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

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

Aero engines, they said at the beginning, spend money to smash.

If it weren't for the fact that it was to get the Super Seven as soon as possible and sell it, it would not have cost more than $200 million to purchase 200 engines that were not too advanced.

Zheng Yucheng knows it clearly.

There was a gasp below.

"In addition, the previous two projects, will continue to test, at the same time, I hope you integrate the core of the backbone of the technical force, we want to set up a new military engine project, the thrust-to-weight ratio of the technical requirements, will be 10, the minimum is not less than 9.5, the minimum thrust of 110 kN, afterburner thrust of more than 180 kN. Zheng Yucheng announced a new project, which plunged the entire conference room into a deathly silence.

An uproar ensued.

"It can't be!"

"We're too bad. ”

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

"It's just a rush, and there's no way to do it. ”

......

Everyone thinks Zheng Yucheng is crazy.

"Director Zheng, we all know your feelings. However, the current reality is also in front of everyone, and unrealistically putting forward such technical indicators is completely inconsistent with our national conditions......" Sun Hong opened his mouth with difficulty. "At the beginning, the J-9 project put forward too high technical indicators, and all aspects could not keep up, and finally consumed a lot of national funds and was dismounted. At the same time, the J-8 has now been installed in the army and has become the main force of the new generation of the Air Force......"

Euphemistically, this kind of technical indicator proposed by Zheng Yucheng is too aggressive.

This is completely the kind of work style that China put forward in the 60s to "catch up with Britain and surpass the United States", and it is completely unrealistic.

Sun Hong's words have been said quite tactfully.

"At present, we are not suitable for such an engine in China, even if a large press is made, there is no way. The materials can't keep up, and the manufacturing process can't keep up. Powder metallurgy, there has not been much breakthrough in China......" Jiang Chenyang also pointed out with a serious expression, "Instead of wasting funds, it is better to lay a solid foundation and cultivate a team of scientific research talents." ”

"In the process of research and development, we can train the team more and lay a solid foundation. If you only toss on the foundation, what can you toss out?" Zheng Yucheng asked rhetorically. "Plant 617 has always been very conservative in developing tanks step by step...... In the end, they sell a few thousand tanks, and the profit is not as good as ours selling a few hundred. ”

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

"You may think that the technical specifications of this engine are very high. In the past, when we discussed it, it was also completely impossible. However, when we went to the Soviet Union, we got a copy of their most advanced aircraft development blueprint design...... "Xie Kai said.

Everyone was stunned.

Zheng Yucheng is no longer surprised.

Although he doesn't know where Xie Kai got the drawings, and although the possibility of getting the drawings from the Soviet Union is not great, Zheng Yucheng will definitely not believe that Xie Kai can draw this thing himself.

Anyway, I won't say if I ask.

Others don't have Zheng Yucheng's cognition, Xie Kai is just a yellow-haired boy, and he is not reliable at all.

"It's just a structural design, it's useless. Sun Hong smiled bitterly.

Xie Kai, this kid, Zheng Yucheng and others are too spoiled, and they don't know that the sky is high and the earth is thick.

"What 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 facilities can keep up, there is no problem with the materials, I dare to make a military order, within five years, the prototype can be ignited!" Jiang Chenyang stood up and patted his chest to reassure.

With assembly design drawings, detailed technical requirements, and even a supply of raw materials, the prototype is not a problem.

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

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

Xie Kai was also forced to have no choice.

If the J-20 wants to come out in advance, it must constantly open the golden finger.

Anyway, now that he is on the line with the Soviet Union, he has his father and uncle, and even his mother is constantly running into the Soviet Union, and he himself often goes out alone and can deal with it by making up some lies.

"Regarding the new engine project, the drawings we got show that the compressor is axial flow, which is the same type as the S-6 and S-8, but the structure is more complicated. In this design, the replaceable unit structure of Pratt & Whitney is adopted, which is composed of a compressor, a combustion chamber, a high-pressure turbine that drives a compressor, a low-pressure turbine that drives a fan and an exhaust system, which is convenient for later maintenance...... "Xie Kai has a fart diagram in his hand.

The Turbofan-15 was kept under strict secrecy in the final moments of his original world.

Even some of the data is extrapolated from the outside world.

Anyway, that thing is for the J-20, and 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 engine 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, and even the turbofan-10A, which is a combination of CFM56 core engine technology and AL-31F core engine technology.

The maximum thrust is more than 13 tons, and the thrust-to-weight ratio is also 8.1.

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

The J-10 with turbofan-20A, although it can reach supersonic speeds, cannot cruise at speeds above Mach 1.5 for a long time.

Only the turbofan-15, which has a maximum thrust of 18 tons, is more suitable for the J-20, which can not only do supersonic cruise, but also make the maximum range reach 6500 kilometers, and in the absence of air refueling, the combat radius can exceed 2200 kilometers, which is larger than the radius of the general bomber.

"The whole engine adopts a three-stage fan, nine-stage rectification, one-stage high pressure, and one-stage low pressure, a total of 12 stages, that is, a 3+9+1+1 structure, and must be designed with a transonic fan to ensure the maneuver......ability of low-altitude flight," Xie Kai said, searching for the information in his mind.

"The technology involved in the whole engine includes air-cooled high-temperature blades, electron beam welding integral fan rotor, titanium alloy precision casting intermediary casing, extruded oil film bearing, brush seal, high-energy ignition nozzle, air-core afterburner fuel pump, rectifier blade with variable curvature, convergence and diffusion casual, high-pressure casing treatment and whole machine unit design, etc., many things, domestic research, how is the progress, you are all leaders in the aero engine industry, better than me. ”

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

Five years, to get a prototype, it seems impossible.

These technologies are all the top cutting-edge technologies in the world, and even a lot of things are blank in China, and they have just begun to be studied.

Fortunately, he didn't say too much before, provided that the supporting technology or something kept up.

"Wouldn't it be too risky to use such a number of cutting-edge technologies?" asked Sun Hong with a frown.

He still wants to be safe.

Xie Kai only got some structural designs, and regardless of the domestic reality, there is not much possibility to solve such a project.

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

Huo Haiyuan listened to it on the side, and he was also shocked.

404's plan on the fighter project this time is obviously not small.

He originally thought that Xie Kai and Zheng Yucheng said that the Super Seven Project would give them training, build a team, and train newcomers in order to urge them to complete it as soon as possible. Even the stealth fighter project that Xie Kai said was just a piece of cake for them.

The engine, as a fighter designer, does not understand in great detail, but has to understand.

It's real.

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

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

determined that 404 was going to really engage in this project, and Huo Haiyuan even regretted coming with him.

Too much pressure!

"Their problems, I think you know too. Dongfeng Power Plant, which belongs to our 404 subordinate, has independent projects, independent operation, and self-raised scientific research funds. This should be clear to everyone. Zheng Yucheng said, "This is a new type of major project for us, and that project, our minimum estimated time, has 13 years, but it really can't work, just 20 years, 30 years or even 50 years!"

The old man's words were tinged with ruthlessness.

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

"The task is daunting, and it is not without hope of completion. We will cooperate with the national system, everyone will work together, I don't ask for much time to get a prototype, I just hope to get it out in the shortest time we can do! Funds, there will be no shortage, all kinds of support, we will try our best to improve, looking for partners......" Zheng Yucheng's words made everyone feel relaxed.

Later, it turned out that the pressure was even greater.

The investor is completely reckless about the cost and does not consider the consequences.

It's no different from gambling.

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

I put this forward because I know the structure and understand a lot of theories, and I am completely using a golden finger to speed up the process and reduce the cost of research and development.

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

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

"So, for this project, we have to build a team today. I think there should be no problem for Mr. Jiang to be the person in charge. Xie Kai looked at Jiang Chenyang and said calmly.

As soon as he heard this, Jiang Chenyang's face instantly turned like ashes.
