v2 Chapter 911： Designing an airplane after drinking

Seeing Bao Zixuan sitting next to him, Old William immediately had an idea. If you can put more things on this kid, even if the two companies do not cooperate in the future, McDonnell Douglas will not suffer.

Bao Zixuan has such a clear understanding of the fourth-generation fighter. If Heiyun has not carried out relevant research and development, it will certainly not be convincing. McDonnell Douglas is still in the theoretical stage for the fourth-generation fighter, and he has some ideas and suggestions on the black cloud, which will inevitably take the lead in the future research and development process.

At least it wouldn't hurt to communicate with such a person, and Old William didn't continue drinking. One is that he is older, and the other is that he understands how much he can drink. Although I don't have much contact with Bao Zixuan, I know that this kid can drink surprisingly well.

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

What does old William mean? Could it be that he drank too much, but he didn't look like it!

In fact, at this time, old William didn't drink much at all, and he was still very awake. At such an old age, you won't be mistaken because of drinking, that's what young people do.

I just heard Bao Zixuan's definition of a fourth-generation fighter jet, and the feeling of drinking was completely gone in an instant. This is a good opportunity. Old William is very cunning. It is not enough to hear the definition. He must see the shape of the fourth-generation fighter of Heiyun.

Fighter jets are different from civilian aircraft. It is impossible for McDonnell Douglas to cooperate with Black Cloud. 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. So the question is, what should I do if there is no relevant technical reserves yet, should I start from scratch?

Not only will it waste a lot of time, but most importantly, it will be impossible to start. There was no concept before and everything needed constant testing.

If you can dig out a little more from Heiyun Group and Bao Zixuan, it will definitely be handy when designing fourth-generation fighter jets in the future. Although the motive is impure, as long as the result can be obtained, who will care about other things!

Bao Zixuan: "Since Senior William is so interested, then treat it as a form of entertainment."

"Computer or hand-drawn, you decide."

Hearing Bao Zixuan talk about using a computer, William Wales-Douglas was very curious. Is it possible to use a computer to design aircraft sketches, just to verify it today.

Old William: "I can do hand-painting, 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 in tradition more.

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

Hearing that computers can do so much work, 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 his laptop.

Before waiting for the staff to do it, Debbie Dickinson immediately began to act. He tidied up the table so that Bao Zixuan could put his laptop on.

Both men looked at the woman who was just serving by the side without saying a word. Bao Zixuan didn't expect a model to be able to do this. It seems that he really underestimated the beauty in front of him before.

After turning on the computer, I saw the richest man just clicked a few times. A model of a fighter jet is presented, although it is only a sketch, but the outline is already very clear.

This made Debbie Dickinson feel amazing, not only as a beautiful model, but also as a professional old William. It turned out that the computer designed the plane so fast that it took him half an hour to draw this sketch alone. It seems that a lot of thinking needs to be changed, otherwise it will never keep up with the development of Heiyun.

At that time, let alone surpassing the black cloud, it will be difficult not to be drawn away.

Bao Zixuan said with a smile: "This is a software developed by Heiyun himself. The technical parameters and shapes of most aircraft in the world are available. As long as we want, we can easily call it from the database and use it. But this Each computer is not linked to the central computer cluster, and can only be used as a stand-alone computer at present. Therefore, its capacity is limited, but it can also meet the requirements of the senior.”

I heard that the black cloud database already has the data of most models in the world, and engineers can call it out for use at any time. Old William was once again shocked. In terms of work efficiency alone, he was already ahead of McDonnell Douglas and even American aircraft manufacturing companies.

At present, the major aircraft manufacturers in the United States still use manual drawing methods. The Xiangjiang Company in the industrial desert actually uses computer graphics. You must know that the computer was invented by the Americans, but now it has been carried forward in the hands of Hong Kong people. This is an irony, and America's universities, research structures, and high-tech companies should really reflect on this.

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

After he finished speaking, Bao Zixuan started to operate on the computer. The three of them were dumbfounded; at this time, not only Debbie Dickinson and old William, but also Janice Dickinson joined the small circle after taking care of little MacDonald.

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

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

See it so quickly, and there is no trace of the image before. Old William felt incredible, this software must be obtained by McDonnell Douglas, and he would not hesitate to pay a price.

But now is not the time. First of all, you need to have a comprehensive understanding of the specific performance of the software and make a decision.

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

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

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

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

Seeing a plane being designed like this, the Dickinson sisters began to see little stars in their eyes. It turns out that the engineering man is so attractive, he was really ignorant before.

When the basic details of the aircraft have been built, the aircraft is displayed on the computer screen.

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

The YF-23 fighter jet, nicknamed: Black Widow, is an experimental fighter model jointly designed by Northrop and McDonnell Douglas in the 1990s to bid for the Advanced Tactical Fighter (ATF) contract. Later, because the U.S. Air Force announced that the YF-22 was selected as the winner. A total of 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 took place on August 27. The first YF-22 will not leave the factory until August 29; the first test flight will take place on September 29. The YF-23 achieved a supersonic cruise record of Mach 1.43 without the use of the afterburner on its fifth test flight on September 18, and the YF-22 reached Mach 1.58 on November 3. The second prototype of the YF-23 was shipped on September 29; the two prototypes used different engines: the first prototype used a Pratt & Whitney YF119, the second prototype was a General Electric YF120, and the YF-22 Just upside down.

The YF-23 prototype design concept is very different from the YF-22. In addition to using many existing components, the YF-23 flight test plan did not include test-launching air-to-air missiles and verifying high angle of attack flight. Most of the capabilities are collected and verified by wind tunnel testing. According to the test results, the YF-23 has no angle of attack limit, and the aircraft can easily resume stable flight from any spiral Only when the missile door is open will it be difficult.

YF-23 carried out a total of 50 times, a total of 65 hours of test flight projects, the maximum flight speed reached Mach 1.5, the maximum load reached 7G, and the maximum angle of attack reached 25 degrees.

Compared with the YF-22, the fuselage of the YF-23 is relatively long, with a mid-wing single-wing, and the front and rear edges of the wing are swept back and forward by 40 degrees, similar to a diamond. There are no horizontal control surfaces at the rear of the fuselage, replaced by two vertical control surfaces that **** outward at 50 degrees.

The air intake is located under the fuselage near the leading edge of the wing. Both the air intake and the air intake adopt a fixed structure, and there are no movable parts, which can not only reduce the weight, but also avoid increasing the frontal radar reflection cross-sectional area. The air intake is bent upwards inside the fuselage to connect with 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 bottom, which reduces the intensity of the infrared signal and also limits the Feasibility of installing vector nozzles.

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 only because the performance was too advanced, or it was to balance the needs, that it was finally defeated. It may be a pity, which is why the old man is not widely known.
