This cannot be blamed on anything else but that the current vacation is too short.

In the new millennium, some geniuses came up with the idea of ​​taking two weekends in reverse to form a seven-day holiday. Now, the New Year holiday is still three days. These three days of holiday are very stressful for many people.

Take Qin Tao as an example. After New Year's Eve, he has to go back on the first day of the Lunar New Year. When he arrives at Mingzhou Group, it is probably the night of the first day of the Lunar New Year and he has to hold meetings all night. On the second day of the Lunar New Year, he has to go to the capital.

We will discuss the bidding process together. After the meeting, the bidding will probably officially start on the fourth or fifth day of the new year.

"Dad, Dad, do you think this tiger dumpling I made is good?" At this time, Qin Haiyang came over with a special-shaped dumpling to show off to Qin Tao.

In the past, although Qin Tao also took time to see his son, he always felt that there was some distance between him and his son. His son was also afraid of him and would not kiss him. But now, his son has become completely familiar with him.

As he said that, he sat down on his lap.

Qin Tao nodded: "Yes, it's really good. By the way, when you made the dumplings, did you put a coin in it?"

"It's wrapped, just wrap it in my tiger dumpling."

Qin Tao thought it was a bit funny. If you put it in this dumpling, would it still make sense? However, he didn’t want to see through it, so he nodded: “Okay, let’s see who is so lucky and can eat coins.”

Dumplings.”

"Yeah." Qin Haiyang nodded vigorously.

"Ocean, the water is boiling, it's time for us to make dumplings!"

"Yeah." Qin Haiyang ran away again.

Looking at his son's back, Qin Tao knew clearly that this was probably the happiest Spring Festival his son had ever had, but it was a pity that he had to leave again.

At the dinner table, Qin Haiyang really ate the dumplings with coins, and he was extremely happy. Qin Tao also took advantage of this moment to hesitate and said: "Hayang, tomorrow is the first day of the Lunar New Year. Should we go back to Mingzhou?"

Are your grandparents going to pay New Year greetings?"

"Okay, okay!" Sure enough, children are always easy to deceive.

Zhao Ling looked over with questioning eyes. Qin Tao nodded, he was very busy!

On the first day of the Lunar New Year, in the evening, the conference room of Mingzhou Shipyard.

"Mr. Qin, you can rest assured. Our 052C destroyer will definitely be recognized by our superiors. Our design is first-class. Even if it is not inferior to weapons, it is just faster than ours."

"With the same power and the same hull, how come our destroyers are faster than those of our brother units?" Qin Tao was a little curious.

"Because the warships of the brother units were launched earlier, the bottom of their ship was not very smooth." Zhou Yongfei said, "They did not have time to clean it up."

Qin Tao shook his head helplessly: "What we are competing for is real ability. We must let the navy see that the performance of our warships is much better than that of our brother units."

"Mr. Qin, if it compares with the real performance, I have an idea." Yang Dawei said.

"any solution?"

"Fly our J-31A over and see which warship can detect it earlier."

Qin Tao's eyes suddenly lit up: "That's right! This is how you win the right to be fair! Although there is no stealth coating yet, the aircraft body also has a certain stealth effect."

According to Qin Tao's plan, the stealth coating on the F-117 will be available in 1999. At that time, the J-31A will be spray-coated. However, even so, it can be pulled over and given a try.

After all, coating is only one aspect of a fighter's stealth. The design of the body's surface is also very important. If we briefly talk about some specific data, the contribution of stealth coating to stealth performance accounts for about 20%, mainly due to

The aircraft body reflects radar waves in other directions, so it doesn't matter even if there is no stealth coating.

"I heard that relevant domestic departments have developed a stealth coating, but I don't know how effective it is," Yang Dawei said.

Qin Tao's eyes lit up: "Regardless of whether the effect is good or not, let's paint our J-31A first! Let them know now!"

"I'll go." Zhao Ling, who was sitting next to Qin Tao, spoke.

Although it has not been officially announced, when Zhao Ling appeared in the meeting today, everyone will understand what it is. Zhao Ling is engaged in Hongqi-16, and 052C is equipped with Haihongqi-9. Moreover, Zhao Ling is also big

Fangfangdi sat next to Qin Tao.

Therefore, Zhao Ling is not sitting here as a military R&D personnel, but as Qin Tao's assistant! It seems that Mr. Qin will often take his wife around in the future.

As for Qin Haiyang, he had a great time with his grandparents today. He didn't need Qin Tao and Zhao Ling to take care of him.

Qin Tao nodded, watched Zhao Ling leave, and then continued: "Aside from the advantage in detecting stealth aircraft, what other overwhelming advantages does our warship have?"

Needless to say, of course, it is the ability to deal with multiple targets. Compared with a large shield with four sides and a large rotating shield, there is a big difference in the target refresh rate.

"If the superiors are willing to dispatch a large number of target drones, it will reflect the performance of our warships. The more target drones dispatched, the better. They can be high or low, in different directions and at different heights."

A large rotating shield cannot track so many targets in time. A four-sided phased array radar does not need to rotate and can keep an eye on the target at any time.

Qin Tao nodded: "Yes, we request the use of a large number of target drones. If the navy is too expensive, we can also provide some small drones. The more, the better. It is also a test of the air defense performance of our warships. What else?"

"Although we are air defense ships, we have rich experience in building warships and the ships have low noise, which also has advantages in anti-submarine warfare." Another technician said.

"Well, that's right. Even though it's an air defense ship, it also has to conduct anti-submarine warfare when necessary. We have to show our advantages in anti-submarine warfare."

The meeting lasted until late at night, and early the next morning, the Mingzhou Group's charter flight flew to the capital.

In order to avoid suspicion, Qin Tao did not live in his father-in-law's house, but stayed in the guest house in the Gongzhufen compound with Yang Dawei and others.

As soon as I settled in, someone came to visit me.

"Mr. Qin, you are here too. I'm here to chat with you. Do you have time?"

Looking at the person in front of him, Qin Tao nodded: "Of course, even if there are other things, I have to turn it down. Director Sun, please come in!"

Their bidding rival, Sun Xuewen, the director of Bincheng Shipyard, actually came to visit Qin Tao. He didn't look like a competitor at all, but like a good friend.

"Mr. Qin, I heard that you have received a large number of orders for container ships?" Sun Xuewen knew that Qin Tao didn't like to waste time. After entering the door, he went straight to the topic.

"Yes, we have already started designing a new 18,000-ton container ship. However, our slipway is too busy and we are currently considering expanding the Chongming Island Shipyard... Director Sun, how many orders do you want?

?”

Shipowners who do not have container ships can no longer trust San0 Heavy Industry, and all large orders for container ships have gone to Mingzhou Group! Some time ago, in order to show goodwill to Mingzhou Group, San0 even wanted to send container ship orders as gifts.

Giving it to Mingzhou Group, now it seems, is a joke. What Mingzhou Group wants, there is no need for San0 to deliver it. The customer will deliver it directly to their door, so why need San0's favor.

Now being used as a favor by the Mingzhou Group is not bad.

"Mr. Qin, if you can't digest these orders, we can also help you." Sun Xuewen said with a smile.

"Of course there is no problem with this, but we have to wait for a while until our first ship is launched and put into normal operation, and only after the ship owner approves it can we allocate the next orders. After all, we have to ensure the safety of navigation. But we can't

Making the same mistake as the islanders did.”

"Well, Mr. Qin, just your words are enough." Sun Xuewen said, "We will elaborate more when we need you in the future."

After saying that, Sun Xuewen stood up.

"What, Director Sun, are you leaving?" Zhao Ling handed over a cup of tea: "Please sit down first and continue chatting."

"Mr. Qin's time is precious. I'm afraid that it will delay his work. Anyway, this is the main reason why I came here." Sun Xuewen looked at Zhao Ling: "Mr. Zhao, I heard that you will help Mingzhou Group in the future. Mr. Qin has

As a good wife, your career will develop faster in the future."

"Why are you delaying work? We don't have much work to do. Let's have dinner together before leaving." Qin Tao said.

"Yes, Director Sun, we will definitely be in contact with each other frequently in the future. We will eat together and become familiar with each other." Zhao Ling also spoke.

Unable to resist this enthusiasm, Sun Xuewen stayed. However, he was not the only guest at the dinner table, Mr. Ben also came to join in the fun.

The bidding units and suppliers sat together to eat and drink together. What happened on the day before the bidding was astonishing. If it were in other industries, the bidding units would be sworn enemies, and I don't know what tricks they were playing in private.

However, in the shipbuilding industry, this kind of scene is not unusual. After all, Mingzhou Group is already a leading enterprise in the shipbuilding industry. Domestic shipyards of all sizes have cooperative relationships with Mingzhou Group. With Mingzhou Group

They are all enjoying the market share gained by the constantly collapsing foreign shipyards.

"Lao Ben, I heard that the cost of the four-sided phased array radar has come down again?" Sun Xuewen asked.

"Yes, one phased array radar used to cost 100 million. Now, our technology has gradually matured and the scrap rate has been greatly reduced. Now we can make a four-sided phased array radar, which is about 100 million." Mr. Ben said: "However,

It is still very expensive, and the target set by the Navy is to drop it by half, and if it costs 50 million, we have to cover all four sides. We can still do it if we work hard."

"Fifty million, it seems that the Navy has completely disdained us." Sun Xuewen said: "I guess this is the only one of our 052Bs."

"This is not necessarily true." Qin Tao said: "If this bidding fails, you can also push this destroyer to the international market. The Navy will definitely not let our 052C be exported. Yours will be much easier. Even if it is

It is considered low-end domestically, but internationally it is much better than those European warships, so there must be a market for it."

"When the time comes, I'll have to trouble Mr. Qin." Sun Xuewen raised his glass: "Come on, I'll do it first as a token of respect."

"By the way, Mr. Ben, our phased array radar technology must continue to be developed. The one currently used is air-cooled, which is considered mature. Next, we must work on liquid-cooled ones. From now on, our four-sided shields must be

Just be flat."

When the radar is working, it emits a lot of heat. If the heat is not taken away, the radar will soon become overheated and unable to work.

Domestic phased array radars first use air cooling, which blows cold air to take away the heat. This design is very simple and works very stably, but it has one biggest problem: damage resistance on the battlefield.

Once shrapnel hits the radome and leaves a big hole, it will destroy the air flow inside. Even if the radar array is not damaged, it will soon overheat and fail to work properly.

The disadvantage of liquid cooling is complexity, because the liquid cooling pipeline needs to be deployed behind the T/R component, which greatly increases the complexity of the system. When the production of T/R components was initially unstable, liquid cooling was considered.

It's meaningless, but now, we can start.

"Of course, we have already started to develop liquid-cooled components. After all, the radar prepared for your J-31A is going to be liquid-cooled in order to have better performance."

The air-cooled phased array is the first of its kind in China. In foreign countries, for example, the phased array radar used on the F-22 fighter jet is liquid-cooled. Airborne radars have been liquid-cooled for a long time, so now, they

It also plans to develop a liquid-cooled phased array airborne radar for the J-31A.
