v2 Chapter 912： Drunk Design Plane II

At that time, McDonnell Douglas was acquired by Boeing, at least the signs were already very obvious. Losing military orders has little impact on Boeing. Lockheed Martin must go out of business if it loses orders for the fourth-generation fighter jets in the United States. In order to maintain the strategic balance, the final YF-22 bid was successful.

However, in the eyes of most people, the YF-23 is a rare classic. Since there is a chance, he must be produced. This fighter is more like a product that was eliminated in order to maintain a certain balance, and has nothing to do with its own technical strength and combat performance.

It took only one hour to see that the basic framework of a fourth-generation machine was developed. What is this speed? It took McDonnell Douglas at least a month to develop to this level before. It also needs to cooperate well in various departments, and the designer is full of inspiration.

Computer design of aircraft is bound to be the future development trend. Heiyun has obviously come to the front, and he can seize the opportunity when other aircraft manufacturers in the United States are not interested.

Bao Zixuan said with a smile: "Senior William, do you want to conduct a wind tunnel test on the aircraft, and then conduct a flight test."

Is it possible to simulate the wind test and flight control test in the computer? What kind of operation is this, it is really incredible and unprecedented.

William-Wales-Douglas said in surprise: "Wind tunnel testing can still be done in a computer, and it can also simulate take-off. The computer has developed to such a degree that it seems that it was really sitting on the sky before, and McDonnell Douglas, including the American auto industry, has fallen behind in the United States. ."

Bao Zixuan: "This laptop in my hand is a special customized version, and it can be said to be the best laptop in the world. The cost alone has exceeded 1 million US dollars. If you can't even do simple simulated wind tunnel tests and take-off tests, That would be a shame."

Hearing that a small laptop costs $1 million, the three people at the scene felt that they had heard it wrong. Could it be that this computer is made of gold, but it doesn't look like it!

At this time, Debbie Dickinson finally understood what her sister said, the little money they made was nothing in the eyes of super tycoons. The money earned in a year is only enough to sell a laptop, and it is still in the case of two people not eating or drinking. This is the gap, and one simply cannot bridge the gap.

Bao's richest man's laptop is specially customized by Heiyun Lab; the chip, screen, and software optimization have been enhanced. Of course there are some exaggerations, even with advanced computer performance. But after all, it is just a small notebook, and it can do some simple tests at most. If you want to complete the full test, you must also link to a central computer cluster to mobilize computing power.

But even so, it's kind of scary.

Bao Zixuan started to operate on the computer, and Old William stared at the screen. The plane soon appeared in the wind tunnel, and the simulated wind tunnel was almost the same as the real one.

The wind tunnel tests began, and the Dickinson sisters were just having fun. Old William is an expert, and at a glance, he can see that although there are some gaps in the Tongzhen wind tunnel test, it will not affect the overall situation. Much like watching a video of a wind tunnel test, the computer is so magical.

The first test was completed quickly, and the computer immediately gave those unreasonable designs, which were listed very clearly.

Bao Zixuan said with a smile, "Some aspects of the wind tunnel test are not very reasonable. Should we improve it?"

Old William also felt that although the plane was very good, it was not perfect. Could the computer simulation really detect it? So he immediately replied: "This computer is so amazing, my brother, let me open my eyes more quickly."

Although the two Dickinson sisters watched lively, they were shocked enough today. It turns out that there are so many unknown things in the world, and looking at Bao Zixuan at this time is even more full of little stars. It may have been because of the wealth of the other party before, but now it is completely conquered because of talent.

This is the real man, even if he doesn't get the favor of Bao Zixuan, he has to find a talented engineering man to marry. At this time, Debbie-Dickinson actually came up with this idea, which shows the change that Bao's richest man has brought to people invisibly.

According to the advice given by the computer, Bao Zixuan began to revise the shape of the aircraft; the revision was completed after a while.

Seeing the revised design, the old William was satisfied; at least it was more aerodynamic than before.

After that, the second wind tunnel test was started, and the computer quickly gave suggestions for revision. In this way, a fighter plane that Old William was extremely satisfied with soon appeared in front of him.

Performing multiple simulated wind tunnel tests has a lot to do with the performance of the computer. The computing speed of the notebook computer is limited, so it is difficult to complete such a huge amount of computing at one time.

In addition, the aircraft still has a lot of room for modification, but the notebook computer has not been able to calculate it. It is necessary to return to the Black Cloud headquarters and use the computing power of the central computer cluster.

But even so, old William was very surprised. What kind of operation is this, the computer can actually complete the work of human beings for months or even longer.

This is just a laptop, if using an industrial computer. Then I can't imagine what the aircraft will be modified into.

The biggest headache for developing an aircraft is wind tunnel testing, which often takes several months to model. After that, continuous improvement is needed, and a lot of manpower, material resources, and financial resources are wasted. Now Bao Zixuan can do it with a computer. The development of the times is really fast.

The Dickinson sisters also thought the plane was beautiful, more beautiful than anything they had ever seen.

In fact, there is a common saying in the aviation industry that the more beautiful the aircraft, the more scientific the aerodynamic layout; this is also the main reason why the appearance of the aircraft is more and more in line with people's aesthetics.

Looking at the computer screen, old William said excitedly: "This is the plane in my mind, this is the plane in my mind."

The aircraft jointly designed by the two people is very aerodynamic in appearance. If coupled with advanced auxiliary equipment, it will definitely become a star fighter.

The Dickinson sisters did not understand why the old man was so excited all of a sudden. Isn't it just a nice sketch of an airplane, so what!

It seems that he still does not understand the industry. Old William is not a person who is easily excited. If you want to be with engineering men, you really need to have a comprehensive understanding of them.

Bao Zixuan: "The wind tunnel test is basically the same. If you want to make detailed modifications, you need to go back to the Black Cloud headquarters to get the computing power of the central computer. Although it's not perfect, it's basically enough."

"The next step is to test the aircraft and see how it performs."

Although old William was a little distracted, he still reacted quickly; he nodded quickly.

Bao Zixuan said with a smile: "Then we will install two F404-GE-400 engines produced by General Motors on the aircraft and see how it works."

Hearing this, Old William was a little dumbfounded. He was familiar with the F404-GE-400 engine.

F404-GE-400 low bypass ratio turbofan engine, single afterburner thrust of 7200 kg, engine weight of 983 kg, thrust-to-weight ratio 7.4, the air intake adopts fixed inclined plate design, located on both sides of the fuselage under the wing root .

The aircraft can carry 4,990 kg of fuel inside, and three auxiliary fuel tanks can be hung. The total fuel capacity of the aircraft can reach 7,979 kg. There is also a stowable aerial refueling tube on the upper right side of the head. F404 is a low bypass ratio turbofan with a bypass ratio of 0.34. The engine has a three-stage titanium alloy fan, a row of fixed intake guide vanes and a row of variable guide vanes, a seven-stage compressor, and the first three stages are variable vanes The stator, and finally the single-stage high and low pressure turbine. The F404 engine has a simple structure with relatively few moving parts. The engine has good compressor stall characteristics at high angles of attack, and even occasional stalls can quickly recover on their own by re-ignition of the engine and afterburner. The engine is responsive, going from idle to full afterburner in just 4 seconds.

Regarding the data of the F404-GE-400 engine, old William can clearly memorize it. Because that's what GM designed specifically for McDonnell Douglas' flagship F-18 Hornet.

Bao Zixuan's computer has the data of this engine Could it be that there is a commercial espionage inside McDonnell Douglas, this possibility cannot be ruled out.

The richest man Bao did not know one of his jokes, which made the entire McDonnell Douglas company jump. The partner is right, but it doesn't allow you to steal the company's confidential information. This is a matter of principle, and McDonnell Douglas is not that easy to bully.

But at this time, old William didn't show anything, he could only say with a wry smile: "Okay! Let's see how the aircraft performs after the engine is installed."

Bao Zixuan began to implant parameters into the aircraft engine. In fact, these were not leaked by McDonnell Douglas or GM. As an engine engineer in my previous life, I still knew the basic data of competitors' products very well.

Seeing such a clear input data from this kid in front of him, old William even more suspected that there must be a serious problem in McDonnell Douglas or GM. Otherwise, Bao Zixuan would not be able to be so proficient and accurately enter this confidential value.
