This place is not far from the Jiuquan satellite launch base. Along the highway, in the vast Gobi Desert, there are huge white factories. They are an industry under Xingchen Technology and the Star Launch Vehicle Assembly and Testing Company.

Rocket parts are produced in many factories located in Xingchen Technology across the country, and then transported to a place not far from the launch site for the final assembly test. If the test passes, the rocket will stand on a platform deep in the desert, choose a clear weather and launch it.

After getting off the plane, Luo Jia was taken directly to the factory by the company's car. When he walked into the warehouse, he saw a row of Star A1 engines. Other warehouses also contained parts such as carbon protective shells, balancers, and communication terminals.

Wang Zhiyu, the head of the Rocket Assembly Plant, introduced to Luo Jia: "These twelve engines are the first batch that have just been shipped from the factory. With the start of full production, the production speed of the factory will become faster and faster. In the end, we will maintain a reserve of no less than 500 A1 engines. After all, although the a1 engine is said to be infinitely recycled, it will also be cleaned after each use. The reserve of engines can maximize the launch efficiency of the launch vehicle."

"We will also optimize the A1 engine according to the maximum launch efficiency of other parts. Although this will cost the company a lot of money, I think it is still worth it. After all, the data given to me by Mr. An is 13,000 tons of goods waiting to be sent to space."

Luo Jia didn't say much. Near-Earth space station, synchronous space station, and the first space elevator, 13,000 tons is definitely not enough. Anran only gives conservative numbers. As the space plan advances rapidly, this number will gradually increase.

It would be great to wait until the first space elevator is built. As the old saying goes, everything is difficult to start with. As long as the first elevator is available, although its power may not be so high and its carrying capacity may not be that large, as long as it can be built, it can abandon rockets and transport them quickly and continuously into space at an astonishingly low price.

As for the Rockets, the Russians and Lighthouse Kingdom can play whatever they want. The Chinese people still like to take the elevator, so they will not accompany them.

"How is the test going?" Luo Jia asked.

"It went very smoothly." Wang Zhiyu said excitedly: "I have tested seven units and passed them all at once. The Nantong Manufacturing Factory's technology is amazing! The test data of each engine is almost no different. I have been working in aerospace for my whole life and have never seen such excellent consistency."

Wang Zhiyu praised the quality of the a1 engine. Luo Jia smiled and said, "The reason is not difficult to understand. First of all, it is because the company's mechanical department has manufactured the world's highest precision five-axis and seven-axis linkage machine tools. The core force of the machine tool industry comes from our ultrasonic motors. The performance of the motors we manufacture is far greater than that of the harmonic reducer motors of the Neon Diren Group."

"The second is that the high-precision robotic arms and 3D printers can improve the overall assembly quality, while the 3D printer is even more powerful, and can handle complex and difficult components that cannot be completed by five-axis machining centers."

Wang Zhiyu was stunned and said in surprise: "Why has our 3D printing technology suddenly become so powerful? I have never heard of it before!"

Luo Jia smiled and said, "I must correct it. Our 3D printing technology is not suddenly powerful. Unless you are illuminated by gamma rays, suddenly become Hulk, or bitten by ancient spiders, and become Spider-Man, no one in this world will suddenly become powerful."

"Wen Chengling is the world's top laser expert. His joining has allowed us to solve the technology required for ultra-ultraviolet laser hybrid lithography machines. The laser technology used in lithography machines continues to be derived, which is the laser engraving required by 3D printers."

"In addition, Zhang Yuechuan's optical team solved the problem of optical measurement, Zheng Lin, Bai Xianyong and his team solved the intelligent industrial software needed for 3D printers, plus the high stability of ultrasonic motors, and the various processing-resistant metals and carbons developed by the materials science team, all the results are added together, so we have the world's strongest 3D printing system."

"At present, the 3D printing department is still expanding rapidly. I believe that in a few years, we can use 3D printing technology to print out the entire launch vehicle. That will be another great beginning of the industrial revolution."

Listening to Luo Jia's passionate words, Wang Zhiyu's heart was filled with storms and it was difficult to calm down for a long time.

As Luo Jia said, everything is difficult at the beginning. Xingchen Technology has passed the most difficult stage of survival, entered the stage of rapid development, and has arrived at the season of harvest.

All previous R&D results are the foundation of the company. The company grows and grows rapidly on the foundation. Every now and then, it will bring some black technology to the whole world.

After the shock, everyone thought carefully that there may not be many truly new technologies. Just recombining the original technologies is enough to scare everyone.

In the past, we always felt that the West was so unattainable and insurmountable.

Now looking at this world again, we find that Westerners are actually very lazy and hypocritical, and they also have the smell of body odor that can kill people, like a group of animals that have not evolved completely. So we call Westerners white-skinned pigs and dislike them in various ways.

From a foreign uncle to a white-skinned pig, the transition between the middle is not because the West has changed, but because we have gradually completed the accumulation of industry and technology. In the end, the gap will gradually disappear, and we will look at the world from the same height as the West.

Only after equality between people can what you see and feel approach reality. This is like a teacher-student relationship, or a subordinate's love for his boss. Modern psychology tells us that there are factors for worship of rights. For example, when you arrive in Africa, black girls will definitely live to the death of what you like. This is also a phenomenon of worship of rights. Human beings are born with inherent attributes.

"The engine test will be conducted in the afternoon. Should Mr. Luo go and take a look in person?" Wang Zhiyu suggested to Luo Jia.

After thinking for a moment, Luo Jia nodded happily and agreed, "Okay."

...

The a1 type engine is placed flat on the machine table, with the injection port facing the outside desert, and the mechanical structure itself is connected to dense pipelines and cables, which are connected to the central computer in the control room.

Data on the screen shows that the total weight of the A1 engine is 10,000,3 tons, everything has been prepared, waiting for the test to unfold.

Yes, the total weight of the A1 engine with a thrust of 550 tons is only a little over one ton. For the same liquid oxygen methane engine, the rd-171 thrust of the Russians reaches 800 tons, and the weight is close to 11 ton, which is more than ten times heavier than the A1 engine.

The slender and slender body is covered with dull gray-black. The reason why the a1 engine can be so lightweight is mainly due to the materials department. Super carbon fiber and graphene are not only light in weight, but also have a strength and heat and corrosion resistance, but also far exceeding the current synthetic metals.

Unless the legendary alloy artifact trititanium alloy is released, the graphene and carbon fiber of Xingchen Technology are destined to be unparalleled.

As for the slender and slender engine structure, it is mainly designed for the joint business of multiple engines.

The so-called multi-machine joint operation, a simple and crude explanation means that it means tied a row of engines together.

In principle, it is not difficult to combine multiple engines. What is difficult is the linkage system. Through complex calculations and precise control, each engine is controlled to turn the vector nozzle in the most correct direction without even a millimeter error. The injection system perfectly controls the release and weakening of thrust. These technologies are the most difficult.

The first test was the vector nozzle and various static parameters, and the command was issued from the control room. The nozzle continued to rotate with the command. Under the drive of the micro ultrasonic motor, the angle was quickly adjusted. At the same time, the computer collected engine data and checked with the original data.

"The static test has been completed. Mr. Luo, please light it."

After Wang Zhiyu said that, he pointed to the largest red button on the console.

Luo Jia paused for a moment, then stretched out his right hand and pressed it down gently. After a brief damping feeling, a snap sound came from his ear, followed by a loud bang outside the control room.
Chapter completed!
