Chapter 750: Chang San Yi Completed

“The lifting hand is not level enough and is slightly higher than seven millimeters at seven o’clock. Re-balance the pulling force.

"receive!"

"Team A is ready. How is the pre-connection of the fuel pipeline going? It will take 10 minutes!"

"The pre-connection is completed and we are moving to the work platform on the seventh floor."

One instruction after another came from Shan Chunyuan's mouth. In the launch tower, dozens of people from the engineering team were working in an orderly manner.

Although he successfully got along with the engineering team, he also gained enough face.

But such an important project cannot have two brains after all.

So Zhou Rui took the initiative to play the role of an ordinary engineer and had no intention of competing with Shan Chunyuan for command.

Anyway, he didn't come here to learn commanding. He would rather practice it than play the role of Shan Chunyuan.

But when it comes to the next rocket of its own, this will no longer be the case.

It was the second day after entering the tower, and the "Chang Sanyi" had already taken its preliminary shape, and it was beginning to install the "Second Stage Arrow", which is the third building block of the rocket.

Director Sun, wearing a safety helmet, came to inspect the progress. When he saw Shan Chunyuan, he leaned over.

"How's the work going?"

Shan Chunyuan said solemnly: "The progress is about 63%. The load bay can be installed in the evening, and the inspection can be completed tomorrow."

The final assembly of the rocket requires a quick word, otherwise such a big thing is made of lightweight metal, and its own weight will be enough to cause errors and damage after being stored for a long time.

Director Sun raised his eyebrows: "It's faster than expected. I thought it would take four days? Can it be completed in three days?"

Shan Chunyuan looked at a figure on the seventh floor unconsciously.

The tone was complicated, but he still said it truthfully: "Because Mr. Zhou is extremely efficient, he is responsible for a certain amount of group scheduling work, and he is extremely familiar with riveting and is better than all of us."

Director Sun was a little surprised, but he immediately recalled Mr. Zhou's previous dazzling "project experience" and understood.

I see

Chief Engineer Kunpeng is here to drive screws!

But their space agency is so awesome!

Well, he didn't dare to really think so. If people in the aviation field knew about it, he didn't know how many times he would be scolded.

Speaking of which, Director Sun had previously agreed to Zhou Rui's "idle is idle" plan, but deep down, he didn't dare to believe too much that this person could really "smoothly" solve the rocket recovery technology.

But for some reason, seeing that calm, calm and down-to-earth figure made me feel more confident.

This is not Zhao Kuo.

This is Zhuge Wuhou.

Shan Chunyuan pursed his lips and said, "I thought that Master Zhou would be gesticulating like he was preparing for the field."

Director Sun smiled and said, "Is that really just gesticulating? With your temper, if Mr. Zhou really acted recklessly, wouldn't you have turned your back and sued me long ago?"

Shan Chunyuan touched his nose awkwardly.

Director Sun: "You didn't come to me to complain, so I knew you had probably been subdued by him."

Shan Chunyuan immediately quit: "What do you mean by subduing yourself? I'm a grown man and I'm just talking about pets!"

The most I can say is that I feel sympathy for each other! It’s a recognition among engineers!

Director Sun suddenly said: "The launch of Chang'e 3 has been completed. Thank you for your hard work. Please continue to work hard. The rocket recovery project will still require the help of the engineering team, but at that time, Mr. Zhou will be in charge."

Shan Chunyuan waved his hand irritably: "I understand, I will continue to direct."

——————

Upstairs, Zhou Rui, wearing a safety helmet, was riveting two huge components.

He is extremely skilled at this job, and he is already doing what he does!

Speaking of which, in fact, the accuracy requirements for rocket riveting are lower than those for fighter jets.

This is because the two have different requirements for system stability.

For fighter jet riveting, the stability requirements are designed based on thousands or even thousands of hours.

As for a rocket, it only takes 200-300 seconds from launch to completion.

If there is no problem for 200-300 seconds, it will be alive!

The only difference is that many rocket rivets use "explosion bolts" containing explosives to achieve multi-stage separation, which requires more care.

The TV's effect of flying and breaking away is achieved by this design.

Che Gan followed his boss and was doing the same job, while he was discussing the Rockets with his boss:

"Exploding bolts will greatly reduce the service life of components. Even if we can recycle them every time, they will not be used two or three times. This must be changed!"

Zhou Rui was doing two things at once, his eyes were focused, and he said:

"The main thing is rocket separation, which requires instantaneous response. There are dozens of riveting points in a circle. The time difference between the front and back separation cannot exceed 0.2 seconds, otherwise it will affect the rocket's flight attitude. With conventional technology, this is the most stable method."

Zhou Rui also smiled as he said this: "But we have an unconventional method. The riveting parts can be changed into smart device buckles. It's very simple."

Che Gan said with emotion: "Sometimes I have the illusion that our 'mechanical intelligence' seems to be born for aerospace. Looking around, it feels like it can be innovated everywhere."

"I even think that in the future, rockets may be able to launch themselves, just like the unmanned bus outside the smart town, just for delivery."

Zhou Rui was amused by this metaphor. It may work technically, but it may not work legally.

But during this time, he and Che Gan had similar feelings.

Even deeper than Che Gan thought.

"Mechanical intelligence", the black technology he got from the revelation of heaven, seems to be really very suitable for aerospace.

To be more precise, it is very suitable for space exploration.

Whether it is the construction of aircraft, or unmanned occupation such as the "Moon Colonization Plan",

or in the more distant future, interstellar resource acquisition and longer interstellar voyage.

It is so suitable that he even thinks that this technology is used for this purpose.

What is this?

A few more years of detours?

Due to the speed requirements of "vertical assembly", all work is carried out very quickly.

At noon, the second-stage sub-arrow was installed.

By eight or nine in the evening, the "payload cabin" had already begun to be installed.

The entire "Long March 3B" has reached 45 meters, and including the "transfer platform", it has reached the height of 17 floors.

This behemoth has become more and more complete.

At eight o'clock in the evening, the special vehicle slowly drove in, bringing the penultimate "building block" of the Long March 3B.

Payload cabin.

When Zhou Rui was not involved, the Chang'e-3 project team had already been at the "preparation site" to put the "Chang'e nesting doll" into the payload cabin and fully fixed it.

Here, only hoisting was carried out.

Sun Ze, Zhang Xianpeng, and Hong Anran also came to the launch tower.

Hong Anran looked up and tried to find Zhou Rui, but she could not see anything.

She had not seen Mr. Zhou for several days. He came to Xichang as a member of the "Yutu Group".

But he had been hanging out in the "rocket engineering group". Many people in the "Yutu Group" had forgotten that they had an "external expert".

At 11 o'clock in the evening, the payload cabin was installed.

Since the engineering group had worked for more than fifteen hours that day, all members were forced to rest.

At eight o'clock the next morning, the last "building block" of the "Long March 3B": the fairing arrived.

Fairing: The "tip" of a missile or rocket, used to change the aerodynamic shape and protect the "payload" from the influence of aerodynamic thermal effects and acoustic vibrations. It is the only "left and right structure" part of the rocket components.

It split in the middle when it separated.

At 10 a.m., the fairing was installed.

The rocket carrying the "Lunar Exploration Project Phase II - Chang'e 3 Project" has completed vertical assembly and entered the inspection and acceptance stage.

The planned launch date is two days later.

The Space Administration has invited a large number of official media, including Yangma.

The Science and Technology Channel will broadcast live non-stop from three hours before the launch.

This is an important project that will be on the "News Broadcast" regardless of success or failure.

Although it has been tested hundreds of times during the assembly process, all members of the rocket engineering team still have to continue to test thousands of times in two days.

Use thousands of boring and repetitive times.

To pursue a "perfect"!

And when everyone entered the inspection stage.

Zhou Rui, however, stood alone on the 20th floor of the "launch tower".

The huge creation in front of him, looking down from above, also has a unique flavor.

The whole body is pure white, but there is a red flag printed on the fairing.

After a moment of hesitation, he stretched out his palm and touched the outer shell of the fairing.

Finally, the installation is completed.

It forms a whole.

Then

Let's try to use "similar methods" to transform it.
