"The torsion bar spring suspension system is a very old suspension technology, so should our new tanks really use the outdated technology before the Second World War?" When the applause gradually slowed down, but it had not completely stopped, a loud question suddenly appeared in the corner of the third row, and the gradually silent applause also stopped instantly because of this question, and at the same time, everyone's eyes were focused on the corner of the third row, as if countless shining white lights moved the center of the podium to that inconspicuous corner in an instant, and Zhao Chenggang, who was standing upright, naturally became the focus of the center.

It's just that Liu Xueyong, the chief of the technical section of the Yunnan Special Vehicle Factory, who is also in the center, faced the eyes that seemed to be searchlights, and suddenly felt a little panicked in his heart, so he gently pulled Zhao Chenggang, who had already stood up, and motioned him to sit down quickly, but Zhao Chenggang turned a blind eye to this, and still stood there stubbornly, the expression on his face was even more firm and abnormal, like a defender with a rock-like heart, guarding the beliefs and ideals in his heart.

In fact, it is true, originally he saw that Lu Jiadong knew so much about the liquid gas suspension system, and the hope hidden in his heart couldn't help but burn again, thinking that he could finally turn his dream into reality, and then Lu Jiadong's understanding and mastery of liquid gas suspension technology made Zhao Chenggang feel that it was no longer a question of whether it could be realized, but basically a sure thing.

It's just that what he didn't expect was that Lu Jiadong once again vetoed the proposal to apply the liquid-gas suspension system to the new tank, although with Lu Jiadong's unparalleled technical knowledge and strategic vision, Zhao Chenggang also felt that it was very reasonable, but no matter what, the dream in his heart could not be extinguished because of this,

What's more, as a technical talent with outstanding ability in transmission and suspension technology, he is very aware of the technical characteristics of the torsion bar spring suspension system proposed by Lu Jiadong, and he is also well aware of the pros and cons. So after thinking about it for a long time, Zhao Chenggang still resolutely stood up and worked hard for his dream again:

"Torsion bar spring suspension technology is an old technology that began to be applied in the twenties of this century, and it was widely used in World War II, but the effect is not ideal, for example, the suspension system of the 'Tiger' tank developed by Germany after World War II is used in this technology.

Judging from the actual combat situation, this technology has the disadvantages of broken steel shaft, inconvenient maintenance, and complex production, and this is also one of the important factors affecting the production and power of the German 'Tiger' tank, so I think it is not appropriate for Mr. Lu to abandon the liquid-gas suspension system with better effect on the new tank, and switch to a more conservative torsion bar suspension system!"

As soon as Zhao Chenggang finished speaking, the members of the tank development team in the seat instantly broke out into a noisy discussion, and no one thought that Zhao Chenggang would question Lu Jiadong, who was the chief designer of the new tank. And it may be a very obvious mistake, from the source of the technology and related to the establishment of the right, so how should Lu Jiadong deal with it?

You must know that Lu Jiadong is currently a well-known military genius in China, with Type 78 assault rifles, Type 80 light automatic grenade launchers, and 52 times caliber 155mm howitzers that have just been installed in the army and a new type of artillery reconnaissance and school firing radar, each of which is a well-known star product in the military industry, even if Lu Jiadong has no experience in developing tank armored vehicles before.

However, the level of proficiency that Lu Jiadong has shown in all aspects of tank technology these days is as meticulous and well-organized as the explanation of the suspension system and the design of weapons and equipment. Almost no one doubted Lu Jiadong's technical ability in the field of tanks, and thus established absolute authority in the new tank development team.

Unexpectedly, today someone would openly stand up and challenge the greatest authority of the new tank development team. How can this not surprise everyone present, and in an instant, there are those who are surprised, worried, watchful, and snickering in the entire warehouse.

However, no matter what they thought in their hearts, everyone's eyes were invariably focused on Lu Jiadong in the center of the podium, and they wanted to see how Lu Jiadong should deal with such a situation, whether it was an angry reprimand, or a relative reassurance after hearing the words so that they could settle accounts together afterwards?

But one way or another. Everyone present felt that Lu Jiadong would inevitably be angry, even if Lu Jiadong was broad-minded, as a well-known and high-ranking chief designer, it was an extremely disgraceful thing to be pointed out in public by an unknown technician.

Since this is the case, Zhao Chenggang's fate must be doomed. You must know that Lu Jiadong is not only the chief designer of the new tank, but also the executive deputy leader of the research and development leading group, and has a good relationship with several leaders of the headquarters.

In fact, Zhao Chenggang at this time also faintly regretted it, thinking about whether the opposition in public would cause Lu Jiadong's anger, thinking about whether it would be better if he was dealing with it a little smoother, so that Lu Jiadong would not be able to get off the stage, but now the words are like spilled water, and it is difficult to take it back, since it is no longer necessary to look forward and backward, he can only go one way to the black, is it thunder or a dark arrow, he Zhao Chenggang accepted it calmly, and figured this out, Zhao Chenggang's waist straightened up, and his face also put on a righteous and awe-inspiring appearance, ready to fight all the preparations。

However, to everyone's surprise, Lu Jiadong neither pointed at Zhao Chenggang's nose and scolded him angrily as the angry young people imagined, nor did he let Zhao Chenggang sit down first as the conspiracy theorists estimated, and then Wang Gu talked about him left and right, and then settled the accounts together, but nodded at Zhao Chenggang with that indifferent smile as usual:

"Cheng Gang is right, torsion bar spring is indeed an old technology!"

As soon as Lu Jiadong's words came out, the entire warehouse was in an uproar, what did the young chief designer mean by saying this, could it be that he admitted his mistake and failed, otherwise why would he affirm Zhao Chenggang's point of view? Could it be that the new tank suspension system is going to be turned around again and ready to apply the liquid gas suspension system? Countless questions flashed through everyone's minds in an instant, and they didn't have time to think about the answers, but at this moment, Lu Jiadong's words brought them back to reality from endless doubts:

"The principle of the torsion bar spring suspension system is actually to use a long metal rod, installed at the bottom of the body, the length is about the same as the width of the body, and then use the bracket and the balance shaft to connect with the load wheel, and twist the torsion bar with the up and down jumping of the load wheel during the tank driving to absorb the impact energy of the ground on the car body!"

Lu Jiadong said while explaining on another simple hanging device diagram on the blackboard, summarizing the technical characteristics of the torsion bar suspension system in a few words, but his words did not stop there:

"In the Second World War, this technology was widely used, and Germany used it the most, especially in the No. 3 tank they developed, which achieved very good results, not only the production process, maintenance, less space in the car, but also light weight and long service life.

It is precisely because of the good results of this suspension technology that German designers have widely used this technology in subsequent tank development, but they have ignored two most critical factors!"

Speaking of this, Lu Jiadong paused, and the members of the new tank development team sitting below also held their breath at this time, looking forward to Lu Jiadong's next speech, and Lu Jiadong did not let the people present wait for a long time, took a sip of the tea in the cup and moistened his throat and continued to say aloud:

"First, in order to seek new changes, they made the original mature and simple technology more and more complicated; second, they overestimated the material level and process manufacturing capacity at that time, and the designed torsion bar could not withstand the huge impact force of heavy tanks like the 'Tiger' tank, resulting in the torsion bar spring often breaking at the same time, it was also very tricky in terms of maintenance support!"

"In this way, the key to this technology is in terms of torsion bar materials and processes!"

"The Type 59 and Type 69 tanks we studied as an example in the afternoon are also torsion bar spring suspension systems, which shows that although this suspension is old, it is still very mature!"

"How much does the Type 59 and Type 69 weigh in battle? Our new main battle tank is more than 40 tons, and this kind of impact force can the original Type 59 torsion bar spring withstand?"

"This doesn't work, that doesn't work, do you want to apply the independent coil spring suspension on the British 'Chieftain' tank?"

"That suspension technology is older"

As soon as Lu Jiadong's voice fell, the discussion of the tank development team members present sounded again, no matter what, the people who can sit here are not ordinary people, Lu Jiadong's words They can naturally hear the doorway, that is, although Zhao Chenggang's questioning sounds right, but it is very biased, and several of the premises are not pointed out.

However, Lu Jiadong used his deep knowledge reserve and rigorous examples and data to analyze the technology more thoroughly, so that in comparison, the two can make a judgment on which is better or worse, and because of this, everyone present no longer paid attention to Zhao Chenggang's doubts about whether it could be successful, but focused on what kind of suspension system to use.

After all, Zhao Chenggang's questioning is just a small episode in the general direction of tank development, and he can shake Lu Jiadong's status, so naturally there are people who are not afraid of big things to watch, but once there is no hope, everyone will immediately forget him in the next second, and how can Zhao Chenggang at this time not feel the changes of everyone, but he is helpless, he can only stand there motionless and stunned (to be continued......
