Chapter 2758

Thinking about those things in later generations, Qin Guan can laugh happily. Various problems emerge one after another. Even there was a boiler explosion during the trial voyage. The reason they gave was that they used refractory bricks made in Han Dynasty!

People in the state of big Xiong also like to splash dirty water like this. However, the state of Han doesn't care. Even Qin Guan really wants to provide them with unqualified refractory bricks. It's good to blow them up. If you change the boiler, you have to cut open the aircraft carrier deck. Another half a year has passed. Moreover, at that time, Xiong Guo still provided the Gorshkov, which was a Kiev class No. 4 ship with greater displacement and renewal. The other ships had various faults during more than ten years of navigation, and finally retired. Only the Gorshkov had refitting value.

But not now. The Gorshkov is still in service in the bear Navy. Only the Kiev and novorossisk have been transferred to reserve service. Drag them out and disassemble them. It is estimated that there will be more faults. Let them toss about slowly and watch a good play by themselves.

Qin Guan gave them a big gift. How should they repay themselves?

"Mr. Qin, please come here and have a look at the new engine we have developed." Dr. Che Jin said.

Liulika design bureau is also first-class in Xiong Guo. Only they have the most advanced engine R & D capability. The project code is product 20 and the external code is AL-41F. This is the power system developed for the fourth generation machine of Migao Yang design bureau!

Before the collapse of xiongguo, during the decades of development, xiongguo had many excellent design bureaus and created many representative works. Now, xiongguo Design Bureau blooms everywhere, and there are eight leaders in the grand situation.

Krimov Design Bureau has rd-33 medium thrust turbofan jet engine; Liulika Design Bureau has AL-31F turbofan engine; 3. Soviloyev Design Bureau has D-30 high thrust turbofan engine; Isotov Design Bureau has tv3-117 turboshaft engine; Kolesov design bureau is rd-36 turbojet engine; There are Kuznetsov Design Bureau, Tumanski Design Bureau, Ivchenko Design Bureau, etc.

As for production enterprises, they are mainly Saturn, salute and progress.

However, a few years later, after the great bear country's aero-engine industry has been reorganized, there are only two left, namely the salute and the liulika Saturn aero-engine consortium. It can be seen how fierce the competition in the bear country's aero-engine industry is.

Many of those failed engine design bureaus have been eliminated. This does not mean that their technology is not enough, but their engine impact objects are different under the distribution of bear state in that year.

Now, Qin Guan wants to start from liulika Design Bureau and attract their talents to the state of Han. Even liulika design bureau is no exception. Now, after Qin Guan's friendly performance, he has finally obtained the friendly performance of the other party. He is going to visit their most important motivation project.

The third generation engine, represented by AL-31F, has a thrust of more than 12 tons and a thrust to weight ratio of 8. Of course, according to Western standards, the thrust to weight ratio is only about 7.

As for the fourth generation engine, the representative work is AL-41F, with a thrust of 18 tons and a thrust to weight ratio of 10, which is comparable to Eagle's aeroengine.

Now, this kind of engine has been manufactured.

Of course, for the aeroengine, manufacturing is only the first step of the long march. It is not the end when it is installed later, continuously test flights, expose problems, solve problems, and finally pass the permanent test run. After assembling the army, many problems will appear. It is not the success of engine research and development until all problems are solved.

The research and development of this engine began in 1981. By 1987, the engine was assembled and began to carry out tests. Some flight tests were carried out on the tu-16 subsonic bomber and the supersonic interceptor MIG 25pd. Now, one of the tested engines is displayed in front of Qin Guan.

"On this engine, we have adopted a full digital control scheme, changed the cycle parameters, used high load turbine and compressor blades, and strengthened the single crystal structure through fiber carburization. It is our most advanced engine, with a maximum military thrust of 12 tons and an afterburner thrust of more than 18 tons. If it is used on Su 27K, the performance of Su 27K can be greatly improved immediately A substantial increase, "Dr. cheking said.

As the chief designer of this engine, Dr. Che Jin is quite confident.

"This engine is not used on Su 27K, is it?" Qin Guan said. "I remember that I went to Migao Yang Design Bureau before."

Hearing Qin Guan's words, Dr. Che Jin was embarrassed. After all, the project of Michael Yang was confidential. Unexpectedly, the other party let president Qin see it. It seems that the whole bear country has no secrets to them.

"Moreover, it's too big for Su 27K." Qin Guan continued, "unfortunately, I'm afraid this engine has no place to use."

Qin Guan said that everyone present sank. Their engine is the pride of the whole liulika Design Bureau. However, it has spent 500 million so far, and it may take more than one billion to succeed in research and development. The great bear country does not have this economic strength.

In other words, this advanced engine has no ability to develop, including the new fighter at Migao Yang. If the enterprise develops it by itself, it can't go on at all.

That huge empire is gone!

In fact, the fate of AL-41F engine has ended so far. No matter how advanced the data on paper are, it is impossible to succeed in this environment. This is the helplessness of a country after its decline.

When Qin Guan said this, the designers present felt a trace of coolness from their hearts.

"Yes, it's not suitable for the Su 27K. It needs a new model of fighter to match," Dr. cheking said.

"Liulika design bureau is a design bureau with advanced technology and glorious history." Qin Guan said: "Many advanced engines have been born here, especially AL-31F. I admire all of you here. I respect the scientific and technological personnel most. I am also glad that you can show me the most advanced engine. If you have the opportunity, I would also like to invite you to visit China and see our most advanced engine projects."

Flickering started again. Qin Guan came here and proposed to improve the aircraft carrier. It's just a kind of rhetoric. It's just a whim after the tide of blood. The real purpose is still to dig talents!
