As fast as lightning and as steady as a dog, the advantages of trimaran are obvious, but the disadvantages are also obvious. The volume of the same displacement is not large enough, so it is not suitable for ocean navigation. Moreover, the operation of trimaran will be better than that of traditional monohull. It’s complicated. There is always a reason why trimaran has not become mainstream for so many years.
Now, after hearing such an analysis, everyone calmed down and could not lose their minds because of the advantages of the trimaran. Therefore, they chose the layout of the trimaran. They needed to consider it comprehensively to see what kind of structure should be needed.
“Next, let’s listen to Mingzhou Group’s design plan.” Wu Shengli said.
Just now, after listening to the plans of his brother units, Yang Dawei was a little embarrassed to come up with his own plans. Over the years, every project has been his own. As time goes by and the number of times increases, has he lost his creativity? , only know step by step? This plan from our brother unit is obviously better.
But after hearing Qin Tao's analysis, Yang Dawei finally understood that the plan of his brother's unit was not the best. It turned out to be flawed. Mr. Qin did not choose the trimaran layout, not because Mr. Qin no longer had it. Innovative capabilities, but because this trimaran is not suitable.
Confidence finally returned to his body. He picked up his notebook, walked to the front, and connected it to the projection screen.
“Everyone, let me introduce to you our 054B plan, which is a conventional warship with a displacement of 6,000 tons...”
There is nothing eye-catching about this project, it is quite satisfactory.
The warship has a total length of about 147 meters and a total width of about 18 meters. However, when seeing the design drawings, everyone’s attention was still attracted by the double-sided back-to-back rotating radar on the top.
The top-plate radar is two radar plates, back-to-back. The two are not parallel, but staggered at an angle. It looks like two folders that are not neatly placed. The British radar is also very simple and plain, with the top plate It's almost the same, except that it has a ball on the outside, which makes it look a bit taller.
The radar in front of you is much more beautiful. It is placed at an angle, and a tetrahedron protrudes from the side, forming a whole with the mast below. It not only takes care of the stealth, but also is very smooth. Moreover, the size is not small at first glance. .
“After coordinating with the 14th Institute, we decided to increase the screen size of this phased array radar to 3.5 meters, which can accommodate enough T/R components and have a maximum search range of 300 kilometers.”
This flat panel is definitely not small. You must know that the Yankees' Aegis radar is only 3.7 meters in size, and it is also octagonal. The surface of our radar is quadrilateral, and its overall performance is definitely better than Aegis!
"Due to the high location, it is easier to detect ultra-low-altitude flying targets. Due to the use of a phased array radar system, the search efficiency will also be improved. Specifically, against anti-ship missiles such as Harpoon, we can It can be captured at a distance of 65 kilometers. To deal with cruise missiles with stealth capabilities, they are also sure to be captured within 40 kilometers. The ship-borne Hongqi-16 air defense missile has the ability to intercept twice. If these two times have not been If you intercept it, hand it over to our 1130 and close-in defense artillery."
Everyone started to study it seriously.
There are more and more domestically produced shield ships, but due to various reasons, the installation position of the phased array radar is not high, so the ability to deal with ultra-low-altitude sea-skimming targets is not strong. In order to make up for this flaw, it is installed on the top of the mast of the ship's bridge. A special sea search radar has been added to make up for the blindness, and with this modified 054B, this defect can be supplemented.
054B holds a tall rotating double-sided phased array radar, which can make the fleet's air defense system more complete!
“Yes, this can just make up for the shortcomings of our fleet, and the fleet’s air defense will be more complete!” A leader nodded.
“The front launcher is still 32, but after consultation with relevant units, we determined that the size of the launcher can fully meet the needs of the Hongqi-16F under development. The maximum range of this missile has reached 160 kilometers.”
160 kilometers! When this data came out, everyone was shocked.
At the time when the HQ-9 was launched, it only had a range of 80 to 90 kilometers. It was already considered very impressive and could provide a regional air defense protection network for the navy. But now, the latest HQ-16 has a range of 160 kilometers! The 054B equipped with this kind of missile has also evolved into a regional air defense ship!
Back then, Qin Tao obtained the Shikili anti-aircraft missile from Lao Maozi. Through domestic mapping and imitation, he developed the ship-based Hongqi-16 anti-aircraft missile. Although the range was only more than 20 kilometers, it already made the navy very excited. It is much better than the Hongqi 61 that I have been working on alone for decades, and it is also more advanced than the imported Sea Rattlesnake!
After the basic model was successfully developed, relevant units began to develop an upgraded model. The Hongqi-16A added a relay guidance system, allowing it to fly on a more fuel-saving high-throw ballistic trajectory. The range was expanded from 25 kilometers to 40 kilometers, becoming a A reliable medium-range air defense missile.
However, relevant units are not satisfied yet. If they want to continue to increase the range, they must rely on advanced solid rocket motors to increase the range. This is the Hongqi-16B/C missile. The two models are roughly the same, except that one is used by the Army and the other It is used by the navy and its range has been extended to 70 kilometers.
The increase in range means that the guidance system must also be improved. This missile has already adopted strapdown inertial navigation, mid-course command correction, and terminal main/semi-active radar guidance system. With the advancement of Oriental electronic technology, these are nothing. .
I originally thought that this kind of missile had been fully developed, but the relevant units gave me another surprise. The range was further increased to 160 kilometers!
“How is it possible to achieve such a large range? Has the projectile been lengthened again?”
When it was originally improved to the Hongqi 16-B/C, a new engine was installed and the length of the missile was increased. From the appearance, the position of the missile's side strips has changed, which is actually caused by the lengthening of the engine.
Now that the range has doubled, the size must also change, right?
"The size has not changed much." Yang Dawei introduced: "This missile is actually compatible with the original air defense system. Its range increase is mainly achieved by changes in appearance. Like Hongqi-9, it has become A polished rod bullet.”
An important indicator related to missile range is air resistance. The normal flight range of the Phoenix missile is only 30 to 40 kilometers, but if it flies to an altitude of 30,000 meters first, the range can be increased to 120 kilometers.
For the same missile, everything else remains unchanged. The smaller the resistance, the farther the range.
The Hongqi-16 has a lot to do with Shikili. It uses a layout of four side wings and tail fins on the missile body. The side wings can provide a certain amount of lift to the missile and can also serve as reinforcements. In many cases Anti-aircraft missiles are equipped with them, but the side wings also bring flight resistance.
When the speed of the missile increases to a certain level, the missile body itself can generate enough lift. At this time, the side wings are useless. This is the case for the Hongqi-16F, which canceled the side wings and became a bare rod missile. The air resistance is reduced, and the range will naturally increase.
“Bare rod ammunition? Isn’t it the same as our Hongqi-9? By the way, does it have a tail fin?”
The edge strip in the center of the missile body can be removed, but the tail fin must be retained. After all, this is the main means of controlling the trajectory of the missile.
“It has a tail fin and a side thrust system, which can increase the mobility of the missile and facilitate interception of more mobile targets.” Yang Dawei said.
If it only has a long range, of course it cannot be called an advanced missile. The maximum maneuvering overload of the Hongqi-16F can reach 35G. This is the best. It not only has aerodynamic rudders, but also has a special side-injection engine that can directly generate The lateral force greatly increases the mobility of the missile, which is enough to intercept highly maneuverable targets. The F-22 can kill with one hit even when it comes!
“Our Hongqi-16 has made rapid progress and has surpassed the basic Hongqi-9. By the way, how far has the Hongqi-9 developed?”
“The combat slant range is 260 kilometers, and the maximum range is 400 kilometers.” Yang Dawei said: “The new Hongqi-9 missile currently under development can already reach this level, and it must be better than the Hongqi-16.”
The maximum range of the missile is just for bragging and has no practical significance. However, the maximum combat range of 260 kilometers is meaningful, which means that it can intercept the target at a distance of 260 kilometers. Even to be on the safe side, it can intercept the target at a distance of 200 kilometers. , it’s still fine.
“At the same time, the Hongqi-9 missile also has the ability to intercept ballistic missiles with a range of less than 500 kilometers. We can easily intercept weapons like Scud.”
"Yes, our 055 is an 850mm crater. These anti-aircraft missiles can be mixed!" "Ahem, leaders, are we discussing the 054 project in this meeting?" Qin Tao reminded.
“That’s right, 054, let’s move on to 054!”
Yang Dawei continued to introduce the entire project from front to back, and all the leaders nodded frequently, especially the design of the internal cabin, which is spacious, has an activity room, a reading room, and a special room for female soldiers, all of which are There are bunk beds, a wardrobe, and a bathing area. Such conditions can make sailors more energetic at sea.
"If this is the case, the demand for fresh water on the warship will probably be very large." A leader looked at the large bathroom and frowned. It was great to take a shower every day, but there is limited fresh water on the warship!
"This problem is no longer a problem. Our domestic relevant units have developed mature reverse osmosis seawater desalination devices. They can not only be used on aircraft carriers, but improved models can also be used on destroyers and frigates. In the future, drinking water on our warships Fresh water needs to be replenished specially, but other domestic water can be replenished using reverse osmosis." Qin Tao said.
How to solve the problem of drinking water during ocean sailing?
In the beginning, we had to carry water with us, and we strictly controlled the standards. Each person was given one or two liters of water a day, which was enough to wash your face and brush your teeth. Anyway, you went out for a few walks and then went back. Later, there were supply ships, and in the ocean Fresh water can be replenished on the water so that warships can sail long distances.
However, it is better to rely on supplies than to rely on yourself. There is seawater all around. As long as the seawater is desalinated, it can be used.
The first desalination device used was distillation equipment, which has developed into three methods: steam distillation, waste heat distillation and water vapor compression distillation. Although the methods are different, the principles are the same, that is, seawater needs to be evaporated and then condensed. Things like salt stay, and fresh water goes out.
This method is very simple, you can even use a kettle to do it, but this thing consumes energy. Even if you use the waste heat of the engine, it still requires energy, and it consumes a lot.
In comparison, the reverse osmosis method is much simpler, the energy consumption is only one-fortieth of the distillation method, and it can be produced in large quantities.
Under normal circumstances, the salt in seawater will penetrate into freshwater, or diffuse, and eventually reach a state of equilibrium. Reverse osmosis allows high-concentration seawater to flow into low-concentration water, just like in low-concentration water. The salt in turn enters the high concentration. The key here is a reverse osmosis membrane, which pressurizes the seawater on the high concentration side, allowing water molecules to pass through, leaving the salt and other things behind.
Later generations of water dispensers also used this method, except that only one layer was used in the water dispenser. If you want to desalinate seawater, at least three layers of equipment are needed.
If the performance of the reverse osmosis membrane is good enough, the fresh water produced by the third reverse osmosis method may be better than the distillation method and can fully meet drinking standards. However, to be on the safe side, you can use fresh water from the land for drinking water and a reverse osmosis device for other domestic water. Prepared fresh water.
In case the reverse osmosis device breaks down, it can still meet the most basic survival needs. If you rely entirely on this, there will be problems.
054B is completely prepared for ocean voyages. It has comfortable living conditions, sufficient fresh water supply, and is very considerate in all aspects. These are things that trimaran cannot provide at all. Even if the project is expanded to the same 6,000 tons, There won't be such a spacious space.
Of course, the helicopter landing platform is really big, but what’s the use? This is a frigate, not an aircraft carrier.
After the two project reports were completed, the naval leaders exchanged opinions.
“We all agree that in order to go to the ocean and have a more comfortable environment, Mingzhou Group’s plan is more suitable for the needs of the navy.” Wu Shengli said: “In this bidding, Mingzhou Group won!”
Facing challenges again and again, Mingzhou Group has maintained a record of complete victory. Yang Zhenjun was not discouraged even after the failure. Failure is normal in this kind of thing, and success is a super-level performance. As long as they dare to bid, they will win. It’s already pretty awesome.
Looking at other domestic shipyards, they don’t dare to challenge Mingzhou Group. We are proud of our defeat!
“Everyone, I have another suggestion.” Seeing that the meeting was about to end, Qin Tao spoke quickly.
"explain."
“There is still a lot to like about the design of the trimaran of the brother unit. I suggest that the navy can order one.”
As soon as these words came out, many people opened their eyes wide.
They all say that Mr. Qin is interesting, and indeed, even if we fail, Mr. Qin will find us something to eat!
In the past, those manufacturers who failed in bidding were not treated badly and had projects. Now their 718 Institute is no exception. Even if they fail, Mr. Qin will give them an order.
Wu Shengli shook his head: "Since we have chosen your Mingzhou Group's project, of course we will not build another alternative trimaran. The navy will not purchase two different types of warships at the same time. This will not be convenient for logistics and maintenance. It is inconvenient for naval operations.”
"I'm not talking about a formal warship, but a training ship. The navy is in the stage of large-scale expansion and has a huge demand for sailors. The existing training ships at the Naval Academy are not enough. It is necessary to purchase such a trimaran. The ship can test whether the trimaran is suitable for the needs of the navy, and it can also train students, killing two birds with one stone." Qin Tao continued to help promote it.
Although we have not developed one, the trimaran is a warship with many advantages after all. You can build a small one first, and only after trying it can you know whether it is suitable. If it is suitable, you may be able to build it in large quantities in the future.
Wu Shengli rolled his eyes at Qin Tao: "There is a shortage of warships to train students. However, our navy's equipment is constantly updated. It is enough for us to retire a few warships and hand them over to the Naval Academy. Why build new ones? Do you think the navy's money comes from strong winds? of?"
The navy is constantly expanding its strength. Brand-new warships are being produced and old warships are being retired and eliminated.
What are they going to do if they are eliminated?
Some are given to the Coast Guard, some are given to museums, some are dismantled, and some can be given to the Naval Academy!
"What can we do with old warships? They can no longer adapt to the development of the times. We need brand new warships with advanced computer systems. This is like training train drivers, using steam engines for training, and finally getting started with high-speed rail. This OK?"
“A steam locomotive is better than a simulator.” Wu Shengli said: “You are so supportive, so why don’t you pay them to build one? You are so capable, you sell the trimaran!”
Yang Zhenjun looked at Qin Tao with some gratitude: "Mr. Qin, thank you for your support, but let's forget it. If the Navy doesn't pay, we won't build it. Being able to attend this meeting can give the leaders of the Navy a We are very satisfied with building new ship types.”
Qin Tao shook his head: "No, I think Leader Wu is right. We can sell the trimaran!"
If it is not suitable for personal use, then export it!
In the past, if it was not used by oneself, it would never be exported, but in recent years, Dongfang's shipbuilding technology has developed rapidly, and Dongfang's warships have been equipped in many countries! The ships promoted by the East are very popular in the market.
A trimaran is such a tall ship that can be used as an aircraft carrier, so there will definitely be buyers who like it!
“Sell it out?” Yang Zhenjun and others’ eyes flashed with golden light.
“That’s right, let’s sell it. The Abu Dhabi International Defense Exhibition is about to be held. We can just go there for the exhibition. You hurry up and make a beautiful model.”
