Chapter 830 Bricks and Zero-Gravity Simulation

In order to further support private aerospace, after Zhou Rui's press conference, the space agency transferred a team of up to 50 experts to assist in the completion of "Jingtian No. 1".

This is a win-win situation. Taiyi Tiangong has gained a large number of skilled technicians, and the progress and reliability have increased again, while the expert team of the space agency can also accumulate project experience of "recyclable rockets".

Even many technical indicators of "Jingtian No. 1" are similar to the "Long March 5" which has not yet been installed, and can be practiced in advance.

This powerful team of 50 people directly caused the personnel of the No. 2 plant to overflow. Zhou Rui decisively transferred some back and invested in the No. 1 plant where the "mortise and tenon platform" is located.

Compared with "Jingtian No. 1", "mortise and tenon" is a brand-new technology, especially the "Nantianmen" plan requires it to carry more functions, and the workload has increased a lot.

Zhou Rui himself also focuses on this.

On October 10, the Wanhu base was in full swing.

In the No. 1 plant, each area was carried out in an orderly manner.

"The seventh liquid flotation test"

"Simulation begins"

In an ultra-thick glass cylinder, several simulation devices are suspended.

The shrunken "mortise and tenon" simulation part with a plastic shell has a hole on the front in the water, and four robotic arms extend out to capture a flat material.

If this scene is filmed in a movie, it is estimated that it is like some evil alien technology

On the other side, there are "suspension method" tests composed of intelligent devices and more invisible software simulations.

As the world's first equipment with orbital operation capabilities in the true sense, many test items need to be added because the working goal has become more complicated from "simple satellite capture".

It is difficult to obtain a perfect zero-gravity environment on the surface of the earth. Whether it is liquid flotation, air flotation, drop tower, or suspension, it can only be said to be a partial simulation, with advantages and disadvantages.

According to the actual situation, Zhou Rui selected several more suitable types.

Those that require a larger space are directly carried out in the factory, and some others are carried out in the "Load Research Center".

"The eighth suspension test"

"Simulation begins"

Compared to the simulated parts of the "liquid flotation method" next door, this side directly puts on a real thing, with more than three tons of mortise and tenon original parts, dozens of steel cables hanging, including the extended mechanical arm, like a puppet.

The tension applied by these steel cables is dynamically adjusted, trying to offset gravity as much as possible without interfering with the power of the equipment itself, of course, it is only an ideal state.

On the opposite side is a 2*2 thin plate, with connectors at the four corners, and small cylinders on it.

This is the second most important thing of the "Nantianmen Orbital Mechanical Platform".

It can be understood as the floor tiles of Nantianmen, referred to as "tiles"

Zhou Rui vaguely remembers that in his previous life and when he was reborn and couldn't fight, he liked to pick up the tiles on the ground. He picked one without making a sound, and held it in his hand to control it.

I never thought that one day I would send a brick into space.

The surface is the same as the mortise and tenon joints. The "brick" is covered with perovskite solar panels, so it is black all over, with only a little light metal and other functional structures in the inner layer.

At the same time, although the "mortise and tenon joint" has the ability to capture itself, the chemical fuel stored inside is very valuable. For energy efficiency considerations, the four corners of the "brick", which are cylinders not much larger than a thermos cup, are four small-thrust Hall thrusters.

Each only provides 0.8 Newton thrust.

The so-called "Hall thruster", although widely used in various science fiction works, is generally called "Hall thruster", which sounds very high-end, but in fact it has been a technology that has been around for many years.

It was made in 1953, and in 1972, the Soviet Union's meteorological satellite was already equipped with a practical Hall thruster.

The structure and principle of this thing are actually very simple. Ordinary high school students can reproduce the corresponding physical phenomena at home. Generally, the "working fluid" (many types) is ionized by an electric field, and the ionized ions are ejected at high speed under the Hall effect.

Some high school physics experiments include Hall effect experiments. Blowing a candle or stirring the smoke to visualize the thrust can be done.

However, some things are difficult to miniaturize, while others are difficult to enlarge. The most advanced Hall thruster is only "1 Newton force" and is a laboratory product.

Wanting to use the Hall thruster as a "thruster" to leave the atmosphere may be farther away than controlled nuclear fusion, and it is by no means a reasonable technical route.

But if it is just to adjust the posture in the zero-gravity state of the orbit, the Hall thruster is very suitable.

High specific impulse, durable, miniaturized, and electrically driven.

On the "brick", Zhou Rui used four "08 Newton" small thrusters, which are not much larger than a thermos cup.

This little power is difficult to give a chestnut on Earth, but in the zero-gravity orbit, it is enough to adjust the posture and even move short distances, making the "Nantianmen" more flexible and more editable.

The test data was fed back to the computer truthfully, and Zhou Rui quickly screened the key information in the huge and complex content.

His abilities of “unraveling the mystery” and “simplifying the complexity” make him adept at this kind of work.

If ordinary engineers were asked to sort and analyze the data, it might take several days or even longer, but Zhou Rui only needed to glance at it.

Therefore, all the test data would be collected by him, and every day the screen would flash like a slide show.

Now everyone in the base is saying that in addition to the "metaphysical knock", Mr. Zhou has also mastered "quantum reading".

In less than a minute, Zhou Rui made a judgment and said to Wang Tao beside him: "The weightless simulation is still not perfect, and the data fluctuates greatly."

Air, temperature, and material properties will affect various simulations. Taking the "suspension method" as an example, it can only be simulated relatively perfectly on the horizontal plane. Once tangential force or steering force appears, there will be deviations.

Wang Tao: "You can't do magnetic levitation."

"You are talking nonsense. Strong magnetic fields can directly destroy the Hall thruster, and it is so troublesome. Judging from the situation of the last "Capture 0", there is no big problem."

Reliability should be up to standard, as for foolproof? There is no such thing in science.

Just as he was about to continue the discussion, Zhou Rui felt his collar being gently pulled.

Turning his head, it was the "little shower" on his shoulder that gently pulled him.

Little shower: "Highest authority, seed, today"

Zhou Rui was stunned for a while before reacting.

A few days ago, the broken land was conditioned for the last time. Zhou Rui said that it could be sown after three more days of drying.

He was not active in work, but he was thinking about the seeds.

Unfortunately, Zhou Rui made a phone call and said to Xiao Huasha a few minutes later: "The logistics is delayed. The seeds will not arrive until tomorrow."

Xiao Huasha "drooped" and stopped moving.

Wang Tao was no longer surprised by the interactive internal networking device on his boss's shoulder. It was not uncommon in Kaiming Intelligence, but he didn't know that it was a real "intelligent mechanical life".

Zhou Rui looked bored and suddenly said: "Try to control the 'mortise and tenon' and 'brick'. You should have seen the test content many times, right?"

Xiao Huasha said softly: "Okay~"

The highest authority command, there is no possibility of rejection.

The next moment, the mortise and tenon hanging in front of him seemed to be suddenly possessed. The mechanical arm began to reach out and captured the 'brick' in a more flexible way than before, and connected it to itself. The Hall thruster of the 'brick' also cooperated synchronously.

The whole process only took a few seconds.

Zhou Rui and Wang Tao watched together, Wang Tao touched his chin: "I feel something is different but I can't tell."

Zhou Rui directly retrieved a lot of sensor data.

After a moment, he smiled and said:

"The difference is that it is smoother?"

The hardware coordination ability of mechanical intelligence is extremely strong, and it can complete any complex work, but it comes down to "program logic".

That is: receiving-feedback.

But Xiaohuashao is an "intelligent mechanical life". In the familiar content, it can be dynamically adjusted like humans, with coherence, predictability, and smoother perception of the situation.

Although I didn't expect Xiaohuashao to play a practical role so early.

But it would be good if I could add an extra layer of insurance.

Zhou Rui said to Xiaohuashao: "Well done, I will reward you with more advanced fertilizer later!"

Xiaohuashao was obviously "excited" and the robotic arm was lifted up!
