Chapter 1865

This so-called turbofan-13 is actually a replica of the f404 engine produced by the Han country. Because Qin Guan has obtained a full set of production lines, it is this medium thrust engine that took the lead in making a breakthrough. But now, the engine of Han has formed a complete series.

Before the J-8, the maximum thrust of the engine was only five or six tons. Now it has been replaced by eight tons, which has immediately made a major breakthrough in the performance of this aircraft. Its maximum take-off weight is only 17 tons, and the normal air combat take-off weight is only 14 tons. In this case, its mobility is absolutely a reborn change, It is higher than the thrust weight ratio of J-6, so it will be particularly agile in air combat.

In fact, it has many congenital deficiencies, the most important of which is the long body. This kind of body makes it the bottom in rolling, even if it adopts differential flat tail. If it pulls too much overload, it is easy to pull itself apart.

Qin Guan knew that the development of this fighter should be regarded as the ultimate. Then, when he walked around to the front, he looked at the cockpit, and the avionics equipment in it had been completely replaced. He knew that 6601 Design Institute did its best, and they had changed the J-8 to the ultimate version.

However, Mr. Gu said that targeting the domestic and foreign markets is probably not enough. There should be great progress in the international market, but I'm afraid it's still not enough to talk about the domestic market.

With the J-10 and J-11 in China, we will definitely not want the J-8 again. No matter how the J-8 is improved and publicized, it is always the foundation of the second generation aircraft. After it has changed its engine, its flight performance has been improved. However, it is still unable to fight with the third generation aircraft. If our own J-10 and J-11 circle, the other party will not catch up.

Looking at the expectation on President Gu's face, Qin Guan finally said a sentence: "our northern industrial company will continue to promote this kind of fighter in the international market, but at home, it still depends on the meaning of the air force. The cost of this aircraft must have soared with such a change."

The previous turbojet-7 and turbojet-13 didn't have much money, but the cost of the current turbofan-13 is probably ten times that of it.

"Yes, the initial purchase cost is not low, but our engine has a long service life. On average, the price is not high in the whole service life cycle," Gu continued.

Hearing what President Gu said, Qin Guan nodded with satisfaction. Under the tide of market economy, finally, their 6601 Design Institute began to embark on the road of market, and they began to analyze problems from the perspective of users.

The turbojet engine used in the past has a low price, but its service life is also short, only 200 hours, while the current turbofan engine has a service life of more than 2000 hours.

In this way, in the whole life cycle of the fighter, if you use turbojet, you have to change the engine many times, but if you use turbofan, you can serve the whole life. In this way, although the initial procurement cost is high, it is not high in fact.

This depends on the perspective of users.

"Yes, I personally congratulate and sympathize with the progress of 6601 Institute. By the way, what new projects do you have next?"

For a scientific research institute, if there is no project, it means that it will decline. People must have something to do. If there is nothing to do, people will be completely abandoned.

What other projects are there in 6601 now? There are really no other projects. In addition to the improvement of this fighter, they really don't have any new projects. The whole design institute is worried about it.

The Su-27 fighter plane has also been transported away. At this time, they don't know how many people regret it. They knew that they should overcome all difficulties in the early stage and copy the Su-27. In this case, they still produced the most advanced fighter planes of the Han air force and Navy Aviation!

Now, the MiG-29 of the Xiong Kingdom has been in service and equipped in large quantities. The Su-27 fighters have long appeared in the vision of the intelligence agencies. Everyone has found that the new fighters of the Xiong kingdom are so similar to their previous ones. Unfortunately, they didn't seize the opportunity.

"Mr. Qin, do you have a new project?" Mr. Gu said excitedly.

Qin Guan won't come here for no reason. Although they have launched the jian-8-3 project and are intensively conducting test flights, Qin Guan despises this project. Moreover, looking at Qin Guan's expression, he doesn't know his own project at all. It shows that he has other tasks here.

"Let's go. Go in and say it's too cold outside." Qin Guan said.

It's too cold in the far north of the Han Dynasty. Although Qin Guan was a northerner and had stayed on the grassland for so long, he still didn't adapt to the severe cold here. He felt that although his body was in a thick military coat, his body still felt as if it was going to be frozen through. This was the bitter cold, It's like a cold wind can blow into a bone.

"Yes, please," said Mr. Gu. He got on the bus with Qin Guan and others and quickly went to the warm building.

The heating in the room sent out a hot smell. The warmth inside was in sharp contrast to the cold outside. After taking off his military coat, Qin Guan felt his body warm again.

"Welcome President Qin to inspect our work here. Now, let's listen to President Qin's guidance." President Gu said, which was very modest and embarrassed Qin Guan.

"You're welcome. I'm here mainly because I went to bear country this time and had some cooperation projects." Qin Guan said: "these projects want to ask us for help and work together."

Sure enough, there are projects!

"Mr. Qin, please go on." Mr. Gu's eyes were blazing.

"Everyone should know that jacques-38 is also equipped in our army," Qin Guan said.

"Of course, we've done this vertical takeoff and landing fighter, but we haven't done it in the back," Gu said.

When it comes to this, President Gu's face is proud. In that era, vertical takeoff and landing fighter was a project highly praised by everyone. Unfortunately, there were too few successful R & D in the end. Although we have not succeeded, we still have some technical reserves. Now, should we continue our research?

He looked at Qin Guan excitedly. If so, it was really a good breakthrough. Although it was not as wonderful as those conventional fighters, it also pointed out a new world for them.
