If it were in the past, Chen Xin would definitely focus on aero engine bearings, submarine towed sonar, anechoic tiles and other jishu that are more strategic to China, but this time if he wants to make money as soon as possible, trading these products is a little unworkable.

Because bearings, sonar, and anechoic tiles require long test cycles, and even if these products are eventually approved by the military, the final order will be quite limited.

To use a simple analogy, if the military takes a fancy to the aviation engine of the Strategic Fool Bureau and is ready to install it on the new generation of WS15 aero engine, but how many years will it take for the WS15 to really be put into mass production? Three or five years is not a long time. Even if it is finally put into production, the annual output of one or two hundred units is of little significance to Chen Xin, and according to the current international situation, the need for large-scale refitting of the Chinese military is not urgent.

So in Chen Xin's view, this kind of buying and selling is more like jishu assistance than making money.

The same is true for towed sonar and anechoic tiles, the construction period of a nuclear submarine is three or five years, and if it were to wait for a large-scale order from the military, the flowers would have been thanked a long time ago.

Therefore, compared with other parts orders, the T/R component (transmitting/receiving assembly) of active phased array radar is the most reliable and most suitable product for mass production of steel hammer.

As we all know, radar is an electronic device that irradiates electromagnetic waves from antennas to irradiate targets and receive their echoes, thereby obtaining information such as the distance, bearing, and altitude of the target.

The so-called active phased array radar consists of a large number of transmit/receive modules (T/R modules). Each transmitter/receiver module generates and receives its own radio waves.

Therefore, compared with ordinary radars, the beam pointing of phased array radar is very flexible and rapid, and one radar can form multiple independent beams at the same time, and realize multiple functions such as search, identification, tracking, guidance, and passive detection at the same time. Phased array radar has a very powerful multi-target engagement capability, which can monitor and track multiple targets at the same time, and the anti-jamming performance is far better than that of ordinary radar.

Since the 60s of the last century, phased array radar has become a key research and development equipment for military powers such as Europe and the United States. By the 70s, Europe and the United States and other countries had developed a variety of phased array radars. But due to the high cost. Due to the immaturity of the production of T/R components, it was not until the eighties that phased array radars were really equipped with troops.

Among them, the most typical representative is the AN / SPY-1 radar in the US Navy's Aegis combat system.

There are four radars in this set. into a hexagonal shape. Respectively installed in the four squares of the ship's superstructure.

Because the radar itself does not rotate. Completely by changing the phase of the beam, the airspace target in front of the radar is scanned at a rate of several times per second. The first-generation SPY-1A radar weighed up to 12,000 pounds per piece and had 140 modules on it. Each module contains 32 transmit/receive and phase control units.

The AN/SPY-1 radar began to be developed in 1965 and tested at sea in 1974, with the first system entering service with the U.S. Navy in 1983 with the Ticonderoga-class cruiser the first Ticonderoga (CG-47) and later into destroyers, and the Arleigh Burke-class destroyer, the first Arleigh Burke (DDG-51), entered service with the U.S. Navy in 1991.

At present, the X-band radar in the US theater high-altitude missile defense system has the largest number of T/R components on the shijie.

The radar consists of a number of small radomes and a 1,814-ton (4 million lb) phased array radar antenna, which covers an area of 384 square meters and has more than 20,000 sets of transmit-receive (T/R) modules, which are widely distributed in a way that allows the radar to track targets at very long distances to support the guidance of targets in the outer atmosphere of the Theater High Altitude Area Missile Defense (THAAD) system, which requires more than one million watts of power to function.

Therefore, the T/R component is one of the core components of active phased array radar, and its performance, reliability and development cost will directly affect the success or failure of the phased array radar system.

At present, the development level of T/R components is the most advanced in the United States, and as many as 25,344 T/R components are used in the X-band ground-based radar in the THHAD system, and 2,700 T/R components are used in the C-band ground-based phased array radar in the artillery positioning system (CDBRA), while in the spaceborne L-band active phased array radar, there are usually 2 to 100,000 T/R components, and there are as many as 10,000 T/R components used in strategic early warning aircraft. R components are stacked up.

For Shijie countries, the practical process of active phased array will mainly depend on the performance, price and other factors of T/R components, and scientists are also sparing no effort to promote the development of T/R components in the direction of miniaturization, lightweight, broadband, solid-state and integration.

Since the mid-nineties of the last century, great progress has also been made in the research of phased array radar T/R components in China, and the China Aegis system on the Air Police-2000 early warning aircraft and Type 052C missile destroyers is a typical representative. However, due to the fact that the domestic monolithic microwave integrated circuit (MMIC) jishu is not very mature, basically it is still dominated by hybrid microwave integrated circuit (HMIC), and there is still a considerable gap in the production of T/R components, especially in cost control and yield rate, compared with similar foreign products.

Therefore, as long as the war can provide the military with low-cost and high-quality T/R components, it will inevitably be favored by the military.

Moreover, there are thousands of T/R components of phased array radar, which have a wide range of applications in modern weapon systems, whether it is airborne phased array radar or shipborne phased array radar, and even the X-band radar in China's version of the National Missile Defense System (CNMD), there is a very large demand for T/R components.

These thoughts were fleeting in Chen Xin's mind, and Chen Xin hurriedly shouted into the room: "Steel Hammer, Steel Hammer ......"

Holding a piece of gold, the steel hammer staggered out of the room, and said, "Old Bean, what's the matter?"

Chen Xin said excitedly: "Gangyi, can you make the T/R component in the phased array radar?"

The steel hammer flashed his electronic eyes and said: "What's so difficult about this, as long as you give me metal gallium, I can make it casually." ”

Chen Xin's eyes lit up and said, "Okay, I'll go buy some gallium metal in two days and come back." ”

………………

The next day, Wu Jun took Osborne and the others directly to the Jiangcheng City Government to meet with Chen Yuanliang, the mayor of Jiangcheng City.

Came to Jiangcheng to work for more than half a year, with a small Cybertron Digital has become the most high-profile digital film and television special effects company in China, "Bring Her Eyes" and the upcoming "Country Teacher" have made Cybertron Digital in the limelight in many domestic film companies for a while, and Wu Jun has also accumulated a lot of fame in the Jiangcheng business community.

Compared with Wu Jun, Chen Xin is much more low-key, and the affairs related to the government are basically handed over to Wu Jun on weekdays, and Wu Jun is not expected to do anything, and many officials in Jiangcheng City have accumulated a certain amount of friendship.

However, this time I went to Jiangcheng Mayor Chen Yuanliang, but it was Chen Xin who told Wu Jun.

Chen Yuanliang and Mu Yunshan's father were comrades-in-arms at the same time as friends of life and death, and they received awards for their meritorious service in the self-defense counterattack in southern Xinjiang in the 80s of the last century.

Now that he is only fifty years old, he has become an important mayor of a vice-provincial capital city, coupled with the strong support of Mu Lao behind him, as long as there is no big accident, it should not be a problem to enter the highest bureau, as for whether he can become one of the elders, it depends on his chances.

Before leaving the capital last time, Mu Yunshan once told Chen Xin that if the company encountered anything in the Jiangcheng area, he could go directly to Chen Yuanliang, and Chen Xin asked Gangyi to investigate the net worth of the mayor of Jiangcheng City, who had a good reputation.

As a result, Chen Yuanliang has a total of three houses, and the total assets of all the immediate family members in the family add up to less than three million.

Chen Xin has a good impression of the mayor, as long as the science fiction film and television city project is completed in his hands, it may not be impossible to make this project a promotion for Chen Yuanliang in the future.

However, there is another important reason why I did not accompany them to visit Chen Yuanliang this time is that "The Village Teacher" is about to premiere in the capital, and Chen Xin needs to attend it in person. (To be continued......)
