Among the world's major nuclear fusion research facilities, the strongest in theory is ITER, which is led by international cooperation, which intends to bring together the world's strongest forces to launch an attack on controlled nuclear fusion.

However, it is needless to say which countries are "international", and China tried to join it, but after finding that it was also being used as a money bag, it reversed course and began to support the domestic independent EAST project.

Founded in 2003, EAST was supposed to be the world's most advanced and advanced controlled fusion test facility by the time of the Lin Ju crossing, and the Academy of Sciences in Hui Province has announced that it will be commercially available by 2035.

Regardless of whether EAST can go through or not, there is nothing to say about the scientific content of one of the many advanced nuclear fusion research facilities, and it is not necessarily a loss to be able to participate in it.

As for the particle accelerator, Lin Ju knows that after 2020, the country has proposed several large-scale particle accelerator plans, each of which has surpassed the LHC, but I don't know why the construction has not started for a long time.

However, this at least shows that the state does not reject the construction of such large-scale scientific facilities after economic development, and as long as the timing is right, it should be possible to push it forward.

Lin Ju: "EAST is now the best controlled fusion device in the world, and I think it would be a bit more important if we let Cheng Gong pass.

Can we find theoretical results in this book that are not too shocking, but have sufficient weight? ”

Cheng Nankai: "......"

Ye Changsi: "Maybe, in fact, without the assistance of experiments, this may be closer to conjecture, but it should be enough, it will take a little time."

It is not necessary to have a small procession, it is enough to be able to obtain some actual data from the EAST runtime, and with this data, we can build a complete controlled fusion model based on future knowledge, and it will be much easier to carry out our work in the future. ”

……

"The YF90 gas generator was successfully tested in Chang'an, and the chief engineer revealed that the prototype has entered the manufacturing stage."

Zhou Qingfeng saw the latest post that was reprinted, and subconsciously wanted to reply, but when he touched the keyboard, he stopped abruptly and left the stool dejectedly.

He still remembers that it was an ordinary afternoon, and he looked at the clouds at sunset and thought nonsense when he hadn't chatted with "All the Way" for two days, and even ignored the past when exchange student Huang Xiaobin said that her mother was going to celebrate his birthday.

When Zhou Qingfeng was wandering around the world, the director of teaching and two people in gray suits walked into the classroom and took the junior high school student into the car.

The young Zhou Qingfeng learned the elusive security bureau style for the first time, and after sitting on the interrogation chair in a confusion, the old aunt opposite made him break the defense with a word.

"Zhou Qingfeng, have you ever had a relationship with a person with a QQ nickname called 'All the Way Scenery'?"

Zhou Qingfeng nodded blankly.

"Did you know that you're talking to an IAA spy who knows a lot of secrets from your mouth?"

The stunned Zhou Qingfeng was put in front of a piece of information, and he picked it up without being handcuffed, and the first thing that caught his eyes was the words "Niu Aihua".

Cows love flowers? Cows love flowers?!

As the "Z God" who mixed up with the aerospace military forum early, he naturally knew what "50W" was, and soon understood what he had done.

Zhou Qingfeng, who was immediately struck by lightning, had no idea of resisting, and the Security Bureau didn't want to give a junior high school student a long memory.

They printed out all the chat records between Zhou Qingfeng and Niu Aihua, asked whether each sentence was Zhou Qingfeng's reply, and asked him to write the psychological activities at that time and sign after each one.

You must know that there are a lot of ambiguous methods carefully thrown by Niu Aihua in these chat records, Zhou Qingfeng didn't dare to lie here at all, so he had to follow the requirements of the Security Bureau.

By the time the thick transcript was finished, Zhou Qingfeng had already cut out two large holes in the thick sneaker insole.

But this is not the limit, the photo of Niu Aihua he secretly took was also taken out and asked to elaborate on all the details of the day, it is hard to imagine how much psychological shadow it caused to a twelve-year-old child.

After being severely trained by the old man, Zhou Qingfeng has been deprived of the right to speak on the Internet, and all the posts of "Z God" have been deleted, and he can only surf the Internet without sending any reply.

Zhou Qingfeng was uncomfortable enough just like this, and what was even more uncomfortable was that he also knew that Niu Aihua was Huang Xiaobin's mother......

Zhou Qingfeng, who has nothing to love once a day, sighed unagedly and continued to browse the forum posts.

When Xinyuan was stealing the limelight, the space agency did not fall behind, and the results began to pour out.

The gas generator of the 220-ton hydrogen-oxygen engine has been successfully manufactured, which is one of the core components of the engine, indicating that it is about to enter the prototype trial production stage.

It's just that because of the poor performance of YF77, Zhou Qingfeng doesn't think that YF90 can succeed quickly, on the contrary, he thinks that YF135 has better prospects.

As a split supercharged single-burner version of the YF130, the YF135 is even less news than the YF90, and the Sixth Academy seems to have forgotten about the YF135 after the successful research of the YF130.

Of course, this is not the case.

Chang'an, rocket engine manufacturing base.

One of the two stations on the test bench was occupied by a medium-sized engine, and a few seconds after its combustion chamber began to emit white fog, a bright orange tail flame erupted from the nozzle, creating a series of Mach rings.

Experienced workers can know that the thrust generated by it is about 300 tons just by the vibration under their feet, which should not be much different from the expected figures.

The one that is being tested is naturally the next generation of reusable high-thrust rocket engine of the Space Agency-YF135.

The 360-ton single-combustion chamber liquid oxygen kerosene rocket engine, the reserve power of the new Long March 5 and Long March 9, is a cheap and reliable reusable rocket power.

This was the first prototype to be used for ignition testing, and although the rocking system and piping design were not yet reusable, at least the thrust was up to par.

Although the YF130 technology is mediocre, it allows the Sixth Academy to have the ability to design and manufacture a real giant rocket engine, and the progress of YF135 is much faster than expected, and increasing the pressure of the combustion chamber is not unreliable as imagined.

The engine went well, but the development of the Long March 5 and Long March 10 that matched it ran into some trouble.

The problem lies in the rocket body, first of all, the Long March 5, its six-meter diameter arrow body can plug seven YF135, but when doing the sample arrow irrigation and swing test, it was found that the high strength is not enough, and the 2600 tons of thrust of the seven YF135 is too large, and the tremor caused by it is probably not small.

The Long March 9 is similar, the 11-meter-diameter rocket body has to be recovered, and the take-off thrust is expected to exceed 10,000 tons.

There are two solutions: strengthen the body or increase the diameter.

Needless to say the former, if it is the latter, the diameter of the Long March 5 rocket body will be expanded from 6 meters to 7 meters, and the arrow body of the 9th will be expanded from 11 meters to 12 meters, which will naturally reduce the height of the rocket and enhance the anti-vibration ability, and the technical problems are not too big.

However, both options will increase the cost of the rocket, the diameter of the rocket body will be changed, the production equipment will have to be adjusted, the height of the first stage of the Long March 5 will be reduced by about 20 meters, and the structure of the rocket body will almost be overturned.

Both are technically possible, but the cost increase of both solutions is a headache.

Fortunately, the expected first flight date of the Long March 5 is before 2020, and there is still some tangled time.
