After Shen Yiyi finished arranging the work one by one, Lin Xue and the others couldn't wait to start work. Luo Yu saw that Fang Bing also started to calculate all of a sudden, and felt that he was suddenly empty, so he asked Shen Yiyi: "Classmate Yiyi, after my work here is done, will I join them and calculate with them?" ”

Shen Yiyi said: "If you want to count with them, it's not impossible, but it can't be now." I have some things for you to do. ”

As soon as Luo Yu heard that he had work to do again, he immediately asked, "What's the matter, tell me about it." ”

The old man Xiao Yizhan, who was listening next to him, also asked with interest: "Yes, classmate Yiyi, what is more important than this calculation, so that the support of the calculation team is not important?" Tell me about it, let my old man hear it. ”

Shen Yiyi sold it one by one: "It will disturb their calculations, let's go back to my house first." ”

Old Man Xiao had no choice, so he had to take his grandson to Shen Yi's family together.

When he entered the house, Shen Yiyi took out a set of stacked drawings from the prepared bag, handed them to Luo Yu, and said, "Luo Yu, this set of drawings is very important. Your task is to take this set of drawings to your father's factory and see if you can find a master worker to process and assemble it. ”

Luo Yu looked at the stack of pictures in his hand, but he was not paying attention but was snatched by the old man Xiao Yizhan.

Xiao Yizhan looked at the open drawings in his hand, frowned, and asked Shen Yiyi: "What is this......?" Drawings of the engine? Where did you get this diagram from? Did you draw this pencil drawing yourself? "This set of drawings is not an ordinary engineering drawing, it should be a blueprint made of ammonia or other potions, and there is no frame signature that the official drawings should have, but a set of processing drawings drawn with thick and thin pencils. This made Xiao Yizhan, an old technician, feel a little strange all of a sudden.

Shen Yiyi replied very calmly: "I painted it correctly." Exactly. This is a paramotor power system designed by myself. There's also a pair of propellers in there. Shen Yiyi simply took out another one from the stack of drawings and showed it to Old Man Xiao.

"Shen Yiyi, why didn't you think of using a ready-made engine?" Old Man Xiao is now more interested in Shen Yiyi. He didn't expect Shen Yiyi to actually design the engine. Generally speaking. For the current engineering technicians, the professionalism is getting stronger and stronger. Very few people are able to be generalists. Especially for the aviation industry, aircraft structure and design and engine design are very complex technical fields, and few people can cross borders. He didn't expect that the little girl in front of him would want to do these two things at the same time.

In fact, Shen Yiyi has a reputation for self-knowledge. She herself didn't think she was doing what a great thing she was doing right now. A paramotor, to herself, was at best something like a model airplane. Have you ever seen a model airplane enthusiast who doesn't take care of the model airplane from head to toe by himself. Of course, this paramotor is still larger than the size of ordinary model aircraft, so some of the things used on it still need to be specially processed.

Regarding Old Man Xiao's question, Shen Yiyi still had something to answer: "First of all." Presumably Mr. Xiao, you also know that our paramotor is not an ordinary sports umbrella. It requires a certain task, so the original motivation does not meet our requirements; Secondly, since we are now optimizing the design of the wing, why not optimize our dynamics at the same time? Xiao Lao, you also know that no matter how good the aerodynamic layout of an aircraft is, if it encounters a less ideal power, then not only the excellent performance of the aerodynamic design cannot be displayed, but it may make the aerodynamic layout that should be very successful. Become a dangerous design. ”

Shen Yiyi's words deeply shocked Old Man Xiao. This would not be possible without a broad understanding of the knowledge of aircraft design. Shen Yiyi's ability to talk about this issue shows that she does have a considerable foundation for aircraft design.

He suddenly noticed a detail on the drawing: "What." Do you use aluminum alloy for this engine? Do you know what the melting point of aluminium is? Do you have no problems with this material when the fuel is burning? ”

The engines of this era were basically still made of iron, and the aluminum alloy materials used in later generations of automobiles to reduce weight. For most engineers in this era, it may still be a crazy idea.

Shen Yiyi has the advantage of later knowledge. It is important to know that there are even many independent brands of engines in later generations. In order to improve the performance of the car, an all-aluminum engine is also used. The self-owned brand car that Shen Yiyi bought himself is one of them. And Shen Yiyi is a female engineer. She is also interested in getting into contact with the main components of these cars. Even because of various opportunities, she was able to contact the suppliers of various independent brand manufacturers, and she also had an understanding of the manufacturing technology of certain components. Therefore, in her design this time, she adopted some designs that seemed crazy and immature in this era, but in fact, they were selected from the application experience of later generations.

Facing Old Man Xiao Yizhan's question, Shen Yiyi replied very confidently: "Old Xiao, that's right, it's an aluminum alloy, but I'm sure this material can be used in my engine, no problem." She simply said to Mr. Xiao again, "Of course, the premise is that the processing requirements and process routes should be the same as those I marked on the map." ”

Looking at Shen Yiyi, who was full of confidence, Xiao Yizhan felt that facing Shen Yiyi, a little girl, the word surprise might be a norm for herself. The formulas she deduced were already a treasure trove for her, and then the slide rule she conceived with a few girls for structural calculations was an innovation that she had never tried before. But now, she actually told herself that she even reimagined and designed an engine herself, and it seems that she is still very confident in her design. What a wonder girl this is.

Shen Yi saw that Old Man Xiao hadn't spoken for a while, so he turned to Luo Yu and said: "Luo Yu, you take these drawings to Shen Fei, you must make it clear to them, my requirements are that the materials are according to the drawings, the processing is according to the drawings, and the assembly is according to the drawings, in short, you must not rely on the old experience of the workers and masters." Produce according to the drawing, then absolutely no problem. ”

Luo Yu nodded, and before he could speak, he was interjected by Mr. Xiao Yizhan: "Okay, one by one, girl, you don't have to pretend there, to put it bluntly, you said this to Xiao Yu in front of me today, aren't you beating my idea?" He is a child, what ability can he be able to mobilize the production workers in the factory? And I'm afraid it's not easy to find the materials you're looking for. Isn't it possible for Xiaoyu to do it himself? ”

Shen Yiyi grinned: "Ha Luha, you old man has seen through it." Then I'll get straight to the point. Old man Xiao, the requirements I made to Luo Yu just now, you old man don't think there is any problem. "She has always mastered the tricks of snake fighting.

Xiao Yizhan looked at her shrewd appearance, and once again made up her mind in her heart, she must not let this little fox be her grandson's daughter-in-law, otherwise she will have to count the money for her grandson if she is sold in the future. He glanced at Luo Yu angrily, and said to Shen Yiyi in turn: "How can it be okay, it's a big problem." First of all, I have to go to a few old friends at the metallurgical institute to see if there are any of these grades of materials that you specified. Anyway, I've never seen it in our factory. Then you have to go to the power flying factory to see if you can process these drawings. I'll do you a favor again, find a few old experts in our factory who are engaged in power, and my old buddies will help you review the drawings to see if there are any specific problems with your design. "Actually, the old man Xiao, who cherishes talents, has already made up his mind to help Shen Yiyi do this thing one by one, so why invite experts to discuss this kind of thing, he is determined to use his own face to invite people to participate in this project together. He really wanted to see how far Shen Yiyi, a little girl, could bring this project this time, and whether he could always make him feel bright.

Shen Yiyi naturally couldn't ask for it. With the great god of Old Man Xiao staring at the back, any kind of problem will definitely be solved. After all, the old man has a lot of protégés in Shen Fei, and his son-in-law is Shen Fei's boss, so his ability to mobilize resources is unparalleled. To be able to move this great god, to be honest, I didn't think about it at all before now. But now that there is such an unexpected joy, it would be a fool if I didn't make good use of it. And the old man, out of good intentions, took the initiative to ask someone to help him review the drawings, and Shen Yiyi was not afraid at all. Her design this time is actually a mature design that is rare now, but has been practical and verified many times in later generations, and there will be no big problems. Even Shen Yiyi had another idea. This thing gathers people in groups, Xiao Yizhan is at the level of the old man, and those old guys who are among the experts like him should not be fuel-efficient lamps. If you can connect with these old gentlemen who can be described as a bull in a certain field through these pictures, or even conquer them through your own design and gain their recognition, then if you want to implement your other "innovation" plans in Shenyang in the future, it will be a big help that you can't look forward to!

Therefore, almost when Luo Yu was a puppet, Xiao Yizhan was the master, and Shen Yiyi and his classmates directly finalized the trial production of this engine. (To be continued......)

PS: Finally the code is finished, hurry up and upload it. We talk about it, everyone still supports a lot, what a collection to subscribe to vote, give a little bit of power. After a few small talks, I heard that Ali is going to buy, will we change owners in the future?
