I ask you to build tractors, but you build rockets?

Although he is not the oldest, He Gong has the most say in YF100.

So when it was his turn, everyone fell silent.

He Gong was still looking at the technical manual in his hand. He put it down when he heard someone calling him, stood up and bowed to everyone.

"First of all, I apologize on behalf of the project team. No matter how the K120 came about, it is not as good as others. We have used it for 15 years, but we still have not achieved the world's advanced level."

"You can't say that. The YF100 indicator has completely met expectations. I can only say that the K120 is too awesome."

"That's right, we all start from scratch, unlike others who have countless experiences."

"..."

As soon as this statement came out, everyone quickly tried to dissuade him, but He Gong just shook his head.

"It is a fact that YF100 has fallen behind, and it is also a fact that K120 is advanced. My opinion is: Since the RD120 was used as a reference when designing, it doesn't hurt to copy the K120 now.

However... YF100 remains unchanged, there is no need to improve it. "

Tang Weitian heard the implication and suddenly thought of something:

"You mean YF480?"

"Now its name should be changed to YF130, and its derivative YF135."

He Gong slowly opened his mouth and everyone immediately remembered these two projects.

To be precise, they haven't established a project yet.

At present, the space agency is already planning the Long March 5, and YF100 is also preparing for this. It is too late to make changes at this time, and it is not necessary.

However, future heavy- and even super-heavy rocket engines, with internal codes YF130 and YF135, are still under review, and are also liquid oxygen and kerosene rocket engines.

It is most suitable to use K120 to improve future heavy-lift rocket engines, and there is sufficient time to absorb technology.

After Tang Weitian presided over the meeting, he sent the results back to the Sixth Academy, and did not receive a reply until the next night.

The Sixth Institute overall has a positive attitude towards acquiring K120 technology, is willing to engage in commercial cooperation with private enterprises, and is inclined to purchase prototypes and production licenses.

In other words, it’s the same as acquiring foreign company technology, buying your products, but you must teach me.

However, the Sixth Academy is much more cautious and requires the inspection team to stay in Xinyuan Town until the Xinyuan-1 rocket is launched before making a final decision on whether to purchase it.

This is a tradition in China. No matter what good thing it is, it must be for your own use before I buy it. Otherwise, no matter how nice it sounds, I won’t buy it.

Of course, in the eyes of senior researchers, K120 is very reliable, but sometimes the superior leaders who actually do typesetting must consider more and not let anything go wrong.

So Lin Ju received a request from the Sixth Institute to continue visiting the factory and approved it immediately.

In his eyes, this is nothing more than a embarrassment to him, it's just a gift.

With so many people from the Sixth Hospital going to that stop, is it okay for the technical staff in the factory to ask a few questions and communicate with each other?

When producing engines, ask what needs to be paid attention to and what experience you have to avoid pitfalls. I would be embarrassed not to tell you, right?

If so many talented people don't make good use of it in the factory, they are really ashamed of this hard-won opportunity.

Guo Shen also knew this very well. He led his factory and the additional technical staff recruited during this period to hold technical seminars from time to time, and even brought the inspection team along with him.

It is known as listening to the opinions of outstanding units and exchanging technical blind spots.

The inspection team didn't refuse. After all, it wasn't too much of a secret, and they wanted to find something to do for themselves.

With such rapid gains, the rocket was assembled nine days earlier than expected.

Just stand it up and turn on the power and check it again, and then you can add fuel and launch.

Although the diameter of 2.5 meters is relatively small among rockets, it is not small in terms of perception. After all, it is almost as high as a floor.

The rocket was painted with the unit names and logos of Nanjing Nanjing Institute of Technology and Xinyuan Town Tractor Factory in the assembly workshop, and then the four characters "Xinyuan No. 1" were written vertically along the rocket body.

Finally, the factory employees, the participating support staff of Nanjing Institute of Technology, and the inspection team took a group photo together holding banners:

"The final assembly roll-off ceremony of Xinyuan No. 1 was a complete success!"

Also present were specially invited photographers from the province and Taiwan, who specially took all-round shots of the lying rocket.

The reporter who had interviewed Lin Ju before was also present and was dumbfounded looking at this decent rocket.

He actually had a bad impression of this arrogant tractor factory before, and he just came here to complete the task and go through the motions.

Who knows how long it has been until a rocket is actually built?

The real rocket is swung here, and you can't even think about it.

That day, when the provincial and municipal leaders heard that the tractor factory had actually built a rocket, they almost jumped up in shock.

In the traditional impression, aerospace has always been a high-end industry. It seems that it can only be handled at the national level. No one has ever heard that private individuals can engage in aerospace.

The next day, leaders of all sizes went to the tractor factory to see what kind of rockets the private enterprises had.

Uncle Wan and the town leaders, who were the first to congratulate him, had to accompany the higher and higher superiors one by one before they could watch for an hour.

In the evening, the provincial station spent several minutes reporting on Xinyuan No. 1 and the impact of major leaders coming to inspect it.

Local leaders don't pay much attention to whether the rocket can be successfully launched in the end. After all, this is China's first attempt at private aerospace, and it would be great if it can be built.

The reports were full of praise, especially when I heard that the engine was advanced, and they were even more complimentary.

On the Internet, several video platforms have not yet declined, and the video of the final assembly of Xinyuan No. 1 is also spread everywhere.

On some TV and some cool websites, rockets and popular online dramas have rushed into the popular rankings, proving that there are still many people paying attention to aerospace.

Lin Ju was tired of the well-known Vs on blogs, so he simply ignored them and turned to the video platform to see how the reaction was.

Clicking on the most popular rocket assembly video on a certain TV station, there are already thousands of comments below.

"No, I thought it was just talk. Is the tractor factory serious?"

"The engine test run has been released, isn't the rocket body simpler? And to put it bluntly, this rocket is at the level of the Long March 1, and it doesn't deserve much attention at all."

"Private aerospace companies are so unbelievable. They built a rocket in more than a month, which is faster than the space agency."

"What's the point of just looking at the appearance? The key is to be able to fly without exploding. Aramco has not even succeeded in private space flight, okay?"

"This 120-ton engine is almost exactly the same as the YF100, and there are people from the Sixth Academy in the photo. Isn't it a company under the aerospace agency?"

Compared to blogs, the comments here are much more normal and less aggressive.

After browsing several video platforms in a row, Lin Jucai heard that Tieba forums in this era have not yet declined, and various experts are still full of useful information. There must be a lot of enthusiasm for Xinyuan No. 1, so he logged in to Tieba to read news about the aerospace sector.

What surprised him was that the entire aerospace forum was basically discussing Xinyuan No. 1. However, at this time, the forum was filled with great people. Many of them were solid technical posts, analyzing the technical parameters and engines of Xinyuan No. 1. Some of them were still professional. Extremely high.

The reason is actually very simple. In the past few years, the Chang 5 has not been successful. The largest rocket in China is the Chang 3B. Everyone has long been tired of the old rockets that have lasted for more than ten years. The space station only has one or two simple cabins. There's really not much to discuss.

The sudden appearance of private aerospace attracted the attention of Tieba almost immediately. In fact, it has been gaining popularity since the K120 engine test run, but Lin Ju had not paid attention to it before.

Lin Ju suddenly became playful and posted a message.

"I am Wang Ergou, the guard of the tractor factory. Rumor has it that Xinyuan-1 will be launched at the following address on August 26. If you want to watch it live, come quickly. There are three diversion trough seats.

Address: Laoliu Village, Xinyuan Town..."

…

"Slow down, slow down. I told the driver to drive slower. What should I do if it breaks down? The sensors are precious."

"Old Zhou is so worried. When the satellite went up to the sky, the overload and vibration of the rocket were not stronger than now? If it doesn't work after a few times, can it still go up safely?"

Sitting in the satellite transport truck on the road, Tong Peiqiang and Zhou Rui looked at the fixed satellite and kept bickering along the way.

"Oh, the time is still too tight. If the space agency takes longer to coordinate the two solar cells, we can be sure that it will take five years. 50 days is too short."

"It's almost ready. Half of the 400 kilograms are batteries, only 65 kilograms are radiation detectors, and the rest are for cameras and a seed chamber. It's more than enough to complete the experiment in 50 days.

This time, why don't I also get 20 SCI articles? The upgrade of our school depends on it! "

The satellite was packaged in a special transport box, but the two of them put their hands on it from time to time and couldn't bear to leave it for a moment.

This satellite has been officially named Nanxin-1. It rolled off the assembly line almost at the same time as the rocket assembly, and then set off immediately.

The launch site has been selected, and it is on a plain in Xinyuan Town.

After launching here, it will pass through sparsely populated mountainous areas and forests after takeoff, and the final landing area will be in Nanyang, minimizing the risk of crashing.
