Shen Yiyi saw that Lin Xue had finally noticed him, and he breathed a long sigh of relief. I finally don't have to come back after dinner. In that case, he really looks like an overseer, and he doesn't have a good look.

Political Commissar Lin looked at his beloved daughter lovingly and asked, "I just came back too." But one by one, I've been here for a long time, and you don't know how to greet people. It's not that he doesn't know that his daughter is like falling into a state of selflessness when she first delves into something, but now that there are guests at home, it is polite to treat guests with a word of criticism.

Lin Xue looked at Shen Yiyi with some surprise: "Ah, you came early?" Why don't you call me. I didn't even notice you. "She's really weird. Shen Yiyi has always disliked to meddle in his own work, and it can even be said that he is in a state of "herding sheep" for his computing work. To put it nicely, Shen Yiyi completely trusts her, but Lin Xue always feels that Shen Yiyi actually has some resistance from the bottom of his heart when he sees the work of calculation. In fact, she didn't guess wrong, because people like Shen Yiyi, who were used to programming and computing on computers in later generations, now this kind of computing work that completely relies on people's physical and mental strength is tantamount to a kind of torture for her.

Shen Yiyi smiled and said to Lin Xue: "Yes, I've been here for an afternoon, but seeing that you are all so attentive, I am not too embarrassed to disturb you." If you are interrupted at that time, it will be very time-consuming and laborious to continue the calculation and re-engage in it. ”

Lin Xue nodded. Shen Yiyi is also telling the truth. When you concentrate on your work, once you are interrupted, your efficiency will obviously be affected when you start again.

"And what are you doing with us today? The inspection work is still here to comfort us? Cheng Ying asked jokingly. She was very cautious for being lazy last time and was severely criticized by Shen Yiyi for a while. During this time, she calculated the curve with Lin Xue, and Cheng Ying, who felt that she had made a lot of efforts, now feels that she has also contributed to the project, so she can joke with Shen Yi freely again today.

“BINGO！” Shen Yiyi cocked his thumb one by one, "You guessed right." I have come to comfort you and to inspect the work. ”

"Hey, I didn't see you bring anything delicious." Cheng Ying immediately vomited.

Shen Yiyi was not embarrassed at all by Cheng Ying's words, and replied: "It's not easy to eat, and on the day our paramotor flies, my father and Uncle Lin will definitely call a table in the small canteen to comfort everyone's hard work." But first we have to make our stuff first. ”

Lin Xue had a premonition that Shen Yiyi's purpose for coming this time. opened his mouth and asked Shen Yiyi: "Yiyi, you came over today, didn't you prepare for the assembly in advance?" ”

As soon as she said this, several other friends also looked at Shen Yiyi. They were a little nervous. This day is already confused, and if you want to get the results in advance, you don't want to live.

Shen Yiyi ignored the frightened eyes of her friends at all, and she admitted straightforwardly: "Yes, I hope that there will be a result today." Because I plan to start assembling the paramotor the day after tomorrow, after I get your results today, I can go to Sister Luo tomorrow. Start staking and cutting, and then you can ensure that you will be able to fly the paramotor the day after tomorrow. ”

"Ah............ No way. Sure enough, a few friends immediately wailed. However, Lin Xue estimated it in her heart, nodded and said, "It's a little difficult to calculate it today, but I'll try to give it to you before noon tomorrow." ”

"Lin Xue ......" Cheng Ying pointed at Lin Xue hurtfully, "You don't treat us as human beings, this is going to be considered dead." ”

Seeing that everyone rebounded so much, Shen Yiyi couldn't help asking, "But seriously." How far have you gotten now? ”

Before Lin Xue could speak, Liu Min replied softly: "Now it's 6 decimal places." So it takes a while to get to the exact 8 decimal places. ”

Shen Yiyi was dumbfounded by Liu Min's answer.

"You ...... You guys...... Let me say anything about you. "Shen Yiyi really wanted to look up to the sky and howl.

Lin Xue said embarrassedly: "Because the calculation is more complicated, although we have been calculating for the past few days, the progress has not been able to go up." But since you have to do it tomorrow, I'll do it all night tonight. ”

Seeing that the remaining few people were about to scream again, and then looking at the reluctant gaze in the eyes of Political Commissar Lin, Shen Yiyi hurriedly said, "Okay." My eldest lady, you're really making a big joke. ”

Lin Xue looked at Shen Yiyi with some puzzlement, not understanding what was wrong with her.

"My eldest lady, you are an academic talent, and you don't understand the reality of engineering applications. Mathematically, of course. We all require it to be very precise, but in practice, we can't do it exactly in production. It is important to know that there are manufacturing errors, measurement errors, and even the effects of thermal expansion and contraction, and the dimensional changes caused by these factors make your previous calculations accurate, and the products produced cannot be guaranteed to be exactly the same. Therefore, when we calculate the size, we can achieve three decimal places, which is already very accurate and dimensional. Shen Yiyi said helplessly. She also complained a little about herself, she didn't explain this problem to everyone before, which made everyone suffer for a while.

Cheng Ying's eyes widened: "What, it's only three decimal places?" But when we joined, we had already calculated to four decimal places. Have we been in vain these days? ”

Shen Yiyi spread his hands one by one: "From my point of view, what you calculated is of little value." But for you, it's still useful. At least it exercises your numeracy skills. I believe that the calculations in the past few days will make your calculation proficiency improve greatly. ”

Looking at Lin Xue's somewhat complaining eyes, as well as the relieved but unwilling eyes of the other friends, Shen Yihe laughed one by one. Sure enough, other people's pain is the source of their own happiness, hahaha.

Now it seems that this curve has been obtained, and it is more accurate than I expected.

After getting the formula of the airfoil curve from Lin Xue, Shen Yiyi hurriedly left the scene as soon as possible. If she stayed a little longer, she was afraid that she would be vented by everyone present.

Early the next morning, Shen Yiyi went directly to Luo Yufeng's factory with the formula. The night before, not only did I get the wing curve smoothly, but I also got good news from Luo Yu - the engine and fan have been manufactured. And the test results of the materials in the test laboratory also completely confirmed Shen Yiyi's original conjecture, and all of them were qualified.

Therefore, now as long as the first wing is sewn out, it is fully ready for test flights.

Luo Yufeng had made an appointment with Shen Yiyi in advance, so he waited in the costume factory early in the morning. As soon as she saw Shen Yiyi enter the door, she immediately dialed a few masters in the factory.

Shen Yiyi spread out the formula of the airfoil curve on the palm of his hand to the few masters who were called by Luo Yufeng. The designers in the factory immediately began to take out the calculator to calculate the expansion of these curves and the preparation method of the layout.

After Shen Yiyi threw this job to the professionals, she began to chat with Luo Yufeng regardless of it. Basically, Shen Yiyi thinks that the unfolding diagram is a manual work, because the calculation method is very clear, but it is a little cumbersome. It is important to know that in later generations, there is a special software that can directly generate an unfolding diagram by using a program that has been programmed in advance. Thinking of this, Shen Yiyi missed the laptop he had placed next to his bed before he crossed over. You know, there are a lot of pirated professional software installed in it!

However, then again, it is precisely because there are no such powerful calculation tools in this era that the formula I came up to cheat a professional degree has now become the basis for others to think that I am a prodigy who only comes out once in decades. This is really a loss and a gain.

Shen Yiyi was thinking nonsense there, Luo Yufeng was not ready to let her go, and chased her to ask if the school uniform business would continue.

Shen Yiyi listened to Luo Yufeng's question one by one, and thought to himself, if he relied on this school uniform alone, it would not be easy to make the business bigger. However, he already has a basic idea, but the problem is that he can't easily hand it over to Luo Yufeng now. I don't know what she did when she asked her to register a new company. Originally, she had promised that she would urge this matter, but later she was sick and hospitalized, so she didn't keep an eye on this matter. There is no settlement in this matter, and she will never agree to assign the follow-up plan to her.

But speaking of this, today is not a good opportunity to discuss. Shen Yiyi's goal today is to get his paramotor out first. So she dealt with Luo Yufeng's problem first without saying a word, but her eyes were staring at the work of a few old masters over there.

Sure enough, several masters were all familiar with it, and quickly determined the specific size of the lofting, and after checking it repeatedly, the master in charge came over to ask Luo Yufeng if he could start cutting immediately.

Luo Yufeng turned his head to look at Shen Yiyi, Shen Yiyi nodded, and Luo Yufeng said to them, "Let's start." Everyone, be careful, don't go wrong. ”

After the teachers got the order, they immediately divided labor and cooperated. The two of them went to the warehouse to bring the few feet of fabric, and some people here immediately emptied the workbench and prepared the tool ruler. Looking at their well-organized work scenes, Shen Yiyi admired his foresight a little. Sure enough, it is necessary to leave professional things to professionals. If your own group of children do the same work, not to mention the efficiency or anything, and even the possibility of mistakes can be extremely high, how can you make yourself feel like you are now, and you have a feeling that you are in control of everything?

As the nylon fabric was drawn with lines and gradually cut, Shen Yiyi could already see the picture of the paramotor soaring into the sky in the courtyard tomorrow. It must have been a moment of accomplishment, she thought. (To be continued......)

PS: Finally, today's amount can be sent out a little earlier.

Let's see, the one who has a ticket in his hand is the last day, vote for it, don't hide it, it will be wasted.
