Chapter 241 I want to build a marine diesel engine factory (more updates, please subscribe)
National anti-missile system?
There were many people working on the aerospace system present, and they were all a little surprised when they heard Qin Tao say this.
“Mr. Qin, didn’t you say that the Star Wars plan during the Reagan era was a scam?” Mr. Wu asked: “Intercontinental ballistic missiles will be too difficult unless we use nuclear bombs to deal with them like Lao Maozi did!”
Although Patriot missiles intercepted Scuds many times during last year's war in the oil region, they were only short-range missiles with a range of 300 kilometers.
The longer the range and the faster the missile, the more difficult it is to intercept. At the level of intercontinental ballistic missiles, the interception technology required is quite high.
The interception accuracy was not enough, so Lao Maozi used nuclear bombs to make it work. However, even if the interception was successful, the nuclear bombs exploding in outer space would pose a serious threat to Lao Maozi's capital, almost as if there was no interception.
In the 1980s, in order to bring down the old man, the Americans proposed the Star Wars plan. It was like a science fiction blockbuster. At that time, many people questioned it. Now, the doubts have become a reality. The Americans are just fooling the old man. Maozi, but Lao Maozi took it seriously.
Now, Qin Tao says that the Americans will try to develop this kind of anti-missile system, which sounds unbelievable.
Qin Tao nodded: "Yes, the technology is too difficult. There is no air in outer space, so we need to develop a special mobile interceptor propelled by a vector engine and conduct precise impact. This is simply impossible. However, we have a saying As the old saying goes, as long as an iron pestle is ground into a needle, a certain country will definitely do this in pursuit of its own absolute security."
“Then they will violate the anti-missile treaty.” Someone said.
"Anti-missile treaty? This thing is in the way. If the worst happens, just withdraw." Qin Tao said.
"Then what should we do?" Mr. Lin became concerned there. He could think that once the other party really pursues unilateral security and creates such a system, other countries will not be safe. The most important thing in this world is Balance, once the balance is broken, something will happen sooner or later.
“We currently do not have the ability to research related technologies.” Mr. Wu said.
It is now very difficult to intercept a short-range ballistic missile, let alone an intercontinental ballistic missile. In this regard, China is too far behind.
"Yeah, we don't have the ability to research these technologies, and we don't need to. We just need to develop some other technologies, such as aerial orbit-changing technology, such as fake warhead technology, such as water-killing technology, etc., and let the other party carefully prepare them. All interceptions failed."
It is not easy to intercept missiles launched from outer space. It even requires observation from the take-off stage and calculation from behind. In this way, interception can only be carried out when the ballistic missile flies over the highest point and falls.
A slightest error can make a thousand miles difference. This kind of interception must be absolutely accurate. As a result, if the interceptor missile has just taken off and the target suddenly changes its trajectory, the interception will most likely be in vain.
There is a big gap between the cost of interception and the cost of changing attack methods.
Those present nodded.
"Mr. Qin, you are our lucky star. As long as you are here, you will definitely be able to get us what we need. I'd like to toast you." At this time, a person on the table who had not interrupted until now spoke.
"Excuse me, what is your name?" Qin Tao looked at the other party. There were too many people and they were chatting all the time, so he did not introduce this unknown person. Now, Qin Tao looked at the other party questioningly, and then searched for it in his memory. What.
“My surname is Wen, and I come from No. 703 School. I am from Mingzhou, but I have been working in Bingcheng after graduation.” The other person introduced himself.
Qin Tao finally connected with the memory in his brain. He looked at the person in front of him and sighed: "Based on your age, it's not too much to call you old, but from your perspective, It's just right for me to call you Uncle Wen, or even Brother Wen."
No wonder Qin Tao didn't recognize him immediately, he was so young!
Mr. Wen was born in 1940, and he is only in his fifties now. But judging from his age, some people believe that he is in his thirties. He is completely different from other old people, so much so that Qin Tao did not dare to recognize him. After all, in his previous life The first time he saw Wen Lao was already in the new century.
Wen Lao graduated from Huating Jiaotong University in 1962 and joined the 703rd Research Institute of China Shipbuilding Industry Corporation in the same year. He became the chief engineer in 1982 and the director in 1992.
He has been working for more than thirty years, but his young appearance makes it difficult for people to associate him with the identity of a director. At this time, when he heard Qin Tao say something like Uncle Wen, or even Brother Wen, Mr. Wen Smiling and waving his hands: "Don't say that, otherwise, they will say you are a monster."
A fifty-year-old man with a thirty-year-old face really looks like a monster. When he heard what he said, Mr. Lin immediately joked: "Old Wen, you must have eaten Tang Monk's meat. What does the meat taste like?" Is it yummy?"
Everyone burst into laughter again.
“Lao Wen is a little talented when it comes to technology. He should be an artist. It’s a pity that he didn’t bring his precious French horn today, otherwise he could have played a piece for us.” Wu Shengli also said with a smile.
Wen Lao is multi-talented. He is not only technically gifted, but also artistically powerful. He plays the French horn to a superb level, almost to the level of a master.
"When I was at Huating Jiaotong University, I joined the art troupe and played this." Mr. Wen also recalled that period of history: "At that time, the teacher asked me to listen to music while someone played the piano. I listened to it once and didn't remember it. I asked someone to play it again, but I still didn’t remember it. The teacher played it for me five times before I could sing it.”
“The French horn is not easy to play.” Qin Tao said: “I heard that this kind of horn is called the king of trumpets. It has so many overtones that it can produce a lot of sounds even without pressing the keys.”
"Mr. Qin, do you also play music?" Mr. Wen was surprised.
Qin Tao shook his head: "I don't play, but I like to listen. This thing can cultivate sentiment."
"Yes." Mr. Wen sighed with emotion: "The French horn seems to be just a thing for fun, but in fact it has a great effect on cultivating sentiments. There are also paintings and the like, which seem to have nothing to do with our scientific research, but... When we combine technology and art, our products will be more perfect, and we will have more hobbies and interests, and if we encounter something unhappy, we will have a way to vent."
“Look, this is the French horn player. He can play without a horn.” Mr. Lin said, and everyone laughed again.
After laughing, Wu Shengli said: "Taozi, we gave all the information we got back to the 703 Institute for them to summarize and organize. After all, they are professionals."
At that time, Qin Tao just casually said something like 606, 624, etc. However, the Navy attached great importance to it. After some research, it was decided to hand it over to the 703 Institute. After all, this institute was the counterpart.
Institute 703 was established in 1961. It initially studied boilers and steam turbines. Later, it began to develop gas turbines. In this area, it already has a lot of experience. As for Wen Lao, he is deeply involved in this field. for many years. In the 1970s, he presided over the project of converting large-scale aero engines into marine gas turbines in China, but could not be shipped due to lifespan issues.
Now that Mr. Wen has spoken, he must lead the topic to marine gas turbines.
"We originally introduced the American LM2500 gas turbine. This engine is very advanced and makes us sigh. Unfortunately, we can no longer import more engines of the same type. Even if someone sends a brand new one, it will be for our export battleship. We can't use it ourselves." Mr. Wen said: "Currently, our country has pinned its hopes on the modification of the Spey engine. The prototype of this gas turbine is currently being assembled. Based on the technical data, we can improve Sibei and become a qualified power system for our warships."
What?
After hearing what Mr. Wen said, Qin Tao realized that he had overlooked something.
How should the development of marine gas turbines proceed?
The most promising engine in the country right now is the modification of Spey. After all, this kind of engine already has a successful example. The British are using it, and the islanders are also using it. If it continues to develop, it will be quite good.
However, the biggest problem with Sibei is that it cannot be fully produced domestically!
At that time, the Flying Leopard fighter-bomber was born. The Navy was very satisfied and purchased a batch. What was the result? Later, the engines in stock were used up, and there were no engines available for the newly built aircraft in the aircraft factory!
At that time, I bought all the technical information and planned to produce it in China. What was the result? The engine code-named Turbofan-9 was not able to be produced by itself until 2003. Moreover, the initial production volume was very low, and only Feibao was supplied.
Is it feasible to place our hopes on Spei?
Seeing Qin Tao frowning, Mr. Wen asked curiously: "Mr. Qin, do you have any doubts about Sibei's modification? This kind of engine has been used on many warships and should be mature and reliable."
"Yes, for those countries, it is mature and reliable, but for us, it is not necessarily the case. After all, our relevant units are not yet capable of independently producing Spey engines. We can assemble a marine engine with imported parts. , but it’s very risky to pin your hopes on this kind of engine!”
Everyone present was deep in thought.
Chin Tao is right.
It is very risky to improve the gas turbine with an engine that cannot be produced by oneself. Moreover, it is said that the British side has discontinued the Spey engine, so even if we want to buy it, we cannot buy it.
“Well, let’s talk about this later, maybe there will be an opportunity in the future.” Qin Tao said: “After all, I am not a relevant professional, so I won’t express my opinion.”
Of course, Qin Tao has something to say. Getting gas turbines from Lao Maozi has been proven by history to be a feasible path, and this opportunity was available in 1993.
However, Qin Tao couldn't say.
Once this road is taken, the road to the modification of Spey will be blocked. The Navy cannot support two projects at the same time, and the Navy's warships cannot have two kinds of gas turbines at the same time. Those technologies that have been busy working on the modification of Spey for many years Staff, all the hard work is in vain.
At that time, will you scold Qin Tao as a comprador?
Qin Tao didn't want to be scolded. If he was scolded, it was his father-in-law's business, so he simply didn't say anything.
It’s impossible not to speak, so just change the subject.
“You are all elites in the industry. Do you have any news? Which diesel engine factory is about to die? We, Mingzhou Shipbuilding Industry Group, are in need of a marine diesel engine factory now.”
Since we are talking about the power system anyway, let’s just talk about the power system.
If a shipyard only builds ships, it will not make much profit. After all, shipbuilding is actually just welding a hull, and the main engine and other things on it have to be outsourced. If you can produce marine diesel engines yourself, you can provide them yourself in the future. Got a matching package.
"Mr. Qin, you have such foresight. In the future, Mingzhou Shipbuilding Industry Group will become the backbone of our domestic shipbuilding industry!" Mr. Wu sighed with emotion: "You already have a propeller factory, and now you are going to build a diesel engine factory! "
There are many marine main engines, from the oldest steam engines to the most advanced gas turbines. However, the most commonly used ones are diesel engines. After all, they start quickly, have high power and low fuel consumption. After the 1950s, marine diesel engines have almost replaced them. Steam engines, except for some special ships that also use steam engines (for example, some ships need steam to preheat their cargo), most ships have begun to use diesel engines.
"Mr. Qin is so capable, he can package a marine diesel engine factory from Lao Maozi." Someone also said.
Qin Tao shook his head: "No, Lao Maozi's technology is backward and cannot meet our needs."
Most of the existing domestic marine diesel engines were imported from Lao Maozi in the 1950s and 1960s. The larger ones include Bincheng Diesel Engine Factory, the diesel engine factory affiliated with Huating Shipyard, China Southern Locomotive and Rolling Stock Corporation, etc. However, the diesel engines produced by these companies are very old and cannot keep up with the development of the times.
ˆ To be more advanced, it is estimated that the MTU diesel engine introduced by the Coal Province Diesel Engine Factory has reached the international advanced level in the 1980s and is still used as the auxiliary power system and diesel engine set of warships.
However, this is a high-speed diesel engine, and the most commonly used on ships are medium-speed and low-speed diesel engines.
Qin Tao wants to develop gas turbines, but he doesn’t have the strength yet, but he can already try marine diesel engines. After all, the Belgians have come and given him money. With that money, he can definitely start a diesel engine project!
The development of domestic marine diesel engines is quite backward, and the gap is also huge.
According to statistics from later generations, in the 20 years from 1982 to 2001, domestic shipyards built a total of 2,664 ships with a gross tonnage of 16.926 million, and installed a total of 3,691 diesel engines with a capacity of 8.536 million kilowatts, of which 1,851 were domestic engines with a capacity of 5.681 million kilowatts. kilowatts, 1,503 imported hosts, 2.595 million kilowatts, and some unknown hosts, 337, 260,000 kilowatts. In terms of number of units, domestic hosts account for 50%, and imported hosts account for 41%. In terms of power According to statistics, domestic hosts account for 67% and imported hosts account for 30%.
Looking at the current products of Mingzhou Shipyard, from catamarans to bulk carriers of 150,000 tons, almost all marine main engines are imported, and very few are domestically produced.
Why should foreigners earn this money?
"There are currently no suitable diesel engine factories in our country. There is a third-tier diesel engine factory with abandoned factory buildings and a large amount of equipment. If you want it, you can probably buy it for just one dollar like the water pump factory in Huating. It's possible." Sure enough, there are many people and knowledge, and the big guy actually found one for Qin Tao.
“A third-tier diesel engine factory?” Qin Tao asked curiously: “Where?”
“Inland, Lu’an, Pioneer Machinery Factory was established in 1968, specializing in the production of military diesel engines.”
Qin Tao quickly shook his head. Don’t touch this thing. It’s definitely a trap!
At that time, when the north was facing a war crisis at any time, the country began to carry out third-line relocation, and a large number of military industrial enterprises relocated to deep mountains and old forests. In a war environment, this kind of consideration is necessary. However, as the problem in the north eases and the country opens, no third-tier factories are dumbfounded.
Even in normal operations in deep mountains and old forests, where no one can poop, the transportation cost is much higher than that of factories on the coast. They simply cannot adapt to market competition. After losing the support of the country, they have to be abandoned.
Not to mention technicians who are accustomed to life in big cities, who would go to work in a third-tier factory? It doesn't matter if I stay there for the rest of my life, how can I find a wife? How to solve the problem of children’s education?
The same is true for the Pioneer Machinery Factory. In the 1990s, people in the factory flocked to the provincial capital one after another, and the factory was completely abandoned. Even if Qin Tao bought the factory for one yuan, he could not hire people. Update Equipment!
Qin Tao would rather build a brand new diesel engine factory in Mingzhou than touch a third-tier factory.
“When it comes to domestic marine diesel engine factories, we have to look at Bincheng. In recent years, Bincheng Diesel Engine Factory has developed so fast!” The guys didn’t understand Qin Tao’s mood and started discussing again.
At this time, even Wu Shengli came off the stage to participate in the discussion, without remembering what day it was today.
“Speaking of Bincheng Diesel Engine Factory, I think of the first 3,000-horsepower marine diesel engine they produced back then. This satellite was really big at that time.” Wu Shengli said with emotion.
In that era, everything was possible.
At that time, Bincheng Shipyard had already built a 4,500-ton Daqing No. 9 freighter. This freighter planned to purchase two medium-speed diesel engines imported from Germany. Later, it was decided to make its own. In the workshop set up in a shed, we worked hard all night to produce a two-stroke six-cylinder low-speed diesel engine with a cylinder diameter of 600 mm and a stroke of 1060 mm. Then we announced the good news to our superiors with drums and gongs. We built three Thousand horsepower diesel engine!
After it was loaded into the engine room of the Daqing 9, it was driven to the sea for a sea trial despite the billowing black smoke, but it was towed back! Even so, a movie was still made at that time called "Trial" to record this great era, using the famous actors from "The White-Haired Girl".
This period of history is full of emotions.
“However, fortunately, the technology we introduced from the Sulzer Diesel Engine Factory in Switzerland has finally come to fruition. It’s just twenty years late.” Someone sighed again.
In 1963, China finally made the decision to introduce a series of 25 models from Switzerland, ranging from 3,000 horsepower to 27,000 horsepower. After the successful introduction, it can greatly promote the development of domestic diesel engine technology.
However, some domestic units have stopped working. The 8,800-horsepower diesel engine we manufactured has been ignited and will be successful soon. Why do you spend precious foreign exchange to buy foreign engines? There's something fishy about this!
It was not until the 1980s that I repurchased it. Twenty years later and several times the amount of money was spent, and finally a stable and reliable marine low-speed diesel engine was available in China. Thinking of this incident makes people extremely sad.
“By the way, I heard that a machine-building genius is coming from the island country to inspect the Bincheng Diesel Engine Factory and help them with technological transformation.”
"The **** of machine building?" Qin Tao became interested at this moment: "Could it be the Hikoda Shizuo?"
The speaker opened his mouth wide: "Mr. Qin, you are really amazing, you guessed it right away!"
Qin Tao smiled: "Our industry is not very big. He comes from the island country and is a machine builder. I thought of this person."
Speaking of shipbuilding companies in the island country, it is easy to think of Kawasaki Heavy Industries and Mitsubishi Heavy Industries. In comparison, Ishikawa Harima Heavy Industries does not seem to have a very famous name. In fact, this old company is also a part of the heavy industry in the island country. For example, the famous Izumo-class helicopter carrier of the island country comes from this company. (Islanders like to call it a company, so we’d better use the name company. It’s simple.)
Ishikawajima Harima Heavy Industries was founded in the mid-19th century. After its establishment, it began to manufacture Western-style warships for the island nation of Japan. In the subsequent development process, they successively manufactured the first steam-powered ship and the first set of thermal power generation for the island nation. equipment, the first jet engine.
From these, we can see how strong their technical strength is. After the end of World War II, they began to develop the civilian shipbuilding industry. For example, Wu Shipbuilding is one of the leaders. It built the world's first 100,000-ton oil tanker back then. It was built here.
In the 1960s, they continued their efforts and built the world's first 200,000-ton oil tanker, and later the world's largest oil tanker with a displacement of 480,000 tons. Ishikawajima Harima Heavy Industries has many branches. Hikoda Shitsuo was in his subordinate machine-building company.
They have manufactured many advanced engines. Even aero engines and American F-15 fighter jets, after being exported to island countries, the F100 engines on them were all produced under license from this company.
As for marine diesel engines, after the end of World War II, they entered into technical cooperation with the Swiss Sulzer Company in 1950 and produced a large number of marine low-speed diesel engines. Soon, based on the related RND and RND-M diesel engines, they developed IHI-SULZER RLA diesel engine with long stroke, low speed, high power and low fuel consumption.
They have strong technical strength, so they were invited by Bincheng Diesel Engine Factory to see if they could carry out the same technical transformation. After all, Bincheng Diesel Engine Factory is also currently producing Sulzer diesel engines in large quantities.
“When will this Hikota Shitsuo come?”
“I guess tomorrow or the day after tomorrow.”
PS: I don’t know if you like to watch the plot of going to Lao Maozi’s place to get things. After this plot is over, continue to go to Lao Maozi’s place. Now that the Red Empire has collapsed, it is even more convenient to move things. We must first develop our own factory and go there soon.
