Rebirth of the Military Industrial Overlord

E2C, that is, the AWACS model currently in use by the US Navy, the latest modification of the "Eagle Eye".

This is a model improvement completed by the Americans in the early 1970s. In addition to the upgrade of the aircraft's flight performance, the biggest change is the radar system installed on it.

In the 1980s, all "Eagle Eye" early warning aircraft have been replaced with the latest AN/APS-138 radar developed by General Electric. It works in UHF UHF C-band, wavelength decimeter level, AMTD (Airborne Moving Target). Detection) system radar, linear frequency modulation pulse compression signal, large-scale integrated circuits and some digital circuits replaced the discrete components and analog processing on the previous model, replaced a new model of data processing computer, and adopted a new sidelobe pair Elimination technology improves antenna performance. The radar can automatically detect low-altitude targets on sea and land. The transmitter's alternative frequency has been increased to 10, with a new low pulse repetition frequency (PRF) operation mode, and the clutter improvement factor has been increased to 55db.

In terms of human-computer interaction system, it also conforms to the trend and is equipped with color display and graphical operation interface.

However, no matter how it is changed, it is still a traditional mechanical scanning radar. It still uses a Yagi rotating antenna to feed the radar and IFF signals to the equipment inside the aircraft through a three-channel rotating coaxial coupler.

Compared with the future trend of phased array, this mechanical scanning method has low data refresh rate and sensitivity, poor power conversion coefficient, so Americans have also been carrying out radar upgrades. Tan Zhenhua even knows that it will enter the 20th century. A century later, this type of radar will be replaced by the updated phased array system AN/APY-9 advanced ultra-high frequency phased array radar, and the refitted "Eagle Eye" model is E2D.

However, at this time, Huaxia does not have the ability to miniaturize T/R components. This subject was assigned to 4055 and 4014 by Tan Zhenhua not long ago. There is still a way to achieve technological breakthroughs and practical application. Go, and on the other hand? The successful development of the JY-9 S-band three-coordinate airborne radar indicates that China has the ability to develop an excellent three-coordinate radar on its own.

Compared with the development of a brand new radar from the ground up, moving JY-9 into the sky is obviously a feasible and cost-effective solution, and the development difficulty will be much reduced.

Tan Zhenhua unreservedly explained his idea to the people in the house and said that he had already put forward the related issues when he purchased JY-9 from 4038, and got the approval of the institute. The project has been launched. The delivery time of the prototype radar is expected to be within three years.

Compared with the "Air Police 2000", such an early warning aircraft is obviously inferior in technical performance. Even if it is successfully developed, it can only be said to have reached the level of the Americans in the 1970s. It has nothing to do with the leading ones. ——But in Tan Zhenhua’s mind, this plan is the only practical plan that allows China to have an early warning aircraft available in the 1990s, and with it, plus the blessing of the "Tan Zhenhua Cheats", what? Is it necessary to jump in the pit of "Faircon"? It’s unnecessary to waste 6 years, right?

Moreover, this project has an important impact-this is a ship-borne early warning aircraft. Although it can be used on land, the most suitable place to use it is on an aircraft carrier!

Aircraft carrier, that's the most important thing that Chinese generations have been thinking about...

It turned out that it was not a whim of this uneasy stinky boy to engage in carrier-based early warning aircraft, he had already planned the layout!

Lu Hesheng secretly sighed in his heart for the depth and breadth of the plan that his baby granddaughter liked, and said in a deep voice: "Since Zhenhua has started the radar development process, we will focus on the discussion today. The plane is ready."

When he said this, he had apparently acquiesced that he would continue to support Tan Zhenhua in this plan. Well, this is also a matter of course. I heard that this kid has been living with Vivienne illegally for some time. Since his baby granddaughter is right This stinky boy is desperate. As a grandfather, he naturally has to do his best to help the stinky boy. But there is the same thing. Recently there have been rumors that this boy and some women are unclear, such as the big lady of the BMW, The twin female stars of Xiangjiang, the daughter of the richest man in the Dai country... I don't know if Vivienne knows about these things, and what her attitude.

But brat, my old man can do my best to help you, if your brat dares to apologize to Vivian in the future, you can take care of your dog legs!

"In my experience, it is possible to change a carrier-based early warning/transport aircraft based on the "Yun 7". However, this size needs to be moved. The current size is too large for the ship to fit, and the structure is also It needs a big change." He said: "Director Chen, Chief Gong, let me analyze the specific parameters of E2 first, let's compare it with "Yun 7"..."

...

China, Beijing, Beijing Iron and Steel Research Institute.

"You came just right."

Seeing the big benefactor’s visit, Dean Cai’s face smiled brightly like summer flowers: “Tell you two important good news, we have successfully developed ultra-high-strength low-carbon alloy steel with a yield strength of not less than 785Mpa. And it has gone through a series of tests and passed the acceptance of national military standards, and even the official label has been given. In addition, DD6 has also completed laboratory preparation and its performance has fully met expectations."

"Oh, that's great." Tan Zhenhua couldn't help but grinning when he heard such a good thing when he entered the door. After all, he has spent a lot of money in the Iron and Steel Research Institute over the years, of course. Sales are also excellent value for money. The research institute has successively developed a variety of grades of ship steel, structural steel, and tool steel. It has done a particularly good job in combining China’s original advantage in the rare earth industry with alloy steel. Under the joint promotion of the Iron and Steel Research Institute and the Ningdu Special Steel Plant, these new high-performance steels have quickly achieved mass production and have been quickly introduced to the international and domestic markets because they are more cost-effective than similar products from foreign steel mills. Therefore, the international market share continues to increase, and Ningdu Special Steel Factory has become a star enterprise in Ningdu City and even Jiangnan Province.

There are many cooperation projects between Tan Zhenhua and the Iron and Steel Research Institute. Some of these projects are the development of new alloy steels, while others are the improvement of the properties and production processes of existing grades of steel. Most of these cooperation projects are conducted by Ningdu Special Steel Plant and research The institute jointly promoted, and the two sides also established a joint laboratory in Ningdu. Of course, he himself could not pay attention to the progress of every project, but there were two major projects that he personally investigated and promoted.

It is the two projects mentioned in the good news that Cai Qigong told him as soon as he met him.

He didn't care about politeness, and hurriedly pulled Dean Cai's arm and said, "Where are the samples? Take me to see."
