Chapter 592

“There is no budget, but as long as there is a breakthrough, we need as much as we want. We will find a way if we don’t have one!” Zheng Yucheng also knows that Xie Kai was aggrieved by buying the engine.

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

As for the aero engine, they said at the beginning that it would cost money.

If it weren’t for the Super Seven as soon as possible and sell it, it would not spend more than $200 million to purchase 200 engines that are not too advanced.

Zheng Yucheng knew clearly.

There was a sound of inhaling cold air below.

“In addition, the previous two projects will continue to be tested. At the same time, I hope everyone will integrate the core technical strength. We are going to establish a new military engine project. The technical requirement for the thrust-to-weight ratio will be 10. The minimum is not less than 9.5, the minimum thrust is 110 kN, and the afterburner thrust is more than 180 kN.” Zheng Yucheng announced the new project, causing the entire conference room to fall into deathly silence.

Then there was an uproar.

“This is impossible!”

“Our foundation is too bad.”

“Even if it is designed, we will not be able to produce it, and the basic technology field can’t keep up.”

“It’s totally rash, it’s impossible to complete.”

Everyone felt that Zheng Yu was crazy.

“Director Zheng, we all understand your feelings. But the current reality is also before everyone’s eyes. Unrealistically proposing such technical indicators is completely inconsistent with our national conditions…” Sun Hong opened with difficulty mouth. “At the beginning, the J-9 project proposed too high technical indicators, and all aspects were unable to keep up. It eventually consumed a large amount of national funds and was dismounted. At the same time, the J-8 has now been installed with troops and become the main force of the new generation of the Air Force …”

Tactfully reminded that this technical index proposed by Zheng Yucheng is too aggressive.

This is completely the work style of “catching up with the English Premier League” in the 1960s, and it is totally unrealistic.

Sun Hong’s words are quite tactful.

“At present, our country is not suitable for such an engine at all, even if it is a large press, there is no way. The materials can not keep up, the manufacturing process can not keep up. The powder metallurgy industry has not obtained much in China. Breakthrough…” Jiang Chenyang also pointed out with a serious expression, “Instead of wasting funds, it is better to lay a solid foundation for these funds and cultivate a team of scientific research talents.”

“In the process of research and development, we can train the team more and consolidate the foundation. If we only toss on the foundation, what can we toss?” Zheng Yucheng asked rhetorically. “The 617 factory has always been very conservative in developing tanks step by step… In the end, they sold thousands of tanks, and the profit was not as good as we sold hundreds of them.”

The more advanced things are, the better prices can be sold, and the market is better.

“You may think that the technical indicators of this engine are very high. Before, when we discussed, we also felt that it was completely impossible. However, when we went to the Soviet Union, we got a copy of their most advanced aviation design… Xie Kai said.

Everyone was stunned.

Zheng Yucheng is no stranger to it.

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

I wouldn’t say it anyway.

Others don’t have the knowledge of Zheng Yucheng, and Xie Kai is just a yellow-haired kid, so it’s not reliable at all.

“Just the structural design is useless at all.” Sun Hong smiled bitterly.

The child of Xie Kai, Zheng Yucheng and others are too spoiled, they don’t know the sky is high and the earth is thick.

“If there are technical requirements and instructions for each part, and even some new materials as support?” Xie Kai asked.

“If the situation is really like this, the supporting equipment can keep up, the materials are no problem, I dare to make a military order, and the prototype will be able to ignite within five years!” Jiang Chenyang stood up and patted his chest to make sure.(Read more @ wuxiax.com)

With assembly design drawings, detailed technical requirements, and even supply of raw materials, prototypes are not a problem.

After all, the prototype is only used to verify the technology, and the service life, etc., can be ignored. The ignition success, test thrust and other data are 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 conditions of this engine first.”

Xie Kai was also forced to have no choice.

If the J-20 wants to come out early, it must constantly open cheats.

Anyway, he is now on the line with the Soviet Union, with his father, his brother-in-law, and even his wife running into the Soviet Union. He often goes out by himself alone, and he can deal with it by making up some lies.

“As for the new engine project, the compressor on the drawing we obtained is of the axial flow type, which is the same type as WS-6 and WS-8, but the structure is more complicated. In this design, the United States Pratt & Whitney is used. The company’s replaceable unit structure is composed of compressor, combustion chamber, high-pressure turbine that drives the compressor, low-pressure turbine that drives the fan, and exhaust system, which is convenient for later maintenance…” Xie Kai has a fart in his hand. Figure.

Turbofan-15 was still in strict secrecy in the last moments of his original world.

Even some data are extrapolated from outsiders.

Anyway, that thing is for 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 problems. After all, this engine is based on the core technology of GE’s CFM56 aero engine, with a thrust of less than eight tons and a thrust-to-weight ratio of only 7.5; even the turbofan-10A is the core of CFM56 core technology and AL-31F. The product of a combination of machine technology.

The maximum thrust exceeds 13 tons, and the thrust-to-weight ratio also reaches 8.1.

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

Although the J-20 using turbofan-10A can reach supersonic speed, it cannot achieve long-term cruises above Mach 1.5.

Only the turbofan-15 which can reach the maximum thrust of 18 tons is more suitable for the J-20. It can not only do supersonic cruising, but also allow the maximum range to reach 6,500 kilometers. In the absence of air refueling, the combat radius It can exceed 2,200 kilometers, which is larger than the average bomber radius.

“The whole engine uses a three-stage fan, nine-stage rectification, one-stage high-voltage, and one-stage low-voltage altogether twelve stages, which is a 3+9+1+1 structure. The transonic fan design must be adopted to ensure the maneuverability of low-altitude flight… …” Xie Kai said, searching for the information in his mind.

“The technologies involved in the entire engine include air-cooled high-temperature blades, electron beam welding integral fan rotors, titanium alloy precision-cast intermediate casings; squeeze oil film bearings, brush seals, high-energy ignition nozzles, and air-core afterburner fuel pumps. Rectifier blades with variable camber, random convergence and diffusion, high-pressure casing treatment and unit body design, etc. Many things are being researched in China. How is the progress? Everyone is a leader in the aero-engine industry, and I know these things better than me. ”

When Xie Kai talked about these techniques, Jiang Chenyang’s face became more and more ugly.

In five years, it seemed impossible to get a prototype.

These technologies are all the top cutting-edge technologies in the entire world, and even many things are blank in China, and they have just begun to study.

Fortunately, he didn’t say too much before, provided that the supporting technology keeps up.

“Will the use of so many cutting-edge technologies be too risky?” Sun Hong frowned and asked.

He still hopes to be safe.

Xie Kai only got some structural designs. Regardless of the domestic reality, it is impossible to solve a project like this.

“The bass engine has introduced a full set of production technology, but it has not been localized until now.” Liao Dongfeng also questioned.

Huo Haiyuan was also terrified as he listened.

The 404’s plan on the fighter project is obviously not small.

He originally thought that Xie Kai and Zheng Yucheng said that the Super Seven Project was for them to practice their hands, build a team, and train newcomers to urge them to complete it as soon as possible. Even the stealth fighter project Xie Kai talked about is just a pie for them.

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

This is true.

The overall focus of 404 in the next ten years is even on this.

An investment of more than tens of billions is definitely not a joke.

After confirming that 404 would really work on this project, Huo Haiyuan even regretted coming over with him.

too much stress!

“I think you all know about their problems. Dongfeng Power Plant, which belongs to our 404 subordinate, has independent projects, independent operations, and self-raised research funding. This point should be clear to everyone.” Zheng Yucheng said, “This is a new type of major for us. The project is supporting, and that project, we have the least estimated time of 13 years, it is not good, only 20 years, 30 years or even 50 years!”

The old man’s words, with a fierce force.

If you don’t make this, you will never give up.

“The task is very arduous, and it is not an unfinished hope. We will cooperate with the national system and we will work together. I don’t ask for much time to build a prototype. I just hope that it can be done in the shortest time we can do! Funding! There will be no shortage. We will try our best to improve various supporting facilities and find partners…” Zheng Yucheng’s words made everyone feel relieved.

Then I found out that the pressure was even greater.

The investor completely ignores the cost and does not consider the consequences.

This is no different from gambling.

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

I came up with this because I know the structure and a lot of theories. I use my golden finger to speed up the process and reduce R&D costs.

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

Do you really believe that you got a full set of design drawings?

“So, for this project, we have to form a team today. I think there should be no problem with President Jiang being the person in charge.” Xie Kai looked at Jiang Chenyang and said calmly.

Upon hearing this, Jiang Chenyang’s face was ashen ashes.
