Chapter 1143

Whether it is surveying and mapping imitation, or self-development, and so on, as long as there is, the country will no longer waste funds. Moreover, the technology of big push is complex and not so easy to obtain.

In this case, the research just found a blank breakthrough.

Large and key units in China are engaged in large-scale promotion, but no one is engaged in middle promotion, and middle promotion happens to have an impact object.

For example, the j-14 fighters produced domestically have been controlled by others in export because they do not have a suitable engine. If they have an engine, they can be exported to more countries without looking at the faces of the eagle people!

This was a breakthrough they aimed at, and Qin Guan thought more.

Once zhongtui is developed, it will not only provide support for the j-14.

The J-8 can also be used. Now Gu Zong has been equipping their J-8 with rb199. Do you want to have more advanced combat effectiveness?

The domestic air force certainly doesn't like this kind of goods, but there will be big financiers abroad to buy it.

With this kind of turbofan engine, the range is longer and the acceleration is better. Maybe the performance can be effectively improved. At the same time, it can also reserve power for the future.

After what?

Of course, it is the future UAV. In future generations, UAV is popular. The power required by UAV is precisely the category of middle push. It can be said that it is of great significance to develop a middle push.

Let's say now, not to mention anything else.

"Although we intend to refer to the mainstream engines f404 and rb199 at that time, we do not intend to find a copy reference like other engines. We need to completely self-study, such as compressor stage 7. We need to start from the first stage, increase level by level, and study level by level to truly master the technology."

Kang Lao's idea was greatly admired by everyone. Qin Guan also gave a thumbs up. Yes, if he did so, he could really master the technology. Unlike us now, it's hard to modify.

The turbofan-12 in history is indeed such a project. It is the only compressor that has been studied step by step.

For another example, its short burst diffuser ultra compact annular combustor is inspired by rb199, which is nearly half shorter than that of f404. The three-stage fan design is closer to 404, but the parameters are completely different.

In short, the overall design parameters of the final WS12 are reasonable. There are three stages of small aspect ratio non shouldered fan, seven stages of compressor and one stage of high and low pressure turbine. The engine culvert ratio is about 0.5, the length is about 4000 mm, the fan inlet is 880 mm, the maximum diameter of the engine is about 1 meter, the total boost ratio is 23, the front temperature of the turbine is 1600K, the maximum military thrust is 5300 kg, the maximum thrust is 8700 kg, and the engine weighs 1080 kg.

It can be said that this engine has finally reached an order of magnitude of M88. Unfortunately, this engine finally got off the horse because there was no installation object. Instead, it went to build a mapping imitation rd93 engine. All the technical indicators have regressed, which makes people sigh.

Historically, this project was started in the late 1980s, but now, due to the promotion of Qin Guan, domestic aviation scientific research has made great progress. Even if the state's funds are limited, its vision has been broadened and it is decided to move forward along the right path.

"By the way, Mr. Kang, you just said that the current 6624 institutes have also begun to adopt the contract system and contract system, haven't you?" Qin Guan asked.

Qin Guan suddenly asked such a question. Kang laodun was very strange. He didn't know what he wanted to say. He still nodded: "yes, that's it."

"In that case, can our northern industrial company also participate?" Qin Guan said: "how about we inject funds into this project and get some shares at the same time?"

Hearing his words, Kang and others were overjoyed.

The biggest defect of their pre research project is the lack of funds, which may lead to the end of the project at any time. After all, the country is short of funds, and the research and development of engines is the most expensive.

The northern industrial company has already made a lot of money in a series of foreign arms sales. If they provide funds, it can certainly make the project go on!

"Of course, that's great," said Kang. "Unfortunately, our research institute is state-owned, otherwise you can buy our company."

If you can become a subsidiary of the northern industrial company, you will not have to worry about capital anymore. If you rely on the northern industrial company, you will not be afraid of anything.

Qin Guan shook his head: "no, we'd better inject funds. We promise to inject 100 million funds and occupy 20% of the shares of this project within ten years. How about it?"

100 million, which is almost enough for all the R & D expenses. Hearing Qin Guan's words, old Kang was happy: "of course, that's great!"

It costs a lot of money to study the engine. It takes a lot of money to do an experiment. In the past, it was reported to the superior, approved and approved before the experiment.

Now that you have money, you can spend it vigorously. Ten million a year, do whatever experiments you want.

"However, I have one request." Qin Guan said, "our indicators should be improved. We should aim at the engine with a thrust weight ratio of 10."

Hearing this, everyone was stunned, wouldn't they? Who can achieve this target?

Qin Guan certainly knows that this goal is ahead of schedule. According to the plan of 6624 Institute, the turbofan-12, which is similar to f404 engine, is already very rebellious.

But if so, what are the advantages of your own system?

According to Qin Guan's plan, in the 1990s, domestic advanced fourth generation fighters will appear. Such fighters should catch up with the level of the West.

It's time to start pre research.

On the third generation aircraft, our side has caught up. Now, although there are still problems with the engine, with the efforts of 4430 factory, the big promotion of the third generation can certainly be achieved. 6624 Institute, as a Turbine Research Institute, should play the role of pre research. The third generation engine already exists. Why do you still pre research? The fourth generation engine needs to be pre researched.

As for the middle push they are going to do, they have already made a plan and handed it over to factory 4460. They will do it again. It is repetitive. Anyway, it is pre research. Let's set the index higher now.

"If you think there are difficulties, if you can't do it in ten years, then you can't do it in fifteen years. In short, this index can't be changed. How about the push weight ratio of 10? You think it's exaggeration?" Qin Guan looked at the faces of the people and knew that they still wouldn't believe it.

"But we can't wait. We have to aim at the ATF plan of the eagle people!"
