After all, the original plan to extend the two-hour course was not unconsciously extended several times, Rao is that no matter how strong his energy is, he can't help but be a little tired, but even so, Lu Jiadong's mood is still very good, anyway, the whole new tank development team is still very enthusiastic about learning, and what is even more commendable is that as technical experts in the field, they do not blindly listen to their own explanations, and sometimes they will put forward a series of targeted questions according to the actual situation of their own experience。

In this regard, Lu Jiadong is still very encouraged, although he as a military expert who has traveled through later generations, he has advanced technical knowledge, but Lu Jiadong does not think that he can be superior to others with this knowledge, in any case, there is no so-called Yiyan Hall in the field of technology, even if it is an authority, it is just an accumulation of wealth, and if you want technological progress and continuous development, you still need to discuss and study more.

Therefore, when Lu Jiadong explained the tank technology, he would also mobilize the atmosphere of the research and development team members and encourage them to express their problems and ideas, which is also an important reason for the delay of time, but in this way, Lu Jiadong found that there are many people who have independent ideas in technology and are actively enterprising.

For example, Zhao Chenggang from the South Yunnan Special Vehicle Factory in front of him now, he didn't know much about him before, but he learned through the archives that he was born from the Workers' and Peasants' and Soldiers' University, and was the technical leader of the South Yunnan Factory。

Because of this. But after Lu Jiadong came back from the hot water, when he saw Zhao Chenggang and Liu Xueyong next to him discussing, he walked over curiously and asked softly, and Zhao Chenggang and Liu Xueyong couldn't help but be a little surprised when they saw that it was Lu Jiadong, and in the end, Liu Xueyong reacted quickly. replied to Lu Jiadong:

"We, we, we're talking about the suspension system of the tank!"

"Oh, what's new?" Lu Jiadong's face always had an indifferent smile, Zhao Chenggang was silent for a moment when he saw this, although he was a worker, peasant and soldier college student, and the time he went to college was only about two years, but in these two years, he did not herd sheep everywhere like other classmates, but put all his time on studying, even after graduating from college, he still specialized in vehicle transmission and suspension technology as always.

In particular, two years ago, he went to Japan for work to investigate, and when he saw Japan's powerful automobile industry, he could not help but have a deep sense of crisis while broadening his horizons. To this end, he collected a lot of cutting-edge vehicle technical information during the inspection, and the most attractive thing for him was the liquid gas suspension system that had just entered the practical stage, and Zhao Chenggang launched a series of research after returning to China.

When he received the design of the overall suspension system of the new tank, he wanted to apply his research results to the new tank, but Guo Zhipeng, the director of the Yunnan plant at that time, felt that his liquid gas suspension was of little value, and directly overthrew it.

Although this plan has passed the factory audit. After submitting it to the new tank leading group, it was also affirmed accordingly, but Zhao Chenggang was not happy about it. Because what he wants is to apply the liquid and gas suspension system he researched to the new tank, so that the domestic tank will be at the forefront of the world in suspension!

But the current reality makes his idea extremely slim, after all, there is not much understanding of the liquid gas suspension system in China, and there are many difficulties to overcome if you want to promote it, and these are not what he Zhao Chenggang, a small factory technician, can do, so Zhao Chenggang is no longer demanding. It's just that what he didn't expect was in today's group learning.

When Lu Jiadong, the chief designer of the new tank, talked about the tank suspension system, he actually talked about the liquid-gas suspension system, and also gave a brief introduction to the liquid-gas suspension system, although it was only a few short sentences, but it was as wonderful as gospel in Zhao Chenggang's ears:

"Now that Chief Engineer Lu understands the liquid gas suspension system. So can he, Zhao Chenggang, turn his long-cherished wish into reality?"

Zhao Chenggang's mind kept pouring out such thoughts, and unconsciously, the silent heart also beat again, because of this, Zhao Chenggang just drew the idea that had been in his heart for a long time when he was recording, and when he faced Lu Jiadong again, he couldn't hide his excitement, so he didn't know what to say for a while, and only after organizing the language a little did he speak:

"We want to apply a liquid-gas suspension device to the new tank!"

Listening to Zhao Chenggang's words, Lu Jiadong was slightly stunned, but he didn't expect Zhao Chenggang to apply the most cutting-edge suspension technology to the tank being developed, and he couldn't help but be interested:

"Is there a specific plan?"

"Yes!" Hearing Lu Jiadong's question, Zhao Chenggang was even more energetic, and after answering a sentence urgently, he hurriedly took the notebook that was close to Liu Xueyong just now, pointed to the sketch of the suggestion drawn on it, and said excitedly:

"Mr. Lu, you see, this is the sketch of the liquid-air suspension system I designed, the basic principle is to conduct the vibration of the load wheel through gas and hydraulic oil, in order to maintain the stability of the car body, at present, this suspension technology should be one of the world's advanced suspension technology, it is understood that several countries are developing tanks are preparing to apply this technology"

"It should be the Type 74 main battle tank that Japan has just put into production, and the Challenger tank being developed by the United Kingdom has applied this technology!" Zhao Chenggang was saying, Lu Jiadong nodded and interjected, Zhao Chenggang was shocked after hearing it, and then couldn't help but look at Lu Jiadong with admiration and said with admiration:

"Master Lu, I didn't expect you to even know the specific model!"

"I've seen some foreign-related materials before, and there happen to be relevant records!" Lu Jiadong replied disappreciatively, and then motioned to Zhao Chenggang to continue, and Zhao Chenggang saw that Lu Jiadong had such a deep understanding, so he did not introduce the background, but pointed to the sketch on the book and began to tell the principle, but just as Zhao Chenggang was talking about Xingtou, Lu Jiadong, who was next to him, suddenly frowned and asked a question, completely interrupting his smooth explanation:

"Cheng Gang, if you design like this, where will the gas be placed?"

"This" Zhao Chenggang pointed to the bottom of the next cylindrical shape: "Put it here, play the role of transmitting pressure!"

"What kind of gas are you going to use?"

"Then use it" Zhao Chenggang "used" for a long time and didn't say half a word, and the excitement on his face was also reduced a lot because of Lu Jiadong's question, but Zhao Chenggang did not give up, and after thinking for a while, he replied confidently:

"I haven't thought of it yet, but I'm sure we can find a suitable gas to make this vision a reality!"

"Since this is the case, then the pressure of such gas rushing into the cylinder must be very high, is ordinary steel feasible?"

"This" After hearing Lu Jiadong's question, Zhao Chenggang finally didn't know how to answer, but even if he wanted to answer, it was estimated that there was no chance, because Lu Jiadong's questions came out one after another like a series of cannons:

"If we want to use special steel, then our current smelting level has not reached such a high level of technology? And the piston inside has to be sealed in the process of movement, what kind of material can be used to resist fatigue and can be sealed? Since we want to seal, the processing accuracy must be very high, can our current machining level reach such a level? Even if these problems are all solved, the time cost and manufacturing cost required have been calculated, can we afford it?"

Faced with Lu Jiadong's series of questions, Zhao Chenggang didn't know how to answer at all, he just focused on the liquid gas suspension system itself before, and didn't think about more in-depth things at all, so after listening to Lu Jiadong's questions one after another, Zhao Chenggang was suddenly a little overwhelmed, and the excitement on his white face just now disappeared at this time.

In other words, there was a look of embarrassment, under the bright incandescent light, the blue and white flickered non-stop, and at this time, the members of the new tank development team who heard the discussion here also gathered one after another, Zhao Chenggang didn't know what to say when he saw this, so he could only blush, staring at the sketch he drew and not knowing what he was thinking, Liu Xueyong, who was sitting next to Zhao Chenggang, saw this and hurriedly played a round for this capable subordinate:

"Chief Master Lu, this is also Xiao Zhao's new research results, maybe because the time is too hasty, it is not so comprehensive"

"Even so, it's already very good to think of this!" Before Liu Xueyong finished speaking, Lu Jiadong took the words with an indifferent smile, and then patted him Zhao Chenggang's shoulder:

"You know, the liquid-gas suspension system will come in handy in the future, but the position of your gas and liquid is reversed, if the compressed gas is used as an elastic element, and the pressure is transmitted with incompressible liquid and oil, is it better to do so?"

"Treat compressed gas as an elastic element, and transmit pressure with incompressible liquid oil" Listening to Lu Jiadong's words, Zhao Chenggang first repeated a sentence, and then recited it silently several times, not only after a long time, Zhao Chenggang suddenly slapped his thigh and shouted excitedly:

"yes, I didn't think of it" (to be continued......)

PS: The weather is cold, the wind is cold, the grapefruit peel on the grapefruit body is sick, but still insist on checking the information, crazy code words, to tell the truth, for a literary monk, looking at the technical information can be described as a torment, often I want to sleep after sweeping my eyes, but for the sake of brothers and sisters, Yuzu opinion insisted, of course, there will be some small mistakes occasionally, and please brothers and sisters Haihan, of course, for the sake of Yuzu's hard work, give more monthly passes, Reward or something, Yuzu will also be more motivated, please brothers and sisters!
