"There is no budget, but as long as there is a breakthrough, you will give it as much as you want. We don't have it, and we will find a way!" Zheng Yucheng also knew that Xie Kai suffered a lot of grievances when he went to buy the engine.

Especially now that the Pakistanis have released pigeons, all the pressure is borne by the Xie family and the son.

They said at the beginning that they spent money on aircraft engines.

If it weren't for making more than seven as soon as possible and selling it, it wouldn't have cost more than 200 US dollars to purchase 200 engines, which is not very advanced.

Zheng Yucheng knew clearly.

There was a sound of gasping underneath.

"In addition, the previous two projects will continue to be tested. At the same time, I hope everyone will integrate the core backbone technical forces. We will establish a new military engine project. The technical requirements for the thrust-to-weight ratio will be 10, the minimum thrust will not be less than 9.5, the minimum thrust will be 110 thousand nm, and the afterburner thrust will exceed 180 thousand nm." Zheng Yucheng announced the new project, which put the entire conference room in a dead silence.

Then there was an uproar.

"This is impossible!"

"We have a bad foundation."

"Even if we design it, we can't produce it, and the basic technology field cannot keep up with it at all."

"It's totally arrogance, and there's nothing that can be done."

...

Everyone thought Zheng Yucheng was crazy.

"Director Zheng, we all understand your mood. However, the current reality is also in front of everyone. It is completely in line with our national conditions if it is unrealistic to propose such technical indicators, which are completely inconsistent with our national conditions..." Sun Hong spoke with difficulty. "The J-9 project proposed too high technical indicators and could not keep up in all aspects, and eventually consumed a large amount of national funds and was dismissed. The J-8 at the same time has now been put into force and has become the main force of the new generation of the Air Force..."

A tactful reminder that the technical indicators proposed by Zheng Yucheng are too aggressive.

This is completely the kind of work style that proposed to "catch up with Britain and surpass the United States" in the 1960s, and it is completely unrealistic.

Sun Hong's words were already quite tactful.

"At present, we are not suitable for building such engines in China. Even if a large press is created, there is no way. The materials cannot keep up with the construction technology cannot keep up with it. In powder metallurgy, there has never been much breakthrough in China..." Jiang Chenyang also pointed out with a serious expression, "Instead of wasting funds, it is better to consolidate these funds and cultivate a team of scientific research talents."

"Only in the process of R&D, we can train the team more and lay a solid foundation. If we only make a lot of trouble on the basis, what can we do toss out?" Zheng Yucheng asked in reverse. "The 617 Factory has always been very conservative in developing tanks step by step... In the end, they sold thousands of tanks, but the profit was not as good as we sold hundreds of them."

The more advanced the thing is, the better the market can be sold at a good price and the better the market.

"People may think that the technical indicators of this engine are very high. Before, when we discussed it, it was also completely impossible. However, when we went to the Soviet Union, we got their most advanced aircraft engine drawing design..." Xie Kai said.

Everyone was stunned.

Zheng Yucheng is no longer surprised.

Although I don’t know where Xie Kai came from the drawings, and although the possibility of getting the drawings from the Soviet Union is not high, Zheng Yucheng would never believe that Xie Kai could draw this thing himself.

Anyway, I won't say it if I ask.

Others do not have Zheng Yucheng's perception, and Xie Kai is just a yellow-haired boy, so he is not reliable at all.

"It's useless just for structural design." Sun Hong smiled bitterly.

Xie Kai, Zheng Yucheng and others were too doting, and they had no idea that the sky was high and the earth was thick.

"What if there are technical requirements and instructions for each part, and even some new materials to support it?" Xie Kai asked.

"If the situation is really like this, the supporting facilities can keep up, and there is no problem with the materials. I dare to issue a military order. Within five years, the prototype can be ignited!" Jiang Chenyang stood up and patted his chest to assure.

With the assembly design drawings, technical requirements for details, and even raw materials supply, the prototype will not be a problem.

After all, the prototype is only used to verify the technology, and it does not consider the service life, etc., and the ignition is successful, test thrust and other data, which is not a problem at all.

"We will provide these technical information here as soon as possible." Xie Kai said, "Let's talk about some specific situations of this engine first."

Xie Kai was forced to no avail.

If the J-20 wants to come out in advance, it must keep opening its gold fingers.

Anyway, now he has joined the Soviet Union, including his father, uncle, and even my mother is running around the Soviet Union. Many times, he will act alone when he goes out, and he can handle it even if he makes up some lies.

"For the new engine project, the compressor we obtained is axial flow type, which is the same as s-6 and s-8, but the structure is more complicated. In this design, the replacement unit structure of Pratt & Whitney in the United States is composed of compressors, combustion chambers, high-pressure turbines, drive compressors, low-pressure turbines, drive fans and exhaust systems, so as to facilitate later maintenance..." Xie Kai had a fart picture in his hand.

Wrought Fan-15 was still in a strict confidentiality state at the last moment of his original world.

Even some data is calculated by the outside world.

Anyway, that thing is equipped with the J-20. The turbofan-10 is used for the J-20, which will limit the J-20's supersonic cruise capability due to thrust. After all, this engine is based on the core engine technology of the CFM56 aircraft engine of Ge Company. The thrust is less than eight tons, and the thrust-to-weight ratio is only 7.5. Even the turbofan-10a, this is the product of the combination of the CFM56 core engine technology and the Al-31f core engine technology.

The maximum thrust exceeded 13 tons, and the thrust-to-weight ratio also reached 8.1.

Even the al-31 engine introduced from Russia has a thrust of only about eight tons.

Although the J-20 using the turbofan-10a can reach supersonic speed, it cannot achieve long-term speed cruise of Mach 1.5 or above.

Only the maximum thrust of the Turbofan-15 can reach 18 tons, which is more suitable for use in the J-20. It can not only be used for supersonic cruise, but also make the maximum range reach 6,500 kilometers. Without air refueling, the combat radius can exceed 2,200 kilometers, which is larger than the radius of ordinary bombers.

"The entire engine uses a three-stage fan, nine-stage rectifier, one-stage high-voltage, and one-stage low-voltage structure. It must adopt a transsonic fan design to ensure the maneuverability of low-altitude flight..." Xie Kai said while searching for the information in his mind.

"The technologies involved in the entire engine include air-cooled high-temperature blades, electronic beam welding integral fan rotors, titanium alloy precision casting intermediary receivers; extruded oil film bearings, brush seals, high-energy ignition nozzles, air-core afterburner fuel pumps, rectifier blades with variable curvature, convergence and diffusion outlets, high-pressure receiver processing and whole machine unit design, etc. Many things are being studied in China. How is the progress? You are all leaders in the aero engine industry and know these better than me."

When Xie Kai talked about these techniques, Jiang Chenyang's face became increasingly ugly.

After five years, it seems impossible to get a prototype.

All of these technologies are the top cutting-edge technologies in the world, and even a lot of things are blank in China and have just begun to study them.

Fortunately, he didn't say too much before, as long as the supporting technology or something is kept up.

"Will the risk be too great with such many cutting-edge technologies?" Sun Hong asked with a frown.

He still hopes to be safe.

Xie Kai just got some structural designs. Regardless of the domestic reality, there is no possibility of launching such a project to solve.

"The bass engine has introduced a complete set of production technologies, and it has not been domestically produced until now." Liao Dongfeng also raised questions.

Huo Haiyuan was also shocked when he listened.

404's plan for the fighter jet project this time is obviously quite large.

He originally thought that Xie Kai and Zheng Yucheng told them that the Super Seven Project were to practice, build a team, and train newcomers to urge them to complete it as soon as possible. Even the stealth fighter project that Xie Kai mentioned was just a cake for them.

As a fighter designer, I don’t know much about the engine, but I have to understand it.

This is serious.

404 The overall focus of the next ten years will even be on this.

An investment of more than 10 billion yuan is definitely not a joke.

Having confirmed that 404 was going to really do this project, Huo Haiyuan even regretted coming with him.

Too much pressure!

"I think you all know their problems. Dongfeng Power Plant is our 404 subordinate, with independent projects, independent management, and self-raised scientific research funds. Everyone should be clear about this." Zheng Yucheng said, "This is a supporting project for a new major project for us. Our minimum project is 13 years. If it really doesn't work, it's only twenty years, thirty years or even fifty years!"

The old man said it with a ruthless spirit.

If you don't make this, you won't give up.

"The task is very arduous, and it is not without hope of completion. We will cooperate with the whole country and work hard together. I don't require much time to create a prototype, but I just hope it can be done in the shortest time we can do it! Funds will not be short, and we will try our best to improve various supporting facilities and find partners..." Zheng Yucheng's words made everyone feel relaxed.

Then I found that the pressure was even greater.

Investors do not consider costs at all and consequences.

This is no different from gambling.

Xie Kai also looked at Zheng Yucheng with some surprise. When did the old guy become so crazy?

I proposed this myself because I know the structure and understand a lot of theories. I just use my gold finger to speed up the process and reduce R&D costs.

Zheng Yucheng doesn’t even understand a lot of things, so where does he get the confidence?

Do you really believe that you have obtained a complete set of design drawings?

"So, this project has to start building a team today. I think there should be no problem with Mr. Jiang as the person in charge." Xie Kai looked at Jiang Chenyang and said calmly.
Chapter completed!
