This place is not far from the Jiuquan Satellite Launch Base, along the highway, in the vast Gobi, there are huge white factories, which are the subordinate industries of Xingchen Technology, Xingchen Launch Vehicle Assembly and Testing Company.

The rocket parts are produced in various factories of Xingchen Technology in various factories across the country, and then transported to this place not far from the launch site for final assembly testing, if the test passes, the rocket will be standing on a platform deep in the desert, and launched in clear weather.

After Luo Jia got off the plane, he was directly taken to the factory by the company's car, and when he walked into the warehouse, he saw a whole row of Xingchen A1 engines, and other warehouses also put carbon protective shells, balancers, communication terminals and other parts.

Wang Zhiyu, the person in charge of the rocket assembly plant, introduced to the Luo family: "These twelve engines are the first batch just shipped from the factory, with the beginning of full production, the production speed of the factory will be faster and faster, and in the end, we will maintain no less than 500 A1 engine reserves, after all, although the A1 engine is known as infinite recycling, but after each use, it is necessary to clean up the work, and the reserve of a sufficient number of engines can maximize the launch efficiency of the launch vehicle." ”

"Not only the A1 engine, but also other parts will be optimized according to the maximum launch efficiency, so although it will cost the company a lot of money, but I think it is still worth it, after all, the data given to me by Mr. An, there are 13,000 tons of goods waiting to be sent to space."

Luo Jia didn't say much, the near-earth space station, the synchronous space station, plus the first space elevator, 13,000 tons is definitely not enough, Enron is only giving a conservative number, and with the rapid advancement of the space program, this number will gradually increase.

It would be good to wait for the first space elevator to be built, as the old saying goes, everything is difficult at the beginning, as long as there is the first elevator, although its power may not be so high, and the carrying capacity may not be so large, as long as it can be built, it can put aside the rocket and transport it to space at a staggering low price.

As for the rocket, Lao Maozi and the lighthouse country can play as much as they want, and the Chinese people still like to take the elevator, so they won't accompany them.

"How's the test going?" Luo Jia asked.

"It went well." Wang Zhiyu said excitedly: "Seven units have been tested, all of which have passed at one time, and the process of Nantong manufacturing plant is really amazing!" The test data for each engine is almost exactly the same, and I have never seen a product with such excellent consistency in my life in aerospace. ”

Wang Zhiyu was full of praise for the quality of the A1 engine, Luo Jia smiled and said: "The reason is not difficult to understand, first of all, because the company's mechanical department has manufactured the world's highest precision five-axis and seven-axis linkage machine tools, and the core strength of the machine tool industry comes from our ultrasonic motor, and now the motor we manufacture has far exceeded the harmonic geared motor of Neon Teijin Group." ”

"Secondly, because of the high-precision robotic arm and the 3D printer, the robotic arm can improve the quality of the final assembly, and the 3D printer is even more powerful, which can handle those complex and difficult components that cannot be completed by even a five-axis machining center."

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

Luo Jia said with a smile: "I have to correct it, our 3D printing technology is not suddenly powerful, unless you are irradiated by gamma rays and suddenly become a Hulk, or be bitten by an ancient spider and become Spider-Man, otherwise in this world, no one will suddenly become powerful." ”

"Wen Chengling is the world's top laser expert, and his addition allows us to solve the technology required for ultraviolet laser hybrid lithography machines, and the laser technology used in lithography machines continues to derive, which is the laser precision engraving required by 3D printers."

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

"At present, the 3D printing department is still expanding rapidly, and I believe that in a few years, we will be able to use 3D printing technology to print the entire launch vehicle, which will be no less than another great beginning of the industrial revolution."

Listening to Luo Jia's passionate words, Wang Zhiyu's heart was turbulent, 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 came to the harvest season.

All the previous R&D achievements are the foundation of the company, and the company has grown rapidly on the foundation.

After the fright, everyone pondered carefully, in fact, 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.

And now when we look at the world, we find that Westerners are actually very lazy, very hypocritical, and have the smell of foxes that can smoke people to death, like a group of animals that have not fully evolved, so we call Westerners white-skinned pigs and dislike them in various ways.

From the foreign uncle to the white pig, the change in the middle is not because the West has changed, but because we have gradually completed the accumulation of industry and technology, and eventually, the gap will gradually disappear, and we will look at the world from the same height as the West.

Only after equality between people, what you see and feel will tend to be true, which is like the teacher-student love, or the love affair of subordinates to their superiors, modern psychology tells us that there is an element of power worship, and for example, if you go to Africa, the black girls will definitely live and die for what you like, which is also a phenomenon of power worship, one of the inherent attributes of human beings.

"There will be an engine test in the afternoon, do you want to take a look at it yourself?" Wang Zhiyu suggested to Luo Jia.

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

……

The A1 engine is laid flat on the machine, the nozzle is facing the desert outside, and the mechanical structure itself is connected to a dense network of pipes and cables, which in turn are connected to the central computer in the control room.

The data on the screen showed that the A1 engine weighed a total of 1.03 tons, and everything was ready for the tests to begin.

Yes, the A1 engine, which can reach the 550-ton level with thrust, has a total weight of only a little more than a ton, while the same liquid oxygen methane engine, Lao Maozi's RD-171 has a thrust of 800 tons, and at the same time, it weighs nearly eleven tons, which is more than ten times heavier than the A1 engine.

The slender and slender fuselage has a dull gray-black glow, and the reason why the A1 engine is so lightweight is mainly due to the materials department, super strong carbon fiber and graphene are not only lightweight, but also strong and resistant to heat and corrosion, far exceeding the current synthetic metals.

Unless the legendary alloy artifact triple titanium alloy comes out, the graphene and carbon fiber of Xingchen Technology are destined to be incomparable.

As for the slender and slender engine structure, it is mainly designed for multi-engine joint operation.

The so-called multi-machine joint operation, a simple and crude explanation, is the meaning of tying a row of engines together.

In principle, it is not difficult to combine multiple engines, but the difficult thing is the linkage system, through complex calculations and precise control, to control each engine to put the vector nozzle, towards the most correct direction, without even a millimeter of error, the injection system perfectly controls the release and weakening of thrust, these technologies are the most difficult.

The first test is the vector nozzle and various static parameters, from the control room to send a command, the nozzle continues to rotate with the command, driven by a micro ultrasonic motor, quickly adjust the angle, while the computer collects engine data, and the original data is checked.

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

Wang Zhiyu said, pointing to the biggest red button on the console.

Luo Jia paused slightly, then stretched out his right hand and pressed it down gently, and after a short damping sensation, there was a snapping sound in his ears, followed by a loud bang outside the control room.

The beautiful blue light of the red infrared layer of the inner core suddenly roared out, like a sharp arrow of the god of fire shot into the desert, tearing through the air, letting out a beast-like roar, burning all the matter around the flames, causing the water molecules in the air to vaporize instantly.
