"What's going on?" Mr. Zhu ran over quickly. Because he only had one arm, he almost fell down several times while running.
"Mr. Zhu, don't be anxious, please slow down." Qin Tao quickly supported Mr. Zhu: "The smoke is gone, there shouldn't be a big problem."
Zhu Lao then stopped running, but he was still walking very fast. At this time, the tank crews had finished extinguishing the fire and skillfully opened the rear engine compartment cover.
The armor on the front of the tank is thick and can withstand attacks from various anti-tank ammunition, but the armor on the back is very weak, similar to the steel plates of ordinary armored vehicles. At the same time, the armor on the back can also be opened to facilitate use in the wild. In this case, lift the engine as a whole.
After opening it, you can see where the fire is. After seeing it clearly, several people were helpless.
“The turbocharger leaked oil and the entire turbocharger had to be replaced. Fortunately, it was discovered in time and other parts were not damaged.”
Modern tank diesel engines all use exhaust gas turbocharging, which means to collect the exhaust gas from the engine exhaust pipe and blow the turbine blades to rotate at tens of thousands of rpm, and then drive the blades on the other side to pump the engine. Get air in. Compared with the previous supercharger that needed to be driven by a crankshaft wheel, this method does not consume additional power and purely uses exhaust gas, so it is very popular among engine engineers.
The exhaust gas from the engine is also very hot, so if it is operated at full power for a long time, the entire turbocharger will turn red. If there is oil leakage, it will directly cause a raging fire.
Fortunately, it was just a rehearsal for the military parade and there was no need to drive too fast, so there was only smoke and no direct fire. This was a blessing among misfortunes.
"Replace the turbocharger." Mr. Zhu said: "The life of our turbocharger needs to be further reduced. Let's set it at 800 hours for the time being."
"What, eight hundred hours?" Qin Tao was a little shocked: "Why? A car's turbocharger can last hundreds of thousands of kilometers. Isn't the one in your tank too worn out?"
When it comes to turbocharging, many people will sneer at it, saying that it has a short lifespan. In fact, as long as it is properly maintained, a turbocharged engine can run hundreds of thousands of kilometers, and it will not be a problem for normal household use until it is scrapped. In the 1990s, , turbochargers are already standard on Steyr trucks and have a long service life.
Even though Qin Tao is a shipbuilder, he also knows the parts of vehicles. He was shocked to hear that he only had these 800 hours.
"How can a tank engine be compared with a normal car engine? Our previous Type 59 tank engine had to be overhauled after 500 motorized hours. Now our 150HB engine has a lifespan of 3,000 hours, which is already very good. , if we want to pursue a power of 1,200 horsepower, it is impossible to achieve the same lifespan as a civilian engine. However, our turbocharger is really lagging behind. When we originally tested it, we set a lifespan of 1,000 hours. , now it seems that it still needs to be compressed.”
“Do you need help?” Qin Tao asked: “If you need it, our Huating Machinery Factory can help with production.”
This factory was the former Huating Second Water Pump Factory. It was a factory acquired by Mingzhou Group in the early days. It later became a supporting factory for the shipbuilding industry, ranging from waterjet propellers to variable pitch propellers and submarine seven-blade large skew propellers. , until now, the lift fans and other components prepared for vertical take-off and landing fighter aircraft are all products of their factory.
Since there are difficulties in manufacturing this turbocharger, Mingzhou Group can certainly help.
Zhu Lao's eyes suddenly lit up, yes, why didn't he think of asking the aviation company for help?
The development of the 150HB engine is not easy. They have thought of various ways and developed various new production processes to solve technical problems one by one. Some problems have been solved, and some problems have not yet been solved.
For tank engines, the advanced high-performance turbocharger is the main factor that enables it to output strong power. The more powerful the supercharger is, the greater the engine’s output power is. However, the greater the boost ratio of the supercharger, This means that its manufacturing will be more complicated.
In terms of advanced tank power systems, military workers have also taken one step at a time, and have been catching up to the most advanced level in the world. Yes, the most advanced level in the world. After that, domestic tank diesel engines have caught up with and surpassed German tanks. Diesel engines have entered the first echelon.
Britain, which was once the most arrogant, stagnated for a long time after developing the 1,200-horsepower diesel engine used in the Challenger tank, so that in later generations, tanks sold for export needed to be equipped with European power packages.
The maverick French knew that it would be difficult for them to develop an advanced tank diesel engine, so they simply started from scratch and used a gas turbine as a turbocharger for the diesel engine. They built an alternative ultra-high-supercharged diesel engine based on the eight-cylinder engine. Achieved a power output of 1,500 horsepower. However, this thing is very expensive to use and maintain, so when this tank was exported, it was also replaced with a European power package.
The European power package is Germany's most advanced tank diesel engine. On the Leopard-2 tank, Germany developed the MB873 engine. This engine was the first to achieve a power output of 1,500 horsepower, but it used a method of increasing the speed. This While the power reaches the standard, it also generates a lot of heat, which consumes more than 200 horsepower for heat dissipation.
Later, the Germans came up with the MB883 engine with reduced bore and stroke, coupled with the advanced Lenk gearbox, it became the European power package.
Technically speaking, it is indeed more advanced than the 150HB used on the 99 tank. Even if the domestic engine is upgraded, it can output the same 1,500 horsepower. There is also a gap in life and fuel consumption.
However, while the development of the West has stagnated, the tank designers of the motherland still have not given up research. When developing plateau tanks, they started from scratch and used an 8-cylinder 132 engine. With the help of a two-stage supercharger, the plains The area can achieve an output of one thousand horsepower. If it is increased to 12 cylinders, it can reach one thousand five hundred horsepower. Moreover, because of its small displacement, its size is also small, which will make the layout of the tank easier. .
Even though he is engaged in the shipbuilding industry, Qin Tao also understands these basic common sense, and his own tank technology will continue to develop, eventually becoming the world's strongest ground combat vehicle. This is inseparable from the hard work and development of these people in front of them, so if Qin Tao can help, he is willing to help.
Hearing that Qin Tao wanted to help, Mr. Zhu suddenly became excited: "Mr. Qin, we will send the design data of the turbocharger to Huating Machinery Factory as soon as possible. I hope you can put it into production as soon as possible and install it on our engine for testing. If If the performance is improved compared to the current one, we will fully purchase the turbochargers produced by you!"
Qin Tao smiled: "We will quote the same price as the current turbocharger."
He can't say low price, after all, their machinery factory also has to make money, but it must be the same price as products with the same performance.
“Okay, thank you!”
“Mr. Qin, you also have an industry in the field of marine diesel engines. Do you want to expand your product line and produce diesel engines for ground vehicles?” Someone else suggested to Qin Tao.
Qin Tao smiled: "No, it's enough for us to become bigger and stronger in the field of shipbuilding. We don't want to develop comprehensively, lest our colleagues in the ground equipment industry scold us for not following martial ethics."
The technical industry has specializations. Marine diesel engines and automotive diesel engines are different. He can just make the same one himself, but he does not want to develop it comprehensively. If it continues to develop into a behemoth, there may be many problems.
Hearing what Qin Tao said, everyone laughed. Yes, you have to leave a mouthful of food for others.
The broken turbocharger began to be replaced and repaired, while Kong Laoer continued to be busy directing his men to level the land as soon as possible to provide more training venues.
“Lao Er, our equipment is getting more and more advanced.” Qin Tao said to Kong Lao Er.
"Of course, if we want to improve production efficiency, we must have advanced construction equipment. As long as the quality of domestic products is excellent, we will use domestic products and support domestic construction. However, we also have a lot of equipment that we cannot produce, such as Said, we need shield machines when digging tunnels, and we can only import them from abroad."
TBM? Qin Tao nodded: "We, the Mingzhou Group, can do this, just leave it to the machinery factory. But we can't let foreigners make our money. By the way, there is another project that I need you to prepare in the next few months."
"Of course, no problem, Mr. Qin, just give the order."
“In the Yangtze River, Nenjiang River, Songhua River and other river basin areas, some local warehouses are rented to store large quantities of sandbags, life jackets, rubber rafts and other equipment for flood control.”
Mingzhou Group has grown and developed, so it must make some contributions to society. It is already March and April, so we must prepare quickly.
Hearing what Qin Tao said, Kong Laoer suddenly reacted: "Is there going to be a flood?"
“Let’s prepare according to the scale of the flood in 1954.” Qin Tao said: “Be prepared. If there is a flood, then we can make some contributions to the country.”
Qin Tao cannot say with any certainty that there will be a flood now, otherwise he will become a prophet. Now he should be prepared to be prepared.
“Okay, Mr. Qin, don’t worry, we will complete this task as soon as possible.”
Zhao Ling was a little curious on the side. After Kong Laoer left, she whispered: "Brother Tao, how do you know?"
"Recently, I have seen many international meteorological experts saying that we should be careful about the El Niño phenomenon and be prepared in advance." Qin Tao said: "It's almost done here. Let's go back with dad?"
Wu Shengli inspected the training of the 63A tank there, gave some instructions and encouraged him. Now he is fine, so we just went home together.
"Damn it, are these people too shameless?" At this moment, an angry curse came from the Marine Corps.
Qin Tao was stunned for a moment. Could it be that he disliked the training because he didn't work hard enough? its not right! This is just the beginning, and the scolding words are a bit inappropriate.
“Tao Zi, let’s go back with me!” At this moment, Wu Shengli strode over and shouted to Qin Tao.
It seems like it’s not something here, it’s something else!
Xu Zhengyang had no room, so he got into the car they came from and followed them back together.
In the car, Wu Shengli introduced him angrily.
“I just received news that Gaoming Company proposed a proposal to cancel the civilian use of S-band at the World Radio Conference organized by ITU.”
S band? The first thing Qin Tao thought of was the phased array radar used on the Aegis battleship, but the World Radio Conference has nothing to do with it! They only manage civilian matters, not military matters.
What the **** is Gaoming Company?
"It is to obstruct our Beidou satellite." Zhao Ling said: "However, their proposal is just their wishful thinking. In this regard, we will resolutely resist. The World Radio Conference is not theirs."
At present, the world's satellite navigation system is only dominated by the American GPS. Although Lao Maozi also developed GLONASS, due to Lao Maozi's poor economy, this system has been in a state of abandonment for a long time. Lao Maozi's satellites The lifespan is too short and must be reissued in one or two years. As long as it is not reissued, the satellite network will not be able to cover it. Now, it is estimated that more than half of the satellites are in a state of neglect.
On the surface, GPS is divided into military and civilian uses. The accuracy of civilian uses is slightly lower, but it does not charge any fees. It is free and open. However, there are also many places to make money in free and open.
There is a complete and hidden industry chain behind GPS, including chip sales, signal terminals, patent licensing fees, navigation software, etc. Even though users do not spend money, the market size of GPS is in the hundreds of billions!
Take the authorization fee as an example. Regardless of any device, as long as it is equipped with GPS, it must be authorized. For example, for common mobile phones in later generations, major mobile phone manufacturers must pay the authorization fee in advance. Otherwise, the mobile phone cannot use GPS, even a mobile phone. We only charge one yuan, and more than one billion units are shipped around the world every year. This is an income of more than one billion yuan.
Another example is chips. Not everyone can produce GPS chips. Although the signal is free, profits can be added to the chips.
Later generations of navigation software, such as AutoNavi, Baidu and the like, no longer require money. However, the famous Kailide in the early days charged a fee. You cannot update the digital map without paying. Thinking about the rapid changes in urban construction, I don’t want to be dragged into the trap. You have to spend money to upgrade. Kaili De is just making money, so it naturally doesn't want to develop. As a result, it was eliminated by a lot of free navigation software.
As for Gaoming Company, it is a professional GPS terminal navigation company. They have agents, maintenance centers, sales and technical support personnel all over the world, and have various GPS patented technologies. The navigation equipment they produce is even better than its peers, especially As for aviation GPS navigation equipment, almost every three airplanes in the world are equipped with their company's products.
They proposed this, of course, to block the construction of the Beidou navigation system in the East and continue to monopolize the global positioning system. Monopoly will bring huge profits.
Mingzhou Group wants to produce ground receiving terminal chips for the Beidou navigation system. In other words, only for civilian use, Mingzhou Group and Gaoming Company are in a competitive relationship, and the other party wants to destroy Mingzhou Group's job!
After thinking about this clearly, Qin Tao's face became serious: "Yes, we must not let them succeed! Dad, let's go directly to the Aerospace Academy to find Mr. Sun."
“Well, the leaders of other units should go over and come up with countermeasures together. Beidou navigation is of great significance to our military construction, and we must not let the Yankees’ conspiracy succeed!”
Beidou navigation is not only for civilian use, but more importantly for military use. The military cannot do without satellites whether it is navigation or precision strikes. It is very dangerous to use GPS now. The signal may be cut off at any time, leaving advanced equipment If it completely fails, only its own satellite is the safest.
The military also attaches great importance to this project. Now, seeing that the satellite is about to be launched, and someone has played such a trick on it, it must quickly think of countermeasures.
Zhao Ling originally belonged to the Aerospace Academy, and now she is revisiting her old hometown. Qin Tao has also been here a few times. When she first came to see Beidou, the R&D staff had to move to a heated warehouse to work because the boiler in the office building broke down. , in such a difficult environment, the R&D personnel did not stop their work and developed the satellite with great difficulty. In the end, the Beidou navigation system became a global satellite navigation system, reflecting the confidence of a major country!
On the way, Qin Tao's mood was complicated. He suddenly thought of something: "If the S-band is cancelled, what will happen to the American satellites? Do they use different frequency bands from us?"
"This is due to technical reasons." Zhao Ling was able to explain to Qin Tao directly: "We use the principle of double star positioning, which is the simplest and cheapest. However, the disadvantage is that it not only requires downward movement, but also upward movement. The signal must be sent to the ground center for interpretation. Therefore, we use the L-band to upload the signal from the user to the satellite, with a frequency of 1610 to 1626.5MHz, which is the L-band. This is the same as the frequency band of Lao Maozi in the United States, but Our downlink signals from satellites to users use the S-band, with frequencies from 2483.5 to 2500MHz."
The technology is still not strong enough. If it comes to Beidou 2 or even Beidou 3, there will be no problem. They are all in the same frequency band.
However, there are also disputes within the frequency band. The frequency band used by Beidou is the same as that of Galileo, which resulted in protests in Europe. However, internationally, the general rule is that whoever takes advantage of it first, so you can use it if you use it. Well, who allowed Europeans to fight among themselves and Galileo to have difficulty giving birth? Moreover, it once cheated China. Even if you really mean to disgust them, it's normal.
At this time, after hearing Zhao Ling's words, Qin Tao finally understood, and his mind was thinking about countermeasures rapidly.
This protest is okay. After all, although the Beidou satellite has experienced twists and turns in history, it has always been successful. This does not require his participation, but since he has participated, more powerful means must be used!
Mingzhou Group is engaged in shipbuilding, and our goal is the stars and the sea! We not only have ideals, but we also have strength. We have a starship company.
Thinking of Starship Company, Qin Tao gained greater confidence.
Aerospace Academy, conference room.
“We need to contact China and other countries to win their support. In the aerospace field, we must not let the Americans have the final say!”
“That’s right, we must smash Gao Ming’s conspiracy!”
“I think we can unite them. If they propose to cancel the S-band, we will propose to cancel the L-band!”
The conference room was noisy. Mr. Sun was sitting on the podium with mixed emotions.
They are focused on their work, hoping to complete the project as soon as possible and send the motherland's first-generation navigation satellite into the sky. They will first meet the needs of the navy!
I just didn’t expect that difficulties are everywhere, not only in their work, but also internationally!
The use of the frequency band requires advance registration, usually before the satellite is launched. After all, no one uses this frequency band, it is just a process. Unexpectedly, Gaoming Company actually came to the bottom of the pot and did such a small trick!
What to do next?
His mind was in turmoil.
At this moment, another person walked in from outside. When he saw the appearance of those people clearly, he suddenly felt excited.
Mr. Qin, Mr. Qin is here! Mr. Qin will definitely have a good idea!
"Mr. Qin, come in quickly, please sit down. Do you have any countermeasures?" Mr. Sun was so anxious that he even ignored Wu Shengli next to Qin Tao.
"Yes, I have a plan." Qin Tao said: "Don't they just want to hinder the construction of our Beidou navigation system? They don't want us to have an easy time, and we don't want to make it easy for them!"
As soon as Qin Tao said these words, everyone present was stunned. What did Mr. Qin mean? Could it be that at the World Radio Conference, the L-band was requested to be cancelled? If this is cancelled, many countries will be offended. After all, this frequency band is not only used by navigation satellites, but other satellites are also used. In this way, we must not isolate ourselves?
“Mr. Qin, what are your plans? Tell me quickly!”
By the time Qin Tao finished speaking, everyone's eyes were bright.
Mr. Qin’s plan is really good! Thanks to the existence of Starship Company, a private company, we can help them with this.
“Okay, let’s see if the Yankees dare to persist!” Wu Shengli was very satisfied after hearing what his son-in-law said: “Our navy supports this plan!”
“Our Air Force also supports it! His grandma has to torment them like this!”
The meeting approved Qin Tao’s proposal on the spot.
That afternoon, Qin Tao took a special plane to Qiongzhou. He needed to go to Starship Company to arrange the project.
Every time he comes here, Starship Company will be completely different. But after this time, the rocket assembly shop has been built, and technicians wearing dustproof suits are working in an orderly manner.
“Mr. Qin, our first starship MK1 rocket is about to complete final assembly and will be launched into space this summer.” Max said: “We are finally taking a decisive step!”
“Are you sure?” Qin Tao said, “With so many engines connected in parallel, will they explode?”
Max took a deep breath: "It's possible."
