The reduction of the 1062 tank in the text is like a self-destructing Great Wall

Next chapter

"The hydraulic system does take up a lot of the cost. And the current situation, I don't think there is any need to design six pairs of load wheels, after our many simulation analysis, found that according to our current design, the weight of the entire tank has reached 61 tons, six pairs of load wheels to bear the weight, which makes each load wheel bear the weight is relatively high. This has caused a lot of burden on the hydraulic system, especially in terms of suspension...... "As the person in charge of the hydraulic system, Shi Chuanxiang doesn't want to end up making the technology they have worked so hard for so many years useless.

The Longwei tanks all use hydraulic systems, and the Republic uses them themselves, and they don't use them if they don't export them, and some can't say it, right?

Six pairs of weight-bearing wheels, which were proposed by Liu Yijiu when he gambled with 617.

Moreover, this is a weight-bearing mode that exceeds a certain range.

The average basic weight of each load wheel of a 38-ton domestic tank and five teams of load wheels is only 38 tons, which will not be too high even if the friction during the march is calculated.

The load of 61 tons, six pairs of tanks shared, each wheel carried a base weight of more than five tons, plus the friction during the march, marching kinetic energy, etc., each wheel carried a weight of more than ten tons, not to mention, the maximum speed of the six-wheel plan reached 70 kilometers per hour, which is much higher than the Type 59 and are both.

"Indeed, we felt that perhaps it would be more appropriate to replace six pairs of large diameter wheels with more load wheels of small and medium diameters." When Jiang Ming said this, he didn't dare to stare at Liu Yijiu's eyes.

If you rotate from six pairs of weights to seven pairs of loads, it will be a very big project.

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

Liu Yijiu himself proposed to design and manufacture six pairs of load-bearing wheels of the tank, although at the beginning they were also very enthusiastic about this project, when the sample was produced, they found the problem, after simulation, only to find that the tonnage is too large, and the gravity of the large-diameter load-bearing wheel is even larger, which is a big test for the suspension system and the transmission system.

Even when it comes to maintenance later, the consumption of the soldier's body is relatively large.

"Is there a test number?" Liu Yijiu frowned.

He didn't say that he had to have six pairs of weight wheels, as long as it was appropriate, it didn't matter how many pairs of load wheels he used.

With the improvement of the level of science and technology, the performance of the tank will no longer rely on thicker armor and stronger offensive power to distinguish heavy or medium light. If all the armor is replaced with graphene combined with carbon fiber, and the tank gun part is replaced with a lighter material, the weight of the entire tank will be reduced to less than 35 tons.

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

It's just that that kind of cost is unbearable for any country.

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

"Yes, all with me. I was just about to report to you and propose a revision plan...... Jiang Ming heard Liu Yijiu's words, and immediately took out a copy of the article from the table in front of him, which was only five or six pages, but the number on these five or six pages was obtained by spending hundreds of millions of dollars.

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

The number jù above the text is not just the number jù of a certain scheme, but compared with the number jù in the case of six pairs of load wheels, the difference between the various numbers jù is clear at a glance for the impact on the tank.

The results at the end of the text fully proved that in the case of 7 teams of medium-diameter load wheels bearing 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 needs to be much lower.

The entire design team thinks that the current design is still adopted, just to modify the chassis design, change the load wheels, and make corresponding technical adjustments to the suspension system and shock absorption system.

It's also very clear.

"Why don't we lower this configuration a little bit, and the performance of the Dragon Guard is about the same, and redesign a heavy tank?" Jiang Ming saw that Liu Yijiu had been staring at Wen Jiàn silently all the time, and he didn't speak, and the whole person seemed very strict, which caused a lot of pressure on them.

Everyone else also stared at Liu Yijiu nervously.

Liu Yijiu is authoritative in this regard, and the overall design is Liu Yijiu's design ideas, and many of the technologies are staring at him.

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

"Is that what everybody means?" Liu Yijiu glanced around and saw that they were all staring at him, as if waiting for his reply.

Everyone nodded violently.

When it comes to design, you have to choose the best design solution.

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

"At present, if you modify the design, redesign the site or something, it will be too late. Anyway, in the current situation, because the cost of our design scheme is too high, even if the military has too much equipment, it will not have too many of them. After the six rounds of planning and finalization, the focus of our entire team can be put into the retrofit design. Liu Yijiu did not emphasize the need to use six pairs of weight wheels.

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

In this era when tanks were heavier and more advanced, the Republic needed to use heavy tanks with six pairs of load-bearing wheels, mainly to deal with the threat of the huge armored clusters of the Soviet Union in the north.

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

"In half a year, can we design a full-fledged tank chassis?" 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, but only the chassis, how long did it take us to design?" Even now, there are still some minor glitches; ”

The chassis is the key to the entire tank.

This is what the Ninth Academy lacks.

The Ninth Academy has been designing the chassis since the late seventies, and now almost ten years have passed, and only one barely usable chassis has been produced.

"It turns out that we don't have the technical accumulation in this area, after so many years of design, experience accumulation, we also have a relatively rich design experience, Lao Zhao, redesign the chassis, there is no big problem, right?" Qian Dayong wished that their chariot division would have more designs to come out.

What he said is indeed right, in the past few decades, the Ninth Academy has invested a lot in this area regardless of the 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 really impossible for their team to come up with a heavy tank chassis in half a year.

"Alright, seven pairs of weight wheels or something, let's wait until the next step to get it. At present, everyone is still considering how to reduce costs. As we said earlier, all kinds of reductions seem to be very reasonable, but if you think about it carefully, if you really reduce it like this, what performance will our tank have in the end? Liu Yijiu brought things back to the topic.

The modified design must be able to obtain the approval of the military as the current design scheme.

After all, the modification was made to make the performance of the tank better.

The next step of the work can be regarded as being arranged, but the difficulties encountered at present have not been solved at all.

"Personally, I think that it would be inappropriate for us to do what we do according to the current situation and reduce the allocation ourselves. From the beginning, the design required higher performance, and that's what we're after. Reducing performance by yourself will be a very big blow to the enthusiasm of the whole research. Wang Shunyi put forward his own proposal.

At the time just now, everyone proposed to reduce the configuration was not their own responsibility.

It's not that everyone is selfish, but 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 but look at each other. Their behavior is somewhat inferior.

The crux of the matter has to be decided by Liu Yijiu.

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

After glancing for a week, Liu Yijiu shook his head, "According to the current situation, it seems that our configurations really can't be reduced." Not to mention anything else, let's just talk about the internal ergonomics, which have been confirmed by the relevant technical team in our hospital and confirmed to be very important. The state of the fighters inside the tank has a great impact on the performance of the operation. In summer, if it is too hot, people have no spirit; In winter, it is too cold, the hands and feet are stiff, and even if the thinking speed is fast enough, the movements cannot keep up, how can the soldiers fight in such a situation? ”

Ergonomics is a key research project in the Ninth Academy.

All the research of the Ninth Academy is aimed at maximizing the combat effectiveness of the army, and the training of each branch of the military is specially formulated by special people according to the number of human bodies studied by the genetic research team.

This is a very new topic for the whole world at the moment.

"In terms of technology, such as intelligent aiming assistance systems, automated fire control systems, and even the number of helicopters that are the eyes of armored troops, etc., it seems that it does not have much effect on the surface, but in fact, it is?" Liu Yijiu said here and paused
