Super military empire

"The hydraulic system does account for a lot of cost. And in our current situation, I don’t think it is necessary to design six pairs of road wheels. After many simulations and analyses, we found that according to our current design, the entire The weight of the tank has reached 61 tons. Six pairs of road wheels bear these weights, which makes the weight of each road wheel relatively high. This has caused a great burden on the hydraulic system, especially the suspension... "As the person in charge of the hydraulic system, Shi Chuanxiang does not hope that the technology that they have put in so many years of hard work will eventually become useless.

The Longwei tanks all use hydraulic systems, and the Republic uses them themselves. They will not be exported. Some are not justified.

Six pairs of road wheels, this was brought up by Liu Yijiu when he gambled with 617.

Moreover, this is the load mode used when the weight exceeds a certain range.

With a 38-ton domestic tank and five road wheels, the average base weight of each road wheel is only 3.8 tons. Even if the friction during the movement is calculated, it will not be too high.

The weight of 61 tons is shared by six pairs of tanks. Each wheel bears a basis weight of more than five tons. In addition to the friction and kinetic energy during travel, the weight of each wheel exceeds ten tons. What's more, the six-wheel plan The top speed reached 70 kilometers per hour, which is much higher than Type 59 and ****.

"Indeed, we think that perhaps more road wheels with small and medium diameters may be used instead of six pairs of large diameters. Large mass road wheels are more suitable." When Jiang Ming said this, he dared not stare at Liu Yijiu's eyes.

If you change from six pairs of road wheels to 7 pairs of road wheels, this will be a very big project.

The site had to be redesigned, and even the layout of the entire tank had to be modified.

Liu Yijiu himself proposed to design and manufacture a tank with six pairs of road wheels. Although they were very enthusiastic about this project at the beginning, they discovered the problem when the sample was produced. After simulation, they found that the tonnage was too large. The large-diameter road wheels bear greater gravity, which is a big test for the suspension system and the transmission system.

Even during the subsequent maintenance, the physical exertion of the soldiers is relatively large.

"Are there test data?" Liu Yijiu frowned.

He didn't say that six pairs of road wheels are necessary. As long as it is appropriate, it is not a problem to use how many pairs of road wheels.

With the improvement of technology, the performance of tanks will no longer depend on thicker armor and stronger offensive power to distinguish between heavy and light.If all the armor is replaced by graphene combined with carbon fiber, and the tank gun part is replaced with a lighter material, this will reduce the weight of the entire tank to less than 35 tons.

Or, there is no need for tank guns at all, the tanks all carry various precision guided missiles...

However, such a cost is even more unbearable by any country.

These methods can only be adopted when the technology develops in the future and the cost of various materials is reduced.

"Yes, I bring them all. I was just about to report to you and propose amendments..." Jiang Ming heard Liu Yijiu's words, and immediately took out a document from the table in front of him, with only five or six pages. However, the data on these five or six pages was obtained with hundreds of millions of funds.

Liu Yijiu didn't say anything. He took the file and looked at the various data on it.

The data in the file is not only the data of a certain scheme, but is compared with the data under the load of six pairs of road wheels. The differences between the various data and the impact on the tank are all clear at a glance.

The final result of the document completely proves that when the 7 teams of medium-diameter road wheels bear the weight of the entire tank of 61 tons, the speed of the tank can be faster, and the performance of the hydraulic suspension system is much lower.

The retrofit design plan attached later does not have complete drawings. It is just a list of some configurations. The entire design team feels that the current designs are still adopted, but the chassis design is modified, the road wheels are changed, and the suspension system and shock absorption are carried out accordingly. The technical adjustment of the system will do.

It is also very clear.

"Or, let's reduce this configuration a bit to achieve the performance of Longwei, and redesign a heavy tank?" Jiang Ming saw Liu Yijiu staring at the file silently without speaking, the whole person It seemed very serious, which caused a lot of pressure on them.

The others also stared at Liu Yijiu nervously.

Liu Yijiu is authoritative in this regard. The overall design is based on Liu Yijiu’s design ideas, and he has been staring at many technologies.

His influence on the entire tank design scheme is very large.

"Does everyone mean this?" Liu Yijiu glanced around, staring at him as if waiting for his own reply.

Everyone nodded sharply.

For design, you must choose the best design.

The six pairs of road wheels are not suitable, and the strength requirements for road wheels are very high. It has been proved that there are better options. Naturally, there is no need to waste too much time on them, right?

"At present, if the design is modified or the site is redesigned, the time is too late. Anyway, under the current circumstances, our design scheme is too costly. Even if the military has too much equipment, there will not be too much quantity. After the six-round plan design is finalized, the focus of our entire team's work can be devoted to the modification design." Liu Yijiu did not emphasize that six pairs of road wheels must be used.

For him, as long as the effect can be achieved, even with two pairs of road wheels, there is no problem.

In this age when the tank is heavier and more advanced in performance, the Republic needs to use six pairs of heavy tanks with road wheels to cope with the threat of the huge armored cluster of the Northern Soviet Union.

"Don't we still have half a year?" Just do it, this is the style of the Ninth Academy.

"In half a year, can we design a mature tank chassis?" Liu Yijiu smiled bitterly, and asked Qian Dayong, "Most of the technologies used in this tank are related to Longwei tanks and related technologies. The technology is upgraded, only the chassis, how long did it take us to design it? Even now, there are still some minor problems!"

The chassis is the key to the entire tank.

This is what the Ninth Institute lacks.

The Ninth Institute has been designing the chassis since the late 1970s, and almost ten years have passed since it only produced a barely usable chassis.

"It turns out that we don't have this technical accumulation. After so many years of design and experience accumulation, we also have a relatively rich design experience. Old Zhao, redesigning the chassis, there is no big problem, right?" Qian Dayong was eager for their tanks. Partitions have more designs out.

What he said is indeed correct. Over the past few decades, the Ninth Academy has invested a lot of experience in this respect regardless of cost.

Zhao Zhichen, who was in charge of chassis design, couldn't help but feel a little embarrassed when he heard Qian Dayong's words.

No matter how rich the experience is, it is impossible for their team to produce a heavy tank chassis in half a year.

"Okay. Seven pairs of road wheels or something. Let's wait until the next step. We are still considering how to reduce costs. As everyone said before, various reductions seem to be very reasonable, but everyone Think about it carefully. If we really do this reduction, what performance will our tank have in the end?" Liu Yijiu brought the matter back to the subject.

Modification design, it must be able to obtain the military approval of the current design plan.

After all, the modification is to make the tank perform better.

The work in the next step is considered to be arranged. The problem is that the difficulties encountered at present have not been solved at all.

"I personally feel that if we still do it according to the current situation, and we reduce the configuration ourselves, it is obviously inappropriate. The design requirement at the beginning is higher performance, which is what we are pursuing. Reduce performance by ourselves. The enthusiasm for the whole research will be very severe." Wang Shunyi put forward his own suggestions.

Just now, everyone proposed to reduce the configuration, not their own responsibility.

It cannot be said that everyone is selfish, but everyone thinks that the technology they are responsible for has a very large impact on the overall performance.

When the others heard this, they couldn't help but stare at each other.Their behavior is somewhat inferior.

The crux of the problem, this has to be decided by Liu Yijiu.

Liu Yijiu is the main person in charge of this project, and his will determines the various situations of the project.

After scanning for a week, Liu Yijiu shook his head, "According to the current situation, it seems that our configuration can’t be reduced. Other than that, let’s just talk about the internal ergonomics. These things are all Research by the relevant technical team in our institute has proved very important things. The state of the fighters inside the tank has a great influence on the performance of combat performance. In summer, if it is too hot, people will have no energy; in winter, it is too much. It's cold, your hands and feet are stiff, and even if your thinking speed is fast enough, you can't keep up with your movements. Under such circumstances, how do soldiers fight?"

Ergonomics, this is a key research project in the Ninth Academy.

All the research conducted by the Ninth Academy is aimed at maximizing the combat effectiveness of the military. The training of various arms is specially formulated by specialized personnel based on the human body data researched by the genetic research team.

This is a very new topic for the entire world at present.

"In terms of technology, such as intelligent aiming assistance systems, automated fire control systems, and even data connections with helicopters that act as the eyes of armored forces, on the surface, they don't seem to have much effect. In fact?" Liu Yijiu said this, and paused.
