Chapter 2775: Add AIP system

Generally speaking, AIP system has three technical routes, namely closed gas cycle diesel engine, Stirling engine and fuel cell.
Anyway, conventional submarines are equipped with diesel engines. So, to directly modify diesel engines is the first solution that comes to mind. Diesel engines need to absorb oxygen in the air, so simply simulate them.
The exhaust gas discharged from the diesel engine is passed through a carbon dioxide absorber to absorb part of the carbon dioxide gas, and the unabsorbed part of the exhaust gas is added with an appropriate amount of oxygen to form an artificial atmosphere and supply it to the engine.
In this way, a large liquid oxygen tank needs to be hung to supply oxygen to the engine. When the liquid oxygen tank is used up, it will reach its maximum underwater navigation time.
How to simulate air and make the specific heat capacity of artificial air normal is a difficult problem.
The other is a Stirling engine that is a special externally heated continuous combustion engine, which is equivalent to adding a compartment specifically to accommodate this machine. The high-temperature gas burned from the outside is heated by the heating tube to heat the internal circulating working fluid to perform work. This kind of engine does not have much problem in principle. The defect is that it cannot produce too much power, so it can only maintain the submarine at low speed. As for the fuel cell, it is a space technology. It relies on the reaction of hydrogen and oxygen to directly generate electricity. The only by-product is water. This technological route is the highest end. Moreover, it requires not only liquid oxygen, but also liquid hydrogen.
It should be understood that the storage of liquid hydrogen is much more difficult than liquid oxygen, and the production of liquid hydrogen is also difficult. It consumes a lot of energy and is definitely more difficult than making liquid oxygen.
Liquid oxygen is separated as long as the air is liquefied. Liquid hydrogen can only be obtained by electrolysis of water.
Therefore, people in later generations continue to brag about what electric car is wrong, and hydrogen power is the final technical route. It simply does not consider the actual situation, let alone how dangerous the liquid hydrogen tank on the car is, just this kind of liquid hydrogen. In terms of the price, it must be at least twenty times that of gasoline, which consumes more energy.
The so-called hydrogen power is nothing new at all. The fuel cell solution in the AIP system of conventional submarines is actually the basic principle of this kind of hydrogen-powered vehicles. It's just that the oxygen in the air is used directly instead of liquid oxygen. As a result, its exchange membrane is easily blocked.
It is certainly not cost-effective on a hydrogen-powered vehicle, but it does not matter on a submarine. Military equipment will never put economy on the first requirement.
However, the problem is that the Ruby Design Bureau simply does not have this ability. They are responsible for the design. They need a large number of subordinate factories to provide supporting equipment. It can be said that there is no factory in Xiong Country. Those who produce this system, that is to say, they have no ability to join the AIP system at all.
The first question asked by President Qin stunned them.
"President Qin, if you feel that the submarine is dangerous when it is charging while floating, we have a solution to add anti-aircraft missiles to this type of submarine," Spasky said.
Qin Guan immediately shook his head: "The submarine is equipped with anti-aircraft missiles? Did you know that during the World War, Hans State navy submarines used anti-aircraft guns to deal with the tragedy of air planes?"
To say that the country with the richest experience in using submarines is definitely Hans. In that world war, Hans built a large number of submarines and became a pack of wolves on the Daxi Ocean.
However, the Allied aircraft became their biggest enemy. Later, they were whimsical, equipped with anti-aircraft guns on the deck guns, and planned to head-on. After discovering the aircraft, they did not dive and fired at the opponent. The result? A large number of planes that were called out directly sank to the bottom of the sea.
Submarines will never be able to confront aircraft. Using anti-aircraft missiles to deal with aircraft is definitely a mentally retarded behavior. You actually come up with such a plan to deal with it. How foolish is that?
Spasky stopped speaking, and for an instant, the entire conference room fell into a cold field.
"We believe that if there is a disagreement, there will be a solution." Boris also knows many people here. Seeing this, he came to the end: "Perhaps we can negotiate a solution that satisfies both parties. What?"
Are both satisfied? Yes indeed! A new solution suddenly appeared in Spasky’s mind: "Mr. Qin, you strongly demand this type of AIP system, but as far as we know, there is almost no mature and reliable such system in the world, and it is expensive. Fang’s technology is advanced, so do you have this technical capability?"
Qin nodded in view: "We are developing the Stirling engine ourselves."
Han must have this kind of AIP system. After all, Han has a long coastline. Nuclear submarines are too expensive to be equipped in large quantities. Many sea areas are relatively shallow and nuclear submarines cannot enter. Only conventional submarines can. Therefore, Han has been They are all studying the Stirling system. Although the power is not very strong, it is the least technically difficult and the easiest to implement.
"So, can we add an extra compartment with this kind of engine developed by you to become an AIP submarine?" Speyski said.
Qin Guan frowned, and his expression looked serious: "Our engine is top-secret, and there is absolutely no room for leaks. If you give this engine to you, even if you give you technical information, it will be leaking. ."
Qin Guan continued to have problems, so what should be the solution?
"Or, let the designers of Han State join in and design together?" Boris continued to talk to the mud: "In this way, the design of the AIP compartment is handed over to them, as long as their design is integrated into the entire submarine. Just go, isn't it?"
After speaking, he kept winking at Spassky, and Spasky could only nod his head: "Okay, we are behind the submarine, in the part of the power cabin. Let's add a cabin section. Let you design everything. In this way, you don’t have to worry about leaks, we just need to do a good job of coordination. However, this will increase the displacement, and the maximum underwater speed may be reduced." In order to get the order, Spasky is doing his best.
Qin nodded his opinion: "Well, we can consider sending our designers over to design together. We also have to supervise during construction. Sorry, this is not to worry about you, but there are certain countries, such as white The elephant country is aimed at us, and we must guard against it."
Spasky nodded. As long as Han Guo can place an order, everything can be discussed. Only by selling the products can we make money.
Qin Guan looked at Boris with satisfaction. He did a very good job this time. He successfully comprehended his own requirements. His own personnel joined in and participated in the design and manufacturing. Therefore, he could still fool others. , Can also intervene in the design of this submarine.
"I think this submarine has potential for improvement. For example, its propulsion system can use more advanced propellers." Qin Guan continued to ask.
