Chapter 912 (2/2)

But even so, old William was very surprised. What is this operation? Computers can actually complete human work for months or even longer.

This is just a laptop, if you use an industrial computer. It's hard to imagine what the plane would be like.

The biggest headache of aircraft development is wind tunnel testing, and modeling often takes several months. After that, it needs continuous improvement, which wastes a lot of human, material and financial resources. Now baozixuan can do it with a computer. The development of the times is really too fast.

The Dickinson sisters also felt that the plane was really beautiful, more beautiful than any plane they had ever seen.

In fact, there is a common saying in the aviation industry that the more beautiful the aircraft is, the more scientific the aerodynamic layout is; This is also the main reason why the appearance of 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 plane designed by two people together conforms to the principle of aerodynamics from the appearance. If advanced auxiliary equipment is added, it will certainly become a star fighter.

The Dickinson sisters did not understand why the old man was so excited at once. Isn't it a beautiful plane sketch, as for this!

It seems that he still doesn't understand the industry. Old William is not an easily excited person. If you want to be with men of science and technology, you really need to know them from all aspects.

Bao Zixuan: ”wind tunnel test is basically in contact. If you want to make detailed modifications. You need to go back to the black cloud headquarters and transfer the computing power of the central computer. Although it's not perfect, it's good that it's basically enough. ”

”Next, let the plane test fly and see how the performance is.”

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

Bao Zixuan smiled and said, ”then next, we will install two f404-ge-400 engines produced by general motors to see how the effect is.”

Hearing this, old William was a little embarrassed. He was familiar with f404-ge-400 engine.

F404-ge-400 low bypass ratio turbofan engine has a single afterburner thrust of 7200kg, an engine weight of 983kg and a thrust weight ratio of 7.4. The air inlet adopts a fixed inclined plate design and is located on both sides of the fuselage under the wing root.

The aircraft can carry 4990 kg of fuel inside, and can also hang three auxiliary fuel tanks. The total fuel capacity of the aircraft can reach 7979 kg. A stowable aerial refueling pipe is also installed above the 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 inlet guide vanes and a row of variable guide vanes, a seven stage compressor, the first three stages are variable blade stators, and finally a single-stage high and low pressure turbine. F404 engine has simple structure and relatively few moving parts. The engine has good compressor stall characteristics at high angle of attack. Even if it stalls occasionally, it can recover quickly by re ignition of the engine and afterburner. The engine responds quickly and takes only 4 seconds from idle to full afterburner.

Old William can clearly recite the data about f404-ge-400 engine. Because it was specially designed by general motors for McDonnell Douglas's flagship product F-18 bumblebee.

Baozixuan computer has the data of the engine. Is it that there is a commercial spy inside McDonnell Douglas? This possibility cannot be ruled out.

Bao Shoufu didn't know his joke, which made the whole McDonnell Douglas company jump. Partners are right, but you can't steal the company's confidential information. This is a matter of principle. McDonnell Douglas is not so easy to bully.

But at this time, old William would not show anything. He could only say with a bitter smile, ”okay! Look at the performance of the aircraft with the engine. ”

Baozixuan 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 a previous life, I still knew the basic data of competitors' products very well.

Seeing the boy's clear input data in front of him, old William doubted that there must be a serious problem in McDonnell Douglas or GM. Otherwise, baozixuan could not be so skilled and accurately input this confidential value.
