For warships, using electromagnetic guns has unique advantages. After all, warships have enough space. In the era of battleships, naval guns with a caliber of more than 400 mm could only be installed on battleships, any other land
The equipment is simply not available. Of course, Dora cannon is a special case.
The warship has enough capacity to accommodate a lot of things. Warships above 10,000 tons are more like a small city, with all kinds of equipment available. Now, the warship has electromagnetic guns and has enough space to accommodate various types of equipment.
Electronic equipment and the entire warship can also provide sufficient electricity for full-electric propulsion.
However, tanks are different. The space of the tank is small and every inch of land is valuable. If you install electromagnetic guns on the tank, how should its energy storage problem be solved?
Even if it is stacked batteries, these sixty-degree-degree batteries will occupy a considerable space. It may not be enough to occupy the entire engine compartment of the tank. Where can I have extra space for the generator?
Qin Zhenhua looked at the current device and couldn't help but ask his own questions.
"Yes, this is also what I proposed. It is necessary to develop a fully electric-driven tank." Liu Wei said from the side: "At present, the engines normally used on our tanks have reached 1,500 horsepower.
However, if these powers are converted into electrical energy, there will still be some loss. If this continues, it will be a very amazing level to be able to emit four gigajoules of energy in one hour.
If you drive an electromagnetic gun, even if the energy of an electromagnetic gun shell is only 40 megajoules, it is only the level of firing a hundred shells in an hour. However, there are many efficiency issues in it."
"For example, the energy converted into shells can only reach about 30% at present." Liu Wei continued: "In this way, the tanks do not understand where they are. Within an hour, they can fire fifty shells.
Each shell can only have about 30 trillion joules of energy, and this level is already amazing."
If it is a chemical shell, it has nothing to do with the engine, but this electromagnetic gun requires a lot of energy.
"So, we need a generator system with a more compact structure, and the power generation must reach about 2,000 kW." Liu Wei continued: "And the volume must be small, so it is more appropriate to take the gas turbine route, which can make
The tank's power system has the smallest volume, and at the same time, it can also leave some space for energy storage devices."
"The current energy storage devices are mainly supercapacitors. This kind of energy storage device can meet the needs of large current discharge, but it occupies a lot of space. Therefore, if you take the path of superconducting energy storage coils, it will be more developed.
Prospects, even if it is a laser weapon, it has already targeted the path of superconducting energy storage coils. In this regard, our domestic scientific research has the advantage."
Liu Wei began to introduce various high-end theories.
It is best to use a gas turbine to increase the power of the engine, because this thing can operate at high power and is small in size. However, the demand for fuel is higher. If the new generation of diesel engine invented by a machine manufacturer can achieve the goal.
, This kind of engine can also be used to generate electricity, but the power must be increased to 2,000 kW to meet the needs of electric tigers such as electromagnetic guns.
After all, the example he just gave was an example of a tank not moving. In fact, it is impossible for a tank to stay still on the battlefield, so the tank needs additional energy to move. Moreover, if the tank is tall and high,
If the electromagnetic armor is used, it will consume a lot of energy. In this way, the power of 2,000 kW of power generation is already the lowest, which also means that the power of the tank's engine may have to be increased to about 3,000 horsepower.
It can catch up with the power demand of some submarine engines.
For the first machine factory, the development of power systems will be a new challenge.
In addition to the engine, there must be an energy storage system, because the engine cannot directly provide enough power to the electromagnetic gun. It must be stored in advance and then fired a gun, use up all of it, and then stored.
The most important problem in the field of electromagnetic gun research that plagues the world is the energy storage system.
The United States is behind in this regard. They use conventional capacitance energy storage devices, with a capacity of 150 megajou. It cannot be stored in a supercapacitor, but it is connected in parallel by a large number of small capacitors.
, each "small" capacitor energy storage is 255 kJ and weighs 140 kilograms. The entire set of devices consists of 576 such small capacitors. After the complete set of devices, it becomes a monster weighing 90 tons, with a volume of
It's similar to a container.
This thing is definitely not possible to be placed on a tank, so there must be new ideas. Domestic research in the field of superconducting is also advanced. Using superconducting coils to store energy can better complete energy storage
The goal is now.
Liu Wei said a lot of professional data, and Qin Zhenhua shook his head repeatedly. He originally thought that the electromagnetic gun was close at hand. Who would have thought that it would take many years to equip the troops. In addition to the electromagnetic gun itself, those additional ones
Things are also very important, and there are many problems that need to be solved.
Hearing Qin Zhenhua's concern, Liu Wei nodded: "Yes, at present, it takes a lot of preparation to satisfy the use of electromagnetic guns on tanks. However, we believe that with the continuous development of domestic technology,
Various technologies will make breakthroughs. For example, if our electromagnetic guns can improve efficiency, from 30% to 50%, it can greatly reduce the pressure on the engine and energy storage system."
Improve efficiency, and reduce the demand for electricity, so as long as technology advances, all-electric tanks will still come step by step.
"We also know that the current third-generation tanks can take a long time to repair them continuously. If there is no revolutionary progress, then what is the meaning of our fourth-generation tank?" Liu Wei continued:
"If you want to do it, you can build tanks with the world's advanced level, and let other countries look up to you."
Fearing that Qin Zhenhua would lose confidence, Liu Wei quickly increased his investment for Qin Zhenhua. If we want to do it, we have to do the most advanced one in the world. We have technology and we have confidence. We want the whole world to see our military level!
