"The hydraulic system does occupy a lot of costs. And in our current situation, I don't think it is necessary to design six-pair load wheels. After many simulations and analysis, we found that according to our current design, the weight of the entire tank reaches 61 tons, and the six-pair load wheels bear these weights, which makes each load wheel bear relatively high weight. This puts a great burden on the hydraulic system, especially in terms of suspension..." As the person in charge of the hydraulic system, Shi Chuanxiang does not want to end up making the technology that they have worked hard for so many years without using it.

The Longwei tanks all use hydraulic systems, and the Republic uses them themselves. If you don’t know how to export them, it’s a bit unreasonable, right?

The six pairs of heavy load wheels were proposed by Liu Yijiu when he was betting with 617.

Moreover, this is the weight-bearing mode adopted when the weight exceeds a certain range.

The 38-ton domestic tanks and the five teams of the load-bearing wheels bear the average base weight of each load-bearing wheel is only 38 tons. Even if the friction during the travel process is calculated, it will not be too high.

With a load of 61 tons and six pairs of tanks, each wheel bears a foundation weight of more than five tons. With the friction force, kinetic energy during the travel process, the weight of each wheel bears more than ten tons. What's more, the planned maximum speed of the six wheels reaches 70 kilometers per hour, which is much higher than that of Type 59.

"Indeed, we think that perhaps it is more suitable to use more load-bearing wheels with small and medium diameters to replace six pairs of large diameters." Jiang Ming did not dare to stare at Liu Yijiu in the eyes when he said this.

If you change from six pairs of load bearings to seven pairs of load bearings, this will be a very big project.

The territory needs to be redesigned, and even the layout of the entire tank must be modified.

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

Even when it is maintained later, the physical energy consumption of soldiers is relatively large.

"Is there any test data?" Liu Yijiu frowned.

He never said that there must be six pairs of load-bearing wheels. As long as it is appropriate, it is not a problem to use the number of load-bearing wheels;

With the improvement of technology, the performance of the tank will no longer be based on thicker armor and stronger offensive power to distinguish between heavy or medium-light. If all the armor is replaced with graphene and carbon fiber, and the tank gun part is replaced with lighter mass 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, all inside the tanks carry various precisely guided missiles...

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

We can only wait until the technology develops in the future and the cost of various materials will be reduced before we adopt these methods.

"Yes, I'm taking them all. I'm just about to report to you and propose a modification plan..." Jiang Ming immediately took out a document from the table in front of him, with only five or six pages of paper, but the data on these five or six pages of paper cost hundreds of millions of dollars.

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

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

The result at the end of the document fully proves that when the medium-diameter load-bearing wheel of the 7 team bears the weight of 61 tons of the entire tank, the speed of the tank can be faster, and the performance required by the hydraulic suspension system is much lower.

The modified design scheme attached to the latter does not have complete drawings, but is just a list of some configurations. The entire design team thinks that it is still used to use the current various designs, just modify the chassis design, change the load-bearing wheels, and make corresponding technical adjustments to the suspension system and shock absorption system.

I also understand very clearly.

"Or, let's reduce this configuration to achieve the same performance as Long Guard. Redesign a heavy tank?" Jiang Ming saw Liu Yijiu staring at the file silently and not talking, and he seemed very serious, which put a lot of pressure on them.

The others were also staring at Liu Yijiu nervously.

Liu Yijiu is considered an authoritative in this regard. The overall design was proposed by Liu Yijiu, and many of the techniques he focused on.

He has a great influence on the entire tank design plan.

"Does everyone mean this?" Liu Yijiu glanced around and stared at him when he saw him, as if waiting for his reply.

Everyone nodded violently.

As for design, you must choose the best design plan.

The six pairs of load bearing wheels are not suitable, and the strength requirements for load bearing wheels are very high. It has been proven that there are better options, so there is naturally no need to waste too much time on this, right?

"At present, if we modify the design, redesign the territory, etc., it will be too late. Anyway, under the current circumstances, our design plan is too expensive, and even if the military has too much equipment, it will not have too many. After the six-round plan design is finalized, our entire team's work focus can be devoted to the modification design." Liu Yijiu did not emphasize that the six-pair load wheels must be used.

For him, as long as the effect can be achieved, even if two pairs of load bearing wheels are used, there will be no problem.

In this era when the more heavy the tank is and the more advanced the performance, the Republic needed to use six pairs of heavy tanks with heavy wheels to deal with the threat of the huge armored cluster of the Northern Soviet Union.

"Don't we have half a year?" He did it just by saying that, this is the style of the Ninth Academy.

"Can we design a mature tank chassis in half a year?" Liu Yijiu smiled bitterly and asked Qian Dayong, "Most of the technologies used in this tank are upgraded from the related technologies and related technologies of the Longwei tank. Only the chassis, how long did it take for us to design it? Even now, there are still some minor problems reads;!"

The chassis is the key to the entire tank.

This is what the Ninth Institute lacks.

The Ninth Yuan started designing the chassis in the late 1970s, and it has been almost ten years since then, and only one barely available chassis.

"It turns out that we do not have the technical accumulation in this area. After so many years of design and experience, we have also gained rich design experience. Lao Zhao, there is no big problem with redesigning the chassis, right?" Qian Dayong hoped that their chariot partition would have more designs.

What he said is indeed correct. In the past few decades, the Ninth Hospital has invested a lot of experience in this area regardless of cost.

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

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

"Okay, seven pairs of heavy load wheels, wait until the next step of work. At present, everyone is still considering how to reduce costs. As we have said before, all kinds of reductions seem to make sense, but think about it carefully. If we really reduce this, what performance will our tank have in the end?" Liu Yijiu brought the matter back to the topic.

For modification design, it must be able to obtain the current design plan recognized by the military.

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

The next step of work has been arranged, and the problem is that the difficulties encountered at present have not been solved at all.

"I personally think that it would be obviously inappropriate if we do it according to the current situation and reduce the matching ourselves. The design requirement at the beginning was higher performance, which is what we pursue. Reducing performance by ourselves will have a great impact on the enthusiasm of the entire research." Wang Shunyi put forward his own suggestions.

Just now, the reduction configurations proposed by everyone were not responsible for themselves.

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

When the others heard this, they couldn't help looking at each other. Their behavior was a bit inferior.

The key to the problem is decided by Liu Yijiu.

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

After a week of scanning, Liu Yijiu shook his head, "According to the current situation, our configurations really cannot be reduced. Not to mention anything else, let's just talk about internal ergonomic engineering. These things have been confirmed by the relevant technical teams in our institute. The state of the warriors inside the tank has a great impact on the performance of combat performance. In summer, if it is too hot, people will have no energy; in winter, they are too cold, their hands and feet are stiff, and even if their thinking speed is fast enough, their movements cannot keep up, how can soldiers fight in this situation?"

Ergonomic engineering is a key research project in the Ninth Academy.

All the research in the Ninth Academy is to maximize the combat effectiveness of the army. The training of various types of troops is specially formulated based on human data studied by the gene 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 helicopter data connections that are used as armored forces, they don't seem to have much effect on the surface, but in fact?" Liu Yijiu said here, pausing.
