Zhao Chenggang suddenly shouted in shock, startling Liu Xueyong, the chief of the technical section of the Yunnan Special Vehicle Factory who was sitting next to him, and hurriedly reminded:

"Xiao Zhao, what are you doing, didn't you see that Chief Master Lu is still here!"

Hearing Liu Xueyong's words, Zhao Chenggang couldn't help scratching his head, and responded with a smile: "Hehe, I'm a little too happy!"

Saying that, he raised his eyes and looked at Lu Jiadong opposite, his eyes were full of irrepressible admiration, and then he said excitedly: "Master Lu, you are worthy of being a genius in the military industry, you are really amazing, in fact, I am also thinking about what kind of gas can be used to be dense and do not have to be compressed, so as to complete the important function of transmitting pressure.

For this reason, I also did some experimental research, but there was no progress, I didn't expect to be so simple by Mr. Lu, you adjusted, the problem was solved, alas, why can't I get out of this brain, alas, it's so stupid, it's so stupid."

As soon as Zhao Chenggang spoke, he patted his head and sighed, but even so, he still couldn't hide the excited smile on his face, but Lu Jiadong only smiled slightly, and said softly to Zhao Chenggang:

"Actually, Cheng Gang, you can also be called a genius in terms of suspension technology!" As he spoke, Lu Jiadong picked up Zhao Chenggang's notebook, pointed to the sketch on it and continued:

"Whether in terms of structure or the combination of various components, the feasibility of this scheme is still very high, even if the confined oil and gas used as elastic elements and pressure transmission are reversed, it is also a normal phenomenon in the early stage of design, I think as long as you give Cheng Gang some time, you will find the reason for it yourself!"

In fact, Lu Jiadong is right, Zhao Chenggang's skills in suspension technology are already very good, but as he said. Staring at a place is just a bit of a bull's horn, some authorities are just confused, as long as there is enough time, or someone reminds them a little, the whole idea will inevitably be clear.

It's just that Lu Jiadong's sincere words fell in Zhao Chenggang's ears, that is, modesty and encouragement. In this regard, Zhao Chenggang didn't know what to say, he didn't expect that this Chief Master Lu would not take credit for solving such a major problem, not to help others, but to give encouragement everywhere.

This feeling is like the old professors who were put down ~ put ~ labor ~ reform on campus many years ago, and cared for him to study, which made him feel moved, but in this case, Zhao Chenggang, as a typical technical nerd, couldn't say a word of compliment. simply patted his chest and promised:

"Please rest assured, Chief Master Lu, I, Zhao Chenggang, will definitely get the liquid and gas suspension system of the new tank out!"

"This time, our new tank will not have a complicated liquid-gas suspension system"

"Why doesn't Chief Master Lu engage in a liquid-gas suspension system?" Before Lu Jiadong finished speaking, Zhao Chenggang stared at Lu Jiadong in front of him with wide eyes, and his face was full of incredulity, but Lu Jiadong nodded affirmatively:

"That's right! I think the new tank still uses a more mature torsion bar spring suspension system!"

If Lu Jiadong said before, Zhao Chenggang could still find a reason to say that he didn't hear it clearly, but he really heard what he said just now. Not only Zhao Chenggang, but also the people of the new tank development team who had already surrounded him could understand it. Everyone felt incredulous for what Lu Jiadong said just now.

The liquid gas suspension system was discussed so thoroughly, and even the core technical problems were solved, how could it still be vetoed? The people around him were incredulous, and Zhao Chenggang, who was the first to propose this plan, was even more so, and because of this, he was shocked. I couldn't help but ask positively:

"Why?"

"Because of the maturity of the technology, the complexity of the process, the cost of overruns, and of course, the shortcomings of this technology itself that cannot be restrained!" After speaking, Lu Jiadong first looked at the unbelievable Zhao Chenggang in front of him, and then glanced at the confused people around him, and got up and came to the blackboard where he had lectured before. Erasing the theoretical formula written earlier, he drew a few sketches with a chalk brush, and then pointed to the sketch of one of the cylindrical pistons, and said loudly:

This is the liquid-gas suspension system just discussed, this system is self-evident, the biggest feature is that the suspension characteristics are "nonlinear" variable rigidity, the greater the deformation of the elastic element, the greater the energy absorption, and the nonlinear increase, so that the liquid-gas suspension can keep the tank at a higher average travel speed. ”

As he spoke, Lu Jiadong took a sip of water from the teacup in front of him to moisten his throat, and then continued: "In addition, the liquid-gas suspension can also be designed as an adjustable structure, so as to realize the rise and fall of the hull, front and rear pitching and left and right tilting, improve the passing performance and survivability of the tank, and widen the high and low firing range of the tank gun, but"

Lu Jiadong paused, and then glanced at the members of the new tank development team who were sitting in the seat again, and then used the chalk in his hand to vigorously click on the sketch of the liquid-gas suspension system:

"Its shortcomings are also very obvious, first of all, the structure is complex, don't look at just a few columns and a few pistons, but this includes nearly ten kinds of parts such as power cylinders, main pistons, pressure accumulators, floating pistons, damping valves, etc.;

Again, because of the influence of factors such as processing accuracy, production technology and related materials, it will inevitably be a rapid increase in the overall cost, which will inevitably lead to a decline in the number of equipment, and a discount will be given to the improvement of the army's combat effectiveness.

But the most important problem is precisely in the impact on combat effectiveness, to put it bluntly, there is a big problem in terms of maintainability, as we all know, most of the suspension devices of the tank are installed outside the hull, and the combat link of the tank, the threats are unimaginably intricate, once the suspension system is hit by fire,

For the liquid-gas suspension system, it is tantamount to a disaster, because it is complicated and difficult to repair, not to mention that the filling of gas and liquid inside requires special devices, if it is good to say in peacetime, but what if it is in wartime? Is the harsh battlefield environment under field conditions suitable for such complex repairs?

Lu Jiadong's words were silent, even the most unacceptable Zhao Chenggang chose to be silent after puffing out his cheeks, not for anything else, just because what Lu Jiadong said was too professional, although he only said a few words, but all the technical characteristics of liquid gas suspension were put in front of everyone.

Even if the composition structure, process situation, and even the specific number of pressures are said lightly, it can be seen that Lu Jiadong's research on liquid gas suspension has reached an unimaginable height in advance, and because of this, his comments on the advantages and disadvantages of liquid gas suspension devices will be more convincing, and even Zhao Chenggang, who has in-depth research in this area, is also sighing to himself, and then slowly begins to face up to whether his persistence is really worth it!

And Lu Jiadong, who was standing on the podium, saw the members of the R&D team who were puzzled, nodding, or pondering, and raised his voice again:

In addition to the specific performance of weapons and equipment, we should also consider the battlefield adaptability of this type of equipment, the environment of the combat area, whether the operation of officers and soldiers is simple and easy to understand, whether the logistics maintenance is convenient and fast, whether the training and combat are strong and durable, and whether the cost of production and manufacturing is low.

Listening to Lu Jiadong's words, the people below all began to whisper, before Lu Jiadong talked about the technical theory of the specific equipment of the tank, at most it involves the summary of the three major capabilities of tank firepower, protection and mobility, and does not involve the overall idea of weapons and equipment research and development, because of this, when the members of the tank development team present heard these words, it can be said that they were deafening, but Lu Jiadong's words did not stop there, but continued:

"Therefore, a weapon and equipment is not all the high-tech piled up is an invincible trump card, nor is it because of the simplicity of the simpler the better, the key is to look at the combat mission of the weapon and equipment, the predetermined battlefield environment, as well as the traditional habits of using the army, etc., and as a designer, not only to take into account the specific situation, but also to stand at the height of the overall situation to examine whether the components and systems involved in them match the whole,

Whether it can achieve the expected effect with other related systems, just like the new tank we are currently developing, whether it is the suspension system, transmission system, or fire strike system, armor protection system or fire control observation and sighting system, the advanced performance of a single item does not represent the whole, only the overall performance to complete the breakthrough is the ultimate goal, so everyone here must take a long-term view, stand on the overall situation to examine what they design, only in this way, will become an excellent weapons and equipment designer!"

As soon as Lu Jiadong's voice fell, the scene was silent at first, I don't know how long it took, there was a clapping in a corner, followed by the second, third, and fourth, and in the blink of an eye, everyone present applauded, and the entire warehouse was instantly submerged in the vast applause (to be continued......
