Chapter 387 The first domestic phased array radar antenna
The port of Qatar.
Serge was there waiting eagerly.
Finally, the Maersk cargo ship entered the port. When the cargo ship stopped, Serge couldn't help but rushed onto the ship and rushed to the lower deck.
It’s empty down there, there’s nothing!
Serge’s expression changed drastically: “What’s going on? How could this happen?”
"What's wrong?" Ali was a little confused: "Is there any problem here?"
“Where are the goods here? Where are the goods here?”
"There is no cargo here. All the cargo is on the upper deck. We have already counted it."
Serge could only feel the rumbling in his head.
I've been fooled, I've been fooled!
Ge Guangle also came to the lower deck. Seeing that it was empty, his expression changed drastically.
After spending an extra 300 million US dollars, they just wanted to bring these fighters back. What was the result? As a result, the plane disappeared!
“Mr. Serge, we have done what we should do, and we hope you can make up for our losses and give us production again.”
"Of course it's impossible! We have done our best this time. The losses caused will be borne by you. We will ensure the safety of the remaining fifty."
“No, how could you do this?”
The two began to quarrel fiercely in French.
As for the other side, in the aviation base near Abbas Military Port, some special goods were stored in the warehouse.
"This is really a perfect operation." Karim said to Qin Tao with emotion: "We..."
“Such an action can only be carried out once, and the preparation must be well prepared and the moral high ground must be taken.” Qin Tao said: “If it weren’t for these Phantom 2000, I would not have made this plan.”
Karim nodded.
Husseini on the side spoke: "Mr. Qin, what should we do with these fighter planes next?"
"Ah San, the Pyramid Kingdom, they are all equipped with Mirage 2000 fighters. Next, you can contact them to see if they are interested in buying." Qin Tao said, "Of course, you can also store it here first and wait until After this incident has passed for a while, you can use it yourself.”
Unfortunately, the Rainbow Nation is actually more suitable, but the current Rainbow Nation no longer has this capability. A place that has degenerated from a developed country to a developing country has no need for such fighters.
"Yes." Husseini nodded: "We will transfer all the US$500 million obtained this time to the account of Mingzhou Group. Please transfer it to the J-31A development unit."
Anyway, the money came for free, so they used it very generously.
"Okay, we will complete the relevant procedures and contracts in secret. Please rest assured that if this fighter aircraft is successfully developed in the future, you will definitely be the second user to equip it. By the way, you must also make relevant preparations here. .”
“Understood, we will announce our own fighter development plan in a while.”
“And those two women.”
"Um."
A few days later, two female corpses were found on the outskirts of the Parthian capital. The local police reminded foreign friends that they must be careful not to go to remote places alone, as this is prone to accidents. Also, they must respect local customs and dress appropriately. Be polite and so on.
This matter has passed like this.
Qin Tao and Xu Zhengyang had already left Parthia and inspected the progress at Gwadar Port. When they planned to return home, they met with Lao Ba's naval officer Mahmoud again.
"The design of your J-31A is perfect. However, after evaluation, we believe that the development of this aircraft is too risky. Therefore, we finally decided to continue the Saber 2 project." Mahmoud and Qin Tao said of the Air Force's choice: "This project is the most suitable for us."
Lao Ba has always been pragmatic. He has no choice. He only has so much money in his pocket, so he must be careful with his calculations. This J-31A sounds very powerful, but there are too many technical difficulties that need to be overcome, and the project is too risky. big.
After the visit, they finally looked back at the 132 Factory project and found that this fighter upgraded from the J-7 has become more and more mature and can fully meet their needs.
So, they stayed in the Land of Abundance, continued research on this project, and eventually signed an agreement to continue cooperation.
When he heard this, Qin Tao showed a satisfied smile on his face. It seems that the Xiaolong fighter will continue to advance steadily, and Lao Ba will become its largest user. At the same time, as long as the research and development can be completed as soon as possible, then, They can take the lead in occupying the market and gain opportunities before the trend of second-hand F-16s and MiG-29s arrives.
Of course, these are aviation affairs and have nothing to do with Qin Tao. Mahmoud just said a few words casually, and then turned to a more important topic: "The funds related to our warships have almost been raised. , we will be able to place an official order in the near future, and I hope you can start work as soon as possible to manufacture this kind of advanced warship for us."
“Of course it’s no problem.” Qin Tao immediately agreed with his chest high: “As long as your funds are in place, we will start construction immediately!”
After inspecting the construction site of Gwadar Port for a few days, Qin Tao embarked on his return journey. This trip lasted another seven or eight days. He was always running around outside, and his wife at home was about to give birth to a baby. .
However, Qin Tao did not stay at Huating's home, but came to Mingzhou Shipyard.
After repeated testing, Ship 115 has finally completed all projects and is now about to be delivered to the Navy!
On this day, the flags on the 115th ship were flying as if it were a festival.
Captain Wang Qing is the most excited one.
"President Qin, you are here. You participated in our groundbreaking ceremony and sea trials. Now that we are delivering the troops, it would be a pity if you don't come!" After meeting Qin Tao, Wang Qing couldn't stop talking. Absolutely.
Qin Tao still has fresh memories of the sea trial. At that time, when he went to sea for the first time, he found a big shark underwater and kept forcing it away.
"However, you still didn't notice our sea target shooting test a week ago. It was spectacular. When the anti-aircraft missile flew out of the launch tube in front, all of us looked like a giant dragon in front of our eyes. It's like rising!" Wang Qing continued.
The sea target shooting test a week ago was not only a final test before the warship was put into service, but also to let some people with ulterior motives know that when it comes to air defense, the navy's shortcomings have been made up!
When the missiles they launched successfully hit a target 80 kilometers away, who would dare to cause trouble?
The navy has become stronger, this is the confidence!
“Yes, it’s such a pity.” Qin Tao said, “By the way, who are the leaders attending the ceremony today?”
“Of course it’s Leader Wu, it’s getting late, we have to get there quickly.”
"Our motherland's navy has grown from scratch. We have gone through decades of ups and downs. In training and fighting, we have written our loyalty to the motherland. No matter in the north or in the south, our navy will move forward indomitably. !”
"However, it is not enough to rely on our firm will and loyalty. We also need advanced weapons. We need to build a strong navy and protect the waters of our motherland. Now, the one that is about to join our navy is the first ship with a displacement of more than A five-thousand-ton main battleship!”
“At the same time, it is also the first professional regional air defense ship of our navy. Its service will fill the air defense gap of our navy and become a symbol of our strength!”
At this moment, Qin Tao was also very excited.
That’s right, this is the Navy’s first main battleship with a displacement of more than 5,000 tons. The previous 051 of more than 3,000 tons and the 052 of more than 4,000 tons will all become history! And the regional air defense capabilities it provides are lacking in other warships.
"Now, I announce that No. 115 has been officially named Shenyang! The flag presentation ceremony will be held below!"
The military band was playing accompaniment and the honor guard was advancing. At the front was Wang Qing with an excited face. He took the military flag from Wu Shengli's hand and walked towards the warship.
Warship No. 115 officially joins the navy!
The sound of whine sounded, and the huge warship left the port of Mingzhou for the last time, preparing to head north to the port where it needed to berth. In front of and behind the warship, neatly dressed sailors stood.
At the outfitting dock not far away, Ship No. 116 is still undergoing final outfitting work. Soon, Ship No. 116 will be launched into the water, undergo sea trials, and then join the navy.
“Taozi, how do you feel at this moment?” Wu Shengli asked Qin Tao after the warship had gone away.
Looking at the leaving warship, Qin Tao had longing on his face: "I seem to have seen a super aircraft carrier with a displacement of 80,000 tons sent away from us."
With a displacement of 80,000 tons, a super aircraft carrier!
These words made Wu Shengli feel complicated.
Where is the motherland’s aircraft carrier? Wu Shengli was full of expectations, but Qin Tao had always firmly believed that that day would definitely come.
"When the time comes, our stealth carrier-based aircraft will be deployed on the aircraft carrier and take off through electromagnetic catapults. No matter where in the world our people are in danger, the navy will arrive. Our leaders will be there when encountering an emergency. When the situation is reported, the first thing to say is, where is our aircraft carrier."
"Yeah, I don't know if I can see this day coming." Wu Shengli sighed: "Taozi, you did a great job on this trip to Parthia. Many people are saying that only you can Do this kind of thing."
“Many people?” Qin Tao was stunned.
Wu Shengli smiled, what is Qin Tao worried about? Leak? Of course, it is impossible for him to reveal the secrets to many people he talks to.
"With the huge funding of US$500 million this time, the J-31A project will continue. Many people are curious about how you, a shipbuilder, have made a push in the aviation industry. Moreover, technology The indicators are still the highest.”
“Well, when we pass by No. 14, let’s go in and take a look.”
Qin Tao nodded. Of course he knew what Institute 14 was doing. It seemed that the domestic phased array radar had made great progress.
At this time, while talking, the two of them had already walked to the welding workshop of the natural gas ship. It can be seen that there are obviously many more people in the workshop than before.
Cong Ju saw Qin Tao coming and immediately greeted him warmly.
“Mr. Qin.”
“Well, let’s stop by and have a look. Why are there so many people here?”
“Mr. Qin, have you forgotten? We have an agreement with Huating Shipyard to help them train welding workers at Yinwa Steel.”
Qin Tao suddenly realized: "Yes, of course I remember. It seems that these workers are already skilled in the operation."
“Well, according to our previous agreement, these workers have to work for us for a few more months, so that they can master their skills more proficiently.”
Qin Tao nodded, very satisfied with the arrival of these free labor forces.
“Our first natural gas ship with our own patented technology only has the last box left. It is expected that this natural gas ship will be delivered to customers by the end of this year.”
Qin Tao continued to nod: "This is a new beginning for us. Please inform me in advance when the time comes, and I will definitely come here to participate in the delivery ceremony."
Cong Ju smiled and did not answer, obviously she did not trust Qin Tao's words.
If Qin Tao says he wants to come, will he definitely be able to come? It may not be somewhere in the world by then!
Leaving the natural gas ship production workshop, Qin Tao walked around in other places, and finally got into the car with Wu Shengli.
By the time we arrived at the 14th school, it was already evening.
“Wouldn’t it be inappropriate for us to come over at this time?” Qin Tao said, “It’s probably time for dinner.”
“Let’s go take a look first.” Wu Shengli insisted.
So, when several people put on their white coats and walked in after being dust-free, Qin Tao was surprised to find that although it was already dinner time, no one was eating here, and they were still busy working!
What surprised Qin Tao even more was the huge 4-meter by 4-meter flat plate standing in their laboratory.
This flat panel is made of aluminum alloy as the skeleton. At this time, a dozen technicians in white coats are standing on the scaffolding, installing something on this flat panel. Each of them is in a small honeycomb-like unit, small and compact. The T/R assembly is accurately held in place.
“Old Ben, has this first shield been built?” Qin Tao asked in surprise.
Hearing his question, Mr. Ben who was directing the installation work turned around and looked at Qin Tao and Wu Shengli with a smile on his face.
“Yes, we are doing the final installation work. Once the installation and debugging is completed, we can start experiments on land.”
This is also the first active phased array radar in China!
Wu Shengli looked at the tablet with excitement in his eyes.
“Lao Ben, this project of yours is what the Navy is most looking forward to! As long as it passes the test and the four-sided shield is produced, our Navy can start building the first professional air defense ship with a four-sided phased array radar!”
Although No. 115 has been put into service, it is not professional after all. It only has a passive phased array radar, which has to be rotated to complete the full airspace search. Because it is blocked by the bridge, there is an air defense blind spot in front.
It would be great if the four-sided phased array radar could be installed on warships.
“Yes, Mr. Ben, our Mingzhou Shipyard has begun to design specialized air defense warships based on our 346 radar and Hongqi-9 missiles. We are ready for everything and only need the east wind.”
Wu Shengli glanced at his son-in-law and knew that there was something in his words.
Specialized anti-aircraft warships, they have already designed them and are just waiting for bidding!
This time, are there any units competing with them?
Those units will probably retreat in the face of difficulties!
After all, 051C, 054, and the warships manufactured for the Oriental Pearl were all designed by Mingzhou Shipyard. Now, no one dares to question the strength of Mingzhou Shipyard, and they seem to have designed all the navy’s warships. Got it all covered.
Mr. Ben smiled and said, "Mr. Qin, it seems that we will have to work closely together in the future."
"Of course, Mr. Ben, according to our design plan, the layout of the four-sided phased array radar is different from the American Ticonderoga class and similar to their Arleigh Burke class. Your antenna must also follow this plan. to optimize.”
The Americans are the first in the world to develop this kind of professional air defense ship. However, the layout of the four-sided phased array radar is very particular.
The Ticonderoga-class cruiser uses a simple arrangement of front, rear, left and right, each responsible for a ninety-degree fan-shaped area. It seems to be suitable, but in fact there is a problem: when the warship rocks back and forth in the sea, the four shields radiate The electromagnetic waves that go out may not fully cover the entire airspace.
To put it simply, if you swing from side to side, if the shield on the left is turned upward, it may not be able to sweep the sea surface, and if the shield on the right is turned downward, it may not be able to scan the top of the head.
Therefore, when it comes to the Burke-class destroyers, the installation positions of the four-sided phased array radar become the left front, right front, left rear, right rear, and they are not placed vertically, but with a certain inclination angle. In actual use, the layout plan is the most appropriate.
Our own Aegis battleships, of course, also need to be arranged in this way.
Mr. Ben nodded: "We originally planned to determine the pros and cons of various layout plans during the land test. Now, since President Qin has designed the warship based on the Burke-class layout, it means that this layout should be more suitable. We will also optimize based on this arrangement.”
While everyone was communicating, they continued to watch the progress of the installation. Qin Tao couldn't help but said, "When you install this phased array radar, can't you install it flat?"
To stand it four meters high like this, you need to use scaffolding. If you lay it flat and install it, the big guy can just lie down on it.
Faced with this idiotic question raised by Qin Tao, Mr. Ben was very patient.
"If it is installed flat, it means that some of us need to step on it. The aluminum alloy frame will be deformed, or the installed components will be stepped on to change their position. It will be a disaster for debugging. .”
“Also, we not only need to install it on the front, but also need to wire it on the back. The current operation is that people are doing it on both sides.”
Qin Tao then realized what he was doing and walked to the back. As expected, there were many people busy there.
“It’s such a hard work for everyone, and they still have to endure hunger. I can already hear someone’s stomach growling.”
"There is no way. The installation of our phased array radar requires very high cleanliness. It takes time for everyone to put on and take off their clothes and undergo dust-free treatment." Mr. Ben said: "Everyone will work for a while longer and wait until seven or eight o'clock. , we’ll get off work.”
“Okay, let’s wait and then go have dinner together.” Wu Shengli said.
Watching the technicians working hungry, Wu Shengli was very moved.
“How many units are there on this antenna array?” Qin Tao asked.
At the time of the bidding, it was said to be more than 4,000, but the specific amount was not clear.
"To be specific, it is 4768." Mr. Ben said: "One-third of them are gallium arsenide and two-thirds are bipolar silicon. This compromises both performance and cost. After this In the production of area phased array radar, we are also constantly exploring and improving the production process of gallium arsenide. When mass production is carried out in the future, the proportion used may be higher."
Bipolar silicon is easy to make, but its quality is low and its performance is poor. Gallium arsenide is difficult to process, but its performance is high. At the beginning, a compromise was made under Qin Tao's suggestion.
“Yes, we need to mature this technology quickly. Not only the navy’s warships need it, but the radars of our navy’s carrier-based aircraft also need to move towards active phased array radars.”
Not only warships need to use radar, but also fighter planes. The demand for fighter planes is even stronger, especially the J-31A. This aircraft has to reach the level of a fourth-generation aircraft. How can it be justified without a phased array radar in the sky? .
“Fighters also need to be used?” Mr. Ben frowned.
“What, can’t you?”
"If it is to be used by fighter jets, the existing T/R components will still not work. Either a newer generation of gallium arsenide or gallium nitride will be used, so that the volume can meet the use of the aircraft, especially the latter, which should be the most suitable. .”
“What is gallium nitride?” Wu Shengli was a little curious.
"Gallium nitride is a compound made of nitrogen. This nitrogen is a gas molecule with a molecular weight much smaller than that of arsenic. The atomic volume of gallium nitride is only half that of gallium arsenide, and, more importantly, nitride Gallium is an extremely stable compound with high hardness and a melting point of 1700 degrees Celsius. After a device is made of gallium nitride, it will not deform when stepped on, and it can work in a high temperature environment of 800 degrees Celsius. The breakdown voltage of gallium nitride is respectively It is several times and dozens of times that of silicon biodes and gallium arsenide, which can easily increase the power density of the array."
Speaking of these, Ben Lao was in high spirits.
"Take our phased array radar as an example. If the components inside are replaced by gallium nitride, even if the quantity remains unchanged, the search distance can be increased by at least 1.7 times, which means a search distance of 800 kilometers can be achieved to explore ballistic trajectories. There is no problem with the missiles. Even at close range, it can directly concentrate energy to burn through the electronic equipment of anti-ship missiles!"
Wu Shengli opened his eyes wide, so awesome?
"However, this technology is difficult. Even the United States currently uses second or third generation gallium arsenide in airborne phased array radars, and gallium nitride is still under development. Here, Due to lack of funds…”
“Let’s find a way to solve the funding problem.” Qin Tao said: “When the funds are in place, all of us 14 will not have enough technical strength to carry out gallium nitride research?”
Think about the future aircraft carrier with electric bombs, paired with the J-31A, and this kind of phased array radar, how exciting it would be! Therefore, Qin Tao can't wait. Just follow the path of the International Joint Fighter Group and use other people's funds to develop your own technology!
“We are not good enough ourselves and need to cooperate with domestic material experts. However, as long as we have funds, the rest is not a problem!”
“Okay, let’s settle it then.”
