Rebirth of Military Workers

Chapter 874

“It is true. To get the material, you need a stronger tool, otherwise it can’t be processed…” Wang Guilin also sighed.

404 has a dedicated tooling and tool production workshop.

Their basic material research is based on the technology of this workshop, but now this workshop only bears the burden of sample production, material research, etc., which belong to the specialized material research department.

Now the technical demonstration work of the Turbofan-10, which is the preparatory work before the theoretical design, will be fully and directly presented in front of everyone.

“Under the current situation, only relying on our family’s ability, even if it is designed, can not transform the design into technology and ultimately into a product.” Jiang Chenyang seems not afraid to offend Xie Kai at all. “National linkage, all units work together. None of them can be completed in a short time. This is similar to many of the projects we dismantled before. The performance indicators are very high. Some designs have been completed, but it is impossible to move from drawings to products.”

In a word, the performance index of Turbofan-10 is too high, and it is not suitable for it now.

Liao Dongfeng looked at Wang Guilin and Xie Kai worriedly.

Once they are unhappy, the life of Dongfeng Power Plant will be difficult in the future.

They are no longer the original state-appropriated units. The state-appropriation has no funds at all when there is no production order.

The main production in the past two years has been to produce matching engines for the 132 plant.

The output is now much less. The production of engines such as the J-7 and J-8 can be produced by any aviation power plant in the country, and the competition is very fierce.

Everyone is basically in a state of starvation.

“Then do it slowly.” Xie Kai is still firm in his opinion. “I didn’t mean to cooperate with several units before? Whether it is Dongfang Turbine Factory or 430 Factory, cooperation can be done. However, we need more than just cooperation. It is them, it should be all the units involved in aviation engines in the country.”

“Such a big deal?” Liao Dongfeng looked at Wang Guilin in disbelief.

“I said before, for the aviation engine, we don’t hesitate to pay.” Xie Kai said calmly, now this is not at all costs. “Director Wang and the management committee felt that it was only the three units that were combined, and the technical experience was still not enough. It would be better to unite the public relations nationwide.”

Xie Kai directly pushed the matter to Wang Guilin, they were more convincing than themselves.

Wang Guilin didn’t explain anything. He directly introduced the situation and said that Minister Shen Hong, who is over 80 years old, would be invited to help preside over the collaborative research and development of all units across the country.

It’s really big.

It is far beyond the imagination of Liao Dongfeng and others.

“We can learn from the bass engine technology of the West Air Development 430 Factory, plus the F-14 TF30-P-412 afterburner turbofan engine from Pratt & Whitney, and Pratt & Whitney JT3D and other engine technologies. , It’s much easier.” Jiang Chenyang said, “In terms of design, under such circumstances, the problem is not too big. The only thing is the processing and manufacturing capabilities.”

“Those problems will be solved. We will design them first.” Wang Guilin saw Xie Kai silently and proactively said, “This time I am here to communicate with them about cooperation with other units. After all, it is based on this project. To build a powerful core machine, it is better to build a slightly simpler core machine for technical verification, and then fully invest in the turbofan-10 after the technology is mature, or directly accelerate the progress of the turbofan-10.”

“Turbofan-6, are you still doing it?” Sun Hong asked worriedly.

The improved model of turbofan-6, although the thrust-to-weight ratio has reached an unprecedented height in the field of domestic engines, there is no applicable object.

The strength of Dongfeng Power Plant is good, and it is too reluctant to engage in three or four engine projects at the same time.

This is also a problem that has always plagued everyone.

“If you start with a lower technical difficulty, you can use some of the turbofan-6 and turbofan-8 technologies to build a core machine; if you do it separately, the improvement work of the turbofan-6 will have to continue, but it cannot be like Now such continuous large-scale investment.”

“The turbofan-6 is not without applicable objects…” Sun Hong said quietly.

Xie Kai came interested, “Transport plane?”

Turbofan-6 is the first military engine with a thrust-to-weight ratio of 6 studied in China.

Later, there were three models of Turbofan-6. Among them, the basic turbofan-6 and the turbofan-6G improved from the turbofan-6 were used for high-altitude and high-speed fighters like the J-9. ; The turbofan-6A is used for transport aircraft.

At present, the domestic transport aircraft is not used. It is used for transporting ten. The turbofan-8 seems to have lost its effect; used for transporting -8? That thing is a turboprop engine…

“No, fighter. JH-7!” Sun Hong said.(Read more @ wuxiax.com)

When these words came out, not only Xie Kai was embarrassed, but even Wang Guilin and others felt that this matter was not feasible.

The JH VII now uses a bass engine imported from the UK.

The localization of the Bass engine has never achieved a breakthrough, and the key process is solved by obtaining the powder metallurgy integral casting technology and forging processing capabilities from the 404 side.

The introduction of bass engines by the country cost hundreds of millions of pounds!

“The performance parameters of the turbofan-6 are much higher than those of the bass, which can not only increase the bomb load of the JH-7, but also help increase the flight speed.” Sun Hong said, “I improved the design at the beginning, in fact, We have also thought about it, but the supporting engine of the JH-7 is the bass…”

“Now the localization of bass is similar to our turbofan-6 improved version.” Wang Guilin said.

Xie Kai suddenly felt that there seemed to be too many domestic engine projects.

Turbofan-6, turbofan-8, turbofan-9, and turbojet-8 and other projects.

There are many types, but none of them are powerful.

It is no wonder that Wang Guilin hopes to integrate the relevant units of the national aero-engine system to produce a whole core machine.

Now these engines, except for the turbofan-6, which is independently designed and developed, the turbofan-8 is for Yunshi, imitating the Pratt & Whitney JT3D; the turbofan-9 is the imported bass engine, which is used for the JH-7; The turbofan-11 has also been activated. It is an imitation of the Ukrainian AL-222-25 turbofan engine, which is for the K-8…

Many models are messy.

However, it has not formed a stable system like the foreign aviation engine R&D and manufacturing system.

It’s time to change this situation.

“If the JH-7 is used, it will squeeze out the living space of the bass, and the country’s hundreds of millions of pounds of investment will be wasted.” Xie Kai is not unconcerned about this matter, but it matters too much.

“So we hope it can be used on Super-7A or Super-7B.” Sun Hong gritted his teeth and said.

They do not want to give up the Turbofan-6 results that have reached this level.

“Can you communicate with the design team over there? Can it be used?” Xie Kai didn’t care.

He has purchased 200 RD-33 engines, and he is not worried at all.

“Yes, but Mr. Huo is worried that the RD-33 engine in the warehouse will be wasted…” Sun Hong looked at Xie Kai and didn’t say anything.

The RD-33 engine was bought by Xie Jianguo. Anyone who knows the inside information knows that it was Xie Jianguo who gave Xie Kai the back of the pot.

Although Xie Kai doesn’t have any substance, it has a lot of power in his hands, and what he says has a great influence on the entire 404 system.

With the turbofan-6, the RD-33 engine can only be placed in the warehouse to rust.

Lao Maozi is short of money, more than 200 million US dollars, a total of 200 engines, and now all have been delivered.

Otherwise, Super-7A will not continue to be produced in small batches.

“What’s the waste? The performance of the turbofan-6 is better than that of the RD-33 in some aspects? The imported Soviet engine is used for the export version, and the super-7A improved from our domestic engine is our own. Use it.” Xie Kai said with a smile. “When the United States and the Soviet Union export weapons and equipment, don’t they have to make an export version? We do the same.”

“Two hundred Super-7A, can you sell it?” Wang Guilin frowned and asked Xie Kai.

Is this bull blowing a bit louder?

The Super-7B was originally prepared to be equipped with the RD-33 engine.

“I don’t know, it should be possible.” Xie Kai said, “The turbofan-6 can also be used for the test flight of Super-7B.”

Xie Kai could see away.

The power system can be replaced, anyway, the aerospace industry design ability needs to accumulate experience and technology.

Super Seven, from the very beginning, the positioning given by Xie Kai is to train their own design team.

What is really going to be a super fighter like the J-20.

Wang Guilin looked at Xie Kai, wondering if he was forced to say the truth or was forced to say so.

“Then I will tell them at the 430 factory, do we agree to jointly build engines?” Liao Dongfeng asked tentatively.

Xie Kai didn’t object, and Wang Guilin also expressed support, so this is naturally the case.

After coming down, Wang Guilin asked Xie Kai on the way back to 132, “Is this your true thoughts?”

“Otherwise?” Xie Kai also knew what Wang Guilin was referring to. “I was afraid that I would have no heart when I bought Lao Maozi’s RD-33 engine. Who would have thought that our aero engine would make such a rapid breakthrough in the past two years? ”

Xie Kai can’t say that he didn’t understand the situation of domestic aero engines at all when his head was hot.

The Super Seven project was originally improved on the basis of the J-9.

The performance indicators of the turbofan-6 for the J-9 have been reached, and even the whole machine has been tested for hundreds of hours.

Empiricism kills people. Before that, he always thought that domestic aero engines were too rubbish and unusable.

Given the opportunity, coupled with the fact that the Americans will be involved when the Soviet Union is about to disintegrate, Russia, which has inherited most of the Soviet heritage, is asking for high prices during the negotiation of technology introduction, etc…

In the end, he made a decision to purchase 200 RD-33 engines.

“Anyway, the RD-33 engine must not be smashed in your hands.”

“What about the customer?”

“Aren’t there still fat sheep waiting for us? Didn’t they dislike the J-7?” Xie Kai couldn’t help it. “I think they should be very interested in fighters like Super-7B.”
