Actually, it's really that it's not easy to assemble. Because the structure of the paramotor is actually really simple. The main thing that requires a relatively strong connection is the engine and the fan, and of course, the bracket. With Luo Yu's grandfather's old experience, and his apprentice as a senior technician, he was still an apprentice, and according to Shen Yiyi's previous drawings, it was only about half an hour, and it had already been properly assembled.

Watching Grandpa Luo take a torque wrench to calibrate the torque of that bolt one bolt at a time, Shen Yiyi's thoughts had turned to how to get the paraglider that was still soft and collapsed. Speaking of which, although in the eyes of Xiao Yizhan and An Zhusheng, the engine and fan that have been assembled now may be the things with higher technical content, but as the parachute wing that all the friends have worked hard for, in the eyes of Lin Xue, Liu Min, Cheng Ying and other friends, it is the real object of most concern. Who doesn't care more about the fruits of their labor?

Just now, Shen Yiyi took the time to ask Old Man Xiao, and it was a pity that because today was the homecoming day of Shen Fei No. 1 Middle School, the three boys from Shen Fei No. 1 Middle School could not come to this event today. Shen Yiyi believed that if Luo Yu and the three of them were here, they would definitely pay the most attention to what this paramotor wing would look like when it was stretched out.

A paraglider is a hollow structure, somewhat similar to a large balloon. In later generations, when the paramotor was to be propped up, there was a special air pump, which was very lightweight and easy to carry. There is also a special barometer on it to prevent overcharging or under-inflating. But in this era, Shen Yiyi has no other choice when he has insufficient time and resources. Because those things can only be purchased domestically when China becomes a factory in the world, and it is still the stage of China's economic take-off, so Shen Yiyi has not counted on these at all.

Fortunately, our revolutionary army. It was originally developed from the predicament of millet plus rifles and one poor and two white. The great man also once said that the creativity of working people is limitless. So, the quality of being a good engineer is about using the tools you have at hand to achieve the required functionality. So the day before, Shen Yiyi had already agreed with the small car class in the compound that he wanted to borrow the pump they used to pump the car tires, just to inflate the paragliders.

The matter of inflating was handed over to Master Shen one by one. Because she felt it was time to involve her father in such a thing. In this way, he will not always have the mentality of a spectator, and will regard this new thing as a career in which he also has a part. Of course, when Comrade Shen Jianguo worked very hard there, it was unknown whether he realized his daughter's little flower intestines in his heart.

The crowd gathered firewood and the flame was high. With the joint efforts of everyone, in a time far less than Shen Yiyi expected, basically the big umbrella that Shen Yiyi had fiddled with in his previous life as common flying enthusiasts appeared in front of his eyes completely. Shen Yiyi himself felt very excited. Although the gadget in front of him is not as colorful as those mature commercial products in later generations, and even because the component materials used happen to be silver background colors, in Shen Yiyi's eyes, he even feels that this paramotor looks a little ugly. But perhaps because he participated in the whole process, and even led such an industrial design for the first time in his life, he pulled up a small team of those concepts in his mind, and then found a suitable way to implement them, and with the support of some enthusiastic and talented people, he presented them to everyone in the form like today, which was so complicated that Shen Yiyi wanted to cry.

Unlike her mixed feelings. The other people present looked at such a "parachute" and a small engine with a fan, and they all looked at Shen Yiyi with some admiration. Xiao Yizhan and An Zhusheng have no problem with the flight principle originally conceived by Shen Yiyi. They are all engaged in the aviation industry. They also learned about Shen Yiyi's entire design process through different channels, and Shen Yiyi's design ideas were not kept secret from them, so they didn't have too many doubts about being able to fly after such a combination of components. What's more, Mr. Xiao also learned before that the French had indeed demonstrated such a flying instrument in China. However, the old men, who were accustomed to the sturdy flying machines of airplanes, saw such a somewhat rough and rudimentary thing with their own eyes. I'm still a little worried about whether the strength of this aircraft is enough.

As for the others, such as Lin Xue and the three of them, as well as the parents in the courtyard led by Master Shen, they felt very curious when they saw these parts that were still glowing with a silver-gray luster. There are a lot of capable people in the compound. But in the past, the handicrafts that were really created were probably the carpenters in the construction class who would make some furniture or something. It's the first time that this iron lump has made a thing that is said to be able to fly into the sky. The big guy may still have a small question mark in his heart about whether this thing can go to heaven or not, but in front of Comrade Shen Jianguo, the praise and praise of Shen Yiyi are endless.

Of course, Comrade Shen Jianguo's consistent style is to accept all the praises his daughter has received. Of course, he didn't expect his daughter's "parachute" to be able to fly at the least. In fact, in his concept, parachutes were originally used by airborne troops to jump down from the sky, and he had never heard of a parachute that could fly from the ground. When his daughter said that he wanted to engage in such a thing, he didn't believe it in his heart, but under the reminder of Shen's mother, in order not to hurt his daughter's self-confidence, he still showed a fully supportive attitude. Now he can see his daughter's handmade drawings become real objects, and he is also very proud. Which of you children has such ability? But Master Shen is not stupid, he thought to himself that among these people who are now desperately praising their daughters, there may be anyone who will laugh at themselves if they see that their daughter's umbrella can't fly. So I can't get too carried away, I have to find a staircase for my daughter.

So after laughing for a while, Master Shen coughed again, and said to his daughter: "The results of your extracurricular group have come out, and it looks good." But don't think this thing can actually fly into the sky. The model of an extracurricular activity is different from something that can actually fly into the sky. I don't believe you see that there are experts here today, they know best. ”

Teacher Shen's original intention was to define the pile of things that Shen Yiyi had made up these days as the manual work of middle school students' extracurricular interest groups. Because if it is manual work, then Shen Yiyi and they can be regarded as overcompleting the task. As for what Shen Yiyi boasted to him about before, the sharp weapon that helped the First Division defeat the Ninth Division, Senior Colonel Shen had never thought about it. The reason why experts are mentioned at the end of the day is actually counting on two experts to round the field, and it is best to say some words in front, such as these things as extracurricular inventions and creations of middle school students, which should be mainly encouraged.

However, Master Shen thought very well, but the two old experts did not support it. After listening to Master Shen's speech, Old Man Xiao immediately had a different opinion: "Let me tell me." Shen Yiyi's research results are still very meaningful, but unfortunately this is not our official project, otherwise if the results are appraised, it will definitely fill the gap in China in the future. Although there has not yet been a verification test, that is, a flight test, the last test test, but the previous test on the test bench of the 606 Institute, it should be said that at least in terms of the power part, the design is very successful. ”

Old man Xiao Yizhan's public affirmation made many people not expect. Many people, including Master Shen, secretly thought that this old man really liked Shen Yiyi, and said good things for her so publicly. However, the words of the old man An Zhusheng next made them have new expectations for these iron bumps.

Although Old Man An was not very happy to attach to the oxtail of Old Man Xiao Yizhan, he still said truthfully: "We have tested the performance of this engine designed by Shen Yiyi, and it should be said that the results surprised us. I can say that at present, in China, there is no engine of the same type with better performance than this engine of this grade. ”

The speeches of two very prestigious old experts in a row affirmed Shen Yiyi's invention in this way, which made Master Shen wonder if his understanding of his daughter's game had deviated. Even when he looked at the engine and fan on the ground again, he looked at it with a new scrutinizing eye. Master Shen thought to himself, maybe, this toy of his daughter can really fly?

If he can really fly, the sensation that may be caused, as well as the evaluation of the two famous people in the aviation industry just now, Master Shen can't help but flutter in his heart. He suddenly turned his head and asked his daughter: "Yiyi, are you really going to test fly next...... Belch...... Paramotor? ”

Shen Yiyi nodded affirmatively. The reason why she wanted to complete the assembly of the paramotor today in advance was of course that she wanted to complete the test flight today. Because only the completed test flight can prove with the best results that my scientific research work has been a complete success. Of course, in addition to wanting to let the first division understand and learn to use this vehicle in advance, another factor is that she heard from the weather station that there will be a wave of cold air next week, that is, the coming of the spring cold.

The wind force required for paramotor takeoff is 2-3. Due to the limitation of its own power, the paramotor is not resistant to high winds. This means that if you want to do a test flight, today is the best choice. (To be continued......)
