Chapter 257

"After grandma's, I'll change it to LED light!" Liu Ruoxin is calm when she wants to jump. He looked at Xiang and said, "since you have so many plans in the future. I don't embarrass you either, as long as you can make ends meet. I don't mind making a small profit. I'll see the benefits at the end of this year. How about that? "

Xiang Qianjin sighed: "don't you want to go out and work alone? It's not right

"I've decided that I'm not going to quit. I'm going to expand my business." Liu Ruoxin looked at Xiang Qianjin and made Xiang Qianjin depressed. He nodded and said, "OK! It's up to you. "

Xiang Qianjin's wild imagination has brought Liu Ruoxin back.

Liu Ruoxin changed her mind. Now the key is that there are not enough people in her family. Liu Ruoxin found a rule that the women brought by Xiang Qianjin are all first-class. JK, needless to say, is better than her. Let's put it this way. Among all the women around Xiang Qianjin, JK's ability is the strongest. Liu Ruoxin thinks she can't match JK.

Then there is ye Qingwu, although she is a servant girl. But in fact, the ability is not inferior to their own. This woman is strong, too. Although Zhou Yuhan looks weak, his ability to handle affairs is also good, which often makes people marvel.

Even Zheng Miaomiao, who died, is a genius who can take charge of his own affairs!

The worst is XiuXiu, but XiuXiu is obedient. Xiang Qianjin can do whatever she wants, because she is obedient, so the management of Chuxiu group is also very good.

However, there is still a great shortage of such talents! Xiang Qianjin's business and Empire are really powerful.

The talent gap is too big. Liu Ruoxin really wants to open a palace draft for him.

Otherwise is really tired!

However, Xiang Qianjin is quite honest. He is the kind of person who looks for flowers and asks Liu. He'd rather be in the lab sometime. There's a little time for postgraduate entrance examination. Think about Xiang Jin's life. I suddenly feel so hard

Xiang Qianjin succeeded in closing Liu Ruoxin's heart. In fact, doing biological research also makes money. Fortunately, there are too many advanced technologies. After Liu Ruoxin handed over the LCD technology, she couldn't wait to get it. After Liu Ruoxin is pacified, Xiang Qianjin can finally study hard.

This time, the country asked him to develop UAVs. He also plans to further study in spacecraft. Now the best solution is to realize the production of ground electric propulsion technology UAV, because if the electric propulsion UAV is developed, then the electric propulsion spacecraft will have a way. If the engine technology is solved, this project can at least solve the needs of deep space exploration.

In the final analysis, the efficiency of using rockets is too low. Xiang Qian really doesn't look at this kind of technology, and it doesn't meet his needs at all.

The space shuttle is his dish, his love. In order to meet the needs of work and study, Xiang Qianjin ran the research and development of field commander of deionization Engine Research Institute.

Now the R & D institute's research and development of thrusters has reached the thrust level of 30 kg. It's a big breakthrough. However, the power load of the battery is too large, and the difficulty coefficient of the DC driving device is too large.

Item forward carefully checked the data, it seems that the battery direction is the problem. After he called the people from Changming palace. Xiang Qianjin said in a deep voice: "lithium batteries can't meet our needs."

"Mr. Xiang, what does it mean that lithium batteries can't meet the demand? I don't understand... "

"Literally, I can't accept that the capacity of the battery is not enough for the level we need."

"You mean..."

"R & D of new materials, R & D team. Yuhan, don't be lazy. The key to your research and development is graphene, a space grade graphene material. Didn't you find your breakthrough direction? You will start to work on new materials in the future. This is the direction of the test! "

"Batteries? What about graphene batteries? "

"Lithium batteries are OK for mobile phones. But when it comes to large-scale equipment, it's not enough. Graphene is a new kind of material which has been researched and developed in the world. Although it was found earlier, the preparation scheme was basically zero. It's just a concept, and there's no real experience in research and development. "

"The graphene battery..."

"Or lithium battery is a special technology that continues to improve from the direction of lithium battery. Our lithium iron phosphate technology has been greatly improved, and lithium titanate technology has also made a complete breakthrough. Now our battery technology can be very small. It's very difficult to give you the research and development direction this time. I have the technical materials written here for graphene technology. After copying, we will pass them around and watch them. If there is no problem, we will announce the development of graphene technology this month. Everything should be kept secret. "

"Yes, but in your opinion, it's still a lithium battery?""Yes, it's just graphene instead of graphite. Graphene is natural. Now we are mainly separating graphene from graphite. Graphene technology is hard to say, not hard to say. The direction of our breakthrough can be easily completed. At least for Huayan, where we are now. You are fully responsible for the project of Yuhan. Let's fight for this month. You can make the technology into a project, and then I want samples. How about that? "

Zhou Yuhan nodded and said, "good! Let's do research and development before the test? Not preparing for the exam? "

"Do you delay your study? This is the most solid thing to do. "

"What about English?" Zhou Yuhan asked.

Xiang Qianjin asked curiously, "you are a person who can curse foreigners in English. Do you want to tell me that you are afraid of English? Which of these subjects can't you do? Isn't the exam a minute for you? We are not graduation thesis, we are postgraduate entrance examination. If we are worried about this, let's not mix up. "

Zhou Yuhan said in a low voice: "yes, too! All right, then

Xiang Qianjin was in the office with Zhou Yuhan. When he wrote the plan, he began to tell Zhou Yuhan about the characteristics of graphene, the difficulties in preparation, and the advantages and disadvantages in use.

Zhou Yuhan surprised said: "graphene battery has so many advantages?"

"Of course, graphene batteries can be very small and have high capacity. Once graphene materials are broken through, solar panels and liquid crystal display technologies can also be broken through. You are the expert of new materials Xiang Qianjin wrote and said with one mind and two uses. It's no trouble at all. Zhou Yuhan whispered, "Oh! So... I'll come on! You can rest assured. "

Xiang Qianjin wrote a plan and began to tell Zhou Yuhan a little about graphene. In ten days, Xiang Qianjin made Zhou Yuhan a graphene expert. Of course, she is an excellent student of energy materials, so she is more diligent in learning super lithium batteries.

When Zhou Yuhan went to Changming palace, she began to take charge of the work and started the research and development process. She handled it completely according to Xiang Qianjin's arrangement, and because she understood it, she could start the research and development arrangement. In other words, new materials are not like other things, because the biggest problem of directional materials is wrong direction, so research and development is very difficult. But someone pointed out a way for you, what you should do and how to do it. Get the data, and the comparison data he gave. They just do experiments and produce materials according to the plan.

In this case, it is assumed that the battery is produced and the corresponding engine is made. Xiang Qianjin is now starting to research and develop the engine by connecting the converter directly to the engine. After ten days of research and development, I dare not.

Because 10 days less than 100 million, an average of 10 million per day burn.

What good man can afford to burn? Ten samples were burnt out in ten days. Burnt things are only materials, nothing else.

Xiang Qianjin sighed, and the thrust of 30 kg made Xiang Qianjin break through to three figures ten days later. It's a hundred kilos of thrust.

The big guys in the Institute are very happy, but Xiang Jin is not. One hundred million yuan was spent, and only one hundred kilograms of thrust was burned. It's really shameful to see the elder Jiang Dongfu. And let Liu Ruoxin know that he is here to do harm to money. He must be worried.

Xiang Qianjin sat in the laboratory, looked at the last engine and said, "at least we have to improve our technology. Ten days have been wasted."

"Xiang Zong, the thrust of 100 kg, we are already very good!"

Xiang Qianjin sighed: "this is a cow? Have you ever had the best pie? "

"But our technology is higher than that of foreign countries. I don't know how much!"

"I tell you, white hawk can do it now. So can their lab. It's not that we can figure it out. We've made a big breakthrough. This kind of engine started much earlier than us. People have tried it. Let me tell you, if the thrust is less than one ton, it's hard for us to say whether we have developed it? It's a shame, OK? "

"Mr. Xiang, are we lagging behind in R & D?"

"It's not backward, it's advanced, because our technology is really better than white eagle's. Now the key is that if the single thrust can reach one ton, we can make the engine into four parallel engines. The size must be fixed in this way, and then we can launch the thrust through four jets. Let's continue. I think we can optimize it again! The direction of the jet can be redistributed! "

Xiang Qianjin talks and points to the above things. As the last indicator, Xiang Qianjin intends to make a breakthrough. Now they are going to make something on the test bench. At present, Xiang Jin can carry out this kind of experiment at most three times. If he does it again, he will not be able to carry it. If this one doesn't work, we can only purchase materials for two more. Re assembly, that is to say, if there is a breakthrough development this time, there is at least momentum to go ahead. If there's no big break. I'm afraid to burn it.It doesn't make any difference to burn money! Ten million in ten minutes! More than 16000 per second on average!

After Xiang Qianjin checked the engine for the last time, he looked at the console very seriously and said, "turn it on!"

The ion engine ejects the ion stream, and the harsh noise can be heard when the engine moves forward. Looking at the data uploaded from the test bench, my heart is in my throat.

"100 kilos! 45 seconds! "

"150 kg!! 58 seconds! "

"Continue to increase output!" I'm biting my teeth and looking at the increasing data.

"300 kilos!" Xiang Qianjin looked at it stupidly, without saying a word, and his sweat flowed down his forehead.

"500 kg!"

"700 kilos!" There has been some agitation in the room. Many people can't help clapping their hands. They are all staring at the data sheet.

"890 kg!" This is a word out of the room people feel breathing stopped! No one dare to speak, the atmosphere dare not breathe!

"950kg! 1013 kg! "

"Hooray!" The people in the room suddenly burst into cheers, and everyone was shouting excitedly. Although the engine was still burned, the people in the room were ecstatic, and even some people cried. They made it! As long as there is the first time, there can be a second time, and the thrust of 1000 kg can be maintained normally! The engine's done
