With Huang Yuting and Xu Yun coming up with two plans.
The temporary version of the gravity gradiometer does not have any difficult problems in terms of structural principles.
However, considering that it was already approaching six o'clock in the morning, Huang Yuting and Lin Chen, who were tired from traveling and traveling, could still persevere mentally, but they were already showing signs of obvious fatigue in terms of physical strength and energy.
Therefore, at Xu Yun’s insistence.
Everyone, including Ge Tongyou and Xu Yun himself, returned to the guest house to rest temporarily.
Tell the truth.
Compared to the Ritz-Carlton in Chengdu, the guest house at the Xichang Satellite Launch Base is relatively average.
After all, that's the nature of the base.
Since it is an official scientific research institution, the overall style of the guest house must not be too luxurious and flamboyant, and there must be no crystal ceiling, gold-plated handrails or anything like that.
However, although the decoration of the guest house is relatively simple, the indoor facilities are still very good, and the mattresses and quilts are very clean and comfortable.
Not long after Xu Yun went to bed, he fell into a deep sleep.
Before falling into a dream.
Suddenly a thought flashed through his mind:
It seems that the two meals I owe Cockroach Lady will be postponed again...
A night of silence.
........
in the next two days.
Xu Yun, Ge Tongyou, Huang Yuting and others have made many optimizations on the structure and several major modules.
Academician Pan accompanied Mr. Wang back to Chengdu first. Although Mr. Wang was occasionally energetic, most of the time he was still depressed and all indicators were not very healthy.
For example, Mr. Wang's blood oxygen concentration has been floating between 91 and 93. This value is really unhealthy.
Therefore, even though Xichang has good recuperation conditions, Academician Pan accompanied Mr. Wang back to Chengdu.
Two days later.
Seven o'clock in the morning.
Ge Tongyou, Li Hua, Xu Yun and others waited at the gate of the base early.
Both Xu Yun and Huang Yuting looked excited and expectant at this time.
After a while.
Lin Chen, who had been paying attention to the distance, pointed forward and said loudly:
"Sister Huang, the car is here!"
Upon hearing this, Huang Yuting suddenly raised her head and looked in the direction Lin Chen pointed.
I only see this moment.
On the avenue outside the launch base, a convoy of six trucks slowly appeared.
The exterior of each vehicle is painted with green camouflage coating, and the cargo box is covered with camouflage netting to prevent satellite photography. It is obvious that it has an unusual origin.
Upon seeing this, everyone stood up one after another and waited at the entrance.
A few minutes later.
The convoy stopped about five meters from the entrance.
The car door opened quickly and a man in his thirties jumped out.
The man was wearing casual clothes at this time, but his whole body exuded a military aura, and his face was extremely resolute and steady. At first glance, he was a reliable and upright man.
After getting off the car.
The man held a very thin document, walked quickly to everyone, and asked:
"Hello everyone, who is Chief Engineer Li Hua?"
Hearing this, Li Hua took a step forward and handed over the work permit he had prepared:
"Hello, comrade, I am Li Hua."
The man took the work permit and looked at it carefully for a while, then handed it back to Li Hua:
"Hello, Chief Engineer Li, I am Cao Yi, the person in charge of the confidential transport fleet of the xx department under the 29th Institute, and I serve as a major."
"I was ordered to come here today to hand over the relevant equipment to you. What I have in hand is the handover list."
“Gong Li, where do you think it would be more appropriate for us to unload and hand over the goods?”
Li Hua shook hands with Cao Yi, and then pointed toward the inside of the base:
"We have prepared the location. It's right inside the base. Major Cao, let the driver drive the car in."
Cao Yi nodded when he heard this, turned around and made a gesture to the convoy driver:
"Wei Fan, drive the car in!"
Wait until the car starts moving.
Xu Yun on the side looked at the fleet with some curiosity.
The 29 institutes Cao Yi mentioned refers to the 29th Institute of China Electronics Technology Group Corporation.
It is a very special scientific research unit like Mianyang Institute of Chinese Physics...that is, Mianyang Ninth Institute.
Although Xu Yun worked at Chengdu Aircraft Manufacturing Co., Ltd. for many years in his previous life, his understanding of this organization was quite limited.
I only vaguely heard that there are Gundams, Star Destroyer Cannons, and Artificial Tiga in 29.
Today's meeting was Xu Yun's first formal contact with people from Institute 29 in his two lifetimes.
Then under the guidance of Li Hua.
The convoy drove into the base one after another and stopped at the entrance of a warehouse.
At this time, several forklifts and equipment to assist in unloading were on standby at the entrance of the warehouse. After the truck tailgate was lowered, the workers quickly unloaded the boxes sealed with metal or wood.
About half an hour passed.
All the unloaded boxes were placed in the warehouse, divided into two areas on the left and right according to the wood and metal shells.
Wait until the goods are unloaded.
Cao Yi first took Li Hua to the wood area, pointed to this area and introduced:
"Gong Li, according to the classification in advance, the wooden boxes contain some relatively basic and sturdy equipment."
"For example, landing gear, gyroscopes, three-prong slides, wind deflectors, etc."
"So I would like to make a suggestion, let's start the inventory and inspection from here, and get the simple links done first."
Li Hua nodded:
"no problem."
There are a total of thirteen or four wooden boxes, which are neatly stacked on the left side of everyone.
The smaller one is about the size of an urn, the larger one is about the same as a coffin, and the largest one is almost as tall as an incinerator.
With the assistance of Cao Yi's fellow technicians.
These wooden boxes were quickly opened intact.
Li Hua and Ge Tongyou took their assistants and divided them into two parts and inspected them one by one.
The modules loaded in the wooden boxes are very simple and belong to the basic structure that the Xichang Satellite Launch Center itself can build.
The reason why the 29th Institute was asked to assist in the forging of these modules was because the processing plant within the base was in a state of combat readiness all year round, and some procedures and procedures were required to start up.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! It takes a long time to come and go, which is much more than asking 29 to help polish it.
This part is also the easiest part of the inventory. Just check if there are any serious dents on the outside.
So it takes less than ten minutes.
Li Hua and Ge Tongyou finished counting and returned to Cao Yi:
"Major Cao, there is nothing wrong with these devices."
Cao Yi still looked calm, and turned to look at the other metal box:
"In that case...Gong Li, let's start counting the key equipment. I won't get involved in this part, Gong Li. I'll leave the details to you."
Li Hua nodded to him again and led Ge Tongyou to a metal box at the front.
Ge Tongyou first bent down, found a number on the box and reported it:
"A12."
Li Hua took out a tablet-like device from his body, fiddled with it a few times, and a series of numbers quickly appeared on the screen:
"."
This is the electronic code sent by No. 29 in advance. After all, the gravity gradiometer is of great importance - even the beggar version is the same.
In order to avoid arguing and avoid suspicion, this method is necessary.
Ge Tongyou quickly entered the numbers.
After a while.
The metal box made a low clicking sound, and a small opening of about one centimeter slowly opened at the top.
Li Hua put his finger in his mouth and lifted it up with force.
The scene inside the metal box suddenly appeared in front of everyone's eyes.
This box numbered A12 contains a precision device similar to the head of a sewing machine. It is silver-white in color and has a digital display screen directly above it.
This is a remote sensing balance instrument, which is one of the lifeblood components of the gravity gradient instrument.
The accuracy of the remote sensing balancer will be directly related to the effect of the balance module, which is somewhat similar to the chicken head stabilizer in the photography industry.
Then Li Hua carefully took it out and placed it on a mobile pallet next to him.
There is a tool similar to a microscope installed on the moving platform, but it does not have components such as eyepieces or objective lenses, and its size is much larger than an ordinary microscope.
This thing has a name that sounds weird to non-industry people, it's called a three-dimensional coordinate measuring instrument.
This is a high-precision equipment for detecting geometric tolerances of workpieces. It has a high technical content and is extremely expensive to build.
For example, the three-coordinate measuring instrument next to Li Hua cost more than 1.7 million yuan.
Don't think this price is exaggerated. The prices of some non-military CMM brands are not much lower than this.
For example, the price of better three-dimensional coordinate measuring machines from brands such as Hexagon or Faru is close to one million.
In many car factories, you can often see workers with a monthly salary of less than 20,000 yuan carrying out inspections using three-dimensional coordinate measuring machines that sell for millions. The basic price of this thing is ridiculously expensive...
Two minutes later.
A three-dimensional CAD digital model and wireframe model appear on the screen of the three-dimensional coordinate measuring instrument, as well as an IGES file bar showing relevant results.
"Bearing span error 0..."
"Anti-angle swing capability 4/1000...."
"Z-axis accuracy 0,0,100,0,1,0..."
"Small gaps 122.500, 182.550, 8.040..."
Li Hua carefully read the values line by line.
Then he raised his head and looked at Ge Tongyou. Seeing that Ge Tongyou did not raise any objection, he said to Cao Yi:
"Major Cao, the accuracy of the A12 is intact, there is no sign of wear, and it fully meets our requirements."
Cao Yi's eyes moved slightly when he heard this, but he still didn't show too much joy, but still said calmly:
"Okay, Mr. Li, let's proceed with the docking of the next box."
Li Hua nodded and led Ge Tongyou to another box.
"A05."
"."
Click——
The box opened quickly.
The equipment loaded in the box this time is three metal robotic arms, each with two obvious connection grooves.
Each robotic arm is folded in half. The folded length is about 50 centimeters and the width is only a few centimeters.
Li Hua's assistant quickly took out the robotic arms one by one, spread them out, and placed them on the pallet as well.
However, this time the person in charge of inspecting the equipment was not Li Hua, but Huang Yuting - these three arms are the measuring arms of the gravity gradiometer, and the groove is where the measurement module is placed.
"Length 95.28...."
"Width 6.666...."
"The pressure at the joint is 28.7psi..."
"The diameter of the graduation circle is 0.833..."
A few more minutes passed.
Huang Yuting looked away from the three-dimensional coordinate measuring instrument, turned to Li Hua and nodded:
"Gong Li, the parts meet the requirements."
Li Hua suddenly breathed a sigh of relief.
After the measurement module has been completed by Xu Yun...or the HKUST Listening Project Team.
There are only three most important links in the gravity gradiometer:
Remote sensing balancer, measuring manipulator and power module.
Among them, the power module is solved by the Xichang base itself. After all, as one of the domestic rocket launch hubs, the Xichang base cannot lack power equipment for anything.
Therefore, what they really need to inspect are naturally the two remaining components, the remote sensing balancer and the measuring arm.
Of course.
When you see this, some students may ask, what about the 50x50 lattice?
This involves the issue of process stability.
True.
Although the 50x50 lattice is very important in the entire gravity gradiometer, the manufacturing process is also quite complicated, and it is difficult to produce it with a general mechanism.
But for institutions like 29, high-density lattice is an already mature technology.
It does not require detailed data provided by the Xichang base to go through the customization process like the remote sensing balancer and measuring manipulator. It only needs to calculate the arrangement of the crystal lattice.
That is to say, there are not many institutions that master the corresponding preparation process, but as long as you find the right institution, production is very easy.
This chapter is not over, please click on the next page to continue reading! In a way, it is similar to nuclear weapons:
Not counting several nuclear-hiding countries, there are only five gangsters in more than 200 countries in the world who possess nuclear weapons, and their technology is absolutely high-end.
But for the five gangsters, it is not difficult to produce nuclear weapons. They can produce a neon happy bomb with just a few clicks of their fingers.
The 50x50 lattice plate is almost the same.
Li Hua then took Ge Tongyou to unpack and inspect several other boxes.
sensor.....
Falling prism.....
Ion pump......
Servo coil......
Surrounding sensitive twisting wire....
One by one, parts passed the inspection and handover.
More than an hour later.
Li Hua wiped the sweat from his forehead and took the initiative to reach out to Cao Yi:
"Major Cao, all items have been handed over without any problems."
Hear this.
Cao Yi, who had always kept a straight face, finally breathed a sigh of relief, with a look of relief on his face, and stretched out his hand to shake Li Hua's hand.
After letting go of your hand.
Li Hua thought for a while and asked Cao Yi:
"Major Cao, are you on a tight schedule for your escort mission today?"
Cao Yi was stunned when he heard this. Although he was confused, he still said honestly:
"It's not very urgent. Since these goods are of great importance, the time given by the superiors is sufficient."
"No matter how long we stay here at the base, we just need to report to the XX troop station in the suburbs of Xichang at six o'clock tonight."
"It's not convenient for me to disclose to you the location of the troops' station, but it's only an hour or two away from here."
Li Hua nodded slightly when he heard this, and suddenly made an invitation::
"In that case, Major Cao, are you interested in observing the assembly process of the gravity gradiometer?"
"To tell you the truth, although our structural parts are a bit simple, our precision is at the top of the world."
"It is not an exaggeration to say that today is likely to be a milestone day for domestic measurement... no, it should be said that the national defense industry will be recorded."
Cao Yi was stunned again and looked around in astonishment:
"Gong Li, you mean...to assemble it here?"
Li Hua glanced at Ge Tongyou beside him, and they both nodded:
