Li Zhongting asked with some concern, "Is this thing mature?"

Chang Yanji explained: "Our vitamin support fluid is very rich in oxygen, even ordinary people can breathe directly in the liquid after an hour or two of adaptation, and during the breathing process, the vitamin fluid will fill the lungs and then fill the organs in turn. ”

"You've done human testing?" Zhao Hongxing asked suddenly.

"Forehead......" Chang Yanji looked at Zhao Hongxing, and then at Huang Haojie.

He doesn't know how to say it, this question is really difficult to answer, did I say that I used the boss as a guinea pig, I don't know if I will be killed if I say it?

Zhao Hongxing looked at Chang Yanji, who was spitting and spitting, thinking that the Life Research Institute was conducting secret human experiments, and suddenly asked with an ugly face:

"Is there anything unspeakable about Director Chang?"

Huang Haojie had to speak: "This question, let me explain, the vitamin liquid has indeed been applied to the human body. ”

"What? This ......" everyone at the scene was in an uproar, after all, human experiments are a taboo.

"I was the one who used the vitamin fixion at the time, and the reason why I used the vitamin was because I had a little sudden problem in my body." Huang Haojie can only tell some of the situation, so as not to let these guys think wildly.

"The experimenter turned out to be the boss......"

"It's too messy."

"In case something goes wrong......"

Huang Haojie stopped everyone from saying: "Ahem! At that time, I had to do it, and I took the initiative to ask for the use of life sustaining liquid, okay! Don't talk about it again. ”

Everyone looked at each other, and they could only say: You are really a ruthless person, a person who dares to experiment with yourself, after all, it really takes a lot of courage and self-confidence.

Huang Haojie motioned to Chang Yanji to continue.

Chang Yanji hurriedly gave everyone popular science:

Specifically, it is to inject the life-sustaining fluid into the life support chamber and completely immerse the human body in a liquid environment, including the lungs, respiratory tract and other human organs.

This fluid should be able to directly supply oxygen to the body, and under the condition of controlling the osmotic pressure, the body's body fluids and cells will merge with the biosustaining fluid.

This method fills the gap between the human body and the life support chamber, as well as the gap between the human body itself, to homogenize the mass distribution and optimize the force structure.

Since the liquid is difficult to be compressed, this can greatly reduce the deformation of human tissues under high acceleration, which can greatly improve the body's tolerance for high acceleration. ”

After finishing speaking, Chang Yanji clicked on the holographic projection display again and sent some test reports to everyone present.

"This report is our life research institute, for the test report of the vitamin fluid, specifically how much acceleration the cells will not break due to precipitation, we used the centrifugal separation method in biology to test.

The maximum speed of the centrifuge of the Institute of Life is 5500rpm, the maximum relative centrifugal force is 5310g, and the rotor radius of the centrifuge is calculated according to the formula (5500*2*PI/60)^2=5310*g/R.

Usually centrifugation at 1000~1500rpm for 20 minutes to collect viable cells, we use 1000rpm to test.

(1000*2*PI/60)^2=RCF*g/R, the relative centrifugal force RCF=174G.

That is to say, under the acceleration of 174G for 20 minutes, the cell did not rupture, considering that the human body is a whole, not a loose cell, the resistance to acceleration should be higher. ”

Everyone was looking carefully at the test report in front of them.

The habit of careful planning in the space bureau made Li Zhongting involuntarily ask a question: "How big is the life support warehouse?" Or what is the minimum that can be done?"

"The life support chamber we used in the experiment is 2.4 meters high, 1.2 meters long and wide, and after injecting the life support solution, the overall weight is about 3.4 tons, and it should not be possible to shrink it."

"Why?"

"The main thing is that it is necessary to install real-time monitoring equipment and life-sustaining equipment, which cannot be compressed, and the injection amount of life-sustaining liquid is also strictly calculated."

"3.4 tons, this living chamber is a bit heavy!" Li Zhongting's real spacecraft are all worth a lot, and every gram of weight must be carefully calculated.

"Maybe 3.4 tons is not enough, the life support warehouse also needs an external circulation system, and this plus up, it may take about 4 tons."

Academician Ma interjected: "Maybe 4 tons is not necessarily possible, after all, the acceleration that our projection spacecraft needs to withstand is very fast, and the structure of the life support bin needs to be strengthened, I estimate that a life support bin is about 5 tons!" ”

"5 tons is 5 tons! We can't subtract astronauts' lives. Huang Haojie made a decision.

"Let me ask a question!" Li Xiang also stood up and said, "Under the huge acceleration, will the osmotic pressure of the life sustaining fluid and the human body be unbalanced?"

Chang Yanji pressed his temples, and he hadn't thought about this question before:

"It's possible, but if the acceleration doesn't last too long, and the osmotic pressure fluctuates within 5%, it shouldn't be a big problem."

"We can't figure out why we can't figure out this problem behind closed doors here." After Huang Haojie finished speaking, he thought for a while and asked Zhao Hongxing:

"Mr. Zhao pointed out that you should also have astronauts' anti-load research!"

Zhao Hongxing nodded: "Yes!" ”

"So be it! Since the Institute of Life Sciences and the relevant research institutions of the Space Agency have cooperated in the research and development of a life support warehouse that can protect astronauts, Mr. Zhao pointed out that there is no problem, right?"

"No problem!"

"On the other side, after our projection spacecraft came out, we pulled the life support chamber to the spacecraft and conducted animal testing, and only when we actually tested it could we see if there was a problem."

"I agree!" Academician Ma nodded.

"This is really a test that must be done." Chang Yanji agreed.

"Okay, let's settle it like that!" Li Zhongting also agreed.

Others agreed with this plan.

Seeing that everyone had no opinions, Huang Haojie made a decision: "Well, the problem of human overload will temporarily use the liquid life support chamber solution." ”

As the discussion progressed, solutions were found to the problems of outlet sealing of vacuum pipelines, the safety of vacuum pipelines, the elimination of atmospheric motion interference, and the overloading of human bodies.

Next up is another large system that is independent of the mass projection system, the projection spaceship system.

Huang Haojie asked everyone: "Regarding the projection spaceship, everyone has their opinions. ”

For spacecraft, the various research institutes of Galaxy Technology have not made any achievements in this area of research, so they can only look at the space agency.

And Wang Guanghai and others also know that they are the main force of the projection spacecraft, and this is also the basis for the cooperation between the two sides.

After all, the main force of the mass projection system is Galaxy Technology, and if the Dongtang Space Agency wants to increase its right to speak, it must come up with some real materials, and there is no such thing as nothing for nothing.

On the Blue Star, there are currently three countries with manned space capabilities, Mi Lijia, Mao Xiong, and Dongtang.

If it weren't for the International Space Station's refusal to join Dongtang that year, the domestic aerospace industry may not have developed so fast, after all, there is pressure to have motivation.

Thanks to the development of the Shenzhou series and the Tiangong space station, the Dongtang Space Agency has accumulated a lot of valuable experience.

These experiences and data may not be worth mentioning for the hairy bear or the rice grain family.

But for a novice in aerospace like Galaxy Technology, it is definitely very valuable, and with these experiences and data, it is definitely possible to take some detours.

In this way, the two sides can be mutually beneficial, with Galaxy Technology providing the mass projection system and the Space Agency providing the spacecraft system.
