old William mean? He drank too much, but he doesn’t look like it!

In fact, old William was not drunk at all at this time and was still very sober. At such an old age, drinking would not cause trouble. That was what young people did.

I just heard Bao Zixuan's definition of the fourth-generation fighter jet, and the previous drunkenness disappeared instantly. This is a good opportunity. Old William is very cunning. Just hearing the definition is not enough. He must see the Heiyun fourth-generation fighter jet.

shape.

Fighters are different from civilian aircraft. It is impossible for McDonnell Douglas to cooperate with Heiyun. First of all, the Ministry of Defense will not agree. It must be independently developed and the core technology cannot be mastered by companies outside the United States. Then the problem is that there is no relevant technology reserve yet.

What should I do? Do I have to start from scratch?

That would not only waste a lot of time, but most importantly, you would have no way to start. There was no concept before, and everything needed to be tested continuously.

If we can dig out a little more from Heiyun Group and Bao Zixuan, we will definitely be able to design fourth-generation fighter jets in the future. Although the motivation is not pure, as long as we can get results, who cares about anything else!

Bao Zixuan: "Since Senior William is so interested, let's treat it as a kind of entertainment."

"Use a computer or draw by hand, it's up to you."

Hearing Bao Zixuan talk about using computers, William Wales Douglas felt very curious. Could it be that computers can be used to design aircraft sketches? Today I will test it.

Old William: "I can do hand-drawing, but I still want to try new things; can the computer meet the requirements?"

Old people who have been engaged in aircraft research and development during World War II still believe more in tradition.

Bao Zixuan said with a smile: "As long as senior William wants to express anything, the computer can do it. Of course it is limited to design drawings, but it may not be able to do other aspects."

Hearing that computers could do so many tasks, old William immediately became interested. So he smiled and said, "Then try it with a computer and see if it's as magical as you said."

Bao Zixuan made a gesture, and the bodyguard immediately took out the laptop.

Before the staff could take action, Debbie Dickinson immediately took action. She cleared the table so that Bao Zixuan could put his laptop on it.

Both men looked at the woman who was just serving her and didn't say a word. Bao Zixuan didn't expect that a model could do this. It seemed that he had really underestimated the beauty in front of him before.

After turning on the computer, Bao Shaofu clicked a few times. A fighter jet model appeared. Although it was just a sketch, the outline was already very clear.

This made Debbie Dickinson feel amazing, not only as a beautiful model, but also as a professional, old William found it incredible. It turns out that computers can design airplanes so quickly, and it took him half an hour to draw this sketch alone. It seems that

Many ideas need to be changed, otherwise we will never be able to keep up with the development of Heiyun.

By then, let alone surpassing Hei Yun, it would be difficult not to be distanced.

Bao Zixuan said with a smile: "This is a software developed by Heiyun itself. It has the technical parameters and appearance of most aircraft in the world. As long as we want it, we can easily call it out from the database and use it. But this

Each computer is not connected to the central computer cluster and can only be used as a stand-alone computer at present. Therefore, its capabilities are limited, but it can still meet the requirements of senior students."

Hearing that the Black Cloud database already contains data on most of the world's aircraft models, and engineers can call it out for use at any time. Old William was once again shocked. In terms of work efficiency alone, it was already ahead of McDonnell Douglas and even American aircraft manufacturing companies.

At present, major aircraft manufacturing companies in the United States still use manual drawing. The Xiangjiang company in the industrial desert actually uses computer drawing. You must know that the computer was invented by Americans, but now it is carried forward in the hands of Xiangjiang people. This is simply a irony.

Major universities, scientific research institutions and high-tech companies in the United States should really reflect on this.

Old William: "According to what you said, the nose of the aircraft should adopt a diamond-shaped structure. The circular radar reflective surface is too large, which is not conducive to stealth."

After finishing speaking, Bao Zixuan was seen operating on the computer. The three of them were a little stunned; not only Debbie Dickinson, Old William, but also Janice Dickinson after taking care of little MacDonald.

, also joined the small circle.

Bao Zixuan's hand speed was so fast that several people couldn't see clearly.

In less than a minute, the diamond-shaped machine head has been designed.

It was so fast to see it, and there was no trace of the previous image. It was incredible to old William. McDonnell Douglas must get this software, and he would not hesitate to pay a small price.

But now is not the time. First, we need to have a comprehensive understanding of the specific performance of the software before making a decision.

William Sr.: "The fuselage should be flat and integrated, while the wings should have a diamond-shaped structure; and a tilted tail should be used."

According to Old William's request, Bao Zixuan once again controlled the computer work.

After a while, according to Old William's request, the basic model of the aircraft was designed.

After that, the two began to build the aircraft around the details and began to continuously improve the structure and functions of the entire aircraft.

Seeing an airplane being designed in this way, the two Dickinson sisters began to have stars in their eyes. It turned out that the man from science and engineering was so charming, but he was really ignorant before.

When the basic details of the aircraft have been created, the aircraft appears on the computer screen.

After seeing the plane, Bao Zixuan remembered a classic model from his previous life that was not in service - the YF23; Black Widow.

The YF-23 fighter, nicknamed: Black Widow, is a test fighter model jointly designed by Northrop and McDonnell Douglas in the 1990s to bid for the Advanced Tactical Fighter (ATF) contract. Later, the U.S. Air Force announced that the YF-22 had won the

Choose the winner. Only two prototypes of the YF-23 fighter jet were produced, both of which are no longer flying.

The first prototype of the previous YF-23 was shipped from the factory on June 23, 1990, and the first test flight was conducted on August 27. The first YF-22 did not leave the factory until August 29; the first flight was carried out on September 29. A test flight. The yf-23 reached the supersonic cruise record of Mach 1.43 without using an afterburner during its fifth test flight on September 18, and the yf-22 reached Mach 1.58 on November 3. The yf-23 The two prototypes left the factory on September 29; the two prototypes used different engines: the first prototype used the Pratt & Whitney YF119, and the second prototype used the General Electric YF120, which was just the reverse of the YF-22.

The design concept of the yf-23 prototype is very different from that of the yf-22. In addition to using many existing components, the yf-23 flight test plan does not include test firing of air-to-air missiles and verification of high-angle-of-attack flight. Capabilities are mostly collected and verified through wind tunnel testing. According to the test results, the YF-23 has no angle of attack restrictions, and the aircraft can easily resume stable flight from any spiral. It only has difficulties when the missile door is open.

The YF-23 has conducted a total of 50 test flights, totaling 65 hours, with a maximum flight speed of Mach 1.5, a maximum load of 7g, and a maximum angle of attack of 25 degrees.

Compared with the yf-22, the yf-23 has a longer fuselage and a single wing. The front and rear edges of the wing are swept back and forward by 40 degrees respectively, similar to a rhombus. There is no horizontal control surface at the rear of the fuselage. A vertical control surface tilted 50 degrees outward replaces both.

The air inlet is located under the fuselage near the leading edge of the wing. The air inlet and air inlet are fixed structures with no movable parts, which not only reduces weight but also avoids increasing the frontal radar reflection cross-section. Air inlet It is bent upward inside the fuselage to connect to the engine located on the back of the fuselage. The nozzle is located in the middle of the cambered vertical control surface. The nozzle cannot be directly seen from the rear and below, which reduces the intensity of the infrared signal and also limits the installation of vector nozzles. feasibility.

It seems that old William must have participated in the design of the YF-23 in his previous life, otherwise it would be impossible to design the aircraft like this. It was just that the performance was too advanced, or it was for balancing needs, so it was ultimately rejected. It may be a pity, and this is also The reason why the old man is not widely known.
