Chapter 528

Domestic zhongtui is also available in later generations, which is turbofan-13

In that year, Han had completed the research and development of Xiaolong, and Xiong also agreed to provide rd-33 series engines (rd-93) to Han at a relatively low price. However, in view of international political reality, arms export policy and other restrictive factors, both Han and holy countries did not want Xiaolong to completely rely on rd-93 engines. Therefore, the aviation power manufacturers in China also began to take the initiative and actively seek alternatives.

In 2000, China introduced rd93 series engines and obtained a complete set of data. Combined with the achievements of zhongtui development, we began to develop the power, which is turbofan-13

This engine has three stages of fan and eight stages of high-pressure compressor. Compared with rd-33 engine, the fan is reduced by 1 stage and the high-pressure compressor is reduced by 1 stage. Structurally, it is closer to f404, but a 1-stage high-pressure compressor is added relatively.

The thrust with force is 86.37 kn, the fuel consumption rate is 2.02 kg / Dan hour, the thrust without force is 56.75 kn, and the fuel consumption rate is 0.73 kg / Dan hour. It should be said that in addition to the increase of afterburner thrust, the thrust without afterburner is significantly higher than rd93.

However, as for its reliability, it is not clear. According to the public information, holy nation did not decide to adopt turbofan-13, but still decided to use the original rd-93 engine.

The manufacturer has developed it, but the user is unwilling to use it. This can explain the problem.

Now, before the 1980s, the development of military aircraft engines in the Han Dynasty is almost zero. In this case, can we carry out the development of medium push?

If you want to develop it, you won't copy rd-93. It's f404.

In fact, in history, in the 1980s, the state of Han had obtained an f404 through the secret department. The push in the plan of the state of Han actually imitated the f404.

Now, if you want to sell super seven, you need to develop supporting engines. However, the supporting engines are difficult and expensive. If you start the project, you can't even invest in the benefits of the project. In this case, how can you raise funds for the Raptor project?

Qin Guan knew what major Yang thought. Now, this is a big problem.

How?

Qin Guan doesn't have a good way now.

Move the full set of data of f404, and then exchange some processing tools. In this way, give it to a manufacturer for research and development?

There are too few domestic engine research teams. Who should I give them to? The only thing that makes sense is the team of turbofan 6. However, first, Qin Guan is unwilling to use it, and second, people are unwilling to do it.

At the beginning, they didn't even want to carry the burden of imitating Spey. They just wanted to focus on turbofan 6.

If turbofan VI fails to settle down in the end, the project of turbofan 10 has to be handed over to their team.

This is a big problem!

By the way, which factory imitated turbofan-13 in the future? Qin Guan can't remember clearly.

After thinking for a long time, Qin Guan shook his head: "brother Yang, the problem of the engine is definitely our weakness, which requires years of technology accumulation and is the most lacking. Now, this problem can not be solved overnight. We have to move forward and try our best to find a solution to the problem, don't we?"

Facing Qin Guan's answer, Yang Shao nodded. He thought your boy was omnipotent. It seems that you can't do it now.

"Quack, little problem, it's not difficult for me."

At this time, the voice of the system suddenly sounded in Qin Guan's brain.

"Well, don't talk about small problems. If you let go of irrelevant processes, I'll see how you explain!" Qin Guan began to talk to the system in his brain.

Just a bra, Qin Guan could accept it. Qin Guan was afraid of this Lisa. She had such a strong learning ability and was unwilling to stay in her mind. What if she jumped out one day?

"Don't you want to hear what I can do?" the system said wrongfully.

"If I want to talk, I'll talk. If I don't want to talk, I'll go to bed," Qin Guan said.

"Well, as long as you upgrade and open my weapons production line cemetery, you can directly exchange the supporting production lines." the system said: "the production line of f404 engine was sealed in 2019. You can produce as long as you exchange the production line!"

Now, several graveyard systems have been unlocked, including weapon graveyard, weapon data graveyard, machine tool graveyard and currency graveyard, and the next one is the production line graveyard!

Qin Guan didn't take care of the system and withdrew.

Qin Guan has found that it is fate to upgrade this system. Where can he upgrade it casually.

I'm not going to die myself. Go and receive nuclear radiation?

Moreover, if the whole production line is exchanged, the spiritual point required is absolutely astronomical.

Besides, just having a production line is useless. Do you need so many industrial workers? Do you still need the cooperation of downstream manufacturers? This is the problem of the whole system.

It's like the eagle country of later generations. The president of the fountain decided to move all production back. A bicycle manufacturer also decided to produce independently in China. It was found that there were no downstream supporting manufacturers. If he produced it himself, the cost would be terrible.

Qin Guan had not thought about it for the time being. Every man is innocent and bears his sins. If the Han country can suddenly produce f404 directly, the problem will be serious.

Now, let's put this question aside. After all, there are too many Chinese push in the world. Only Eagle country has several projects to meet, including cow country and chicken country. At that time, we will show our superb matching ability.

It's no use worrying about this problem now.

When Spey has a thorough understanding, he can drive the progress of the whole aeroengine industry. We can talk about it at that time.

Qin Guan had to muddle along.

He talked with major Yang late at night, and the next day, Qin Guan and his party took general Jamal's special plane and began their trip to the holy country.

The holy country is in the south of Han. The climate here is hot and full of exotic customs.

Qin Guan had no time to enjoy the scenery here. After getting off the plane, he went straight to Kamla aircraft factory.

More than 40 miles away from the capital of the holy state is Kamla.

Simply put, it is directly called Kamla aircraft factory, and its full name should be called holy aviation joint venture. It is flat all the way from the capital to Kamla, and it is also a plain to Kamla.

Therefore, the biggest advantage of setting up an enterprise here is that it has a large space. You can add workshops at any time, and the runway is next to the factory.
