"Yes, indeed. To get out the material, you need a tool with higher strength, otherwise it can't ......be processed," Wang Guilin also sighed.

404 has a special tooling tool production workshop.

Their basic material research is based on the technology of this workshop, but now this workshop is only responsible for sample production, material research, etc., and belongs to a special material research department.

Now the technical demonstration work of turbofan-10, that is, the preparatory work before the theoretical design, all kinds of problems will be comprehensively and directly presented in front of everyone.

"In the current situation, we alone rely on our ability, even if we design it, we can't turn the design into technology and finally into a product. Jiang Chenyang didn't seem to be afraid of offending Xie Kai at all, "The national linkage and the joint efforts of all units are not something that can be completed in a short time." This is similar to many of the projects we have done before, the performance indicators are very high, and some of the designs have been completed, but they can't move from drawings to products. ”

In a word, the performance indicators of the turbofan-10 are too high, and it is not suitable for it now.

Liao Dongfeng looked at Wang Guilin and Xie Kai worriedly.

Once they are not happy, the life of Dongfeng Power Plant will not be easy in the future.

They are no longer the units that belonged to the state appropriation, and the state appropriation has no funds at all in the absence of production orders.

The main production in these two years was for the production of engines for fighter jets at Plant 132.

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

Usually, everyone basically stays in a state of starvation.

"Then take your time. Xie Kai still firmly held his opinion, "Didn't you say that you would cooperate with several units before? Whether it is Dongfang Steam Turbine Factory, or 430 Factory, etc., cooperation can be done." However, we need cooperation not only with them, but with all units involved in aero engines in the country. ”

"It's so big?" Liao Dongfeng looked at Wang Guilin with some disbelief.

"As I said before, for the sake of aero engines, we will do whatever it takes. Xie Kai said calmly, and now this is not the level of sparing costs. Director Wang and the management committee felt that it was only the union of the three units, and the technical experience was still not enough, so it was better to unite the whole country for public relations. ”

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

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

It's really big.

far more than Liao Dongfeng and others imagined.

"We can learn from the bass engine technology of the 430 factory of Xihangfa, plus the F-14 TF30-P-412 afterburner turbofan engine from Pratt & Whitney, as well as Pratt & Whitney's JT3D and other engine technologies, so that it is much easier. Jiang Chenyang said, "In terms of design, in such a situation, the problem is not too big. The only thing is the processing and manufacturing capacity. ”

"Those problems will be solved, and they will be designed first. Seeing that Xie Kai was silent, Wang Guilin took the initiative to say, "I came here this time to communicate with them about the issue of cooperation with other units." Whether to build a strong core machine based on this project, or to make a slightly simpler technical verification of the core machine, 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?" asked Sun Hong worriedly.

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

Dongfeng Power Plant has a good strength, but it is too reluctant to engage in three or four engine projects at the same time.

This is also a question that has been plaguing everyone for a long time.

"If we start with a lower technical difficulty, we will use the fusion of some technologies of turbofan-6 and turbofan-8 to build a core machine; if we do it alone, the improvement of turbofan-6 must continue, but we cannot continue to invest on a large scale as we are now. ”

"It's not that the turbofan-6 is not unapplicable...... Sun Hong said quietly.

Xie Kai became interested, "Transport plane?"

The turbofan-6 is the first military engine with a thrust-to-weight ratio of 6 in domestic research.

Later, there were three models of turbofan-6, among them, the turbofan-6 as the basic model, and the turbofan-6G improved from the turbofan-6, were used for high-altitude and high-speed fighters such as the J-9, and the turbofan-6A was used for transport aircraft.

At present, there is no object for the use of domestic transport aircraft, and the turbofan-8 seems to have lost its role when it is used for the Y-8......

"No, fighter. J-7!" Sun Hong said.

As soon as these words came out, not only Xie Kai was embarrassed, but even Wang Guilin felt that this matter was not feasible.

The J-7 now uses a bass engine imported from the UK.

There has been no breakthrough in the localization of bass engines, and the overall casting technology and forging processing capacity of powder metallurgy are obtained from 404 to solve the key process.

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 J-7, but also help to increase the flight speed. Sun Hong introduced, "At the beginning, we also thought about improving the design, but the supporting engine of the J-7 is the bass ......."

"Now the localization of bass is similar to that of 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 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 and come out with a whole core machine.

Now these engines, except for the turbofan-6, which is independently designed and developed, the turbofan-8 is for the Yun-10, which is an imitation of the Pratt & Whitney JT3D; the turbofan-9 is the imported bass engine, which is for the J-7; the turbofan-11 is also started, and that thing is an imitation of the Ukrainian AL-222-25 turbofan engine, which is for the K-8......

There are many models and they are messy.

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

It's time to change that.

"If it is used on the J-7, it will squeeze the living space of the bass, and the country's investment of hundreds of millions of pounds will be wasted. "Xie Kai is not without ideas about this, but it has too much to do with it.

"So we hope we can use it on the Super 7A or Super 7B. Sun Hong gritted his teeth and said.

They did not want to abandon the achievements of the turbofan-6, which had already reached such an extent.

"Have you communicated with the design team over there, can you use it?" Xie Kai didn't care.

The RD-33 engine was procured 200 units, and he was not at all worried.

"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 back by Xie Jianguo, and those who know the inside story know that it was Xie Jianguo who gave Xie Kai the blame.

Although Xie Kai does not have any substance now, he 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 could only be left rusty in the warehouse.

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

Otherwise, the Super-7A would not have been produced in small batches continuously.

"What's the waste? The performance of the turbofan-6 is better than the RD-33 in some respects, right? The imported Soviet engine is used for export version, and the super-7A improved from our domestic engine is used by itself. Xie Kai said with a smile. "Doesn't the United States and the Soviet Union have to make an export version of their weapons and equipment? ”

"Two hundred Super -7A, can you sell them?" Wang Guilin asked Xie Kai with a frown.

Isn't this bull blowing a little too big?

The Super-7B was also intended to be equipped with RD-33 engines.

"I don't know, I guess I can. Xie Kai said, "The turbofan-6 can also be used for the test flight of the super-7B." ”

Xie Kai can see it.

The power system or something can be replaced, anyway, the design ability of the aviation industry needs to accumulate experience and technology.

Super Seven, from the very beginning, Xie Kai's positioning was to practice for their own design team.

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

Wang Guilin looked at Xie Kai, not knowing if he was telling the truth or being forced to say this helplessly.

"Then I'll tell them at Factory 430 that we agree to jointly build an engine?" asked Liao Dongfeng tentatively.

Xie Kai did not object, and Wang Guilin also expressed his support, so this matter is naturally like this.

After coming down, Wang Guilin asked Xie Kai on the way back to 132, "What do you really think about this matter?"

"Then what's not?" Xie Kai also knew what Wang Guilin was referring to, "When I bought Lao Maozi's RD-33 engine, I was afraid that I would not have a heart when it was designed." Who would have thought that in the past two years our aero engines would make such a rapid breakthrough?"

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

The Super 7 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 test run of the whole machine has taken hundreds of hours.

Empiricism kills people, and he has always thought that domestic aero engines are too rubbish to use.

With the opportunity, coupled with the fact that the Americans knew that the Americans would make trouble when the Soviet Union was about to collapse, Russia, which inherited most of the Soviet legacy, demanded sky-high prices in the process of technology import negotiations......

Ultimately, it led him to make the 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? Aren't they disgusted with the J-7?" Xie Kai also had no choice. "I think they should be very interested in a fighter like the Super 7B. ”
