Chapter 1545

This flat phased array radar is soaked with too much sweat from 114 institutes. Moreover, they are still carrying out two projects at the same time. In addition to the Navy project, the air force's early warning aircraft plan is also under way.

Fortunately, many places are figured out, such as target screening, data processing, etc. in this way, they can learn from each other and accelerate development.

Now, I don't know how far the early warning aircraft project has progressed, but now the Han Aegis system of the warship has finally reached the stage of sea trial.

It was originally intended to use liquid cooling technology when developing the basic t / R components of phased array, but now looking at the arc cover, it shows that the liquid cooling technology is obviously not qualified, so it uses air cooling. The power of liquid cooling is greater and the cooling effect is good, so it can have stronger radar performance. In contrast, the air cooling is inferior.

Even so, it's better than nothing. Look at the western world, such as NiuGuo. Their type 82 is a declining aristocrat. In later generations, it's not until the new millennium that they have a special type 45 destroyer. Because they can't afford four flat plate phased arrays, they simply use a rotating base in the back. The real effect is much worse than the Aegis system.

Now, in the mid-1980s, the Han state has begun to test these technologies, and advanced aegis warships will be in service by the 1990s at the latest.

With these escort weapons, we can build an aircraft carrier.

"This warship will be launched in the near future for sea trial," said director Pan. "If it goes well, the test may be completed within a year."

"Well, our navy finally has advanced subsystems. This year, we can plan the next generation of destroyers," said Admiral Liu.

General Liu was originally born in the Navy, so he is most concerned about the Navy. With the improvement of the country's economic strength, the Navy will enter a period of rapid development sooner or later. Now, it's time to plan for the next generation of destroyers.

"General, we have begun to make breakthroughs in many subsystems," director Pan said. "However, there is still one biggest weakness, waiting to be supplemented."

And a short board? Before General Liu could speak, Qin Guan asked strangely, "what short board?"

Qin Guan had long noticed the system construction of the Navy and carried out a series of pre research projects in advance. Now he has achieved fruitful results. What are the shortcomings?

"It's the power system," said director Pan.

As the director of 7701 Research Institute, Mr. Pan is definitely old. However, what he said now surprised Qin Guan: "the power system has been solved? Didn't I put forward it and change it to marine gas turbine on the basis of Spey?"

There is already a mature and reliable Spey engine in China. Improving on this basis is the scheme put forward by Qin Guan. However, later, Qin Guan had too many things to do, so he didn't pay attention to this aspect. Now, hearing what Pan Lao said, Qin Guan was very curious.

Pan Lao's face was ashamed: "yes, at that time, we planned to improve the gas turbine on the basis of Spey. However, the Navy's scientific research funds were limited and could only support one project. Therefore, the Navy focused on the development of air defense system, and the marine gas turbine was put down temporarily."

The funds are limited, and the navy is the most expensive. Although many projects are carried out by Qin Guan, such as the training system of the naval aviation force, there is no money for those deck operators invited from Eagle country and the new batch of fighters ordered.

Moreover, it doesn't seem very important to change Spey to gas turbine. Now the Navy's most urgent thing is the shipborne air defense system.

Qin Guan nodded: "yes, capital has always been a major problem perplexing us. But now, we must enter the track of pre research. If there is a problem with capital, our northern industrial company can provide some R & D capital for us. When R & D comes out, we can also sell it."

Suddenly, Qin Guan remembered something and patted his thigh: "since it hasn't started yet, let's just use our latest high thrust turbofan engine to transform it."

In the original plan, there was such an idea. Now the new generation of turbofan engine in Han country is actually the imitation F110 engine. The expansibility of this power system is quite high. To a certain extent, it also has a great origin with the current star power, lm2500.

Lm2500 gas turbine comes from ge9 core machine of General Electric Company. This core machine is loud. Initially, ge9 core aircraft derived F101 large bypass ratio military afterburner turbofan engine, which was used for B1B supersonic strategic bomber.

Later, after the conversion flow of ge9 was further reduced, GE15 core machine was developed. GE15 core machine has derived the vortex jet model yj101. Is the relationship very chaotic?

What's more, Ge enlarged the low-pressure compressor of yj101 into a fan and developed the f404 medium push turbofan engine. The fan of f404 is amplified and combined with the small culvert ratio model of F101, which is F110.

Of course, this is not over. The cmf56 large bypass ratio turbofan engine jointly developed by general electric and SNECMA is also based on the ge9 core engine, and this engine is also a typical representative of the third civil turbofan engine, and has prepared many airliners.

This reflects the great power of the core machine. A core machine can create a lot of power to solve the problem of heart disease.

Now, the F110 engine imitated by our own surveying and mapping is about to enter the mature stage. On the basis of this engine, the gas turbine developed is completely close to the lm2500. The passenger plane engine with large bypass ratio developed on its basis can be used in our own Yunshi.

In that case, why do you need the second-generation Spey? Just enter the serial number of the third-generation machine directly.

"This heart is of great importance. We must develop it as soon as possible. After the development is completed, we can not only use it for ourselves, but also equip our exported warships," Qin Guan said.

Apart from other things, the warships ordered by Shengjie from its own side are equipped with Eagle lm2500 gas turbines. Naturally, it can also be equipped with its own gas turbines in the future.

This time, the starting point is higher.

"Well, the NiuGuo Navy is about to dock at the port. Let's go and meet him." General Liu said. At this time, his face is smiling and his men are defeated. This time, let's see how you can be arrogant.
