Zhengxin R&D Center.
Since the establishment of Zhengxin, this is the first time for the engineers in the R&D center to experience the normal R&D process... Working from nine to five every day, this is something they have never experienced since they joined Zhengxin. !
But the facts once again proved that Li Fanyu would not let them go,
Because he signed a confidentiality agreement with Lu Mingde, Li Fanyu found Lao Zhang first about this matter.
When Professor Zhang heard the news that Zhengxin was taking orders from the military to develop engines for fourth-generation tanks, he was even happier than he was when he celebrated his 60th birthday last month.
He waved his hand directly, expressing his 100% support.
"Xiao Fan, this is a good thing. Zhengxin's participation in such an order means that we can make greater contributions to the country. You must not neglect this matter, I I fully support you.”
Li Fan smiled bitterly and nodded.
"As for you signing a confidentiality agreement, then this matter cannot be made public. My opinion is that you take the lead and ask the team to cooperate with you. What do you think?"
"Well, I think so too. But Fu Fang and the others are working on the research and development of the Range Rover. Who should be used and whom should not be used?"
Professor Zhang thought for a moment and said: "Fu Fang is the chief engineer now and needs to coordinate the affairs of the R&D center. Liu Qing is capable, but his temper is too unrestrained and is not suitable for such a confidential task. I think Wang Yu is the calm one. A little, what do you think?”
Li Fanyu nodded, "Okay, then I'll call them over."
……
Although Wang Yu has been secretly confirmed with Lao Zhang, the matter of allocating manpower to form a critical team cannot be hidden from the other two. So Li Fanyu simply called over the three top students and briefly talked about forming a team to develop the fourth-generation engine.
Ignoring Liu Qing's decision, Li Fanyu directly announced the decision to transfer Wang Yu's team.
"Brother Fan! You should come to me for such a gratifying matter!"
Li Fanyu looked at Liu Qing, who was anxious and sweating from the tip of his nose, and spread his hands: "This is a military cooperation project, and it needs to strictly abide by confidentiality regulations. Are you sure you can keep your mouth shut? Not disclosed? ”
"What's wrong with that! I keep my mouth shut!"
Wang Yu, who was folding his arms and secretly feeling proud, saw that his friend was trying to steal his job. He immediately shot a cold arrow and said, "Oh? Really? Who was involved in the matter that Brother Fan had with Zhou Qingyu in the United States?" Released in the center’s communication group?”
"Huh?" Li Fanyu looked at Liu Qing coldly and winced.
Paralysis! I asked why Sister An has been paying attention to Zhou Qingyu recently. It turns out that the root cause is here!
Professor Zhang really saw you right, you don’t have a clue! How can something that affects unity be promoted everywhere?
Huh? !
Thinking of this, he waved his hand and said, "Come on, it's settled! The development of the fourth-generation engine is absolutely confidential. Let me remind you again. Don't let the news leak to the outside world. Even if it is within the group, there is no need to say it. I definitely can’t say it, do you know? I signed a confidentiality agreement with the military. If the secret comes from our official source, we will have a drink!”
This is not directed at Liu Qing, but serious words. Of course the three of them know the importance of this.
Xu Fufang had amusement on his face, Liu Qing had annoyance on his face, and Wang Yu had a sinister gloating on his face. But despite their different expressions, they all responded loudly, "Copy that."
Although the military has not communicated the performance requirements of the fourth-generation engine, the troops have not yet used food and grass. After setting the goal, the R&D center underwent a large-scale transfer.
While we were actively preparing here, the military finally took action.
On the fourth day after meeting with Lu Mingde, the military sent someone over. At the same time as the request for the fourth-generation tank engine was delivered, Zhengxin also sent a large number of "bodyguards".
Li Fanyu still underestimated this confidentiality agreement.
This is the first time that the military has cooperated with a private enterprise on the core original components of important weapons. Although Zhengxin has shown its R&D strength and loyalty to the country and sense of responsibility in the past, it seems that the higher-ups still engage in confidential work with private enterprises. I don't feel comfortable working.
In order to ensure strict confidentiality in the development process of the fourth-generation tank engine, the Science and Technology Department of the General Staff, also known as the legendary Seventh Department, specially sent people over to supervise and protect Zhengxin.
Although only ten people came, Li Fanyu had no doubts about what these ten people with no expressions would do if someone deliberately leaked the secret during the research and development process of Zhengxin or was infiltrated by someone with intentions.
It was in this environment that the Zhengxin R&D Center’s fourth-generation tank engine project, code-named SXJXW, was launched.
Why come up with such a difficult-to-pronounce code name?
The first is to prevent the project from leaking its name, and the second is to give the project a certain deep meaning.
SXJXW, quick-acting Jiuxin Pill...
That's right, the goal of the project has been quite clear since its name - to cure the heart disease of the fourth-generation tank!
Because the fourth generation tank is strictly speaking, the only thing missing is the engine that has not been finalized, and other parts have been roughly completed.
So the difficult question that the general assembly gave Zhengxin was not an analysis question, but a proposition composition.
Based on the existing information parameters of the fourth-generation tanks, there are quite complicated requirements for the engine; from basic performance to battlefield adaptability, from displacement to endurance, from the approximate size of the engine to accessories, Li It seems to me that it is quite complicated.
It can be said that this kind of research and development is almost like making an eight-part essay.
Looking at too many rules and regulations will make people lose the confidence to give it a try. And Zhengxin fundamentally has no basis for the research and development of large-displacement diesel engines.
So Li Fanyu discussed with Wang Yu and decided to put aside those rules and constraints first. Gather your strength and conquer one point first!
The first step is to make a diesel engine that can pass the performance test!
As for the impact resistance and tactical adaptability, let’s leave it aside for now. Start with basic performance such as power, torque, and displacement, and draw a shelf.
The reason why the engine of a tank is different from the diesel engine of a conventional car is mainly due to the characteristics of the tank.
The development direction of tanks since their emergence is to hit farther, have stronger protection, and run faster. Ignoring the third point for now, let’s talk about the first two points. To shoot farther, more advanced artillery and fire control systems are required. Stronger protection requires the use of higher-strength armor.
Both of these points are making the tank heavier and heavier.
Nowadays, mainstream main battle tanks basically weigh more than 60 tons. Being able to drive this weight and move freely in the battlefield environment limits, or in other words, establishes the main tone of its engine.
That is, power, revolutions, and torque!
Needless to say power, the test depends on how fast the tank can run and how heavy it can pull. Torque represents the tank's flexibility in combat and the most important off-road capability.
So in response to these two points, Li Fanyu and Wang Yu worked with the team to put on a show.
Although it has no experience in the research and development of tank engines, Zhengshin has just completed two diesel engines for off-road vehicles. So this shelf was quickly erected by everyone's joint efforts.
What is the conventional way to pursue power and torque?
Increase the number of cylinders, increase the cylinder diameter, and increase the piston stroke!
This may not be straightforward.
To put it simply, there are more, thicker and longer cylinders in the assembly!
So in a way, the engine wants to have power. It's the same as trying to revive an impotent man!
