Here comes a concept that needs to be explained, thrust and push ratio.

The greater the thrust of military aviation engines, the higher the requirements for raw material quality and manufacturing process. The higher the push ratio, the higher the technological content, and the more advanced the engine performance, just like the United States' engines have always been pushing higher data, while Russia's engines have the thrust leading all the way.

So speaking, the f118-ge-110 afterburnerless turbofan engine of the B-2 stealth bomber is not actually the most advanced engine in the world, because it appeared to accommodate the size and stealth needs of the B-2, depending on the size and fuselage design of the B-2.

The b-2 has a flying wing layout, and in order to stealth, all fuel tanks and mountings are in the fuselage. Although the fuselage is already relatively thick, in order to accommodate up to 22 tons of ammunition and 90 tons of fuel, the internal space of the fuselage is very tight. You should know that the data of 22 tons of ammunition is close to the maximum loading of b-52.

The size of the f-118 is relatively small, with a length of only about 2.5 meters, so that the b-2 can stuff four f-118 engines into the short fuselage.

However, b-2 uses f-118, and it is not only the diameter that compromises, because even f-119, f-110, f-101 is less than 1.2 meters in diameter; what compromises is the inherent shortcomings of all the built-in and flying-wing layout of the B-2 ammunition and fuel.

Relatively speaking, the f-119 is the most advanced engine in the world. Its thrust reaches 156 kiloN and its push ratio is as high as 11.7. However, it is a specially developed engine for the US f22. It was officially approved for the initial use of the US Air Force in September 2002. So at present, the f-118 is still the king of aircraft engines. Although the thrust is not large, the push ratio is incomparable to all other engines. Even Russia cannot catch up with its push ratio at this time, let alone Europe and China...

Because the push ratio of Kunlun engines in China is only a pitiful 7...

Let’s popularize engine knowledge here. The original intention of the Kunlun engine independently developed by China was to upgrade. Unfortunately, it was not timely. Although the "Kunlun" that took 18 years to arrive late reached the peak of the turbojet engine, it has lagged behind the pace of the times. Because in 2002, the US F-22 was born, which forced the Chinese Air Force to also start to equip a large number of third-generation aircraft. The completely backward Kunlun engine was not attracted by the Chinese Air Force at all. So until Chu Fei was reborn, there was no order. If it weren’t for the Taihang engine that appeared at that time, China’s engine research and development would have been...annihilated!

But although the data of Taihang engines are very beautiful, the push ratio is barely 9, which is not comparable to that of European engines, let alone Russian and American engines... It is not of the same level as that of Russian and American engines!

Think about it, even five years later, China's engine technology still cannot catch up with the United States. It is not difficult to explain what kind of mentality will it be when the country knows that Chu Fei has two F-118s here? What is the purpose of relocating 301? If possible, they even dare to move all AVIC and Shen Hang here!

So it is even more difficult to explain why Mr. Wu Daguan and others were shocked, because whether it was Kunlun or Taihang, it was finally unsheathed after eighteen years of hard work. Moreover, Kunlun engines are still being developed, not to mention Taihang engines that do not even have a shadow. China is still blank in the engine field so far... But here Chu Fei has taken out the drawings directly, and then manufactured and assembled them in one go, and then... it is a finished product that is more advanced than most engines in the world?

And the most important thing is that the technology of this engine is completely different from that of the United States and Russia. Not only the design concept, but also the materials, but even the assembly technology belongs to another new concept, which is what Mr. Wu Daguan said before... Children play house! But after two or three days of repeated tests, they were shocked to find that the performance of this engine is outrageous, and whether it is the function ratio or other index, it is far beyond the f-118 used by the B-2 stealth bomber!

As soon as this news came out, it immediately caused a huge earthquake in a circle in China. Then, because Qingcheng Group was still under construction and the testing conditions were limited, Qingcheng-1 was quickly escorted away by a "special team". It needed to go to a more formal place for more stringent and accurate tests. Of course, this matter had nothing to do with Chu Fei. All he had to do was to get a pretty old engine, and then as for other details and tests, you can do it, anyway, I'll sell it for money.

Perhaps many people will be worried that Chu Fei has handed over all the drawings, and the country can easily steal information about this engine, so how can he sell it for money?

Of course not!

In fact, it is definitely not just you who think so. Someone has taken action first. They copied Chu Fei's drawings, then made them the same, and then installed and spliced ​​them according to the same steps. The result was heavy. Although the engine was made exactly the same, it was directly blown into pieces during the test!!

As mentioned earlier, the performance of the engine depends entirely on the material. The reason why China cannot make a good engine is because our material technology is far from standard. We cannot achieve many technologies that the United States and Russia can do, so our engine push ratio is directly behind several levels. This reason is understandable when Chu Fei said that Chu Fei is not a fool. He just replaced the core parts produced outside with a few parts produced in the agency during quality inspection, so...

Of course, it is okay to use external parts for unimportant parts, but the core position must not be careless, because this little difference has caused the decades of gap between China and the United States and Russia!

The result is that these people want to steal and copy Chu Fei's engine technology? Well, wash and sleep. Without the core materials processed by the machine workshop in Chu Fei's demon refining pot, even if they get the full set of drawings, they will have no effect. Moreover, they have not even figured out the design principles of this set of engines yet, and this project is not a matter of one day, two days, one month or two months! Even if they understand the principle, they will still worry about the production of the core materials, because they have no choice except Chu Fei can produce them!

They can try everything Chu Fei is forcibly snatching everything? Who are Chu Fei afraid of now?

Chu Fei thought very clearly. No matter how you do the R&D center, no matter which one you move over, no matter how you build a large piece of land behind, no matter how you do it, it has nothing to do with me. I don’t pay for those equipment, I don’t register those assistants, and I don’t pay those security guards… What I want to manage is one acre of three-point land here, and I am responsible for my workers. As long as you don’t cause trouble for me, you can do it.

So Chu Fei doesn't care about these things now, because he is already busy again. After the New Year, the girls gradually come back to Wuhan. Since it is a new beginning of the New Year, of course he must seriously start taking them to practice. Then there is one more thing: he needs to find someone to go through the transfer procedures of his sister Chu Lian and transfer her to a nearby high school. In addition, the transfer of work for his aunt Chu Li is also underway. As for his mother He Peiling, Chu Fei plans to let her manage the large and small businesses of Qingcheng Manufacturing Group for him and become the president of the group.

Of course, this position may be a bit too advanced for He Peiling, so while the factory is still resting, she has already started to "intern" with Xiahou Zhu and the others. If Xiahou Zhi hadn't really been unwilling to do anything anymore, Chu Fei would have planned to let her be the vice president to help her mother, and in the end, let Xiahou Zhu serve as the part-time...

But these are just small things. The reason why Chu Fei is really busy is that he is now... famous!!

Because Chu Fei turned Mr. Wu Daguan and other pioneers of the Republic into young and strong young people, and even their families, I won’t talk about how much sensation this incident caused in Beijing. At least no one at the top of the country has heard of his name now. So shortly after Qingcheng No. 1, Zheng Fan of the Dragon Group and the others took the initiative to find the door... Of course, they did not come to cause trouble, but sent Chu Fei his Dragon Group ID.

Chu Fei said before that he returned to five years ago through the Kunlun Mirror, and five years later his identity was a member of the Dragon Group.

Although it was difficult for the country to believe this at first, when Chu Fei directly made the engine of the B-2 stealth bomber, especially after he took out two, the people above immediately determined that the loss of the B-2 at Anderson Air Force Base in Guam, the United States was actually Chu Fei's hand. Everyone was shocked. So, wouldn't Chu Fei have the best stealth aircraft in the world? But more importantly, Chu Fei actually has the ability to steal things in front of people!!

Then Chu Fei took out some drawings to create Qingcheng No. 1, which proved the country's conjecture and at the same time verified Chu Fei's words. If he had not come back five years later, how could Chu Fei understand these engine knowledge? Because his current identity is just a high school student who has not even attended college.

The fact now is that Chu Fei not only possesses magical power, but also masters the knowledge urgently needed by the country, and is even more likely to know the whereabouts of the top ten ancient Chinese artifacts!

What's more, Duan Lin, who returned to the Dragon Group after the New Year, did not hide her whereabouts at all, and directly confessed to the organization that she had become Chu Fei's woman...

So no matter why it is, it is inevitable that the country will re-recruit Chu Fei into the Dragon Group, so Zheng Fan and the others came, but Zheng Fan is actually just a test. What they want to know is... what exactly Chu Fei wants?

What do you want?

Chu Fei's answer is very simple, "Freedom and cooperation!"

Everyone understands freedom, but cooperation? What is this? Chu Fei gave an explanation later. Zheng Fan and the others were stunned... No one can interfere in anything Chu Fei did in the name of the country! This is the freedom Chu Fei wants, and cooperation means that the country can send people to follow Chu Fei, provide convenience and profit from it, just like the current Qingcheng Manufacturing Group, the country takes Qingcheng No. 1 to study, and Chu Fei said nothing.

Of course, Chu Fei was not stingy, because his purpose was to make the country strong and make China rise! But Chu Fei was tired of the model of taking the country as the dominant position before rebirth, especially when he sent Nangong Yue to him, this was not possible, that was not possible, and that was not possible. Then he had to keep running around for this and that of the country.
