Chapter 565: Thorny problem

It is a pity that Tan Zhenhua is indeed a layman in the aviation industry. Even though Song Wenhua spent two full hours on his "interrogation" and used various "coercive and lure" methods, all he could "consume" was only endorsement. A few words, such as the interpretation of the Chinese and English terms of "DSI inlet", such as several typical benefits of this type of inlet, for example, the design of this inlet may require complex fluid mechanics and massive calculations This last article is limited to nouns. Regarding fluid mechanics, Tan Zhenhua said that he knew nothing except for his face full of impatience and admiration.
So the final result is that Song Wenhua got a new concept that sounds like a fantasy, but it seems to be a little reliable but completely clueless, and Tan Zhenhua is searching for a little bit of information that he can think of. After he was cleaned up whether it was useful or not, Song Wenhua sneaked out of the room while he was thinking hard.
After leaving the room, Tan Zhenhua secretly wiped a cold sweat on his forehead. Song Wenhua's interrogation was sharp and straightforward, and he did not give him any chance to breathe. He was speechless and difficult to fight against several times. This news is just prevarication by hearsay.
It seems that rebirths can't arbitrarily disclose advanced technology at will, otherwise, there are too many places that are difficult to justify.
After calming his mind, Tan Zhenhua decided to go back to his room and rest for a while. In order to deal with Song Wenhua's cross-examination, he had spent a lot of brains and died a lot of brain cells. At this time, he must take a nap to make up for it.
It's a pity that the sky didn't fulfill everyone's wish. As soon as he was about to walk towards his room, he saw a door open in the corridor and a person was waving at him.
It is Chen Yijian.
Chen Yijian is looking for him now, 100% for the leopard's business, that is also one of Tan Zhenhua's heart knot, so he had to sigh in his heart his hard work and the ability to find trouble, and tried to put his face on his face. He smiled, and then walked over and asked, "Master Chen, are you looking for me?"
Chen Yijian said: "Yes, there is something really going on, Zhenhua, come to my room and talk."
When the two entered the room, Chen Yijian asked in a low voice: "Zhenhua, is it safe in this room?"
Tan Zhenhua was taken aback for a moment, then he recollected it and replied with a smile: "Master Chen, there are special people here and outside who have checked it out. You can rest assured that it is safe."
Just kidding, every time Mr. Shao goes out, he is always surrounded by a large group of people. Butlers, babysitters, cooks, doctors, and bodyguards are all indispensable. Therefore, as one of the most basic security measures, in Shao Before Liu Ye moved in, it was necessary to "check and clean" all the rooms carefully.
Chen Yijian nodded, and then whispered: "Zhenhua, after you visited Xijing last time, I met with the people from the navy and basically reached a consensus. The aerodynamic shape of the big 7 can be in accordance with your requirements. Our original third plan was developed. In fact, the Navy was also more optimistic about that plan, but if the third plan is adopted, the technical difficulty will rise to a higher level and the risk factor will be higher."
Tan Zhenhua knows that the "big 7" in Chen Yijian's mouth is obviously the "JH-7" fighter, and the so-called "third plan" is the central lift body that has been on the verge of elimination due to excessive technical difficulty and high processing requirements. +The side strip wing plan is exactly the plan he is optimistic about and strives to promote. So he nodded and said: "Master Chen, I don't understand technical matters, so you still need to check it out. Again, what I can do is just a little bit of logistical work."
Chen Yijian said, "In fact, I am looking for you today for this logistical matter."
Tan Zhenhua said strangely: "Oh? Chief Chen, what do you say?"
Chen Yijian replied: "According to our previous agreement, not only need to change the aerodynamic shape that has been basically determined, but also your requirements for time are very strict, which makes my work here seem very urgent, and time is sometimes It takes money to grab it..."
Tan Zhenhua interrupted Chen Yijian suspiciously and asked, "Master Chen, I remember the loan I got from the Bank of China. As soon as the money was received, I transferred it to you without any delay in a minute? There are 100 million. You are called poor again in just a few days?"
Chen Yijian hurriedly waved his hand and said, "No, Zhenhua, you are misunderstood. I am not asking you for money. You know, to design an airplane's aerodynamic shape, which involves massive wind tunnel experiments and data calculations. No matter, our wind tunnel is not as good as Mianyang’s, but the blow-down ratio is barely enough than the model. But this calculation is a big trouble. The equipment in our hands is really too bad. There are always problems, so I thought, Zhenhua, since you are studying in the U.S., can you find a way to buy us some advanced computers?"
Chen Yijian's request immediately reminded Tan Zhenhua of an important matter, and the priority of this matter is still quite high.
In his previous life, when he finally finished his studies and was assigned back to work in 4014, it was already 1988, but even in that year, the computer was still a rare object in China, even though it was an electronic engineering research institute. At that time, a large number of scientific researchers in the 4014 Institute were still working at the stage of traditional drawing and T-square. Whether it was a microcomputer for personal office and drawing or a central computer for large-scale analysis and calculation, the resources were very great. Shortage. This is the case for 4014 in 6 years, so how can the current 3603 be better?
And Tan Zhenhua, who has also worked with plates and T-squares for a period of time, knows deeply that these primitive equipment not only bring low efficiency, but also greatly restrict product design capabilities.
Therefore, it is necessary to solve this problem quickly.
To solve this problem, it is not only as simple as buying a few high-performance computers, but also matching software.
Tan Zhenhua, who was also a great engineering scientist in his previous life, set his goal without careful consideration. The computer, of course, chooses the highest-performance product that can be bought, and for the design software, he undoubtedly chose Gallo Dasso. The company's flagship product-CATIA.
Although the goal is determined, the next problem is even more difficult. High-performance computers certainly need excellent semiconductor industry support. Therefore, the current mainstream high-performance computers mainly come from the international business machines IBM, Cray Cray or Control Data CDC. , But without exception, all three companies are American companies!
But are they willing to sell?
