Chapter 57

Weng Weiyi looked at Xiang Qianjin in surprise. Xiang Qianjin said with a smile: "this is really your plan, not mine. I just reversely deduced your scheme design, and then reversely deduced what the ultimate situation of this design is, but some details of your here and here are deviated, and the deviated position is in the design of electronic control, which is really not up to standard. "

Weng Weiyi looked at Xiang Qian suspiciously and then asked, "these places have adopted similar designs from abroad."

"Don't be superstitious about foreign technology. They are doing it, but no one has mass-produced the ion engine so far. That is to say, no one has explored it to the present level. Now you are on the starting line with everyone. The key points of the ion engine are the thrust weight ratio of the engine, Now basically, it can't meet our requirements at all. What's more, your original design was to adopt the design of all electric propulsion, but later you have to change to chemical propulsion. It doesn't take too much for the satellite to push in orbit. 0.23 grams of thrust can push about a ton of weight. We must make clear what our initial core vision is. "

Weng Weiyi said in a deep voice: "using its excellent specific impulse and controllable specific impulse to realize space orbit transfer technology, maintain orbit height, or reduce orbit height..."

Xiang Qianjin snapped his fingers and said, "yes, this kind of engine will reduce the weight of the vehicle a lot, and increase the weight of the equipment and the weight of the battery. With more batteries, its working power can be increased. With more power, the equipment will be more complex. In terms of electronic control, we must remember the simplicity under the premise that we can do more detailed actions. The simpler, the more simplified. The lower the probability of electronic failure. We use the standards and requirements of these foundations to design this scheme, and then we can boldly do some optimization design. "

Weng Weiyi is confused. To be honest, he has seen many experts come here, and some foreign experts have never been so direct as Xiang Qianjin. And he seems to really understand the plasma propulsion technology, and the technology he knows should be very mature, otherwise he would not draw inferences from one instance.

Weng Weiyi thought about it and then said, "do you mean to simplify the electronic control and go for the core functions?"

"Yes, you don't want the functions that you can't want. The functions that you have to want must guarantee the safety factor."

Weng Weiyi nodded, she whispered: "then you have a plan in mind?"

"There is no problem with your promotion. Don't change the design. I saw that when you changed the design and changed the plan to 1187, it was the closest to success. You have misjudged the engine and your willingness to make mistakes, which leads you further and further away from success. This is all the information at that time, you see! "

Xiang Qianjin took out the data, pointed to the above data, and then asked: "such data, do you think it is the engine problem? This is obviously the problem of electronic control. The loss of the signal doesn't explain the problem? "

"Come on, let's start with this plan and try to redesign it in three days." Xiang Qianjin said that and laughed. Weng Weiyi also showed a faint smile, she nodded and said: "what is the core of your experiment?"

"Reasoning, this time only test remote ignition, reached the reasoning peak in three seconds."

"Well, I'm ready to go now."

"Well? Sister Weng. " Xiang Qianjin subconsciously pulled Weng Weiyi for a moment, but he accidentally pulled Weng Weiyi's hand

Weng Weiyi blushed. She coughed, then quickly drew back her hand and said, "what's the matter?"

"Well, you'll have a rest today. I'll work overtime in the evening. I'll give you a report on the materials and experimental procedures tomorrow morning."

Weng Weiyi was stunned and asked, "are you going to work overtime today“

"Let's make sure my thinking is right. You don't think it's a problem. Liu Yan is complaining to me. He's going to collapse. You have to finish the task quickly. What's the matter in the Gobi? "

Weng Weiyi thought about it and then said, "I'm with you. I still remember all the experimental data. Aren't you used to being dictated? "

Xiang Qianjin said: "er... It's bad for you to stay up late. I'm young."

Weng Weiyi said with a serious face: "less nonsense, let's start now!"

Weng Weiyi and Xiang Qianjin are in the office. They start over from the past experimental plan. All night, Xiang Qianjin and Weng Weiyi have never had a close eye at all. They actually worked out the specific experimental plan in one night. And after taking out the experiment plan, Weng Weiyi directly threw things to Liu Yan and said, "arrange the experiment immediately, arrange the car, and we'll go now."

Liu Yan looked at Weng Weiyi and Xiang Qianjin. He was surprised and said: "experiment?! When did it happen! Haven't we started the experiment yet? Well, what a night... Did you two work overtime for one night? My mom... Good guy, another workaholic! " Liu Yan looked at the two people with a muddled face. Weng Weiyi glared at Liu Yan and said, "there's so much nonsense! GoLiu Yan quickly takes the experimental plan to arrange, Xiang Qianjin and Weng Weiyi two people are tacit understanding, get on the car, and then two people sit in the back to make up for sleep. After all, there was no one in the night. The driver Lao Wang looked at the two people curiously and said, "what's the situation between the two?"

"Workaholic meets workaholic, understand? I saw two immortals! Uncle Wang, why don't you introduce that widow to me? I think I'm going to be a bachelor! " Liu Yan said bitterly.

The driver couldn't help laughing and said: "you know a lot. If the student child can really let director Weng work overtime together, it means you have a play. I see. Maybe you're going to leave soon. "

Liu Yan asked suspiciously: "really?"

"Oh, my old Wang is very accurate in judging people. He is not convinced that we can bet on a bowl of cold noodles!"

"Yes! Let's make up our mind, Dadao cold powder! Oh, if I can succeed, I'll be so happy! " Liu Yan rubbed his hands and said with an excited smile.

Just as the car went out, another car stopped at the door. In order to catch up with the progress of the test, all the cars left directly, and the new car followed directly.

Xiang Qianjin sits in the car and sleeps all the way to the place. After arriving at the test site, Xiang Qianjin is awakened by Liu Yan. He wants to get close to Liu Yan, rubs his eyes and says, "Oh, ha! After this experiment, you should have a good sleep. "

As soon as Xiang Qianjin pushed the door and got off the car, he saw a figure jumping over and hugging Xiang Qianjin enthusiastically. Xiang Qianjin is confused. Who is this? So enthusiastic? And the touch from the chest, it's a woman! As soon as he bowed his head, Xiang Qianjin called out: "Oh! Miao Miao? Why are you

"Hey, hey, isn't it surprising? I've been chasing you all the way. " Zheng Miaomiao looked at Xiang Qianjin with a smile. Xiang Qianjin said suspiciously, "my assistant is you?"

"Yes, that's me!" Zheng Miaomiao smiles and looks at Xiang Jin. When Liu Yan gets out of the car and sees Zheng Miaomiao, his eyes almost fall out.

Liu Yan surprised said: "my God, I see fairy daughter?"

Zheng Miaomiao said with a sweet smile: "Hello, I am Xiang Qianjin's assistant and my favorite primary school sister. My name is Zheng Miaomiao

Weng Weiyi looked at Zheng Miaomiao in surprise and asked, "Miaomiao? Why are you

"Oh, sister Weng! You're here, too! I said, "why did they call me here?" Zheng Miao said excitedly.

Weng Weiyi didn't turn around for a while. Zheng Miaomiao is the granddaughter of Zheng Qiaomin. That's the treasure of the Zheng family! Why did you get it here? It's not like eating bear's heart and leopard's gall? Mr. Zheng doesn't work hard for him?

Zheng Miaomiao's face is excited, her eyes are almost all on Xiang Qianjin, others will know what's going on!

Xiang Qianjin said with a smile: "yes, director Zhou brought you this humanoid plotter, which can be regarded as solving a big problem for me. But what do you do in class? "

"It's not bad if I don't pass the exam! I can take part in the actual scientific research projects, which belong to our family
