Chapter 652 Deep Diver

After reading the Split Personality Identification System, although this is a first-generation product, it is already ready for use.

This plays a vital role in local security. Some top-secret areas, especially within scientific research bases and intelligence departments, can be put into use first.

Although it is difficult for Thomas's lurkers to penetrate these places, he is not afraid of ten thousand, just in case, it is better to screen them all to feel more at ease.

Huang Xiuyuan finished his inspection work in Langfang, had the stand-in robot sent back to the storage area in Peiping, and then went offline.

the other side.

Lu Xuedong also used a universal stand-in robot to arrive in Australia's Dasha Space City.

Area C15 of Space City.

A row of tall mechas are on display in this factory area.

This model of mecha is codenamed "Deep Diver-1" and is about 2.6 meters tall. It looks a bit like Zaku in the anime "Gundam", with many parts designed in arc shapes.

The reason why it is called a deep diver is actually not because this type of mecha will be used in waters such as the ocean.

Instead, this type of mecha is filled with liquid inside. After constant water pressure, the pilot can live in a simulated blue star gravity in the low gravity environment of outer space.

After more than half a year of testing, 15 of the previous life-support capsule-type gravity simulation capsules have been sent to outer space for testing at the Tiangong Space Station and Guanghan Palace Base.

During the tests in outer space, some minor problems were discovered one after another. On January 20 this year, the pseudo-gravity module completed the finalization of the first generation model.

The pseudo-gravity mecha project that was launched almost simultaneously will complete the finalization of the first generation product this month.

The reason why the pseudo-gravity mecha is so fast is because of the technology sharing of the pseudo-gravity cabin project. The previous test data of the pseudo-gravity cabin in outer space is also useful for the pseudo-gravity mecha.

Shang Qingsong, who was in charge of the pseudo-gravity mecha project, opened the cockpit of a mecha and gave Lu Xuedong a brief introduction:

"There are three modes inside the mecha, namely anti-gravity mode, pseudo-gravity mode, and regular mecha mode."

As soon as Lu Xuedong heard about the anti-load mode, he reacted: "Anti-load mode? Has the respiratory fluid been successfully developed?"

"Yes, Mr. Lu." Shang Qingsong nodded, then opened his tablet and handed it to Lu Xuedong.

Although Lu Xuedong is in charge of the entire Suiren Department's scientific research department, human energy is limited, and he cannot cover everything.

Even Huang Xiuyuan, who has a photographic memory, cannot do this. At most, his memory is stronger than that of ordinary people.

He flipped through the internal report on the tablet.

Breathing fluid is the focus of anti-gravity technology and a big problem. It is even more difficult than hydraulic pseudo-gravity technology.

The difficulty lies mainly in the safety of the respiratory fluid. To use respiratory fluid to replace air and be used in the respiratory tract and upper gastrointestinal tract, safety issues are crucial.

In order to complete this technology, Shang Qingsong and others also cooperated with several biochemical laboratories to conduct human body modification experiments.

Using nanoendoskeleton and other nanomaterials, the esophageal control valve system and respiratory control valve system were created.

After entering the anti-gravity mode, the astronauts will first be immersed in the liquid, then use pipes to connect the esophageal valve and breathing valve, and directly inject the esophageal protection liquid and breathing liquid.

The esophageal protective solution is injected into the esophagus and stomach, and then the esophageal control valve closes, cutting off the esophagus where gastric liquid and gastric acid flow back into the mouth.

The purpose of this is to protect the astronauts' respiratory fluid from being contaminated by gastric acid and stomach food.

If the esophagus is not closed, there may not be any big problems when accelerating, but problems will arise when entering a weightless flight at a constant speed.

Due to the extraction of respiratory fluid, it takes about 15 to 25 minutes to exit the anti-loading mode.

Moreover, after entering outer space, it is impossible to exit the anti-gravity mode immediately. During this period, a buffer time is needed to confirm the safety of the spacecraft.

In other words, astronauts need to maintain weightlessness for at least 30 to 60 minutes or even longer in anti-gravity mode.

In a state of weightlessness, if there is a liquid environment between the respiratory tract and the upper digestive tract, the consequence is that gastric acid and digestive juices will flow upstream and spread to the entire mouth and respiratory tract.

If stomach acid enters the respiratory tract, the consequences will be absolutely disastrous.

Therefore, preparations must be made in advance to isolate the digestive tract and respiratory tract to ensure that gastric acid does not enter the respiratory tract. Even the esophagus cannot allow gastric acid to enter, and gastric acid must be locked in the stomach.

Moreover, the protective liquid that enters the stomach and esophagus must be specially customized to ensure that it is compatible with the human body.

The difficulty of protective fluid is actually easier than that of breathing fluid.

For the respiratory fluid, instead of breathing through the mouth, four openings are opened directly in the chest to connect the two lung lobes, and then two are injected with respiratory fluid, and the other two are sucked out waste fluid to achieve artificial respiration.

The system, called "artificial gills," was developed specifically for breathing in liquid environments.

As for safe respiratory fluid, this project has been developed for almost two years. It was not until four months ago that the emergence of an O8-N4-H2O material made this project progress by leaps and bounds.

This is an oxygen-rich liquid. After entering the alveoli, it can react with the alveoli to generate 4 O2 and 1 N4-H2O. The oxygen is used by the alveoli for respiration, while the supernitrogen water and carbon dioxide are excreted as waste liquid and gas.

When respiratory fluid and protective fluid fill the interior of the human body, and the body surface is also wrapped in liquid, humans can resist acceleration exceeding 80 to 120G by utilizing the incompressibility of liquid.

Although the acceleration of launch vehicles at this stage has not exceeded 10G, the acceleration of Greater China's launch vehicles using N20 high-energy fuel has always been in a relatively high range. During the atmospheric ascent stage, the load caused by the average acceleration is between 4 and 4 Between 8G, the average is 6.34G.

This will cause serious physical burdens for astronauts who need to frequently enter outer space.

After the body modification, through the anti-load mode, astronauts will basically not feel too serious load. Even healthy ordinary people without long-term training can safely enter outer space.

This plays a very important role in exploring outer space.

After all, there are currently 1,369 professional astronauts in the China Space Administration; there are about 5,000 to 6,000 reserve astronauts.

There are currently only 372 non-professional astronauts, that is, scientific researchers.

After all, even if scientific researchers want to go into outer space, the acceleration of the launch vehicle is equal to all living beings.

Therefore, the scientific researchers who can go to outer space are all young and strong, and they are also the most valuable talents of the space agency.

Without solving the acceleration load problem, it will be difficult for humans to enter outer space on a large scale. Like artificial gravity technology, this is also one of the thresholds.

Lu Xuedong looked at the various systems of the Deep Diver mecha and nodded with satisfaction: "Very good. How many units have been manufactured so far?"

"The first batch of 50 units will be manufactured. These deep divers will be transported to the Tiangong Space Station and the lunar base within a month. After a comprehensive test, if there are no major problems, they will enter mass production." Shang Qingsong explained with a smile. road.

"Okay, you continue to improve." Lu Xuedong also made some small suggestions, such as anti-drowning, backup power supply, backup system, etc.

Although the first-generation deep divers were relatively bulky, they were one of the basic guarantees for Greater China’s rapid expansion into outer space.
