Chapter 523: You cant have your cake and eat it too
It was Qin Tao who firmly supported the 14th Institute in the beginning, and in recent years, the research and development of the 14th Institute has also been carried out at a rapid pace.
"Currently, through our efforts, we have reduced the length of each T/R component by 5 centimeters, so that the number of such components will further increase under the same size. After target shooting tests at sea, we found that C-band radar
The performance of the C-band response antenna is not enough, so we expanded the area of the C-band response antenna from the original 0.3 square meters to 0.8 square meters, which is an expansion of 2.5 times. In this way, even if the target’s echo is very weak, we can calmly guide it to the missile, and successfully
solved the problem."
"As for its weight, after our efforts, the aluminum alloy frame now weighs 1.25 tons. With all the components included, the weight is only 3.5 tons, which is even lighter than the pre-planned 4 tons."
Xing Wenge looked at the manuscript and introduced everything.
The navy is currently bidding for an air defense destroyer, so the main introduction is to the air defense system. After these introductions are completed, the unit responsible for providing the ship's power system will also come up.
"At present, we have completed all the test runs of the GT-gas turbine. It is running smoothly without any accidents and is fully qualified for shipment." Wen Xueyou also came up and gave a brief introduction: "We are currently undergoing its modification.
, that is, the development of GT-gas turbine, the power will be greatly improved and the fuel consumption will be reduced.”
Just like the turbofan 15, the current domestic power system research and development is taking the safest path. We will not consider any improvements first, but first understand the original technology, even if it is backward.
Therefore, what we are currently working on is a low-power version of GT-, and even this kind of thing can already meet the needs.
Two engines can drive a 6,000-ton warship perfectly. If it is a GT-, two engines can drive a 7,000-8,000-ton warship without any problems.
"Now, we have all the technical reserves, so next, let's ask the technical team to make an introduction. Mr. Qin, do you want to come first?" asked the leader above.
Qin Tao nodded: "Okay, let's go first. Yang Gong, please introduce us to everyone."
Yang Dawei stood up, walked up with his notebook, and connected it to the projection screen.
The other people's introductions were all straightforward, without even a PPT. As soon as Yang Dawei came up, he started to use high-tech equipment.
Mingzhou Group is a trench!
Then, a warship with an elegant and smooth shape appeared on the projection screen.
Beautiful, so beautiful!
The entire warship has a stealth design, and the upper layer of the hull is recycled inward. Like the No. 666 frigate built by Mingzhou Group, it is much more majestic than other warships.
The four shields are placed at the four corners of the bridge. They are different from the front, rear, and right layout of the American Aegis ship. Instead, they are rotated forty-five degrees, namely left front, right front, left rear, and right rear. Each shield controls nine
With ten degrees of airspace, the layout seems more appropriate.
The bridge is far away from the ship's guns. This is because six eight-unit anti-aircraft missile launchers are arranged in this part of the front, so there are forty-eight anti-aircraft missiles.
Although Qin Tao has proposed some hot and cold co-rack launch methods, these require research and experimentation, so the most common runner launch method is still used, which is very similar to the layout of 054.
All anti-aircraft missiles are arranged in the front, and there are still many buildings in the back.
The ball above the bridge is the guidance radar for anti-ship missiles. There is also a ball on the top of the mast, which is responsible for the warning task.
Behind the bridge are the air intake and exhaust ports. The exhaust port is changed to a round shape and has a heat dissipation window on the outside, which looks a bit unique.
Behind is the anti-ship missile launcher, and behind it is the helicopter hangar.
Above the hangar, there is a meter-wave antenna device, and there are 730 close-in defense guns on both sides.
Overall, the layout is reasonable and very smooth. It is Mingzhou Group's mastery of warships over the years.
Facing this picture, Yang Dawei began to introduce it.
From the single-barreled 130mm naval gun at the front, to the four-sided phased array radar on the bridge, to the back, we talked for a full two hours, and many details were clearly introduced.
Along with his introduction, pictures were constantly being shown, showing the results of their work.
By the time Yang Dawei finished his introduction, it was already noon.
"Everyone, should we go to the cafeteria to have a meal first, and we can start other bidding plans in the afternoon?" said the leader who presided over the meeting.
People are like iron, and food is like steel. If you don’t eat one meal, you will feel hungry!
Everyone stood up and headed to the restaurant.
Sun Xuewen came over again.
"Mr. Qin, your design is so beautiful!"
"Mr. Sun, you have been following me like this, and a word flashed in my mind involuntarily." Qin Tao said.
"What word?"
"The weasel is wishing the chicken a happy new year." Qin Tao said: "We are bidding rivals! Do you have any ulterior motives in following me like this?"
Sun Xuewen smiled awkwardly on his face: "Mr. Qin, I want to let you know that our Bincheng Shipyard is sincere. Regardless of the outcome of the bidding this time, it will not affect our friendship."
"Of course." Qin Tao nodded: "Are you afraid that once you succeed in bidding, our Mingzhou Group will cause trouble for you in terms of civilian ships?"
Sun Xuewen was even more embarrassed, that's what he really meant.
If the bidding is successful, Mr. Qin will be very angry. As long as they are not provided with Yinwa steel, the natural gas ships under construction at Bincheng Shipyard will have big problems!
Once the delivery time is delayed or even unable to be delivered, the compensation will be astronomical, and their Bincheng Shipyard will collapse!
That's why he kept coming to please Qin Tao.
"I'm very angry." Qin Tao was a little annoyed: "In your eyes, this is what our Mingzhou Group is like? I, Qin Tao, am just a coward? If I really want to do something, I can bring domestic
All the shipyards went bankrupt, and then they were merged, do you believe it?"
This chapter is not over yet, please click on the next page to continue reading! "Believe it, I believe it." Sun Xuewen nodded quickly.
"But, I didn't do that. We want to become bigger and stronger and compete in the world. It would be too shameful to fight among ourselves." Qin Tao said: "You should also see that our Mingzhou Group is not only Chinese, but also
It belongs to the world, and we are developing all over the world. How can we be interested in the three melons and two dates in China?"
"Yes, yes, Mr. Qin, I judge a gentleman with a villain's heart." Sun Xuewen blushed.
"Mr. Sun, don't worry. Even if we lose this time, we will continue to cooperate amicably with civilian ships. The profits lost on warships will be made up from civilian ships." Qin Tao said with a smile: "Moreover,
If you succeed, you will save others from gossiping about us operating in secret."
Sweat broke out on Sun Xuewen's forehead, and there was shame in his eyes: "Mr. Qin, our level is one level behind yours! We are indeed still looking at the country, and you are already looking at the international level. I wish to
You promise, we will work hard to win the bid and beat you on the anti-aircraft destroyer!"
"That's right." Qin Tao said with approval: "Beat us, only then can you gain the respect of me, Qin Tao!"
"Yes." Sun Xuewen was deeply moved.
Mr. Qin is very powerful. If there is any trick, there is no problem with this bidding. However, Mr. Qin did not do this. Mr. Qin attaches great importance to the domestic air defense destroyer project, but Mr. Qin attaches even more importance to the development of domestic shipbuilding enterprises!
This is a noble person, a moral person, and a person who has escaped from vulgar taste!
If Qin Tao knew at this time that Sun Xuewen was putting his own evaluation of his father on himself, he would definitely not be in a good mood.
Sun Xuewen's heart was filled with warmth.
The other people are also very funny. I don't know what Qin Tao and Sun Xuewen are talking about. Looking at their expressions, I can guess something.
Mr. Qin is awesome!
We are obviously competitors, but we can face them with this kind of attitude, competing and cooperating at the same time. It is so rare.
After dinner, in the afternoon, it was the turn of bidding for the Bincheng Shipyard.
"Dear leaders, hello everyone, our shipyard lacks design capabilities, so our warship design is entrusted to a domestic ship design institute. An important design idea for the entire warship is to save money as much as possible.
to get the strongest performance.”
Save money!
This of course refers to those 500 million.
Although domestic design institutes also use computer-aided design, when Sun Xuewen reported, he did not use a high-end notebook to make a PPT. He used ordinary design drawings.
The Ship Design Institute specially made an extra-large wall chart and hung it directly on the projection screen. The colors of this wall chart are more gorgeous and it looks very beautiful.
When Qin Tao looked over, his heart suddenly felt excited, and a number jumped into his mind.
054B!
If you don't compare the size, it is almost the same as 054B in my original time and space!
The need for stealth is also taken into consideration as a whole. The upper building is retracted inward. Above the bridge in front, the mast is also made into a polyhedral shape. Four small shields are erected on the sides of the mast, which should be specialized C-band target illumination radars.
On the hangar at the rear, a rotatable shield was erected, which was a specialized long-range warning radar.
In the past, Qin Tao once heard Wu Shengli talk about this design concept. At that time, he felt that it was somewhat similar to the West. Europeans built this reduced version because active phased array radars were too expensive and could not be used.
warships, and domestic technology is becoming more and more mature, and the cost of active phased array radars is getting lower and lower, so a large number of Aegis warships with four-sided phased arrays have been launched.
But now, seeing this rendering, Qin Tao thought of 054B.
In later generations, the tonnage of warships became larger and larger.
The 054 is less than 4,000 tons, and by the 054A, it has exceeded 4,000 tons, which is larger than the displacement of the famous China's first ship.
When it developed to 054A, it seemed to have matured. However, technology continued to develop and the needs of the military continued to increase, so 054B finally came into being.
Of course, the focus of later generations is not on its rotating phased array radar, but mainly on its propulsion system.
The displacement of this frigate has been enlarged to five to six thousand tons, and four diesel engines are no longer powerful. Therefore, it uses a new generation of high-power gas turbines and a combination of two diesel engines.
Moreover, it uses the most advanced comprehensive electric propulsion system. In this way, there is no need to worry about whether it is diesel-fuel alternating or diesel-fuel cross-linking. When it is necessary to sail at high speed, all the main engines are started at the same time. Anyway, they all drive the generator.
All the electricity is integrated together, and that's enough.
Now, you don’t need to pay attention to the power system. This is nothing more than alternating diesel and combustion, using the diesel engine at low speed and the gas turbine at high speed. It is impossible to parallel the cars together.
Of course what everyone is paying attention to is the air defense system.
"Currently, we want to build a new type of destroyer, but the most important problem is that it is expensive. Therefore, we have chosen a single-sided S-band phased array radar as the main radar. It scans the surrounding sea and air by rotating. In this way,
By simplifying four sides into one, the cost can be reduced from the original 500 million yuan to more than 100 million yuan." Sun Xuewen's explanation became more and more relaxed: "I think if we can get the bid today, then we can beat Mingzhou.
What the group has is not technology, but money in our pockets.”
The crowd burst into laughter.
Qin Tao also laughed along with him.
If it weren't for the conversation at noon, Sun Xuewen would never be so relaxed. He would definitely be worried about these things, but now, he finally doesn't have to worry!
He could be generous and even joking. When he said this, he glanced at Qin Tao and saw that Qin Tao was also smiling, and he felt relaxed for a while.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! No matter who wins the bid, it is for the development of our navy. The paths are different, but the purpose is the same.
We all come from all over the world, and come together for the same goal! Before he knew it, Sun Xuewen had this sentence in his mind. It seemed that he had returned to the passionate era. Many things had changed, but there were also some
Things haven't changed.
"Because of the way it rotates, we changed the shape of the phased array radar antenna. It used to be a rectangle of four meters by four meters, but now it is a rectangle of three meters by five meters. This reduces the height and makes it easier to rotate.
Easy. Since the C-band antenna is removed, the overall number of T/R units is still about the same. The search distance can be maintained at 300 kilometers, meeting our long-range air defense needs."
"Are our 14th branch conducting research in this area?" a leader asked.
The 346 Sea Star radar of the 14th institute has always been based on a four-sided phased array as the core, and does not use this kind of rotation.
After hearing the question, Mr. Ben spoke: "We have not conducted research in this area, but our previous radars were all rotating, so there is no problem in the data processing of rotating radars. The shape of the phased array radar antenna changes.
, it won’t cause any problems. The only problem is that with this method, the refresh of the target is definitely not as good as the four-sided phased array.”
There are advantages and disadvantages. This can reduce costs, but like other radars, it scans a circle and can continue to scan the target for the second time after returning. It is completely different from the original four-sided shield staring at a certain sky.
This means you can't have your cake and eat it too. If you want to save costs, you have to endure the problem of slow data refresh.
"Old Sun, let's continue talking." the host said.
"In terms of target illumination, we use four small C-band radars." Sun Xuewen continued: "In this way, after discovering enemy missiles or aircraft incoming attacks, we still have multi-directional anti-saturation interception capabilities. If
If leaders can increase the budget, the area of these four small shields can be expanded and a detection range of 100 kilometers can be achieved. It would be more appropriate if Red Flag Nine could use active guidance."
What the navy lacks most is regional air defense capabilities. In the past, it was unthinkable that it would be able to do multiple-choice questions!
There are two options, one with comprehensive performance and one with affordable price. Which one will the Navy choose?
At this time, even Qin Tao became a little curious.
Mingzhou Group has been preparing for this for a long time, so of course it hopes to obtain orders from the Navy. However, Mingzhou Group has no shortage of orders on hand. Even if it does not have this warship construction contract, it will be insignificant.
Moreover, it was an honor to lose, not because it was not advanced enough, but because the cost was high, and the high cost had nothing to do with the Mingzhou Group, it was the fault of the 14th Institute.
Thinking of this, Qin Tao has begun to look at this bidding with a lively mentality.
Sure enough, after the introduction of Bincheng Shipyard was completed, the meeting entered a stage of intense discussion.
"The Bincheng Shipyard's plan is in line with our current situation. We can use a small number of underground air defense destroyers to completely solve our air defense problem with less military expenditure." A leader spoke.
"No, I firmly object!" One person raised his hand: "Our aircraft carrier formation cannot be lame. In order to fully provide regional air defense capabilities, we must have warships with four-sided phased array radars!"
Qin Tao became more and more interested.
The person who objected was Li Yan.
As the first captain of the aircraft carrier, Li Yan stole the show during the last exercise. However, after the exercise, the aircraft carrier had to continue to be renovated, so Li Yan had to return to land and continue training in the wasteland village.
This time there will be a meeting to decide on the construction of the Navy's most important air defense destroyer in the future. Li Yan, the aircraft carrier captain, is also qualified to participate.
As a captain, he knows very well that two swords are not enough. He must have a qualified regional air defense destroyer, so that he can deal with future maritime threats!
"The plan proposed by Bincheng Shipyard is in line with our current situation.
There is no essential difference between the 051Cs. In our last aircraft carrier formation, the two 051Cs were specially guarding our tail because these two warships did not have omnidirectional air defense capabilities. Now, the plan of Bincheng Shipyard
, will inevitably leave some scanning blind spots in front of the warship. On the battlefield, once the enemy flies from directly in front of the warship, it will inevitably not be detected in time."
The two masts at the front and rear must be higher and lower. They take care of the C-band radars on all sides, but they cannot take care of the long-range scanning radar at the tail.
Only the Mingzhou Group's solution will not leave any blank areas for scanning, and there will be no chance of any fish slipping through the net accidentally.
"Although in formation operations, we can reduce blind spots through mutual cooperation, we are not that rich yet. Many times we have to go out to fight alone. We need warships with four-sided phased array radar. If it is too expensive,
And if the construction quantity is small, I would rather use 054 to supplement it!"
The front-line commander of the Navy gave this answer: Warships that firmly require four-sided phased array radar! They are users, and of course they have to consider themselves. They don’t care about money.
The last time the aircraft carrier formation went out, it was assembled by mobilizing the main forces of the three major fleets. Of course, we cannot do this in the future.
Look at the American aircraft carriers. When they go out, there must be at least two Ticonderoga-class ships next to them! We must also have at least two warships with four-sided phased array radars, so that we can feel at ease!
"However, our strength is limited. The number is too small to meet the needs of the navy. We currently have to build more warships within limited funds!"
The superior leaders have no choice but to consider everything.
If the navy wants to go to the ocean, it must have a numerical advantage. It is time for the outdated 051 to be updated!
The 052 destroyer will become the main force in the future, and the number must be high!
Besides, as long as you don’t compare with the United States, look at other countries in the world. Which one has such a warship?
Well, that is to say, the island country has just launched its second Kongang-class destroyer, which uses the American Aegis system. There is no trace of it in Europe yet. Don't they have any demand for air defense ships?
"Cough, cough." Wu Shengli, who had been silent until now, finally spoke.
"Everyone, I have a proposal." Wu Shengli's words immediately attracted everyone's attention, and everyone looked at him.
"One is quality and the other is cost. We can't have it both ways." Wu Shengli said, "Should we each build one to determine which one is more suitable for us?"
Everyone's eyes lit up.
Here, it is purely about talking on paper. First, each build an experimental warship. After it is built, they conduct a lot of tests to finally determine which one is better, and then build it in large quantities.
You can't rush this kind of thing anyway.
"I think it's okay." The leader presiding over the meeting said, "Let's vote by a show of hands now."
With a roar, most people raised their hands, and the democratic vote was passed.
"Okay, let's start construction on two models at the same time. The Bincheng Shipyard's plan is named 052B, and the Mingzhou Group's plan is named 052C!" The leader who presided over the meeting made the decision.
This has never happened before. Every time Mingzhou Group participates in the bidding, it almost succeeds with an absolute advantage. But now, the superiors are actually faced with difficulty in choosing, and they have to start construction on two ships at the same time!
Everyone looked at Qin Tao.
"We accept the navy's arrangement." Qin Tao said, "However, the navy has to order two sets of four-sided phased array radar Haizhixing systems at one time."
Two sets?
Two sets is one billion!
Everyone is very surprised. The Navy has given you an order for one ship. How can you ask for two sets? Do you still want to use it as a backup?
"Our aircraft carrier is still waiting." Qin Tao said this, and everyone suddenly realized.
Even if the Navy chooses the Bincheng Shipyard plan, the Mingzhou Group will not lose.
Damn, it has to be installed on that aircraft carrier!
