Old man Xiao Yizhan pointed out the essence of this problem. Yes, how can An Zhusheng report the problem of the material institute? In particular, this problem is simply caused by your previous negligence. Speaking of which, An Zhusheng also took advantage of other people's materials, and damaged other people's equipment, but people didn't ask you for compensation, isn't this style a little big?

An Zhusheng thought about this clearly, so he could only smile bitterly. Yes, now he does not have the position to criticize other materials for failing to fulfill their responsibility to test the physical properties of high-temperature materials, especially when he is the initiator of this problem.

When this topic comes to this, we still have to go back to square one. So An Zhusheng didn't talk about those digressions, and asked Xiao Yizhan directly: "Old Xiao, what do you mean, this material is likely to be able to withstand high temperatures?" ”

Xiao Yizhan nodded: "Yes." Although this family of aluminum alloys was previously mainly used in the structure of aircraft, it is also possible that it can be applied to engines. And, as you can see, the engine itself is a piston engine, and the temperature is not as high as that of a gas turbine. If it's just about 400 degrees Celsius, I don't think it's a big problem. ”

An Zhusheng nodded: "You have a point. In this way, I see that this material has the opportunity to do a high-temperature test, otherwise it is still not reassuring. ”

Xiao Yizhan said: "Of course, it is best to do it, but the question is where to do it. ”

"It's a big deal to take samples and go to Beijing. The Chinese Academy of Sciences should also have the corresponding instruments. ”

The two old mages were exchanging opinions on the issues they were concerned about, but the other technicians they brought out were nervously looking at the pile of product drawings brought by Xiao Yizhan one by one. They found that the parts they drew with a pencil on paper, in terms of the materials used and the technical routes they used, were different from the small engines they had seen before. Although, as 606. They are used to seeing all kinds of jet engines, but when the 608 Institute and other units in the same industry held a review meeting, there were still many people here who had the opportunity to attend. What they saw in those meetings also seemed to be very different from what was on the drawings. Attentive people took out the paper and wrote down little by little the differences between the set of drawings they found by Shen Yiyi and the parts drawings of other projects in their memory.

Therefore, when the differences in all these recorded parts drawings were handed over to An Zhusheng. The old expert's eyes were about to pop out. If you count carefully, the differences listed before and after can be written on two A4 sheets of paper.

An Zhusheng, who was pulling Xiao Yizhan to look at the two A4 sheets of paper against the drawings, let out this or that exclamation from time to time: "Ah, how can the tolerance here choose this grade?" On the other hand, why is that one much lower...... And this one...... The material of this sheet is also a material that has not been used before...... It's a very delicate structure......"

There is a kind of person called a technical maniac, which describes a group of professionals who are engaged in engineering and technical work. Their success comes from their obsession with mechanical design. Any new design, in their eyes, is extremely attractive. Especially when they find something in someone else's design that they have never seen before, they are so excited that it feels like they have just eaten a French meal.

So. When An Zhusheng and the others finished reading this set of drawings, they had a little taste of the work, and intuitively felt that the engine that this set of drawings might bring was a brand new machine, and it was very likely that the performance was quite good. An Zhusheng did not believe that this set of drawings was from Xiao Yizhan's hand. Lao Xiao is of course a well-known expert in China, but his specialty is not in the engine after all. In the machinery industry, although it is not said that it is interlaced like a mountain, it is necessary for a person who has not been engaged in engine design for a long time to draw such a set of drawings in front of him. That's really an impossible task.

He asked Xiao Yizhan: "Old Xiao, where did this set of drawings come from?" Don't tell us you painted it. Because we don't believe it. ”

Old Man Xiao doesn't care. At his age, he doesn't need to rely on plagiarizing other people's wisdom and hard work to achieve his own little reputation. So he also said calmly: "Of course it's not me." After thinking about it, he asked a little funny: "But, Lao An, what would you think if I told you that this set of drawings came from the hands of a girl who was only 16 years old?" ”

"What? Impossible! An Zhusheng almost jumped up in surprise. The few technicians next to him who were listening to the two old experts also widened their eyes in disbelief.

"But that's the truth." So Mr. Xiao Yizhan started from scratch. How did his little grandson get to know Shen Yiyi, and then brought his classmates to join such a team, how did everyone start to cooperate and divide labor, and how did his little grandson let himself discover Shen Yiyi's magical formulas, as well as the slide rule he found in Shen Yiyi. And there, Shen Yiyi explained how he came up with this set of engine drawings and asked him for help. This story made all the people present show incredible expressions.

After a while, Old Man An Zhusheng found his voice: "Old Xiao, I heard it right, right?" Are you saying that this set of pictures, and the things you mentioned, were really just made up by that 16-year-old girl? ”

Old Man Xiao smiled proudly: "I can't believe it, right? Honestly, if I hadn't experienced it myself, I wouldn't have believed it. ”

An Zhusheng thought for a while, and suddenly asked Xiao Yizhan: "Old Xiao, where does this classmate Shen Yiyi live?" I think it's better for us to discuss some issues in the drawings of this set of engines. ”

Old Man Xiao suddenly became alert: "Lao An, what are your ideas?" I can tell you, this Shen Yiyi was discovered by me first, and I am going to train to take over my class in the future. Our Shen Fei lacks such a spiritual talent to take over. ”

An Zhusheng saw that it was broken, and argued indifferently: "This is not a thing, and whoever finds it is whoever finds it." Let me tell you Xiao Yizhan, at least the little girl has now drawn a complete set of engine drawings, and you haven't drawn those aircraft drawings yet, right? What does this mean? This shows that this little girl is more interested in engines than in airplanes, which is why she studies engines so thoroughly. Moreover, everyone knows that our country's engine technology is backward, and we need such talents with Huigen to join our research team to mobilize Yang. ”

The two old men actually started to fight at this time, if Shen Yiyi knew it on the spot, he would definitely be crying and laughing.

Fortunately, it is not early at this time. Under the reminder of the staff, the two old urchins finally remembered to get down to business. Xiao Yizhan and An Zhusheng agreed to let the test factory of the 606 Institute find some materials first, and process a prototype according to Shen Yiyi's drawings. However, due to the time relationship, there is no way to carry out the high-temperature physical property test of the material that An Zhusheng has been thinking about for the time being. The two old men discussed waiting for the end of the New Year and looking for an opportunity to get a test piece to go to Beijing to find a machine to test. As for now, the top priority is to find a way to get Shen Yiyi's engine out first.

Xiao Yizhan was a little uneasy, and repeatedly instructed An Zhusheng to process it in strict accordance with the exact materials, sizes, and processes on the set of drawings given by Shen Yiyi, which made An Zhusheng a little unhappy: "Old Xiao, it's okay, I really can't believe me, what's wrong?" Don't you know me yet? I'm the most demanding of the following. You can rest assured, if there is the slightest error between the results of the final processing and the requirements on this drawing, my An Zhusheng's name will be written upside down. ”

Seeing that the old man said this, Old Man Xiao was also a little embarrassed, so he had to say curtly: "I'm not afraid that the New Year is approaching, will the workers in your institute relax?" At that time, if the construction period is delayed, my old man will not be able to speak in front of the juniors. ”

An Zhusheng almost patted his chest and promised: "Don't worry, I'm staring at it." I see these people who dare to be careless. But Lao Xiao, I can tell you, if the technology and materials we process are exactly the same as those marked on the map, and the performance is not good during the test, it means that this Shen Yiyi still needs to study and improve on the theory of power, then she must be asked to learn from my old man for two years, and you can't rob me when the time comes. ”

"You dream, there is no such possibility." Xiao Yizhan once again rejected An Zhusheng's attempt to dig the foot of the wall. The good apprentice and the successor of the mantle that Xiao Yizhan has in his eye must be guarded well, and he can't let people take it away.

The two giants of the aviation industry, in this form of almost jokes, finalized the production of the main components of Shen Yiyi's paramotor. And Shen Yiyi himself was already busy going to Luo Yufeng's factory to greet Luo Yufeng, who came back from Shanghai.

When the two met, it was naturally a sister and sister who met each other. However, after the two exchanged pleasantries, Luo Yufeng also took the initiative to mention the pile of agreements she signed in Shanghai. To know the importance of the nylon-66 material to Shen Yiyi, she had already noticed it from Shen Yiyi's constant concern, so she naturally had something to say about what others wanted to hear. This is also a knack that she has mastered in business for a long time.

Luo Yufeng also took out two samples and handed them to Shen Yiyi: "Well, this is for you to test in Shanghai." More samples will be sent later, but it may be after the New Year. ”

Shen Yi nodded. She's actually a little relieved now. Because almost all paramotors are now almost ready. She felt that it was better to get the income she might have as soon as possible, so she asked, "Sister Luo, have all the fabrics for the school uniforms you ordered shipped back?" (To be continued......)

PS: It's finally the second watch, and I'm tired.

I'm afraid there is no hope for the third watch. I'm so sleepy, I have to wake up early tomorrow.

For the sake of me yawning now, do you have any votes or something?

Of course, favorites and subscriptions are also important.
