Chapter 339

Xiang Qianjin is really convinced. Can she think of this method of metal hydrogen? Solid metal hydrogen fuel cell, this project has never thought of, metal hydrogen in the sealed high pressure cabin as a high-end fuel cell fuel is really not an ordinary cow! Metal hydrogen fuel cell is obviously not suitable for miniaturization as mobile phone battery. Now lithium iron phosphate battery is enough, and graphene battery with lithium phosphate will be enough later.

After all, it's meaningless to have enough batteries. Smart phones are the key. As long as the problem of fast charging is solved, there's no need to stop charging for a few weeks. To solve the problem of wireless charging technology, you can basically play as you like.

Xiang Qianjin really didn't expect that Du Qingyi's eyes were so fierce and in tune with himself. He stopped Du Qingyi into the laboratory with a smile and said, "your plan is very good. If such a battery is equipped with graphene technology, charged in advance, and then combined with the conversion of fuel cells, it can be basically guaranteed! It's up in the sky

"Yes, and as long as the packaging technology is good enough, we can use a little heart in the packaging. Metal hydrogen filling can be as simple as a bullet. I personally recommend using the bullet mode. The metal hydrogen will be loaded into the high-pressure sealed steel cylinder. After filling, the metal hydrogen in the cylinder will be directly released in the fuel bunker for conversion, and it will be continuously filled like a bullet. "

Xiang Qianjin then said, "yes, put it in. There is a mechanism behind it. It pushes the metal hydrogen directly into the fuel bunker with a striker, and then throws the cartridge case out!

Zhou Yuhan said in a low voice: "I'll go, it's really powerful! Can you think of it all? "

Du Qingyi said with a smile: "what we need is the technology of automatic ammunition filling machine and the principle of some guns. We will make magic changes again!"

Xiang Qianjin held his chin and said, "well, there is no problem with this idea in theory. What we need to do now is to make these shells, which need composite materials, and the impact pin should not have too much force, and it should be suitable and not detonate."

"And it's definitely not small!"

"I guess it'll be one or two meters long anyway?"

"Er... What do you call a two meter long thing a needle?" Zhou Yuhan was really speechless. Xiang Qianjin said with a smile, "there will be something more speechless for you in the future."

Three people went into the lab inside, and the lab was still doing all kinds of experiments at home. Xiang Qianjin said in a low voice: "what we are doing now is the research and development of UAV, which is to refit the bass engine into electric propulsion. I'm really upset now, but you remind me that we can use aircraft to test and hydrogen to make fuel cells first. I think this kind of scheme should be able to be used on UAVs! "

Du Qingyi said in a low voice, "well, that's true. Hydrogen is light. It can make the plane bigger. Although it's heavy, it's not heavy. Either liquid hydrogen or liquid oxygen can be used. In general, the conversion output power of fuel cell technology is not low. If we want to use fuel cell technology in advance, it is a good way to use UAV. After all, the situation is very similar, much better than car! "

Xiang Qianjin thought about it, then nodded and said, "you're really right, if you use this technology."

When Du Qingyi said this, Xiang Qianjin quickly asked people to take notes. He looked at Du Qingyi and said, "next, let's do the technology with me. Let's try to work out the scheme today. You're right. We can start the test with liquid hydrogen."

Du Qingyi said in a low voice, "is this the beginning? We don't have the knowledge yet? There is no technical verification or discussion, just the two of us? "

"Ha ha, the technologies you mentioned are all ready-made here. We just need to take out this technology and combine it together. The key is the train of thought. Let's put it this way. As long as you tell me, I have most of them. Unless the technology is useless. Otherwise, I do have them all here. " Xiang Jin confidently pointed to his head and said. Du Qingyi thought about it and said, "OK! Forget, you'll hang up! "

Zhou Yuhan some jealous said: "what about me?"

"Of course, it's to help us coordinate the transportation of materials and arrange the experiment. How can we do without you?"

Zhou Yuhan snorted, and then said, "make a list of what you need, and I'll allocate it for you."

Xiang Qianjin put his arms around her waist and said, "don't worry about this. We are in the exploration stage now. We have to consider the scheme ourselves. The technology on the shelf is ready-made, but the assembly is also very brain consuming!"

Xiang Qianjin is embracing her left and right when Anna comes in from the door and hits her right. She stares at Du Qingyi and says, "who is she?"

"Oh, to introduce you, this is Du Qingyi."

"Anna blinked and said," Oh! That... Du Qingyi? Ha ha, is that what I brought? How powerful is that? "After Anna finished, she put a lot of things on the table and said, "the simulation data of UAV are all taken out. There are 60 kinds of supercomputing simulation results and feasible schemes, and basically each one can meet the requirements. It's up to you to decide how to choose. In addition, the military is worried. We were disgusted by white hawk before, and the things of the year before last still can't be forgotten by the Chinese people.

Xiang Qian looked at the calendar on the wall. It's 2001

He said in a low voice: "I can understand that the troops have already cursed, but our national strength is weak and we can only bear it. But we still need time for UAVs. Now we can only make do with one, which can't solve the problem. Personally, I think it's time for us to take action. "

"The problem is that what the white hawks said infuriated the military. They think that the sea and air area is just the way they want to go. The coastal air defense area in China is their back garden. They can come as they want!"

Hearing this, Xiang Qianjin said angrily, "who said that?"

"A general of the air force said that he always looked down on us."

Xiang Qianjin said with a black face: "sooner or later, break their wings! Talk hard? You wait for me to give him some color to see see, isn't bull force? I'll give you some stimulation! "

Xiang Qianjin is a man who can do what he says. He and Du Qingyi discussed the fuel cell issue. By the way, he also started the research and development of a new generation of jamming equipment at the changminggong Research Institute. Raw materials are taken directly from all directions. It's the first time we've worked together. After getting the raw materials of semiconductor, the R & D Progress of Xiang Jin is not slow. It's been a week. And the materials have entered the sample workshop! The design drawings and plans have come down.

For the rest, Xiang Jin still has to go to Honggang. This time, he plans to discuss with Liang Bin and directly supply a batch of materials to the army to see the feasibility. After all, material safety still needs to be achieved. This thing can't be controlled by foreign countries. Once it's under control... It's hard.

After the transcripts come down, we have to go to see them. We have to see if we can pass the exam.

Du Qingyi really changed a part-time quota, and the school opened an extra quota for her. But if you can get it, it's her.

Part time as long as four, the exam is to rely on with full-time, if you want to test, it must be in the candidates for part-time people to get the top four. This is not difficult for Du Qingyi. When she came to the school gate, as soon as she got out of the car, Du Qingyi saw Pei Yueying coming. Du Qingyi looked at Pei Yueying and said coldly, "ha ha? You're not finished yet? "

"I'm not looking for you, you understand!"

Du Qingyi looks at Pei Yueying curiously. She looks at Xiang Qianjin and says, "today I'll see what else you have to say? Don't you think you're good when you're cruel? "

"Yes? I've always been a bull. I'm not convinced? You hit me? " Xiang said with a smile.

Pei Yueying held her shoulder and rolled her eyes and said, "you have a dream! I'll make a bet with you. Do you dare? "

"What's the bet?" Xiang Qian asked curiously.

Pei Yueying's voice is not small. Many people stop to look at them after they hear it. They all want to see what's going on and whether there is any excitement.

Pei Yueying hugged her shoulder and said, "if we have a high score, the low one will worship the high one as our teacher."

"Tut, you're not dead. Do you want me to be your master? Go on dreaming

"You dare not?" Pei Yueying hummed coldly.

Xiang Qianjin said with a smile: "ha ha? I don't dare. I don't think it's interesting! "

Pei Yueying said with a smile: "good! Let's have something interesting. Losers should pay homage to their teachers, three times and nine times! If you want to kowtow in front of the list in front of everyone, do you dare? "

"Who is the best? OK, I'll take it! "
