Chapter 22 Development of ** Submarines Research on rocket guidance

A disaster caused a sensation throughout the country, and it is said that the number of people killed and injured in the accident was only a few dozen, but the leaders of the kiln gang rushed to the scene in the middle of the night, and the entire organization was mobilized, and the response was very astonishing. What the people can see through this is that these people in Yaogang take people seriously. There is also the emperor in Yaogang, before leaving for Baotou to participate in the ceremony of the Yellow River Bridge in Baotou, he also rushed to the hospital to visit the wounded, which has not been heard of since ancient times. The people really felt that not only did the Yaogang people take human life very seriously, but even the emperor was different from before. It also reminded the people of the people's congress that had just ended, and everyone was thinking that maybe this might be the case with the country to be built in the future. People in Yaogang Square talked about this matter, but they didn't care much about the incident itself.

Those delegates who were still visiting Yaogang also really felt that the government here in Yaogang was completely different from the original yamen, and the officials here were thinking about things every day. There are also some delegates who are not in a hurry to go back, and they followed Emperor Chongzhen to Baotou to attend the opening ceremony of the Yellow River Bridge. The follow-up effect of the Yaogang People's Congress continues to ferment.

Because they were too busy, Mr. Li Zongwei and Lin Qing did not come back to attend the People's Congress. However, Zhang Zhimu has a lot of things to study with him, especially Fan Chengkun and their water army, and they can't study it without him coming back to participate. There are also Shi Tao, and they have some things to study with the Lin family's father and son.

When Lin Zongwei and Lin Qing rushed back, Zhang Zhimu and Fan Chengkun invited them to a meal and picked them up.

Seeing that the Lin family's father and son were in good spirits, Zhang Zhimu said: "It's good to see you like this, I'm worried that you are tired!" ”

"Hey! Now taking the car and the boat is resting, the conditions on the car and the boat are much better, we don't want anything along the way, sleep well and eat well, and now it is relaxed! Lin Zongwei said.

Fan Chengkun said: "Mr. Lin, you have to take care of your health, our navy has made a very long-term plan this time, and we still need your full support!" ”

Zhang Zhimu said: "Alas! Sometimes I feel a little sorry for Mr. Lin. For the sake of the kiln gang, your Lin family's own affairs have been delayed. Otherwise, now shipbuilders everywhere are busy, and they are all making a lot of money, and your Lin family will definitely make a fortune if you catch up with such a batch! ”

Lin Qing said: "It's because several of our shipyards are on fire, and those shipyards are also on fire!" We didn't have the opportunity to raise overseas trade so quickly, and we didn't have the opportunity to make money by building ships. ”

"Don't talk about the affairs of our Lin family, Mr. Zhang," Lin Zongwei said, "Our father and son can do things with you is our creation, and this life is worth it!" The rest is to build more ships and build good ships! ”

"Mr. Lin, let it go when you should give it to the young man!" Zhang Zhimu said, "Age is not forgiving, just give you some guidance when you have something!" ”

"Hmmm! I don't care about anything else," Lin Zongwei said, "but I really don't feel at ease about the 25,000-ton and 5,000-ton large steel-hulled ships that were being built the year before." We've put a lot of effort into this. Last year, they completed the study of the boiler for burning heavy oil, and we made up our minds to change the original coal-burning boilers of the two ships to heavy oil, which was too much work to design and modify. But now it seems that this determination is worth it. In the same way, heavy oil has much more heat than coal, and it can travel farther. Also, the conditions on the ship are much better, there is not so much soot. Besides, it is much easier to start the boiler heating. ”

Lin Qing interjected: "The efficiency of burning heavy oil is much greater than that of coal, and we can easily control the boiler by controlling the flow rate and air volume of the nozzle. It's not as cumbersome as it used to be to control pulverized coal. ”

Fan Chengkun said: "What you said is good, but in the future, when we go to the sea, we must bring enough heavy oil, and we can't replenish it halfway." This is also a problem. ”

"What Commander Fan said is," said Li Zongwei, "but we can sail far, far away with half of the oil in the original coal hold." If necessary, I thought, if we were to go out in the fleet, we would use a ship to bring our own oil. That solves the problem. ”

"I agree with Mr. Lin's decision that the use of heavy oil is a direction in the future, and if possible, we can also build supply bases in places such as Spur La and Luzon in the South Seas. It is much less labor-intensive to refuel the ship than to load coal! Zhang Zhimu said, "I don't know much about heavy oil boilers, but I want to remind you of one thing, heavy oil contains a lot of vanadium and sodium, which corrodes the bottom of the furnace very badly, and the ash at the bottom of the furnace must be cleaned frequently." In those preheating circuits, if the temperature allows, try to coat them with enamel to reduce corrosion. ”

Fan Chengkun asked: "Will it take us so long to build such a big ship in the future?" ”

"Huh! That's not slow! Lin Zongwei said, "You don't see, our slipway is working day and night." In the future, with experience, I may be able to do it faster, but not too much. Our current ships are not the same as wooden sailing ships, and they are finished without tightly building a shell. There are a lot of watertight compartments on the ship, and those internal boiler circuits and other things are very troublesome, let's just say that the cannon automatic loader, which has been done on the shore, to the ship, this change and that change, and now it has been debugged for more than a year. ”

Zhang Zhimu said to Fan Chengkun: "Now many cannons on ships use separate ammunition, and we can install less ammunition if the range is short, and different warheads can also be loaded with different ones." These are all automatic reloading, for this automatic reloading mechanism, Li Di and they spent several years of effort. It seems that the hard work pays off! ”

"If we have a few such big ships, we don't have to fight, and as soon as we open the whole world, we will be scared!" Fan Chengkun would love to build more of these ships.

"There are too many ships like this, we can't afford to build or raise them." Zhang Zhimu said, "We have a few ships as Dinghai Shenshen Needle." In the future, we will also develop diesel-powered warships of several hundred tons or more than 1,000 tons, which will be more maneuverable, have a lower draft, and adapt to various waters. Moreover, the diesel engine is more convenient and flexible to use. ”

"Mr. Zhang, this matter is also what we want to tell you when we come back," Li Zongwei said, "Small-tonnage ships can be produced using the ready-made equipment of our Lingshui Shipyard." We can't develop a higher power diesel engine in a short time, and our diesel engine is not enough for a single unit, and we can use two or even three or four units. We have the experience of producing speedboats with diesel, and I think we should first come up with a 500-ton warship, and install one 130-gun on the front and rear decks of the ship. We can build several such ships at the same time every year on our side of Lingshui. ”

"You can do it right away!" Zhang Zhimu said, "I am anxious to invite you back this time, what I want to say is that you want to develop new weapons and new ships!" ”

"Oh!"

The curiosity of all three of them was aroused by Zhang Zhimu's talk about the new weapon and the new ship.

"This weapon is **." Zhang Zhimu said, "Judging from the current situation, ** is not necessary. No other country's warships can compete with us. But if people have no foresight, they must have near-term worries. We need to develop new weapons ahead of time. This **, as the name suggests, is a kind of explosive mine that swims in the water like a fish, and explodes once it hits or approaches an enemy ship, blowing up the enemy ship. This kind of **can carry a lot**, we first develop a direct flight **, and later can also develop a guided **. ”

"Mr. Zhang, what you said is a bit interesting, but what do you use as motivation? You can't go far with rocket engine propulsion! Lin Qing asked.

"At first, you can use compressed air to drive the fan to drive the propeller, you can also use the battery as power, and then you can use kerosene and compressed oxygen combustion as the power to drive the propeller as power. In the future, it is also possible to develop a water-jet driven one. Zhang Zhimu said.

"So how do you control the depth of sailing in the water?" Lee Chong Wei asked a substantive question.

"We can control the water depth by measuring the water depth through the hydraulic valve and controlling the tail elevator at the same time." Zhang Zhimu said, "In the future, we can launch at enemy ships from the shore and from ships and planes. We now have very advanced radio technology, and we can also engage in radio guidance**. In short, this is something we will need to put some effort into developing in the future, and we will have to do it in secret! I'm just saying hello to you now, and I still need to study it with Mr. Lu and them. ”

"If you can use radio control to crash this thing into an enemy ship, no matter what ship you want, it can blow up any ship!" Fan Chengkun understands the usefulness of this thing.

"Mr. Zhang, is the submarine you are talking about a boat that dives into the water?" Lin Zongwei asked.

"That's right! Mr. Lim. Zhang Zhimu affirmed, "Our divers can dive underwater with diving equipment, but it is a solo operation." The boat I want to develop is a boat that can take a lot of people into the water together. ”

"You can't go down with your scuba gear, can you?" Fan Chengkun didn't understand what was going on with the submarine.

The father and son of the Lin family didn't understand, and Lin Zongwei asked: "What does Mr. Zhang mean, let's get a pipe to ventilate outside, and the boat is underwater?" ”

"No, we're going to build a completely sealed boat, and by controlling the air cylinders on the ship, we can control the depth of the boat under water." Zhang Zhimu said, "What you are worried about is that the crew can breathe underwater by compressing the air in the air tank. ”

"Hmm!" Lin Zongwei nodded and said, "Yes, since we can breathe with compressed air as a single diver, we can also breathe inside the submarine." ”

"Huh! That's true, but in reality there are so many things to solve. Zhang Zhimu said, "Let's talk about air, after we inhale the air and absorb the oxygen in the air, we exhale carbon dioxide." In an enclosed space, if the carbon dioxide is not removed as soon as possible, people will soon be poisoned. Therefore, air purification devices are a matter that needs to be well studied. And then there's motivation. Of course, we can use the diesel engine as power, and when we are sailing on the water, we can directly use the diesel engine to generate electricity and charge the battery pack. After a full charge, the submarine dives into the water, and to maintain the pressure in the submarine, the control system is very complex and reliable. We will study these things carefully with Mr. Lu Bingyi, and then divide the work into several large parts, and study and solve them separately, and after these key technologies are solved, we will work together to build submarines. ”

"Oops! If we build a submarine, we can shoot under the enemy ship without noticing, suddenly emerge from the water, and open fire on them! Speaking of this, Fan Chengkun was a little excited.

"What if you could shoot ** at enemy ships underwater?" Zhang Zhimu asked, "Think about it, what will happen if we go underwater to the enemy's coast, send special forces to set off from the submarine, dive to the enemy's shore, and quietly retreat from underwater after completing the mission?" ”

"That's right!" Fan Chengkun said, "If this is the case, the whole naval battle in the future will be different!" ”

"Another advantage is that after the submarine dives into deep water, there are no waves, and it will be very smooth. Of course, the underwater air is definitely not as good as the water surface, and the small space will be very uncomfortable. But with the current level of our opponents, we make a snorkel to extend out of the water to ventilate, and the enemy generally can't find it! Zhang Zhimu said.

Lin Zongwei scratched his head and said: "Mr. Zhang, this submarine matter is not something that can be done in a short period of time, there are too many things that need to be solved, and we must have a long-term plan." ”

"yes!" Zhang Zhimu said, "These things we have to assign to various departments to study, and many of our things in the future may not be solved by one department independently, and they need to be studied for a long time." By the way, there is one more thing, the artillery you are now on board the ship, with separate ammunition, the firing table is already very complicated. I'm wondering if it's better to build an air-conditioned room on your big ship and install a computer in it. Store the meter and other things in the computer, so that as long as the conditions are injected, there is no need to manually calculate, and the computer will automatically display the meter parameters, which is not very convenient. ”

"Oh!" Lin Zongwei was stunned, "The computer still has such a big ability?" Of course it's good to have this stuff! "Lee Chong Wei doesn't know much about computers.

Zhang Zhimu said: "In fact, computers can do much more than that. We can train some talents who understand both computers and the situation on board through computers. These people will be able to manage a lot of shipboard operations with computers in the future. ”

"Electronic things are too delicate, if the computer you said is broken, will our ship be in trouble?" Lin Qing was very worried about the reliability of the computer.

"The things on our ship can be controlled manually and computer-controlled. Of course, for added reliability, two sets of computers can be installed on board in case of an emergency. Zhang Zhimu said, "The computers we are building now are all cost-free, but this investment will have a very rich return in the future." ”

After talking with the Lin family's father and son and Fan Chengkun, Zhang Zhimu remembered Li Wei's rocket again, and called Li Wei to invite him to the office.

Li Wei was still that kind of big grin, and as soon as he entered the room, he said to Yang Yulin: "Mrs. Yang, I'm thirsty, get some water!" ”

Yang Yulin said angrily: "Yo! The score is not small! When did you even change your name? ”

Like Li Jing, Li Wei really didn't dare to come with Yang Yulin, "Oops! It should have been called Mrs. Yang a long time ago, you can't always call Miss Yang Miss Yang! In order to change the topic, he immediately asked Zhang Zhimu, "What is the matter with Mr. Zhang looking for me?" ”

"You kid, now that you're a general, you can't be stable." Zhang Zhimu said, "Wait for Yang Chang, he will be there in a while!" We'll look into something together in a moment. ”

After a while, Yang Chang led a few people in. Everyone sat down, Zhang Zhimu asked Li Wei: "Li Wei, tell me, how far can your current rocket shoot?" ”

"It's no problem how far it goes, we can increase the charge, and we can shoot to sixty or seventy kilometers! But the problem is that the shooting accuracy has not been able to break through! Li Wei said, "This thing is greatly affected by temperature and wind speed. ”

Zhang Zhimu said: "There is no way to improve the accuracy of this uncontrolled rocket!" We invited Yang Chang and them over today to engage in the issue of self-guided control. Today we are studying two things, one is long-range guidance, and the other is close-range visual guidance. ”

After a pause, Zhang Zhimu said again: "Guidance is to control our rocket to fly to the predetermined target. Our rockets can be equipped with an upper tail rudder to control the direction of the rocket's flight and correct the direction of deviation! ”

"Oops! If you can control the direction of flight, then long-range rockets are a sharp weapon on the battlefield! Li Wei said.

Yang Chang understood Zhang Zhimu's words, "We can control the direction by controlling the tail rudder, the problem is that we must first know the position of the rocket itself." ”

"That's the first question I'm going to tell you, we're going to develop a gyroscope." Zhang Zhimu said, "Everyone has played with gyroscopes, and we make gyroscopes based on this principle." In physics class, I told you about this principle. The spinning top will rotate around another fixed axis while constantly rotating, which is the spinning of the top, also known as the rotation effect. We can use this principle to make gyroscopes. The gyroscope, together with other sensors, can indicate the level, pitch, and heading of the flying object for us, and navigate the flying object and the boat. ”

Zhang Zhimu drew a simple schematic diagram of a gyroscope that can move freely on three axes on paper, "Let's see, this is the structure of the gyroscope." But the gyroscopes we actually make have a lot of auxiliary mechanisms, because no matter how high-precision bearings we use for several axes, there will be friction, and there must be external forces to ensure their stable speed. This is an electromechanical device, with which we can measure how far the flying object is from its original position and what direction. It can be said that we are the basis for control. We have to solve this problem first. ”

"If we had this thing, it would be easier to control the attitude on our planes!" Li Wei said, "Yang Chang, you have to find out this as soon as possible!" ”

Zhang Zhimu said: "I studied with Mr. Lin Zongwei today and considered installing computers on their newly built big ships and using computers to build artillery firing meters. I see that there are gyroscopes, and in combination with computers, they can also calculate and store tracks. ”

"I think it's okay," Yang Chang said happily, "The computer we use now has been used without downtime, and there are basically no major problems." I also want to try to make it as easy as possible for everyone to use it, so that we can find problems in the process of using it. A few days ago, Li Di and the others came to me, and I suggested that their subway control system should be managed by computer. We have roughly thought of a preliminary plan, preparing to put three computers in the subway control room to ensure the safety of use. ”

Li Wei couldn't help it, "Hey! After talking for a long time, how can our rockets be controlled? ”
