The rise of nanometers

After leaving the 3067 Research Institute, Huang Xiuyuan went to the 3058 Research Institute located in the Great Sandy Desert of Western Australia.

This research institute is located southwest of Dasha Aerospace City, about 85 kilometers away.

The 3058 Research Institute is next to a road, opposite a new agricultural town where cotton and sugar cane are grown.

Winter in the northern hemisphere, and summer in the southern hemisphere.

The sun is shining brightly, and neat cotton fields are filled with densely planted cotton. The growth cycle of cotton is about 180 days. It is in the growth period at this time, and the cotton fields are green.

Huang Xiuyuan got off the car at the entrance of the institute. Song Yijian, the director of the institute, and Hong Wenxin, the chief researcher, were already waiting at the door.

"Mr. Huang, welcome to come and give us guidance." Song Yijian took the lead to step forward.

"Mr. Huang, welcome!" Hong Wenxin nodded slightly. He was obviously gentle and not overly enthusiastic.

The 3058 Research Institute is not an industry of the Suiren Department, but an industry of the Academy of Engineering. However, their cooperation with the Suiren Department is very in-depth.

Huang Xiuyuan didn't pay too much attention to it. After all, there are many scientific researchers with eccentric personalities. The more talented they are, the less they like the world. They like to immerse themselves in their own world.

"Let's go inside and talk."

Song Yijian immediately led the way into the working area of ​​the research institute. After changing protective clothing, he came to an assembly room covering an area of ​​more than 2,000 square meters.

In the assembly room, workers are busy assembling a piece of equipment.

From the appearance, the device looks like a large refrigerator lying flat on the ground, with a length of 2.8 meters, a width of 1.2 meters, and a height of 1.2 meters.

Above is an openable hatch with a transparent window for observation. The window can see the situation inside the cabin, but the window can be closed and opened by adjusting it.

After opening the hatch, the space inside the hydraulic cabin is designed in the shape of an arc capsule, with a length of 2.4 meters, a width of 0.8 meters, and a height of 0.8 meters.

There is a pillow-like object, and the bottom of the cabin is an adjustable ergonomic bed that allows the user to semi-lie.

In addition, there is a waterproof computer system in the cabin to ensure that users can operate the hydraulic chamber in the cabin and even temporarily take over the command of the spacecraft.

This in-cabin computer, combined with the nano-display on the breathing helmet, allows users to use the in-cabin computer without any barriers.

Huang Xiuyuan asked: "Dr. Hong, how are the human experiments going now?"

"The experiments on the ground were very successful. We have conducted many tests on the five currently modified hydraulic tanks. Among them, 10 volunteers have tested in the hydraulic tanks for a total of 385 hours." Hong Wenxin raised his glasses and explained. road.

Huang Xiuyuan took Song Yijian's experimental report and glanced through it for a while.

Judging from the test report.

Currently, there are 5 hydraulic cabins and 50 volunteers conducting human experiments on hydraulic chambers, and a total of 1,583 experimental tests have been conducted.

The main purpose is to test different hydraulic pressures, different test times, and differences between individuals.

Although many animal experiments have been done before, humans and animals are not the same species after all, and various differences must be carefully verified.

At present, Hong Wenxin's team has initially determined the optimal range of hydraulic pressure that the human body can withstand. Within this range, the pressure endured by the human body is almost equivalent to the gravity of the Blue Star ground.

Although there are certain differences between hydraulic pressure and gravity, this is currently the best solution to achieve pseudo-gravity under the current technical level of mankind.

Without the development of pseudo-gravity technology, human development in outer space will be limited to one year, and astronauts must be constantly rotated.

Even if a rotation plan is adopted, astronauts cannot enter outer space frequently. A well-trained professional astronaut can perform duty in outer space for no more than 5 years in his life.

Based on the average life span of a human being of 75 years, astronauts work from the age of 25 to the age of 55, which is about 30 years of work.

In these 30 years, the time for astronauts to actually enter outer space is only 5 years at most, or about one-sixth.

Frequent entry into outer space may cause irreversible damage to astronauts' bodies.

If a hydraulic cabin is used to alleviate space syndrome, the working time of astronauts in outer space will be increased to about 10 to 15 years.

If equipped with hydraulic exoskeleton armor, astronauts can even live and work in outer space semi-permanently.

This can greatly alleviate the commuting pressure between the homeland and outer space.

According to the expansion rate of the Guanghan Palace base, the expansion and construction of 30 to 35 living cabins will be completed by the end of the year, and the expansion is planned to 150 to 170 living cabins next year.

At the same time, there are plans to build a Laurel base on the back of the moon next year.

The number of astronauts on duty on the moon is expected to increase to about 200 to 240.

By then, even if the Chang 13 has completed technical verification on the Tianmen Space Station, the transportation capacity required for 400 to 500 astronauts to and from the space station every year is not a small amount.

Even if we use launch vehicles such as Chang 11 and Chang 12, and replenish fuel on the moon, the number of people that can be transported is limited.

Currently, the China Space Administration often uses the Tianzhou-3A and Tianzhou-3B modified from the Chang 11 spacecraft for spacecraft between the Blue Star and the moon.

Tianzhou-3A and Tianzhou-3B weigh about the same, about 256 to 260 tons. They can fly in low-Earth orbit to the lunar orbit and the lunar surface, and the payload is generally about 80 to 92 tons.

Among them, Tianzhou-3A is a cargo transport spacecraft; Tianzhou-3B is a passenger/cargo dual-purpose spacecraft.

When the lunar base cannot replenish fuel, if Tianzhou-3 relies on its own fuel to return to Blue Star's low-Earth orbit, the payload will be compressed again, leaving only about 45 to 53 tons.

The previously launched Tianzhou-3A basically did not consider return and utilized the payload to the extreme; while Tianzhou-3B, due to the consideration of returning to Blue Star's low-Earth orbit, can usually only carry about 30 tons of cargo. Plus a 17 ton cockpit.

This 17-ton cockpit can carry up to 5 astronauts at a time.

Taking into account the pressure on the flow of personnel on the Blue Star Moon in the next few years, the China Space Administration has placed a new order with the China Aerospace Science and Industry Corporation to produce a batch of Tianzhou-3 spacecraft specifically for passenger transportation.

The model is designated as "Tianzhou-3C", which uses a cockpit and two passenger cabins, and can carry up to 24 astronauts at a time.

If the fuel factory at the Guanghan Palace base is successfully put into operation, the passenger transport capacity of Tianzhou-3C can reach a maximum of 55 people one way.

The increasingly large number of people stationed on the moon will eat up a large part of the space load. This is what Huang Xiuyuan has to consider.

The current number of personnel stationed on the moon is 30 to 50, and next year it will be 200 to 240.

What about next?

Without solving the problem of astronauts living in outer space for a long time, Huang Xiuyuan estimates that the number of personnel stationed on the moon and its endurance limit should be around 5,000 to 6,000 people.

Although the moon is not too big, it is still a planet. What can five or six thousand people do? Even if it is equipped with highly automated robot assistance, it will be difficult to continue to expand.

Therefore, the hydraulic cabin in front of us has become one of the most important technologies currently.

Even if the cost is as high as more than 8 million yuan per unit, Huang Xiuyuan plans to put it into mass production.

He discussed with Hong Wenxin and others for more than an hour before leaving the institute in the evening and exiting the stand-in robot mode.
