MTL - Warship of Great Power-Chapter 696 Cancel the S-band? Watch the Mingzhou Group's counterattack!

   "What's going on?" Zhu Lao ran over quickly, because he only had one arm, and during the running, he almost fell several times.

   "Mr. Zhu, don't worry. Slow down." Qin Tao hurriedly supported Mr. Zhu: "The smoke is gone, there should be no big problem."

   Only then did Mr. Zhu stop running, but he was still walking very fast. At this time, the tankers had finished extinguishing the fire and skillfully opened the rear engine compartment cover.

The armor on the front of the tank is thick and must withstand the attacks of various anti-tank ammunition, but the armor on the rear is very weak, similar to the steel plate of an ordinary armored vehicle. At the same time, the armor on the rear can also be opened, which is convenient for outdoor use Under the circumstances, the engine is hoisted as a whole.

  After opening it, you can see the place where the fire is on. After seeing it clearly, several people are very helpless.

   "The turbocharger leaked oil, and the entire turbocharger had to be replaced. Fortunately, it was discovered in time and no other places were hurt."

Modern tank diesel engines all use exhaust gas turbocharging, that is, the exhaust gas from the engine exhaust pipe is gathered to blow the turbine blades to rotate at a speed of tens of thousands of revolutions, and then drive the blades on the other side to boost the engine. Into the air. Compared with the previous supercharger that needs to be driven by the crankshaft wheel, this method does not need to consume extra power, and it uses exhaust gas purely, so it is very popular among engine engineers.

  The exhaust gas from the engine is also very hot, so if it runs at full power for a long time, the entire turbocharger will turn red, and if it leaks oil, it will directly cause a raging fire.

   Fortunately, it is only a rehearsal for the military parade now, and there is no need to drive too fast, so there is only smoke, and there is no direct fire. This is already a blessing in misfortune.

   "Change the turbocharger." Zhu Lao said: "The life of our turbocharger needs to be further reduced, and it should be set at 800 hours for the time being."

   "What, 800 hours?" Qin Tao was a little shocked: "Why? The turbocharger of a car can last hundreds of thousands of kilometers. Your tank is too old, right?"

When it comes to turbocharging, many people will sneer, saying that the life span is short. In fact, as long as it is maintained normally, the turbocharged engine can run hundreds of thousands of kilometers. It is no problem for normal household use until it is scrapped. In the 1990s , Steyr trucks are already equipped with turbochargers as standard, and they have a long service life.

  Even if Qin Tao is a shipbuilder, he knows the parts of the vehicle. He was shocked to hear that it only lasted 800 hours.

"How can a tank engine compare 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 life span 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 really lags behind. During the original test, the lifespan of 1,000 hours was set , now it seems that it has 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 formerly the Huating No. 2 Water Pump Factory, a factory acquired by Mingzhou Group in the early stage, and later became a supporting factory for the shipbuilding industry, from water jet propellers to variable pitch propellers, submarine seven-bladed large skewed propellers , Up to now, the lift fans and other components prepared for vertical take-off and landing fighters are all products of their factory.

  Since there are difficulties in the manufacture of this turbocharger, of course Mingzhou Group can help.

   Zhu Lao’s eyes suddenly lit up, yes, why didn’t I think of asking the airline company for help?

  The development of the 150HB engine was not easy. They thought of various methods and developed various new production processes to solve technical problems one by one. Some problems were solved, and some problems remained unsolved.

For a tank engine, the advanced high-performance turbocharger is the main factor for its strong power output. The more powerful the supercharger, the greater the output power of the engine. However, the greater the boost ratio of the supercharger, This means that its manufacture will be more complicated.

In terms of advanced tank power systems, the military workers have also followed one step at a time, and have been catching up to the world's most advanced level. Yes, it is the world's most advanced level. After that, domestic tank diesel engines have already caught up and surpassed German tanks. Diesel engines rank among the first echelon.

  Britain, once the most arrogant, has stagnated for a long time after developing the 1,200-horsepower diesel engine used on the Challenger tank, so that in later generations, tanks for export need to be equipped with European power packs.

The maverick French, knowing that it is difficult for them to deal with the advanced tank diesel engine, simply started from scratch, using a gas turbine as a turbocharger for the diesel engine, and made an alternative ultra-high-pressure diesel engine. Based on the eight-cylinder engine A power output of 1,500 horsepower was achieved. However, whether it is used or maintained, this thing is very expensive. Therefore, when this kind of tank is exported, it is also replaced with a European power pack.

The European power pack is Germany's most advanced tank diesel engine. On the Leopard-2 tank, Germany produced the MB873 engine. This engine was the first to achieve a power output of 1,500 horsepower, but it used the method of increasing the speed. While making it meet the power standard, it also generates a lot of heat, and more than 200 horsepower will be consumed for heat dissipation.

  Later, the Germans came up with a reduced bore and stroke MB883 engine, coupled with the advanced Lenk gearbox, it became a European power pack.

  Technically speaking, it is indeed more advanced than the 150HB used in the 99 tanks. Even if the domestically produced engine is upgraded, it can still output the same 1,500 horsepower. There is still a gap in terms of life and fuel consumption.

However, while the development of the West has stagnated, the tank designers of the motherland still have not given up their research. When they developed plateau tanks, they started from scratch and used an 8-cylinder 132 engine. The region can achieve an output of 1,000 horsepower. If it is increased to 12 cylinders, it can reach 1,500 horsepower. Moreover, because of its small displacement, its volume is also small, which will make the layout of the tank easier .

  Although he is engaged in the shipbuilding industry, Qin Tao also understands these basic knowledge, and his own tank technology will continue to develop, and eventually become 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 immediately 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 the performance is improved compared with the current one, then 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 talk about low prices, after all, their machinery factory also has to make money, but the same price as products with the same performance is a must.

   "Okay, thanks!"

   "Mr. Qin, you also have an industry in the field of marine diesel engines. Do you want to expand your product line to produce diesel engines for ground vehicles?" Another person proposed to Qin Tao.

  Qin Tao smiled: "No, it's enough for us to be bigger and stronger in the shipbuilding field, but we don't want to develop in an all-round way, so as to avoid the colleagues who are engaged in ground equipment scolding us for not being good at martial arts."

  There is a specialization in the technical industry. Marine diesel engines are different from vehicle diesel engines. If it continues to develop into a behemoth, there may be many problems.

  Hearing what Qin Tao said, everyone laughed along with him. That's right, we 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 subordinates to level the land as soon as possible and provide more training grounds.

   "Second brother, our equipment is getting more and more advanced." Qin Tao said to Kong Laoer.

"Of course, if we want to improve production efficiency, we must have advanced construction equipment. As long as the quality of domestic production is excellent, we will use domestic production and support domestic construction. However, we also have a lot of equipment that cannot be produced, such as Said, we need shield machines when digging tunnels, and this can only be imported from abroad.”

  Shield machine? Qin Tao nodded: "Our Mingzhou Group can do this, just leave it to the machinery factory. We can't let foreigners earn our money. By the way, there is another project that I need you to prepare in the last few months."

   "Of course no problem, Mr. Qin, just give the order."

   "In the entire basin of the Yangtze River, Nen River, and Songhua River, some local warehouses are leased to store a large number of sandbags, life jackets, rubber rafts and other equipment for flood control."

  Mingzhou Group has developed and grown, so it has to make some contributions to the society. It is already March and April, so we have to prepare quickly.

  Hearing what Qin Tao said, Kong Lao Er suddenly reacted: "Is there going to be a flood?"

   "Let's prepare according to the scale of the flood in 54 years." Qin Tao said: "Be prepared. If there is a flood, then we can make some contributions to the country."

  Qin Tao can’t say with certainty that there will be a flood now, otherwise he will become the emperor of prophecy, so make some preparations now to be prepared.

   "Okay, Mr. Qin, don't worry, we will complete this task as soon as possible."

  Zhao Ling was a little curious at the side, and after Kong Laoer left, she whispered, "Brother Tao, how do you know?"

   "Recently, I saw a lot of international meteorological experts saying that El Niño phenomenon, we still have to be on guard and make preparations in advance." Qin Tao said: "It's almost here, let's go back with Dad?"

  Wu Shengli inspected the training of the 63A tank over there, gave some instructions and encouraged him, and now he is fine, so we happened to go home together.

   "Damn it, aren't these people too shameless?" At this moment, there was a curse from the Marine Corps.

  Qin Tao was stunned for a moment. Could it be that he disliked that the training was not serious enough? its not right! This is just the beginning, and what's more, the words of scolding are a little inappropriate.

   "Taozi, go, come back with me!" At this moment, Wu Shengli had strode over and shouted to Qin Tao.

   It seems that this is not the thing here, but something else!

  Qin Tao looked at the father-in-law's livid face very curiously. He didn't know what had stimulated him into this state. He followed Wu Shengli into the car, and Zhao Ling also sat in the front passenger seat.

  Xu Zhengyang had nowhere to go, so he got into the car they came from and followed them back.

  In the car, Wu Shengli introduced it angrily.

   "Just got the news that Gaoming proposed a proposal to cancel the private use of the S-band at the World Radio Conference organized by the ITU."

  S-band? The first thing Qin Tao thought of was the phased array radar used on the Aegis battleship, but this World Radio Conference has nothing to do with it! They are only for civilian use, not military use.

  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 it. The World Radio Conference is not what they decide."

At present, the world's satellite navigation system is only dominated by the GPS of the United States. Although Lao Maozi also developed GLONASS, but because Lao Maozi's economy is not good, this system has been abandoned for a long time. Lao Maozi's satellite The lifespan is too short, and it will have to 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 abandonment.

   On the surface, GPS is divided into military and civilian use. The accuracy of civilian use is slightly lower, but there is no charge, and it is free and open. However, there are many places to make money in free open.

  There is a complete and hidden industrial chain behind GPS, including chip sales, signal terminals, patent licensing fees, navigation software, etc. Regardless of whether users spend money, the market size of GPS is hundreds of billions!

Take the authorization fee as an example, no matter what kind of device, as long as GPS is installed, it must be authorized. For example, for common mobile phones in the future, all major mobile phone manufacturers have to pay the authorization fee in advance, otherwise the mobile phone cannot use GPS, even a mobile phone Only one yuan is charged, and more than one billion units are shipped worldwide every year, which is more than one billion in revenue.

  Another example is chips. Not everyone can produce GPS chips. Although the signal is free, it is completely possible to superimpose profits on the chip.

Later generations of navigation software, such as AutoNavi and Baidu, do not need to spend money. However, the well-known Kay Rucker in the early days charged a fee, and the digital map cannot be updated without paying. You have to spend money to upgrade. Kay Rucker is making money, so naturally it 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, repair centers, sales and technical support personnel all over the world, and have various GPS patented technologies. The navigation equipment they produce is even more advanced in the industry, especially Aviation GPS navigation equipment, almost one out of every three aircraft in the world is equipped with their company's products.

  They proposed this, of course, to stop the construction of the Beidou navigation system in the East, and continue to monopolize the global positioning system, which will bring huge profits.

  Mingzhou Group is going to produce ground receiving terminal chips for the Beidou navigation system. That is to say, only for civilian use, Mingzhou Group and Gaoming Company are in a competitive relationship, and the other party wants to smash Mingzhou Group's job!

  After thinking about this point, Qin Tao's face became serious: "That's right, 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 have passed, and they will work together to figure out countermeasures. Beidou navigation is of great significance to our army building, and the Yankee's conspiracy must not be allowed to succeed!"

Beidou navigation is not only for civilian use, but more importantly for military use. Whether it is navigation or precision strike, the military cannot do without satellites. Now the use of GPS is very dangerous, and the signal may be cut off at any time. Advanced equipment Complete failure, only your 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 people have played such a trick, they must quickly think of countermeasures.

Zhao Ling originally belonged to the Academy of Aerospace Sciences, and now she is revisiting her old place, and Qin Tao has also been here a few times. When he first came to see Beidou, the R&D personnel had to move to work in a heated warehouse because the boiler in the office building was broken. , In such a difficult environment, the R & D personnel did not stop their work and worked hard to develop the satellite. In the end, the Beidou navigation system became a global satellite navigation system, reflecting the confidence of a big country!

   On the way, Qin Tao was in a complicated mood. He suddenly thought of something: "If the S-band is cancelled, what will happen to the American satellites? Could it be that they use a different frequency band from ours?"

"This is due to technical reasons." Zhao Ling was able to explain to Qin Tao directly: "We use the principle of dual-star positioning, which is the simplest and cheapest, but the disadvantage is that not only the downlink, but also the uplink The signal has to be sent to the ground center for calculation. Therefore, we use the L-band to upload signals from the user to the satellite, and the frequency is 1610 to 1626.5MHz, which is the L-band. This is the same as the frequency band of the old Maozi in the United States, but We use the S-band for the downlink signal from the satellite to the user, with a frequency of 2483.5 to 2500MHz."

   The technology is still not strong enough. If it is Beidou-2 or even Beidou-3, then there will be no such problem, and they are all in the same frequency band.

However, within the frequency band, there are also disputes. The frequency band used by Beidou is the same as that used by Galileo, which resulted in protests in Europe. However, in the international arena, the prevailing rule is whoever occupies it first, so if you use it, use it. Now, who made the Europeans fight among themselves, and Galileo had a difficult delivery? Moreover, it once cheated China. Even if you really want to disgust them, it's normal.

   At this time, after hearing Zhao Ling's words, Qin Tao finally understood, and his mind was rapidly thinking about countermeasures.

  This protest is okay. After all, Beidou satellites have been successful in history despite their twists and turns. This is okay without his participation, but since he has participated, there must be more powerful means!

  Mingzhou Group is engaged in shipbuilding, our goal is the sea of ​​stars! We not only have ideals, but also strength, we have Starship Company.

   Thinking of Starship Company, Qin Tao has greater confidence.

  Space Academy, meeting room.

   "We need to contact Da Mao and other countries to win their support. In the field of aerospace, the Americans must never have the final say!"

   "That's right, we must smash Gao Ming's conspiracy!"

   "I think we can take them into the army. They propose to cancel the S-band, so we propose to cancel the L-band!"

   There was a lot of noise in the conference room, and Elder Sun was sitting on the rostrum, feeling complicated.

  They are all 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.

   I just didn't expect that the difficulties are everywhere, not only in their work, but also in the world!

  The use of the frequency band needs to be reported in advance, usually before the satellite launch. After all, this frequency band is not used by anyone, and it is just a process. Unexpectedly, Gaoming Company actually came to the bottom to engage in such a small trick!

   What to do next?

   His mind was buzzing.

   At this moment, people came in again. When he saw the appearance of those people clearly, he suddenly felt excited.

  President Qin, President Qin is here! Mr. Qin will definitely have a good idea!

   "Mr. Qin, come in quickly and sit down, please. Do you have any countermeasures?" Elder Sun was so eager that he even ignored Wu Shengli who was next to Qin Tao.

   "That's right, I have a plan." Qin Tao said, "Don't they just want to obstruct the construction of our Beidou navigation system? They don't want us to have an easy time, and let's not make it easy for them!"

  When Qin Tao said this, everyone present was stunned. What does Mr. Qin mean by this? Could it be that the L-band was requested to be canceled at the World Radio Conference? If this is cancelled, it will offend many countries. After all, this frequency band is not only used by navigation satellites, but also by other satellites. So you can’t isolate yourself?

   "Boss Qin, what plan do you have? Say it!"

   After Qin Tao finished speaking, everyone's eyes lit up.

   President Qin's plan is really good! Thanks to the existence of Starship Corporation, a private company, we can help them with this.

   "Okay, let's see if the Yankees dare to continue!" After hearing what his son-in-law said, Wu Shengli was very satisfied: "Our navy supports this plan!"

   "Our air force also supports it! His grandma's, they have to torment them like this!"

  The meeting passed Qin Tao's proposal on the spot.

  That afternoon, Qin Tao took a special plane to win Qiongzhou, and he needed to go to Starship Company to arrange this project.

  Every time he comes, Starship will change a lot, but after this time, the rocket assembly workshop has been built, and technicians in dustproof suits are working in an orderly manner.

   "Mr. Qin, our first Starship MK1 rocket is about to finish assembly, and it will be ready to launch this summer." Max said, "We are finally going to take a decisive step!"

   "Are you sure?" Qin Tao said, "With so many engines connected in parallel, will there be an explosion?"

   Max took a deep breath: "It's possible."
