At that time, McDonnell Douglas had already been acquired by Boeing, at least the signs were very obvious. The loss of military orders had little impact on Boeing. But the loss of orders for fourth-generation fighter jets from the United States forced Lockheed Martin to close down. In order to maintain strategic balance, yf-

The bid was successful at 22.

However, in the eyes of most people, the YF-23 is a rare classic. Since there is a chance, it must be produced. This fighter is more like a product that was eliminated in order to maintain a certain balance. With its own technical strength and

Combat performance has nothing to do with it.

I saw that in just one hour, the basic framework of a fourth-generation mobile phone was developed. What speed is this? Previously, it would have taken McDonnell Douglas at least a month to develop to this extent. It also required good cooperation among various departments.

The designer is in a state of overflowing inspiration.

Computer design of aircraft is bound to be a future development trend. Heiyun has obviously already moved ahead and can seize the opportunity when other American aircraft manufacturing companies are not interested.

Bao Zixuan smiled and said: "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 wind test and flight control inspection on a computer? What kind of operation is this? It is really unbelievable and unprecedented.

William Wales-Douglas said in surprise: "Wind tunnel testing can still be completed in a computer, and it can also simulate takeoff. Computers have developed to such an extent that it seems that before, McDonnell Douglas, including the U.S. auto industry, has lagged behind.

.”

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

That would be such a loss.”

When they heard that a small laptop cost 1 million US dollars, the three people present felt that they had heard wrongly. Could it be that this computer was made of gold, but it didn't look like it!

At this time, Debbie Dickinson finally understood what her sister said. The little money they earned was nothing in the eyes of super tycoons. The money they earned in a year was only enough to sell a laptop, and that was even if the two of them couldn't live without food.

Drinking case. This is the gap, a gap that is simply insurmountable.

Bao Shaofu's laptop was specially customized by Heiyun Laboratory; the chip, screen, and software optimization have been enhanced. Of course, there are some exaggerations, even if the computer performance is advanced. But after all, it is just a small laptop, which can at most

Do some simple tests. If you want to complete a comprehensive test, you must also connect to the central computer cluster to mobilize computing power.

But even so, it's really a bit scary.

Bao Zixuan started operating on the computer, while Old William stared at the screen. The aircraft soon appeared in the wind tunnel, and the simulated wind tunnel was almost the same as the real wind tunnel.

When the wind tunnel test started, the Dickinson sisters only felt it was fun. Old William was an expert and could see at a glance that although there were some differences between the wind tunnel test and the real wind tunnel test, it would not affect the overall situation. It was very much like watching a video of the wind tunnel test.

, computers are so magical.

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

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

Old William also felt that although the airplane was very good, it was not perfect enough. Could it be that computer simulation could really detect it? So he immediately replied: "Junior, this computer is so amazing. Please let me open my eyes more."

Although the two Dickinson sisters saw the excitement, the shock they received today was enough. It turned out that there were so many unknown things in the world, and now their eyes were filled with little stars when they looked at Bao Zixuan. It might have been because of the other party before.

His wealth is now conquered entirely because of his talent.

This is a real man. Even if he is not favored by Bao Zixuan, he will still find a talented man in science and engineering to marry. At this time, Debbie Dickinson actually came up with this idea. It can be seen that Bao Zixuan has brought people invisibly.

Change.

According to the opinions given by the computer, Bao Zixuan began to modify the aircraft's appearance design; after a while, the modifications were completed.

Old William was very satisfied when he saw the revised design; at least it was more in line with aerodynamic principles than before.

After that, the second wind tunnel test began, and the computer quickly gave suggestions for modifications. The cycle continued like this, and soon a fighter jet that Old William was extremely satisfied with appeared in front of his eyes.

Conducting multiple simulated wind tunnel tests has a lot to do with computer performance. Laptop computers have limited computing speeds, making it difficult to complete such a huge amount of calculations at once.

In addition, the aircraft still has a lot of room for modification, but the laptop computer can no longer calculate it. It is necessary to return to the Heiyun headquarters and use the computing power of the central computer cluster.

But even so, old William was very surprised. What kind of operation was this? The computer could actually complete the work of a human being for several months or even longer.

This is just a laptop computer. If an industrial computer is used, it is unimaginable how the aircraft will be modified.

The most troublesome part of developing an aircraft is wind tunnel testing, which often takes several months to build. After that, continuous improvement is required, which wastes a lot of manpower, material resources, and financial resources. Now Bao Zixuan can do it with a computer, which is unprecedented in the era.

It's developing so fast.

The two Dickinson sisters also felt that this aircraft was really beautiful, more beautiful than any aircraft 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 aircraft is increasingly in line with people's aesthetics.

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

The aircraft designed by the two people jointly conforms to the aerodynamic principles from the appearance. If advanced auxiliary equipment is added, it will definitely become a star fighter.

The two Dickinson sisters didn't understand why the old man was so excited all of a sudden. Isn't it just a sketch of a beautiful airplane?

It seems that he still doesn't understand the industry. Old William is not a person who gets excited easily. If you want to be with a man in science and engineering, you really need to have a comprehensive understanding of them.

Bao Zixuan: "The wind tunnel test is basic. If you want to make detailed modifications, you need to go back to the Heiyun headquarters and access the computing power of the central computer. Although it is not perfect, it is basically enough."

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

Although Old William was a little distracted, he quickly responded and 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 the effect is."

Old William was a little dumbfounded when he heard this. He was very familiar with the f404-ge-400 engine.

f404-ge-400 low bypass ratio turbofan engine, a single afterburning thrust of 7200 kg, the engine weight is 983 kg, the thrust-to-weight ratio is 7.4, the inlet adopts a fixed inclined plate design, located on both sides of the fuselage under the wing root

.

The aircraft can carry 4,990 kilograms of fuel inside, and can also hang three auxiliary fuel tanks. The total fuel load of the aircraft can reach 7,979 kilograms. There is also a stowable aerial refueling pipe on the right side of the head. The f404 is a low-bypass ratio turbofan.

With a pass ratio of 0.34, the engine has a three-stage titanium alloy fan, a row of fixed intake guide blades and a row of variable guide blades, and a seven-stage compressor.

The first three stages are variable blade stators, and the last is a single-stage high and low pressure turbine. The f404 engine has a simple structure and relatively few moving parts. The engine has good compressor stall characteristics at high angles of attack, and can even stall occasionally.

It recovers quickly by re-igniting the engine and afterburner. The engine responds quickly and it only takes 4 seconds from idle to full afterburner.

Regarding the data of the f404-ge-400 engine, old William can clearly memorize it because it was designed by General Motors specifically for McDonnell Douglas' flagship product, the F-18 Hornet.

Bao Zixuan's computer contains data about this engine. Could it be that there is commercial espionage within McDonnell Douglas? This possibility cannot be ruled out.

Bao Shaofu didn't know that his joke made the entire McDonnell Douglas company go crazy. The partners are right, but they can't let you steal the company's confidential information. This is a matter of principle, and McDonnell Douglas is not that easy to bully.

However, Old William would not reveal anything at this time. 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 General Motors. As an engine engineer in his previous life, he still knew the basic data of his competitors' products very well.

Seeing the boy in front of him inputting data so clearly, Old William became even more suspicious that there must be a serious problem with McDonnell Douglas or General Motors. Otherwise, Bao Zixuan would not be able to input this confidential value so skillfully and accurately.
