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

So when it was his turn, everyone fell silent.

He Gong was still looking at the technical manual in his hand, and when he heard the shouting, he put down the booklet, 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. It has taken us 15 years, but we still have not reached the world's advanced level. ”

"You can't say that, the YF100 indicator fully meets expectations, and it can only be said that K120 is too demonic."

"It's just that we all started from scratch, and there are so many experiences like others that I can't count."

“……”

As soon as this remark came out, everyone hurriedly dissuaded him, but He Gong just shook his head.

"It's a fact that the YF100 is outdated, and it's also a fact that the K120 is advanced, and my opinion is: since the RD120 was used as a reference in the design, it doesn't hurt to copy the K120 again.

But...... The YF100 remains the same, and there is no need to improve it any more. ”

Tang Weitian heard the meaning of the words, and suddenly thought of something:

"You mean the YF480?"

"Now it should be renamed YF130, and the derivative YF135."

He Gong slowly looked at the opening, and everyone immediately remembered these two projects.

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

At present, the space agency is already planning the Long March 5, and the YF100 is also preparing for this, and it is too late to change it at this time, and the necessity is not great.

However, the engines of future heavy-duty and even super-heavy rockets, with the internal code names YF130 and YF135, are still being demonstrated, and they are also liquid oxygen kerosene rocket engines.

The K120 is most suitable for improving the future heavy rocket engine, and there is also plenty of time to absorb the technology.

After presiding over the meeting, Tang Weitian sent the results back to the Sixth Academy, only to receive a reply the next night.

The Sixth Academy as a whole has a positive attitude towards the acquisition of K120 technology, is willing to cooperate with private enterprises for commercial cooperation, and tends to purchase prototypes and production licenses.

That is, just like when you got the technology of a foreign company, buy your products, but you have to teach me.

However, the Sixth Academy was much more cautious, and asked the inspection team to stay in Xinyuan Town until the launch of the Xinyuan-1 rocket before finally deciding whether to buy it.

This is a tradition in China, no matter what good things are, they must be bought by you for your own use, otherwise you won't buy it no matter how good it sounds.

Of course, in the eyes of senior researchers, the K120 is very reliable, but sometimes the superior leaders who really typeset must think more and not fall behind.

So Lin Ju received a request from the Sixth Academy to continue to inspect the factory, and then immediately approved it.

In his eyes, this is embarrassing for him, it's just to send benefits.

With so many people from the Sixth Academy, the technicians in the factory asked a few questions, and it was no problem to communicate, right?

When producing engines, ask where you need to pay attention and what experience you can avoid pitfalls, and you are always embarrassed not to say, right?

So many big bulls don't make good use of it in the factory, it's a shame to be ashamed of this hard-won opportunity.

Guo Shen also knew this, and took the factory and the additional technical personnel recruited during this period to hold technical seminars from time to time, and also pulled the delegation together.

It is said to listen to the opinions of excellent units and exchange technical blind spots.

The delegation did not refuse, after all, it was not too secret, and it was also to find something to do for themselves.

With such a rapid gain, the rocket was assembled 9 days earlier than expected.

As long as you put it up and check it again, you can refuel and launch.

Although the diameter of 2.5 meters is a small category among rockets, it is not small in terms of senses, after all, it is almost one story high.

The rocket was painted with the names and logos of the units of the South Machinery Institute and the Xinyuan Town Tractor Factory in the final assembly workshop, and then the four big characters of "Xinyuan No. 1" were written vertically along the rocket body.

Finally, the employees of our factory and the supporting personnel of the South Institute of Machinery and Technology participated in the inspection, and the delegation took a group photo with banners:

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

Also present were specially invited provincial photographers, who deliberately took all-round shots of the rocket lying horizontally.

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

He actually had a bad impression of this outrageous tractor factory before, and he just completed the task and came over to go through the motions.

Who knows how long it will take to really build a rocket?

The real rocket swings here, and you can't accept it or not.

On that day, the leaders of the provinces and cities heard that the tractor factory had really built a rocket, and they almost jumped up in shock.

Aerospace has always been a high-level industry in the traditional impression, and it seems that only the national level can do it, and no one has ever heard of private people being able to engage in aerospace.

The next day, leaders of all sizes ran to the tractor factory, wanting to see what the rockets of private enterprises looked like.

Uncle Wan and the town leaders, who were originally the first to congratulate, had not been watching for an hour, so they had to accompany their higher and higher superiors one by one.

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 do not pay much attention to whether the rocket can be successfully launched in the end, after all, this is the first attempt of China's private aerospace industry, and it is remarkable that it can be built.

The reports are all praises, especially when they hear that the engine is advanced, and they are even more fiercely touted.

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

In a certain TV and a certain cool website, Rocket and the popular online drama rushed to the popular ranking, proving that there are still many people who pay attention to aerospace.

Lin Ju was tired of the well-known big V on the blog, so he simply ignored it and turned to the video platform to see how the reaction was.

Click on the most popular rocket assembly video in a video station, and there are already thousands of comments below.

"No, I thought it was just talking, the tractor factory is real?"

"The engine test has been released, isn't the arrow body simpler? And to put it bluntly, this rocket is the level of the Long March-1, which is not worth paying much attention to at all. ”

"Private aerospace is too against the sky, and it takes more than a month to build a rocket, which is faster than the space agency."

"What's the use of just looking at appearance, being able to fly without blowing up is the king, and Aramco's private spaceflight has not been successful."

"This 120-ton engine seems to be almost identical to the YF100, and there are people from the Sixth Academy in the group photo, it won't be a company under the space agency, right?"

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

After swiping several video platforms in a row, Lin Ju sounded that the post bar forum of this era has not yet declined, and all kinds of gods are still full of dry goods, and there must be a lot of heat for Xinyuan No. 1, so I logged in to the post bar to see the news of the aerospace sector.

To his surprise, the entire aerospace version is basically discussing Xinyuan No. 1, but at this time, the post bar is full of people, many of them are real technical stickers, analyzing the technical parameters and engines of Xinyuan No. 1, etc., some of which are extremely professional.

The reason is actually very simple, in the past few years, Chang Wu has not succeeded, the largest rocket in China is Chang Sanyi, the old rocket that has lasted for more than ten years has long been tired of everyone, and the space station only has one or two simple cabins, and there is really not much to discuss.

The private aerospace that suddenly appeared almost immediately attracted the attention of the post bar, in fact, it has been hot since the K120 engine was tested, but Lin Ju had not paid attention to it before.

Lin Ju suddenly became playful and also made a post.

"I am the tractor factory doorman Wang Ergou, the grapevine news on August 26 Xinyuan No. 1 will be launched at the following address, want to watch the scene quickly, there are three more diversion troughs.

Address: ...... of Laoliu Village, Xinyuan Town"

……

"Slow down, slow down, I said the driver drive slowly, what should I do if it's broken, the sensor is expensive."

"Old Zhou, are you worried about the fart, when this satellite is in the sky, the overload and vibration of the rocket are not stronger than now? If you can't do it in a few clicks, can you still go to heaven safely? ”

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

"Heck, the time is still too tight, if the time is longer to coordinate two solar cells from the space agency, so that it can be sure in 5 years, 50 days is too short."

"That's pretty much it, half of the 400 kilograms are batteries, only 65 kilograms are radiation detectors, and the rest of the space is given to the camera and a seed chamber, which is more than enough to complete the experiment in 50 days.

This time, why don't you have to brush up on 20 SCI articles? Our school's upgrade depends on it! ”

The satellite was wrapped in a special transport box, but the two of them put their hands on it from time to time, and they were reluctant to leave for a moment.

The satellite, which has been officially named Nanxin-1, rolled off the assembly line almost simultaneously with the final assembly of the rocket, and then immediately set off for shipment.

The launch site has been chosen, on a plain in Xinyuan Town.

Launched here, after takeoff, it passes through sparsely populated mountains and forests, and finally lands in the South Seas, which minimizes the risk of crashing.
