"Currently, we are manufacturing this scaled prototype." Ma Ming led everyone to the front of the device, picked up a module with an inverted trapezoidal section and said: "The track of the prototype is composed of such modules.
Inside the groove, the ejection shuttle is installed, and the ejection shuttle is connected to the drawbar to drive the aircraft."
This track is just like a water channel. The inner surface is very smooth. After all, the ejection shuttle has to move inside. This ejection shuttle is actually equivalent to the mover of a linear motor with rollers.
Everyone's eyes turned to this module.
"Our domestic high-temperature superconducting technology has developed very well. Are high-temperature superconducting materials used in this track?"
"Yes, our domestic high-temperature superconducting technology is being developed rapidly. I am also very optimistic about this material. But so far, these materials are still in the laboratory. Therefore, in order to ensure reliability, we have not used high-temperature superconducting technology for the time being.
Superconductors still use ordinary silicon steel materials. In the future, after our high-temperature superconductors are used in engineering projects, we will definitely improve to this solution."
Superconductor is a special material. Ordinary wires have resistance. However, when certain materials are lowered to a certain temperature, the resistance will drop to zero. At this time, the current can flow without any obstruction.
By, this phenomenon is called superconductivity.
The emergence of superconductivity has aroused the favor of many people. If this technology can be used on a large scale, human science and technology will enter a new era. For example, there will be no losses on transmission lines. For example,
Create super electromagnets and more.
However, the application of superconductors is difficult because it only has properties at low temperatures. This phenomenon disappears when the temperature is slightly raised.
For several years, technical experts from various countries have been studying related materials and trying to increase this temperature. This is not a high temperature of hundreds or thousands of degrees, but several degrees below zero.
In 1987, it was successfully raised to minus 183 degrees. In 2015, it was raised to minus 70 degrees. This temperature is far lower than room temperature. Therefore, if you want to use these high-temperature superconducting materials, then
Corresponding refrigeration facilities need to be provided.
Therefore, for a long time, superconductors have stayed in the laboratory, and it is very difficult to use them in real engineering.
The electromagnetic catapults used by Americans also use ordinary silicon steel sheets as magnetic conductive materials. Of course, Ma Ming would not rashly choose immature things.
This module is wrapped with a large number of thick coils, which is a bit surprising.
"What we are currently making is only a scaled prototype, so the maximum current it allows can only reach 2,000 amps. When the scale model is used, this value will be increased to 20,000 amps."
Ma Ming's words shocked everyone again.
Twenty thousand amperes of current, what a terrifying number! However, only this powerful current can provide sufficient driving force.
"Then, its switch must be strong." Qin Tao said.
"Yes, it is impossible for us to energize all the modules at the same time. All the modules on the entire track are divided into eight parts. The corresponding parts will only be energized when the ejection shuttle passes by. In this way, we need to have eight reliable vacuum circuit breakers.
device."
No one has mentioned the difficulties of electromagnetic catapults. Even if they did, they would talk about the difficulties of energy storage devices, power supply, etc. In fact, just a switch is very demanding!
"Do we have this kind of technology?" Mr. Liu asked worriedly.
"Of course, we have advanced high-voltage power transmission technology, and we also have vacuum circuit breakers of this level. We sent our technical requirements to relevant domestic manufacturers, and within a few months, they provided us with fully qualified ones.
product."
When talking about this, Ma Ming was very proud. Related domestic companies have conducted a lot of research on these projects. Therefore, although the electromagnetic catapult sounds very high-end, in fact, there are also a lot of mature technologies that can be used.
.
Other countries do not have this advantage because they do not have the relevant technical reserves!
"If these eight circuits are all used for acceleration, can they be more effective than a steam catapult?" someone asked.
Looking at the progress of their own electromagnetic catapults, those who were initially skeptical have now begun to slowly change their attitudes, but they still have to ask questions.
"The acceleration provided by the steam catapult gradually decreases. After all, when the ejection is just launched, the steam pressure is sufficient. As the piston moves forward, the steam in the gas tank is continuously released, and the pressure will gradually decrease." Ma Ming said.
Get up: "So, when the pilot ejects and takes off, it will be very uncomfortable at the first moment, but it will get better later."
"This is not the case with our electromagnetic catapult. In our design, the acceleration will continue to be maintained at around 4G. For pilots who can withstand 9G overload, this acceleration is still bearable. During the entire process, it continues to accelerate, and ultimately
It reaches the take-off speed and is very smooth. In order to prevent our ejection shuttle from flying out, only seven circuits are accelerated. In the eighth circuit, the wheel will separate from the ejection shuttle, and then this circuit will brake the ejection shuttle.
, so that it can stop.”
In the laboratory, they can study acceleration technology first, and deceleration can rely on other means, but on the aircraft carrier, this thing must be able to stop, otherwise the ejection shuttle will go out together with the aircraft in one ejection.
The advantage of the electromagnetic catapult is that the acceleration is continuously maintained. However, when the Yankee's electromagnetic catapult ejected for the first time, the pilots were extremely uncomfortable because this acceleration was not continuous, but occurred each time it passed a module.
When accelerating once, a catapult has 288 linear motor modules, symmetrically distributed, which means that the pilot has to endure 144 short-term accelerations, which makes the pilot want to die.
This chapter is not over yet, please click on the next page to continue reading! Of course, that is because American pilots have adapted to steam catapults. After getting equipped with electromagnetic catapults, they began to feel uncomfortable. The aircraft carriers of the motherland are equipped with electromagnetic catapults.
, then the pilots will certainly not feel the same discomfort as American pilots.
Ma Ming continued to introduce various principles to everyone. From the beginning, they did not understand, but now, many people have intuitive impressions.
"So, how many years will it take for this kind of catapult to be developed?" Mr. Liu asked.
"We are only conducting scaled-down experiments now, and various problems may arise during this process." Ma Ming said: "A conservative estimate is that each experiment will take two years. After six years, our equipment will have
The ability to board the ship. Of course, if problems are encountered during the experiment, it may take more time."
This kind of thing cannot be said.
No one knows what obstacles are ahead. Once a problem occurs, it may delay their progress. They can only make conservative estimates. At the same time, they will do their best to develop and complete the project in the shortest possible time.
.
Six years!
At that time, the Oriental Sea Dacheng had just been renovated, and the first domestically produced aircraft carrier was also under review, so it would be ready to be carried on it!
"Okay, I hope you can work harder and complete the experiment of this catapult as soon as possible. I think this project can also apply for part of the funding from our army, and your company cannot bear all of it."
After hearing what Mr. Liu said, a leader on the scene spoke: "Mr. Liu, should our army use the limited funds to develop steam catapults as a backup? In this way, if the electromagnetic catapult fails, our own
Aircraft carriers also have steam catapults that can be used, but you can’t put all your eggs in one basket!”
Qin Tao glanced at the leader with some dissatisfaction. Isn't this too partial?
"Taozi, do you have any ideas?" Wu Shengli said: "After all, you have the most say in this project."
"Well, I have an idea." Qin Tao thought for a while and said: "Our electromagnetic catapult is undergoing a scale-down experiment. This experiment can verify many technologies. When the scale-down experiment is completed, it can be used with steam
Once the catapults are compared, the pros and cons will naturally be clearly seen. This way, there will be a competition, which will ultimately determine the ownership of the research and development funds."
"That's right, we need competition!" Mr. Liu nodded: "Only competition can give us more choices!"
Ma Ming's eyes were full of confidence. He was very confident. This system had too many advantages. The steam catapult was already a backward technology and there was no way it could compete with them!
"Mr. Liu, next, we will go to Mingzhou to inspect the two modern-class destroyers there." Wu Shengli said next to Mr. Liu.
Mr. Liu's main purpose this time is to see the aircraft carrier. However, to be on the safe side, the aircraft carrier cannot be seen until night. So what are you doing during the day?
First, I checked out the progress of the modification design in Huating, and also learned about the catapult technology. I still have half a day to go to Mingzhou to see the modern class!
In fact, the two modern-class ships purchased from Lao Maozi are not stationed in Mingzhou, but in Zhoushan.
However, Zhoushan and Mingzhou are only separated by dozens of kilometers. As long as the boiler is hot, the modern-class destroyer can move to the fleet base dock in Mingzhou at any time.
Although the displacement of domestically manufactured destroyers is getting larger and larger, so far, among the navy's main warships, the two modern-class ships with the largest displacement are still the ones purchased from Lao Maozi!
Mr. Liu's time is very precious, and the arrangements are very tight along the way.
Qin Tao followed Mr. Liu and also went to the naval base. After all, Qin Tao was also involved in the purchase of the two modern-class destroyers. However, when driving the modern-class destroyers back to China, Qin Tao was busy with the Kilo-class submarines, so he still
I have never seen these two warships, so I just happened to go along with them this time to join in the fun.
As for talking about electric cars with the horseman, we can only continue to put it off.
Anyway, the horseman is busy with the electromagnetic catapult and probably doesn't have time to study any electric vehicles.
It won’t be too late in a few years, as long as it is done earlier than Tesla. Moreover, in a few years, the battery will be more mature. By then, directly using this kind of battery pack will be much better than lead-acid batteries.
Anyway, just to make money, Golden Sun Motor Company will become Golden Sun Electric Vehicle Company in the future. Golden Sun brand electric vehicles are bright!
When we arrived at Mingzhou Military Port, it was already past four in the afternoon.
It is already the end of April, which is the best season of the year. The sea breeze is blowing, making it warm and humid.
On the pier, two large battleships stood there. Compared with the frigates docked next to them, their huge size could be seen.
"These two warships, which we named No. 136 and No. 137 respectively, are currently the main warships of our Eastern Fleet. They not only have large displacements, but more importantly, they have strong combat capabilities, especially the supersonic anti-ship missiles on both sides of them.
, is currently the most powerful among naval equipment, and is called the aircraft carrier killer by our domestic media." The fleet leader greeted the crowd and introduced it at the same time.
Qin Tao had a smile on his face. This leader was really strict enough. He was called an aircraft carrier killer by the media, not what they thought, because everyone knew that this thing was still far away from being an aircraft carrier killer.
However, it must be publicized in this way among the people, so as to increase people's love for national defense.
Ordinary domestic warships and anti-ship missiles are arranged near the chimney. When launching, they are launched directly to the side. Even if it is the 051, the triple launch box is forward, when it is actually launched, it must be launched.
The launch box rotates to the side.
The modern class is different. Anti-ship missiles are arranged on both sides of the bridge and pointed directly forward. This launch method allows it to directly aim in the direction of the enemy and launch missiles without turning the rudder when facing the enemy.
Lao Maozi likes to arrange it like this. Whether it is the modern class or the glorious class, it is always arranged on both sides like this. It looks majestic, but this also brings many problems.
"The layout of anti-ship missiles like Lao Maozi is still domineering." A leader said: "This kind of destroyer is just like a missile boat. It can charge forward bravely and launch missiles during the charge. Only the navy of the Red Empire can
With this kind of aggressiveness, we also need to have this kind of spirit.”
A smile appeared on Qin Tao's face.
"What, Tao Zi, do you have any objection to what I said?" the leader asked Qin Tao.
Qin Tao shook his head: "Of course I have no objection. Since our navy introduced this kind of warship, it has not fired live ammunition. When we have a live ammunition target practice next year, everyone will be able to see that spectacular scene, which will shock the heavens and weep the ghosts and gods!"
"
"You kid, if you have anything to say, just say it. Don't tell anyone else. Lao Zhao is not a petty person. Just say it openly. Lao Zhao won't blame you. If you hide even a few words, he is
You're going to be angry." Wu Shengli said with a smile.
"As long as one is launched, the bridge and anti-ship missile launcher will have to be repainted and polished in advance. Of course, it's okay not to paint, but it just doesn't look good." Qin Tao said: "I can't describe the specifics.
Come up here, wait for the live-fire target shooting next year, and ask people on the warship to take a photo, and everyone will know."
Wu Shengli frowned. Qin Tao kept repeating that when he waits for target practice next year, how does he know that he will definitely have live-fire target practice next year? Such supersonic anti-ship missiles are expensive, so the Navy only bought fifty of them in total. They are for use.
Every one is missing. Therefore, if it is not a major exercise project, there will never be live ammunition shooting. A few shells fired by the naval gun will be good, and the shells cost several thousand yuan each.
Is there anything going on next year?
However, in front of so many people, Wu Shengli was embarrassed to ask too many questions. Let’s ask this matter in private later!
Qin Tao just said it smoothly and didn't think too much about it. After all, it would make sense for the modern-level equipment troops to launch missiles to hit targets after one or two years. Only his father-in-law was more sensitive.
No one else took it to heart.
The leader named Lao Zhao heard what Qin Tao meant: "You mean, the missile's flame ablation is very serious?"
Qin Tao nodded: "It shouldn't be serious."
He can't say it now. Everyone will know it after the test launch.
This kind of longitudinally arranged anti-ship missile, after being launched, the tail flame can directly burn the hull. Even if a special inclined baffle is designed at the back to prevent the tail flame from jumping backward, the impact on the front hull is still very serious.
big.
The missile launch tube and the bridge shell will peel off layer by layer, just like the kind that peels off after being exposed to the sun.
I also have to admire this old man. The electronic equipment nearby must not only be moisture-proof, but also must be resistant to high temperatures!
"It seems that we still can't follow Lao Maozi's path. Our missiles are arranged horizontally and crosswise. After launching the missiles, the tail flames can be directly discharged into the sea from the side." Lao Zhao followed suit and immediately changed his mind.
"Old Zhao, this is not in line with your character. You changed your tune so quickly." Wu Shengli teased.
"When it comes to the layout of warships, I am a layman, but your son-in-law is a professional. He has already explained it. How can we, Old Zhao, still be unconvinced?"
Everyone burst into laughter. Amidst the laughter, they walked across the pier and then walked up from the back of the modern class.
The modern-class bow deck is high and has a large displacement. Therefore, when the ship is docked at the dock, the bow is more than one meter high from the dock, and the deck behind it is exactly flush with the dock, making it easier for people to get on and off.
The first thing that catches the eye is, of course, the twin 130mm naval guns.
"This kind of naval gun is really domineering. When the ground threat is not great, it can even get close to the land to provide ground artillery support." The leader of the base said: "There is one at the front and one at the front, with a total of four barrels, rapid fire.
At that time, it could match the firepower of an artillery battalion."
The rate of fire of naval guns is much higher than that of self-propelled artillery on land because it can be cooled by water cooling and also has a large loading mechanism.
"Yes, that is when we have the advantage of comprehensive air superiority. The strong can deal with the weak. For us at present, this should not be a good thing. After all, we do not have the advantage of comprehensive crushing like the US Navy."
Everyone nodded.
"For the navy, naval guns are a must, but the number does not need to be too many, one is enough." Qin Tao said: "Currently, we are imitating related products in China and manufacturing more advanced single-barreled 130
mm naval guns. In the future, our own warships with a displacement of more than 5,000 tons can be equipped with this type of naval guns, but the ones on the rear deck must be reserved for helicopters."
Many designs of the modern class are very unique. The two twin 130mm cannons are powerful enough, but they occupy the space of the helicopter, resulting in it not even having a hangar.
"Mr. Qin is right."
Walking forward from the rear deck, you can see the majestic anti-aircraft missile launcher on the second deck.
"We have obtained a lot of technology from this warship, especially its air defense missile system." Wu Shengli said: "Our navy's ability to solve the imminent air defense problem depends entirely on it."
Everyone present knows that the introduction of the Hyundai class is not for its Rizhi anti-ship missiles. There is no direct mapping of imitation Rizhi anti-ship missiles in China. It is for its ship-to-air missile system. Now, this system
It has already begun to bear fruit in China.
054 has been launched and is in the intense outfitting stage. If there were no Shikili ship-to-air missiles, the Navy would still use Sea Sidewinders as its main force.
Thinking of this, everyone was very emotional.
Everyone knows the inside story. These technologies were not obtained from the No. 136 and No. 137 in front of you, but from the ship that Qin Tao got back, the ship that was completely demolished to pieces. Each subsystem is all
It was taken away by relevant units for research.
Now, it has borne fruitful results.
From the roof radar at the top of the mast, to the band radar, to the ship-to-air missile, all subsystems have been digested and absorbed by relevant domestic units. Although the Sunburn missile has not been directly mapped and imitated, its principles have been used to develop new anti-ship missiles.
, has also started.
"It's a pity that it is not vertical launch, and it will be too complicated to modify in the future." Qin Tao said: "Now is the most glorious period of these two warships. In a few years, they will be relegated to the second line."
"Such a good warship has to take a back seat?"
"Yes, in the future, the warships of our navy will reach a peak of vigorous development. The main warships will be replaced by advanced warships with four-sided phased array radar, and the displacement will also be expanded to more than 10,000 tons. These two modern-class ships are now
It looks like a treasure, but from now on, your father will love you and your mother will not love you."
"Okay, you kid, stop trying to make a big deal out of everyone. Let's move forward and go to the bridge to see. Lao Maozi's combat command system is still remarkable." Wu Shengli said.
In front of so many people, Qin Tao made a big deal out of everyone. Wu Shengli had to stop his son-in-law from doing this.
Mr. Liu shook his head: "No, this is not a pie in the sky. I believe that what Tao Zi said will definitely come true in the future."
Many people were excited. Mr. Liu, like Wu Shengli, directly called Qin Tao Taozi? This shows that Qin Tao has gained Mr. Liu's approval!
After visiting the Modern Class, it was already half past five, and the setting sun was spreading its golden afterglow to the earth. The sea was sparkling, and the two warships were also dyed with a layer of gold, which looked extremely spectacular.
Now is the time when these two warships are at their most glorious!
