The day after returning from sightseeing in the city, Shen Yiyi grabbed Luo Yu and wanted to have a meeting. Of course, Ao Tianyang, who was in the same room with Luo Yu, saw that Shen Yiyi was going to be alone with Luo Yu and the others, and he was immediately unwilling to make room for the two of them, and he must have squeezed into the small circle of these two.

Luo Yu was too excited to play the day before, and he had to sleep lazy, and he was forced by Shen Yiyi to get up early in the morning and not let him sleep, and the resentment in his heart was mentioned. Of course, his complaints had just begun, and he was resolutely suppressed by Shen Yiyi one by one. Moreover, Ao Tianyang, this kid, shamefully acted as an accomplice of the fascists.

However, Shen Yiyi has his own panacea for his lazy disease. She just said a noun in front of Luo Yu gently, and suddenly mobilized Luo Yu's Xingzi.

"Really? Are you really going to make another flying machine? Luo Yu's flickering eyes fully exposed his obsession with flying machines as a son of an aviation man.

Shen Yi nodded: "How is it?" Do you want to do it together? ”

Luo Yu sat up straight all of a sudden: "Of course we have to do it together." I said Shen Yiyi, you can't throw us down. We helped you with that paramotor last time. If you want to make something new this time, we'll be able to help too. Tell me, what are you going to do this time? ”

Shen Yiyi saw that his enthusiasm was aroused, so he really didn't say anything. She pointed to the bathroom and said to Luo Yu: "You, wash up first and tidy up your clothes, so as not to be criticized by the teacher for our too revealing conversation." ”

Luo Yu noticed that he was still wearing big pants, and hurriedly got back into the quilt. looked at Shen Yiyi's back and shouted at her: "Hey, can you be a little girl-conscious?" How can you run to the boys' dormitory like this, and you are not ashamed! ”

Shen Yiyi ran back to his room and took a few drawings that he had taken time out of his room to draw in the past few days, and put them on the coffee table in his room after tidying them up. Shen Yiyi, as the only girl in the team, still enjoys preferential treatment in accommodation. The boys are in a room for two or three people. But of course it was Shen Yiyi's turn to share a room with the boys, so she was assigned a room by herself. If we really want to discuss a new plan today, her room is relatively more suitable.

It was only a long time before the doorbell rang. After Shen Yiyi opened the door one by one, the two big boys were already standing at the door neatly dressed.

Luo Yu saw at a glance a pile of drawings that Shen Yiyi had laid out on another empty bed. He couldn't wait to walk over to the bed, pick up the drawings and look at them.

Shen Yi leaned sideways. After letting Ao Tianyang also enter the house, he closed the door.

Ao Tianyang moved a chair to the side of the bed where the drawings were placed and sat down. Unlike Luo Yu, who lives in the Engineer's house, he basically has no training in the spatial imagination necessary to see three views. That's why smart people like him don't go to that pile of drawings. He's still playing his biggest hobby in a while. So Shen Yiyi had to endure a pair of recourse eyes that didn't leave her for a moment.

Luo Yu had already assembled the things on those drawings in his mind at this time. He looked through the pile of lines on the drawings and found that he seemed to see a strange plane that he had never seen before.

He raised his head and looked at Shen Yiyi with some confusion: "Is this a model airplane?" What kind of plane is this? I don't think I've ever seen it, huh? Also, is there no cockpit on this plane? ”

Shen Yiyi was not surprised that Luo Yu was able to read the picture in such a quick time. In fact, the reason why she decided to pull Luo Yu into her plan was because she preferred to deal with smart people and understanding people. In fact, she wants to do more and more things in the future, and it is impossible for her to do everything by herself. Bringing in some capable like-minded partners is also reducing their own burden. Let your success come sooner.

"Yes, of course you haven't seen a plane like this. And there really is no cockpit on this plane. Because this is simply a drone. Shen Yiyi gave his answer very calmly. And this answer made Luo Yu a little incredible.

"No, Shen Yiyi, when did you start playing model airplanes? It's boring. I thought you were going to do something the same as a paramotor this time, and you could get people to the sky, but it turns out that you turned around and went to do a model airplane for middle school students. Then you still let us help you, isn't that overkill? You must know that there are a lot of model aircraft teams in the Shaoke Station. ”

Shen Yiyi looked at Luo Yu's nagging amusedly. She looked at the drawings again: "You take a closer look at the dimensions on the drawing, and the title bar below should also take a closer look." Look at what this model airplane is. ”

Luo Yu saw Shen Yiyi say this. I went back and looked at the drawings again. Just now, he just focused on assembling these components in his brain, and he really didn't pay attention to the size or anything. But just look at it. Luo Yu's eyes couldn't help but widen, and he looked at Shen Yiyi in surprise: "What? This model has five hundred kilograms? ”

Shen Yiyi nodded proudly: "Yes, it's five hundred kilograms, and the load should be more than one ton." ”

"Wouldn't it? What's the use of you making something so heavy? This kind of thing is just a large model airplane, is it necessary to make it so big? Luo Yu said with some unacceptability.

Shen Yiyi had actually expected Luo Yu to say this. The aircraft in the concept of Chinese aviation people in this era should be that kind of fighter or transport aircraft. In short, they are all aircraft that are controlled by people on airplanes. And what she's going to do this time is not that kind of thing at all. What she wants to do is Shen Yiyi's version of "MQ-1".

It was this year that the US General Atomics Company successfully made its first flight for the first time after receiving a contract from the US Department of Defense of the United States. And although the US imperialists have built such a prototype, even they themselves have not foreseen the role of this kind of aircraft in various battlefields in the future. And we, the People's Liberation Army, who have always adopted the tactics of following US imperialism, will naturally not realize that it is an important part of modern combat power. Or as an important part of asymmetric strikes, unmanned aerial vehicles will be an important breakthrough to change the battlefield situation in the future.

In fact, there is a reason why unmanned aircraft have not been taken seriously in this era. Although there are no too difficult technical difficulties in aerodynamics and aerodynamics, in terms of control and communication, the technology of this era still has a long way to go to meet the requirements of unmanned aircraft. It is precisely for this reason that the United States will not formally turn unmanned aircraft into an army until the 21 st century has developed its microelectronics and communication technology to a certain extent, and it has played a role as a surprise force in the projection of force for its global hegemony.

Of course, what Shen Yiyi is currently planning is not the final version of "Global Hawk". In fact, she did anticipate that it would be impossible for her to have sensors and controllers that would be as good as those of the future. But she didn't say that she was completely hot-headed and made this decision with a pat on the head. Compared with jet fighters, the heart disease problem is heavily dependent on the development of basic industry, which can not be solved overnight, and the engine of the UAV "Predator" is a piston engine, which is much lower than the requirements for materials. In addition, the bosses of several authoritarian model aircraft that she had contacted in her previous life talked to her about the key points of the production of the overly high imitation "Global Hawk" model aircraft, and she was familiar with the flight performance of this aircraft. Coupled with some of the operations she planned for the next time, Shen Yiyi fully believed that she would be able to develop a new drone whose performance was not inferior to that of the "Global Hawk".

Regarding Luo Yu's question, Shen Yiyi was not ready to answer immediately. She only emphasized her determination to prepare for the "big model aircraft" with an affirmative tone, and at the same time told Luo Yu that she would either shut up and listen to her joining the team, or just walk away and stop thinking about researching new aircraft with herself in the future. Luo Yu was threatened by her like this, so he had to obediently obey the order, and didn't dare to say anything more.

In fact, the task assigned to Luo Yu by Shen Yiyi is still similar to that in the paramotor task, mainly some optimization and calculation of the envelope curve. Shen Yiyi predicts that there is still a gap between us and the United States in terms of engine technology. Although the Predator uses a piston engine, it has the same "thrust-to-weight ratio" problem as the jet engine. Our engine is estimated to have a lower thrust-to-weight ratio than the Predator, so it is even more necessary to compensate for it in terms of aerodynamic shape. In this regard, because he has contributed a set of formulas for calculation before, Shen Yiyi believes that the friends who have been trained in paramotor design will be able to hand in brilliant answers.

As for Ao Tianyang, now that he has taken the initiative to ask to join his drone team, Shen Yiyi will not let him just be a spectator. Ao Tianyang was very interested in Shen Yiyi's formulas before, and now there is another opportunity for him to try out and familiarize himself. Shen Yiyi believes that as a boy with science expertise, Ao Tianyang should not let himself down.

Just do it, holding a calculator in one hand and scratch paper in the other, the three of them started the first trial calculation of Shen Yiyi's drone in Shen Yiyi's room.

None of the two people in the room would have thought that they would be led by Shen Yiyi to open a new chapter in the army's new generation of killer weapons, and alarm the US imperialists in the near future. (To be continued......)
