Chapter 240 I want to build a marine diesel engine factory
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.
"President Qin, didn't you say that the Star Wars plan during the Reagan era was a scam?" Mr. Wu asked: "It will be too difficult to intercept intercontinental ballistic missiles unless we use nuclear bombs to deal with nuclear bombs like Lao Maozi did!"
Although in last year's war in the oil region, Patriot missiles intercepted Scuds many times, but those were only short-range missiles with a range of 300 kilometers.
The farther the range and the faster the missile, the more difficult it is to intercept. When it comes to the level of intercontinental ballistic missiles, the interception technology required is quite high.
The interception was not accurate 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, which was almost as good as 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, it turned out that 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-Ballistic Missile Treaty? This thing is in the way. If possible, just withdraw from it." 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 develops this kind of 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 side prepare carefully
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.
An error can make a huge difference, so this kind of interception must be absolutely accurate. As a result, if the interceptor missile just takes 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 propose a toast to 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 person. There were too many people just now and they were chatting all the time, so he didn't introduce this unknown person. Now, Qin Tao looked at the other person questioningly, and then searched for it in his memory.
What.
"My surname is Wen, and I come from No. 703 School. I was born in 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 is only in his fifties now. But looking at 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.
Mr. Wen 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?"
The crowd burst into laughter again.
"Lao Wen's technical skills are a bit lacking. 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.
Mr. Wen is versatile. He is not only technically gifted, but also artistically powerful. He plays the French horn to perfection, at a master level.
"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 horns. It has so many overtones that it can produce a lot of sounds even without pressing the keys."
This chapter is not over yet, please click on the next page to continue reading! "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. If we encounter something unhappy, we will have a way to vent."
"Look, this is the French horn player. He can play it without a horn," Mr. Lin said, and everyone laughed again.
After laughing, Wu Shengli said: "Taozi, we gave all the information you got back to the 703 Institute for them to summarize and sort it out. 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 LM2500 gas turbine from the United States. 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 warships.
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.
With the help of the latest technical information, Sibei can be improved to 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?
What is currently promising in China is the modification of Spey. After all, this kind of engine has already had a successful example. The British are using it, and the islanders are also using it. If it continues to develop, it is still quite good.
However, the biggest problem with Sibei is that it cannot be fully produced domestically!
When the Flying Leopard fighter-bomber came out, the Navy was very satisfied and purchased a batch. But what happened? Later, the engines in stock were used up, and there were no engines available for the newly built aircraft in the aircraft factory!
I bought all the technical data back then and planned to make it domestically, but what happened? It was not until 2003 that the engine codenamed Turbofan-9 could be produced by ourselves. Moreover, the initial output was very low, and it was only supplied to Feibao.
Is it feasible to place our hopes on Sibei?
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 difficult to pin your hopes on this kind of engine!”
Everyone present was deep in thought.
Qin Tao is right.
It is very risky to improve a gas turbine with an engine that cannot be produced by oneself. Moreover, it is said that the British side has discontinued the production of Spey engine, so even if we want to buy it, we cannot buy it.
"Mr. Qin, do you have any other plans?" Mr. Wen asked.
"Well, let's talk about it 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 such an 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
People, all their hard work is in vain.
When the time comes, will you scold Qin Tao as a comprador?
Qin Tao didn't want to be scolded. It was his father-in-law's business to be scolded, so he simply didn't say anything.
It's impossible not to talk, 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, need a marine diesel engine factory now."
We are talking about the power system anyway, so 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.
Matching is done.
"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."
Almost all the existing marine diesel engines in the country were imported from Lao Maozi in the 1950s and 1960s. The larger ones include Bincheng Diesel Engine Factory, the diesel engine factory affiliated to Huating Shipyard, China Southern Locomotive and Rolling Stock Corporation, etc. However, these companies
The diesel engines produced are very old and cannot keep up with the development of the times.
To say that it is slightly more advanced, it is probably the MTU diesel engine introduced by the Coal Provincial Diesel Engine Factory, which has reached the international advanced level in the 1980s and is still used as the auxiliary power system and diesel engine unit 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 engage in 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 sent 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 a later statistic, from 1982 to 2001
20 years old
During the year, domestic shipyards built a total of 2,664
ships,1692.6
Ships with a gross tonnage of 10,000 tons have a total of 3,691 diesel engines installed
Taiwan,853.6
Thousands of kilowatts, including 1851 Chinese-made hosts
Taiwan, 5.681 million kilowatts, imported main engine 1503
Taiwan,259.5
Thousands of kilowatts, and some hosts with unknown statistics 337
Taiwan, 260,000 kilowatts. In terms of number of units, domestic hosts account for 50% and imported hosts account for 41%. In terms of power, domestic hosts account for 67% and imported hosts account for 3%.
ten.
Let’s take a look 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?"
"The Pioneer Machinery Factory in Lu'an, Mainland China, was established in 1968 and specializes in the production of military diesel engines."
Qin Tao quickly shook his head, don't touch this thing, it is definitely a trap!
At that time, when the North was facing a war crisis at any time, the country began to engage in third-line relocation, and a large number of military industrial enterprises were relocated to deep mountains and old forests. In a war environment, this kind of consideration was necessary, but as the problems in the North eased
, with the opening of the country, all third-tier factories are no longer dumbfounded.
In the deep mountains and old forests, where no one can poop, even if they operate normally, the transportation cost is much higher than that of factories on the coast. They are simply unable to 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 you stay there for the rest of your life. How do you find a wife? How do you solve the problem of children’s education?
The same was true for the Pioneer Machinery Factory. In the 1990s, everyone in the factory flocked to the provincial capital, 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 even remembering what day it was.
"When talking about 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, the 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. Bincheng Diesel Engine Factory built it in its own Reed
In the workshop set up in a shed, we worked hard all night to build a two-stroke six-cylinder low-speed diesel engine with a cylinder diameter of 600 mm and a stroke of 1060 mm.
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 with billowing black smoke, but it was towed back! Even so, a movie was still made at the time called "Trial Sea" to record this
In a great era, the famous actor from "The White-Haired Girl" was still used.
This period of history is very touching.
"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 is something fishy in this!
It was not until the 1980s that I repurchased it. After twenty years and several times the amount of money, I finally had a stable and reliable marine low-speed diesel engine in China. Thinking of this incident makes people extremely sad.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "By the way, I heard that a machine-building wizard is coming from the island country to inspect the Bincheng Diesel Engine Factory to help them with technological transformation."
"Machine-making god?" Qin Tao became interested now: "Could it be 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. (People in the island country like to call it Co., Ltd., so let’s just use the company name. 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 Shipyard was 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. Later, they built the world's largest oil tanker with a displacement of 480,000 tons. Ishikawajima Harima Heavy Industries has many branches.
Hikoda Jutsuo is in the 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 they were involved in related RND
Type and RND-M
Based on the IHI-SULZER diesel engine, the IHI-SULZER RLA has been developed with long stroke, low speed, high power and low fuel consumption.
type diesel engine.
Their technical strength is very strong, 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 Hikoda Shizuo 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 easier to move things. We must first move our own factory
