Chapter 402 $100 million deposit

  If your own is good, why buy someone else’s? It must be because my technology is not good enough!

  This is too obvious a truth.

  But now, can Qin Tao admit it directly?

  If the submarine technology of one's own side is not as good as Da Mao's, why doesn't the Pyramid country directly purchase from Da Mao? Anyway, now that the Red Empire is gone, if the Pyramid Country comes to purchase, Da Mao will definitely applaud and welcome it.

  However, if Qin Tao does not admit it, then he is denying the fact. After all, he has already bought it, and the goods arrived a few days ago.

"Mr. Mamish, your question is very good. In the past, our submarine technology was indeed inferior to that of Da Mao, so last year, we decided to purchase Kilo-class submarines from Da Mao, but now, We already have excellent submarine designers with advanced design concepts, so the performance of our upcoming submarines will be even more advanced.”

  Kilo-class submarine was bought last year, and our submarine technology breakthrough came after that!

   "As for whether it is advanced, you can ask Kwasha, he is the designer of the Kilo-class submarine, and he can answer your question, whether the technology of the submarine we are developing should be ahead of the Kilo-class."

Kwasha nodded: "In many fields, this submarine is more advanced. For example, the overall design, with a single hull in the front and double hulls in the rear, is the biggest innovation. It is a product that combines the advantages of the East and the West. As for the internal supporting facilities, there has also been great progress. For example, it uses a twelve-phase generator, which is the most advanced technology in Europe. The Kilo-class submarine is still the most common three-phase generator, the same Driven by the diesel engine, the electric energy generated by this twelve-phase generator is more than twice that of before."

The twelve-phase generator is definitely not four times that of a simple three-phase generator. After all, when the coil cuts the magnetic induction line, it will also be subjected to the ampere force, that is, the reaction force. The more phases, the greater the reaction force. However, It is no problem to double the efficiency of the generator.

"Since the performance of this submarine is so good, why do you continue to place an order for eight Kilo-class submarines?" Mamish unexpectedly did not agree with Qin Tao's point of view, even in front of his teacher Kvasha, Still had his question.

   While saying that they have caught up, they are still secretly placing orders. What's going on? Fool people?

A smile appeared on Qin Tao's face: "I think the news you got must be wrong. So far, we have no new submarine orders in China. I can guarantee this. This year's procurement expenses have been used up. The domestic Submarine procurement will have to wait until at least next year."

   Those eight submarines were designed to fool the old men, to let them eat dogs, to disappoint the Red Solmovo Shipyard, and then sell the submarine production equipment to himself at a low price. Qin Tao did not expect that this rumor would spread.

  He can’t say that he fooled the old man now, but he can say that the country will definitely not continue to purchase weapons and equipment this year, especially large items like submarines. You must have heard it wrong.

  Qin Tao's explanation is patient enough. If the other party still doesn't accept it, then Qin Tao doesn't want to continue to receive these guys, and he will go back where he came from.

  Fortunately, Mamish accepts as soon as he sees it. Since these questions have already been answered, they will no longer ask the bottom line.

   "Excuse me, do you have any questions?"

Hearing Qin Tao's question, Mamish thought for a while, and then said: "Mr. Qin, you said something about the Stirling engine at the defense exhibition last time. We are very interested in this kind of equipment. I don't know Can I see it with my own eyes?"

  Although there is an old submarine designer, there should be no major problems in design, but Mamish is still worried about some of Qin Tao's promises. After all, China does not have a single AIP submarine in service yet!

  How about this Stirling engine?

  Who knows if the performance will work?

   "We have one here, you come with us." Qin Tao said.

Speaking of the Stirling engine, the 711 Institute has been researching it after it was introduced in China, and the brother units are currently considering integrating this engine into the 039 submarine, and the third design office of the Mingzhou Group is also engaged in submarine design. Maozi's submarine designer had never seen this kind of engine before, so he couldn't design it, so Qin Tao coordinated one.

  Stirling engine is a closed-cycle power device that does not depend on air. It has two pistons connected together by a crankshaft. The working fluid enclosed in the pipeline between the two pistons is generally an inert gas.

The working principle is also very simple. The cylinder outside one of the pistons can be heated. In this way, the heated inert gas expands to drive the piston to reciprocate, and then the piston drives the crankshaft to rotate. At the same time, the inert gas enters another cylinder with cooling fins. The inside is cooled, then pushed back by the piston, heating continues, and the next cycle begins.

  In this way, the power can be continuously reciprocated.

   Judging from its principle, the fuel does not burn internally, so it is an external combustion engine just like a steam turbine. Moreover, it is not picky, no matter what is used for heating.

   On the submarine, of course, local materials are used, and diesel is directly used for heating.

  However, only diesel fuel cannot be burned and must have oxygen. Therefore, submarines with this power system need to add a liquid oxygen tank.

   However, in comparison, this method is still the safest.

  For example, fuel cells require liquid hydrogen in addition to liquid oxygen. Liquid hydrogen is not only difficult to produce, but also complicated to store.

  As for the closed-cycle diesel engine, not only liquid oxygen, but also special inert gas are required.

   In addition to fuel convenience, another feature is low noise.

  The hot-end cylinder of the Stirling engine can be heated all the time, and the combustion is continuous, so that it does not vibrate like a diesel engine and is very stable.

   However, although the theoretical efficiency of this engine is very good, it is not very good in practical application. The low thermal efficiency and low power have become the shortcomings that hinder its large-scale use.

   Of course, these weaknesses are not terrible, and can be improved through repeated research.

   At this time, the inspectors from the Pyramid Country followed the technicians from the third design department to a wide room, and a uniquely shaped engine was placed in the center.

  There are various complicated pipelines exposed on the outside, and the two huge cylinders are in a V-shaped layout, which looks very unique.

  The cold end does not use a simple heat sink, but uses a liquid heat dissipation method. Therefore, the cylinders on both sides look the same, and are covered with a layer of stainless steel-like material, which looks shiny.

"The biggest disadvantage of this kind of engine is its low power, so at present we can only adopt four parallel connections to jointly drive a generator, which can allow the submarine to achieve a speed of about four or five knots underwater and last for more than 20 days. "Qin Tao said: "In the future, the power of this kind of engine will gradually increase, which will bring a qualitative leap to the submarine, and even completely replace the diesel engine in the end."

If the power is large enough, then this kind of submarine does not need to carry a diesel engine anymore. It is enough to directly drive the submarine with a Stirling engine. In the state of the snorkel, it consumes the oxygen in the air, enters the water, and then consumes the oxygen it carries. liquid oxygen.

"There is another way." Krasnopolsky, who has not spoken much, said: "We can install an ultra-small nuclear reactor on the submarine, and use the heat of this reactor to heat the Stirling engine. In this way , the submarine has no need for oxygen and can sail underwater forever.”

  Krasnopolsky is a nuclear reactor designer after all, so no matter what the device is, he can think from the perspective of a nuclear reactor.

   Such a design is possible, but it feels like farting and taking off your pants. If the nuclear reactor can be used to heat the Stirling engine, why not use the nuclear reactor to directly drive the steam turbine?

  However, the size of the nuclear reactor required by the two is different. Krasnopolsky's vision may really be realized.

  Mamish nodded again and again: "Yes, that's right, is this engine produced by you yourself? Can you make it run?"

   It is not enough to just look at the static display, Mamish also wants to see this kind of engine running, and it has to be made in China, so that it is practical.

   "Of course, let's start this machine."

  The technicians started to operate.

  The machine made a soft sound similar to that of a motor, and the shaft began to rotate. There was hardly any vibration in the externally connected pipelines.

   "That's awesome, this engine is a perfect match for the submarine!"

   "So, are you going to purchase this kind of submarine with an AIP cabin?" Qin Tao asked again.

   I’ve seen it too, maybe I’ll give you an answer!

   "Mr. Qin, we want a detailed bidding letter, clearly marking the internal structure and parameters of various equipment, for our reference, we may choose this product." Mamish said.

  Qin Tao shook his head: "Impossible."

impossible?

"Our submarine is top secret. Everything that can be announced has already been announced at the defense exhibition." Qin Tao said: "What you want to take back for reference now is the manual you took back last time. Unless you Only by placing a deposit now can we provide more detailed product information.”

To the old bus, Qin Tao can be very frank, not only the price is right, but also there is no problem with credit. However, for the pyramid country, that is to pay with one hand and deliver with one hand. The other party does not spend a penny, but also wants to get some good things ,That is impossible.

  Qin Tao's words are categorical.

   "So, how much is the deposit?" Mamish asked.

   "One hundred million."

  If you want information, bring 100 million first. Even if these people don’t buy it in the end, Mingzhou Group won’t lose much.

   Mamish frowned. Such a high deposit is unacceptable!

   "Mr. Qin, in the current international arms market, the deposit is at most 20 percent. The deposit you are asking for is a bit high." Mamish said.

"Because there are a lot of our secrets in it." Qin Tao said: "This is an advanced equipment that surpasses the performance of Kilo-class submarines. Once its detailed design is leaked, our competitors will get ideas for improvement. It will cause us great loss."

  Qin Tao spoke confidently, we gave you the design drawings, who knows what you will do? What if you go to the Germans to bargain with the detailed information?

   "Mr. Qin, this kind of transaction is very unfriendly to us. We can only know whether it is suitable for us if we get the detailed information." Mamish said.

Qin Tao smiled: "For you, as long as you have the current technical data, it is not useful to give you detailed information. Looking around the world, there is no conventional diesel-electric submarine better than ours. , we can guarantee that after the submarine is manufactured, if the performance does not meet these data, then a full refund will be given.”

   This is the only thing Qin Tao can guarantee. We have the confidence to say that the speed can be as many knots as possible, and the decibels of the noise can be as many as the decibels. Others, you don’t have to worry about it.

   "However, when we purchase weapons and equipment from the United States, we have never encountered such harsh contract terms." An officer next to Mamish said.

   "That's right, then you can also purchase from the United States, why come to us?"

   One sentence choked the other party back.

The weapons of the United States are very advanced, and those that appear in the international arms market are even more sought-after. For example, the F-16 fighter jet is much cheaper than the Mirage 2000, and its performance is much higher. Even the second-hand goods eliminated by many countries have become popular. cake.

  However, in terms of submarines, the United States really has nothing to offer.

  The reason is also very simple, the United States does not produce conventional diesel-electric submarines.

  When the nuclear submarine technology matured, the United States fell in love with this kind of submarine that can have unlimited endurance underwater. Therefore, all their conventional submarines were eliminated, and all underwater were nuclear submarines.

  This also means that the United States has lost the design and construction capabilities of conventional submarines.

   Many of the weapons of the Pyramid country are purchased from the United States, but in terms of submarines, they really do not have this shortcut.

   What's next?

  British, French? The prices are ridiculously expensive! German? Even if the German 209 submarine is an evergreen tree in the international submarine market, the 209 submarine does not have the performance of the current Mingzhou Group's submarine.

   For all submarine captains, they wish their submarine could stay underwater all the time, even if the air pipe is not exposed, this is the safest way.

  However, conventional submarines can only rely on batteries underwater. After a period of time, they have to float up to the snorkel state and turn on the diesel engine to charge. This time is also the most dangerous.

Although all countries are researching and developing AIP technology, none of them have been put into practical use. The foreign trade submarine of Mingzhou Group in front of us is the first AIP device equipped with a submarine, which can allow conventional power submarines to stay underwater for more than 20 days. , which is a pretty impressive performance too.

   It is precisely because of this kind of performance that the Pyramid Kingdom decided to come to the East to purchase, but it was unexpected that the other party's conditions would be so harsh!

  They originally only planned to pay a few million deposits, and then take the information back and study it in detail. As for leaking it to competitors, they haven't thought about it yet, but now that the other party has offered a condition, should they agree?

   "Boss Qin, we came here with sincerity, please give us a favorable condition." Mamish said.

   "We also come to receive you with sincerity. I take care of everything and spare time to accompany you. Isn't it sincere enough?"

  Qin Tao was very disdainful.

  These guys are so good at getting cheap! It is enough to give them face by coming to accompany them on the tour.

   "I don't know this kind of submarine, has your navy ordered it?" asked an officer from the Pyramid country.

   "Everyone, this is our military secret." Qin Tao said, "However, since you ask, I can also tell you that in our country, its number is 039B."

  Anyway, bragging and no need to pay taxes, Qin Tao's random nonsense is not a leak of military secrets, and the other party can't ask for proof. If he goes to the navy to ask for proof, the navy will definitely tell them, no comment!

   Domestic submarines have been used in large quantities since 033, to the research and development of 035 submarines, and now, the first 039 boat has just been built, which can be regarded as a rough road.

  At the same time, the random flowers gradually become charming. Although 039 is an advanced submarine in China, there are also different models, and the displacement between the front and rear can even be half. It has to make people wonder whether the number 039 is still used in order to avoid stimulating potential opponents. In fact, something happened earlier. a great change.

This submarine of the Mingzhou Group has not entered the navy's sequence at all. However, Qin Tao still calls it 039B. Maybe he can really get this number after he arrives. If he changes the hat of the command tower, it will become 039C.

  In short, their submarine is much stronger than the 039 submarine that the Navy is currently looking forward to.

   Mamish and others seem to be making up their minds.

  Qin Tao didn't bother them, and watched them chatting quickly. After ten minutes, Mamish finally spoke.

   "Boss Qin, we are willing to pay 100 million U.S. dollars to obtain its detailed information. After we officially start construction, this money should be converted into procurement funds, right?"

  If the time comes, Qin Tao says that the money is for materials, then they should cry.

   "Of course, I've said it all, this is a deposit. It seems that you plan to purchase 200 million AIP submarines?"

  Since you want to buy it, you must buy the most suitable one. The performance of this kind of AIP submarine is the closest to that of a nuclear submarine.

  Now this process must be followed. This kind of arms sales cannot be decided by a few people. They will go back with the materials, and then go through various procedures and procedures in the country before they can continue.

  However, with a deposit of 100 million U.S. dollars, the contract is complete. If the other party refuses in the end, the deposit of 100 million U.S. dollars will never be refunded.

(I checked on purpose. In English, deposit and deposit are the same word, so readers don’t have to worry about it. The language of foreigners is not rich, and there are not so many twists and turns. Anyway, the protagonist said it, and the pronunciation is correct. That’s fine. I suddenly remembered that there is a novel where the main character eavesdrops on someone’s conversation, and then realizes that it’s a woman and not a man!)

This project has come to this point for the time being. Originally, Qin Tao was still worried about the production equipment such as plate rolling machines. Unexpectedly, these Pyramid people who are meticulous in some aspects and very nervous in some aspects have never thought about Mingzhou Group at all. Do you have the strength to produce submarines?

  For them, this matter has come to an end.

   "Mr. Qin, I wonder if you are familiar with the aviation department?" Mamish continued to ask, which made Qin Tao curious. These people want to see the aviation department?

  K-8 trainer aircraft, the complete production line was exported to the Pyramid country, but that was already in the late 1990s. The current Pyramid country military has really no relationship with the domestic aviation sector.

   "Excuse me, what other plans do you have?"

  Qin Tao is a little familiar, he can take them to have a look, but, the domestic F7F8, I guess the other party doesn't like it either! There is no possibility of exporting the J-10 and J-11. What are these people doing here?

   Just when Qin Tao was surprised, the other party said: "We heard about your J-31A project, so we want to go and inspect it in person. If it is suitable, we also have the idea to invest in it."

  Nima, it’s this one? Qin Tao was a little surprised, but also a little funny, how could he forget this fighter? All ideas are my own!

In Qin Tao's original plan, Anxi Kingdom would definitely win over. This is a big financial backer. Although Lao Ba is also a potential customer, Lao Ba is poor. If he really invests in it, Lao Ba will not invest in such an expensive fighter. Must be equipped.

   As for other users, Qin Tao hasn't considered them yet. He is not surprised that they are similar to Dassault's taking advantage of them.

  Now, unexpectedly, Pyramid Kingdom is also interested in this project!

   "I know the person in charge of this project, and I can take you there. How much do you plan to invest?"

  Qin Tao has to ask clearly first, if the other party intends to invest millions or tens of millions, then forget it, it is not worth leading the way by himself, if it invests hundreds of millions of dollars, then it is okay.

   “We plan to spend $100 million,” Mamish said.

  Anyway, if you come here to order a submarine, the deposit is 100 million, and if you order two, the total price is 400 million. Therefore, they invested 100 million in the J-31A plan, which doesn't seem to be much.

  However, if he thinks about the financial situation of the Pyramid country, Qin Tao has more thoughts: "Are you sure you want to invest 100 million US dollars? How do you plan to pay this money?"

"Our current economic situation is not good, but we really want to support your plan, so we want to ask your bank to give us a loan to invest in this project, and we will pay back slowly in the future ’” Mamish said.

  Qin Tao almost laughed out of anger, okay, is this a white wolf with empty gloves?

"If that's your plan, then there's no need to go." Qin Tao refused bluntly: "If the bank borrows money, why doesn't our J31A R&D team directly seek a bank loan? Why bother to go through the process?" This procedure for you? When the research and development is completed and the fighter plane is sold, you can repay the loan. You pay it slowly, what are you going to use to repay it?"
