"I'll go, sister Weng. Don't scare me?"

Weng Weiyi showed Liu Yan the circuit sketch drawn by Xiang Qianjin. She calmly asked, "you are a top student in Massachusetts. Where have you seen this thing?"

"I'll be good! This is the electronic control design! Amazing! What do you think? " Liu Yan asked with a circuit sketch in surprise. However, Xiang Qianjin was completely immersed in thinking and didn't pay attention to his meaning.

Item forward is to think about how to deal with this scheme. Item forward not only has rich experience, but also has a lot of technology in the black box. The storage capacity of the technology is amazing.

Although technology is here, it can't be used at will. According to the current ability and technical level, as well as the actual mastering ability and other conditions, we need to find a solution that meets the current situation from multiple angles.

Xiang Qianjin kept thinking, and his pen couldn't help sketching. He kept sketching. When he came back, the three people looked at him like ghosts. Xiang Qianjin was startled. He quickly said, "do you three dare?"

"What are you doing?" Three people looking at item to advance to say.

The table was full of sketches. Xiang Qianjin said with a smile: "sorry, I didn't control it well. I just want to do something. It's not under control. What do you think now? Is there a direction for people? " Weng Weiyi asked directly. Xiang Qianjin sighed, "it's not so easy. Let's take our time."

Zheng Miao said with a smile: "it doesn't matter, if you have a detailed plan, you can let me help you draw."

"Don't tell me. I have an idea. I have a new idea. Instead of being compatible, we should have two types of ion engines, two models, and no usage."

"Do you mean that the design of the engine should be done in different ways according to its location?" Weng Weiyi asked suspiciously.

"Ion jet engine is different from turbofan engine. It can only be used for a while. The key is orbit change and fine-tuning. Since we can't do a good job in fine-tuning, we can also use two schemes! In some cases, such a large thrust is needed, and the nozzle steering is not as stable as direct directional injection. Once the special nozzle fails, the satellite will be in trouble. However, we have changed it to directional, and designed some smaller injectors according to the attitude of the satellite, which will reduce the weight on the whole, The more functions the injector has, the larger and more complex the volume will be. Don't think about it! Our ejector mechanism can be smaller. In this way, the ejector can be much simpler. We just need to add more "insurance". Is that right? "

Weng Weiyi said in a low voice: "what you said is not wrong. It's really a good idea! But the problem is that if our engine shrinks, it's not as simple as shrinking. If it shrinks, the thrust may not be able to keep up

"In another way, we'll use other solutions, some more reliable solutions. Originally, we planned to make two kinds of engines, one is the orbital propulsion device, and the other is the orbital fine-tuning engine. Fine tuning engine needs small thrust, but it needs stability and long life. Because the starting times of this kind of engine will be far more than the times of driving the engine, we use small ones to reduce the times of using the main engine, reduce the load of the battery, and reduce the possibility of problems. " Xiang Qianjin says here, Liu Yan says in a low voice: "is this really the last way?"

Weng Weiyi said in a low voice: "I have thought about it, but we can't be that small..."

"That's why I'm here!"

"This kind of small engine itself needs a lot of thrust. We don't need much thrust, so the manufacturing method will be much easier and the production will be very fast."

Xiang Qianjin said that, Weng Weiyi nodded and said, "OK, that's it. Let's make a sample first! "

Xiang Qianjin nodded and said: "the key to this thing is simple, simple can guarantee strong patience, but also fine, although their fine adjustment is only a small push, it can make the satellite maintain the orbit height! Increase the life of the satellite! And full open also can carry on the fast maneuver to change the orbit! Although it's a small thing, it's not a complicated thing, but the requirements here are very direct. "

"Well, let's start first." Weng Weiyi is also a workaholic. Her habit of working with Xiang Jinjin is really the same. Zheng Miao asked curiously, "sister Weng, can this ion engine send the satellite directly to heaven?"

"It's impossible. We can't make such a high-power engine, materials, technology and energy yet."

"To put it bluntly, the thrust of these engines is not as high as that of some toys. But the point is that our engines use electricity, and we don't need to store fuel or inject gas. It's small, it can take less weight and add more equipment to the satelliteZheng Miaomiao sighed: "just such a small engine, so many bends in it?"

"This little thing is really so many things. If we do a good job in this aspect, we can do better in the aspect of satellite orbit change. The key is that the engine can be smaller. That's the key. If the engine thrust can be greater, we can go further! I'm not sure when I'm going to play on Mars and Saturn! " Weng Weiyi said with a smile. Xiang Qianjin nodded and said, "well, it's true."

Zheng Miaomiao said in a low voice: "it's really a great project. So, can I take part in such an important project again? After I met a senior, my life was good! "

Xiang Qianjin said with a smile, "then don't be idle. Since you are doing a new design, you are indispensable for the design."

"It's on me!" Zheng Miaomiao patted his chest and said confidently.

Xiang Qianjin didn't want to waste time, so he tried to solve the immediate problems as much as possible. Although it was simplified, it left enough space for future upgrading. The size of the whole engine is really small, and several of them have been arranged. Weng Weiyi has seen a lot of schemes for plasma engine. It's the first time that he has seen Xiang Qianjin's scheme. Although everyone's principles are the same, the design of the scheme is different. Xiang Qianjin's scheme design can be large or small, but there are still some deficiencies in the material aspect when it becomes large. But once the material can make a breakthrough, the scheme can definitely pass. "

All electric propulsion spacecraft... Weng Weiyi thinks that science fiction

If all electric propulsion, it means that this kind of aircraft can be reused for many times at least! This small engine forward, but for the future hidden infinite possibilities!

The time plan for the whole night was put forward, not to mention the detailed drawings. It has to be said that Zheng Miaomiao's drawing ability is really powerful, and her best is the accuracy of the drawing, which is really a talent.

Liu Yan took the drawing and went straight to the headquarters. Xiang Qianjin, Weng Weiyi and Zheng Miaomiao stayed behind and continued to change the circuit. In a word, their plan was a double plan in parallel. They also agreed to the design and took it to the manufacturer to produce samples. During this period of time, they will go all out to improve the electronic control scheme of the orbital propulsion engine.

Because Xiang Qianjin did not preside over it from the beginning, so the details can only be dealt with a little bit. I tried again and again and started again. Finally, on the third day, the electronic control was improved

Weng Weiyi was very excited. She really didn't expect that the project was advancing so fast after Xiang Jin came.

No one knows what happened here at all. Xiang Qianjin doesn't intend to talk about it.

Is he really a young man? Why is he so indifferent to everything? What does he want? Weng Weiyi really didn't understand the item and moved on. Isn't this guy a real alien? Otherwise, how could director Zhou believe him so much? Weng Weiyi was not optimistic at all. As a result, Xiang Qianjin brought her to the present situation, and the result should be available soon. Weng Weiyi looks at Xiang Qianjin. She thinks about things in her mind. When she is distracted, Xiang Qianjin pulls Weng Weiyi nervously and says, "go back quickly!"

"Well?" Weng Weiyi asked in surprise.

"I said go back! There are wolves Xiang Qianjin nervously pushed Weng Weiyi. Then he picked up the pistol in the drawer. Then he went to the door and said, "I'll see the situation. You can go back to the room as soon as possible. Don't open the door!"
