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

"If Mr. Qian said so, then I am really happy. The H1 space shuttle is of course different from the past. The cost of each launch is very low, and it can be launched once in as little as a week, usually once every half month, and press once Counting 6 people, it’s no problem to send 50 people up this year.

It is a pity that Xinyuan only has one professional astronaut, Deng Lei. The commander still needs to be an outstanding professional; there should even be two professional astronauts. The commander and deputy commander must be familiar with the operation of the space shuttle. . "

"So many!" Captain Li sighed with emotion. The space agency has only conducted five manned launch missions in the past 10 years, so the astronaut team has so few talents.

With less than thirty people, there are very few opportunities to go to heaven. Maybe some of them may retire and never go near space. What a pity!

If there was a space shuttle, everyone would surely have a chance and wouldn’t have to pass it by again and again, right?

I don’t know if he was feeling too much, but Captain Li suddenly said:

"To tell you the truth, last week I went to the Ulan Hashan base. Didn't you put a simulation cabin there for convenience? I not only went to see the H1, but also went to drive it on the spot. To be honest, it feels much better than sitting in a spaceship. I think you can really feel the sense of mission when you drive it through the atmosphere."

Lin Ju's heart moved, and he smelled more than just emotion in these words.

"Captain Li Wei, Xinyuan has obtained the qualification to participate in the national aerospace project. If the manned space project is also included, then Xinyuan also has the ability and confidence to send a group of astronauts into space to increase our aerospace experience."

"This...should also be considered."

When Lin Ju walked out of the training center, he felt a lot heavier on his shoulders.

During the training break in the afternoon, he met most of the members of the astronaut team and revealed Xinyuan's ability to participate in manned space projects and send a large number of crew members to space in a short period of time.

At that moment, although the reserve team members did not move, their eyes seemed to have the blazing sun burning.

Who doesn’t want to fly 300 kilometers into space? Aren’t the ten years of training just for that day?

…

The aerospace exchange meeting ended, and only a few photos and carefully reviewed text reports were leaked.

The official media barely mentioned this kind of informal meeting, but various entertainment media retweeted it like crazy.

Why would they be willing to forward it? Because there are hot spots.

From the Xinyuan 2 to the Xinyuan 4 rocket, the parameters are as follows: 15,000 tons, the largest in the world;

The H1 space shuttle, H2 space shuttle, and nuclear thermal rocket engines are the obvious hot spots for speculation.

Besides, Xinyuan has already figured out how to brag for you. It’s a super space station, a nuclear-powered spaceship has landed on Mars, the technology is a hundred times more advanced than Aramco, and so on. It’s enough to write more than a dozen reports.

Since 2010, various conspiracy theories, conjectures, and shocking headlines have become popular in communication studies, and soon they appeared:

"Director Lin fights against Ma Yilong: landing on Mars within a year"

"Domestic nuclear-powered spacecraft engine: consumes less than a spoonful of fuel per second!"

"Liquid oxygen methane engine will create a new era of human spaceflight"

"The latest news about the H-20 has leaked, it will be an aerospace bomber"

"Xinyuan Aerospace monopolizes 40% of the country's support funds, experts say so"

"The world's largest and most powerful 380-ton liquid oxygen kerosene engine"

"Luo Yufeng: I'm sorry, Lin Ju, only Xiao Heizi can match me."

"..."

Wait, what happened to Guan Luo Yufeng?

It turned out that Lin Ju was bored browsing the blog, and when he saw that Luo Yufeng was still active, he gave her a like, and ended up being popular.

Seeing the ordinary and confident Sister Feng talking about herself as "very good, but a woman like me can't get enough", Lin Ju gave up after a while of forbearance.

This makes it clear that the more opportunities you give the trouble, the more trouble you get. Just pretend it doesn't exist, at least it's not Mu Zimei.

At the end of the exchange meeting, Xinyuan finally officially registered in the country.

Not only has it obtained the qualifications to access national launch missions, it can also apply for certain technical support as a private enterprise.

Does Xinyuan need technical support? have.

Extravehicular space suits have very high requirements on materials and processing techniques. The B-level base has equipment, but since it will not be completed until the end of June, there are not enough employees to start the equipment.

According to the plan, the current tractor factory will only retain about 100 people, and it will be used as a supporting production base in the future. The B-level base will be expanded to 2,000 people, which is barely enough.

From recruiting people to getting familiar with the job, it takes time even if you have an upgrade card.

Therefore, the manned project still has to rely on existing factories. Although space suits can be made, it is too laborious and is entrusted to the space agency.

Moreover, Huaguo Aerospace has carried out many manned space missions and has a lot of valuable information for reference. The spacesuits manufactured by Xinyuan can also help with adjustments.

After all, human lives are being sacrificed, so there is no shame in listening to the opinions of the veteran aerospace experts.

Of course the space agency agreed and was able to deliver on time, but the price was a little expensive: Xinyuan provided too many new technologies that required adjustments to equipment and raw materials, and the unit price was 55 million, no bargaining.

Lin Naju was very stingy and only bought three pieces, two for homework and one for spare.

When the B-level base has its own production capabilities, the cost will be only one-third of this at most.

But the space agency is not too little, because they have only bought three of them in the past ten years...

Speaking of aerospace science and technology, we should also be very grateful to Lin Ju, because manned spaceflight has always been in a state of "it is a good thing and quite good, but don't rush and take your time" at the central government. Although it is safe, it has little support. Go slowly.

Now that Xinyuan Aerospace has jumped out to disrupt the situation, the superiors finally felt a little bit of the urgency of the aerospace industry and decided to invest more resources into aerospace.

On March 14, a YF100K, a 125-ton reusable rocket engine with full flow of liquid oxygen and kerosene, wide range of thrust adjustment, and 30-degree pump backswing angle, was installed on a Y-9 transport aircraft and flew to the Eighth Hospital. Rocket factory.

The Sixth Academy reverse engineered the K120V reuse version as quickly as possible from the K120 technology, instead of improving on its own YF100.

Since being forced to launch the reusable engine project due to high pressure in November, the Sixth Institute has tried its best to read the technical information of K120, and then after a comparison, it was found that YF100 lagged behind in every aspect.

There is no need to use the technology of K120 to improve YF100. The design of K120 itself has no shortcomings. It is compact, powerful, reliable and simple. Any modifications are redundant.

Therefore, the Sixth Academy decided to take a huge turn and follow the path taken by Xinyuan, and study how to convert K120 into multiplexers, instead of just clinging to YF100.

The results are surprising. K120 is very suitable for reuse and requires almost no modifications. It feels like it is designed for reuse.

Its dry-to-mass ratio is very high, its specific impulse is excellent enough, its design is durable enough, and its swing angle is not small.

Improving the repeatable version on the basis of K120 seemed to come naturally. Three long test runs were conducted at the end of February. The improved version is still as stable as an old dog and cannot find any faults.

Tang Weitian still vividly remembers what he did to the Eighth Courtyard, isn't he trying to rush me? I'll ship the engine over now!

So the number YF100K was used, but it has nothing to do with YF100. They are completely two technical routes.

The Sixth Academy has figured out that YF100 does not need any improvement at all. On the contrary, K120 is a treasure.

Especially the K380, which is also a full-flow liquid oxygen and kerosene engine, was exposed by Androv. The Sixth Academy is now thinking: The technical parameters of the K380 are so similar to the K120 that they must have the same origin. So if we also improve on the K120, will it be the same? Can an engine of this level be modified?

Therefore, the project with the internal code name YF380 was approved by the Sixth Academy, and the 380-ton liquid oxygen kerosene engine was quickly studied.

As for the 220-ton liquid oxygen methane engine that Xinyuan has been reported to have tested?

The Sixth Institute ignored it because there is not much difference in performance between methane machines and kerosene machines, and they are not much cheaper.
