Zhengxin R&D Center. Pen & Fun & Pavilion www.biquge.info

Since the establishment of Da Zhengxin, the engineers of the R&D center have experienced the normal R&D process for the first time...... Getting off work from 9 to 5 every day, this is something I haven't experienced since I entered the main letter!

But facts have once again proved that Li Fanyu will not let them go.

Because he signed a confidentiality agreement with Lu Mingde, Li Fanyu found Lao Zhang first in this matter.

When Professor Zhang heard the news that Zhengxin was going to undertake an order from the military to develop an engine for the fourth-generation tank, he was even happier than he was to celebrate his 60th birthday last month.

directly waved his hand and expressed his 10% support.

"Xiao Fan, this matter is a good thing. Zhengxin can participate in such an order, which means that we can already make greater contributions to the country. You must not slack off on this matter, I fully support you. ”

Li Fanyu smiled bitterly and nodded.

"As for the non-disclosure agreement you signed, then the matter cannot be made known. My opinion is that you take the lead and ask the team to cooperate with you. What do you think?"

"Well, that's what I thought too. But they are working on the development of Range Rover, who is not using whom?"

Professor Zhang thought for a moment and said, "Compound is now the chief engineer, and it needs to coordinate the affairs of the R&D center. Liu Qing's ability is okay, but his temperament is too out-of-the-box to be suitable for such a secret task. I think it's just Wang Yu, be calm, what do you say?"

Li Fanyu nodded, "Cheng, then I'll go and call them over." ”

……

Although Wang Yu has been agreed with Lao Zhang, it is impossible to hide the matter of transferring people to form a team to attack the other two. Therefore, Li Fanyu simply called all the three scholars over and roughly talked about the formation of a team to start the research and development of the fourth-generation engine.

Regardless of Liu Qing's jumping feet, Li Fanyu directly announced the decision to transfer Wang Yu's team.

"I'll wipe Brother Fan! Find me for such a competitive thing, find me, find me!"

Li Fanyu looked at Liu Qing, who was sweating on the tip of his nose, and spread his hands: "This is a military cooperation project, and it needs to be carried out in strict compliance with confidentiality regulations." Are you sure you can keep your mouth shut and not reveal the slightest bit of information?"

"What's wrong with that! I'm keeping my mouth shut!"

Wang Yu, who was secretly proud of holding his arms on the side, saw that his friend was going to rob him of his work, and immediately let go of the cold arrow and said: "Oh, yes? Who let Brother Fan talk to Zhou in the United States in the exchange group of the center?"

"Huh?" Li Fanyu looked at Liu Qing coldly, and shrunk the latter's neck.

I said why Sister An has been paying attention to Zhou Qingyu lately, and the root cause is here!

Professor Zhang really didn't misunderstand you, there is no one who talks about it! How can such a thing that affects unity be publicized everywhere?

Yes?!

Thinking of this, he waved his hand, "Come on, it's decided! The matter of the development of the fourth-generation engine is absolutely confidential, and I will remind you again." Don't leak the news to the outside world, even if it's within the group, you can't say it if you don't need to say it, you know? I signed a confidentiality agreement with the military, if it leaks from our Zhengxin, then we will have a pot to drink!"

This is not aimed at Liu Qing, but serious words, of course the three of them know the importance of this.

Xu Fufang's face was amused, Liu Qing's face was annoyed, and Wang Yu's face was gloating with a dark belly. But despite the difference in expression, they all responded loudly "Received".

Although the military has not yet conveyed the performance requirements of the fourth-generation engine, the soldiers and horses have not moved the grain and grass first. After the goal was determined, the R&D center ushered in a large-scale transfer.

After the efforts of active preparations, the military has finally moved.

On the fourth day of meeting Lu Mingde, the military sent people over. At the same time as the request for the fourth-generation tank engine was delivered, a large number of "bodyguards" were also sent to Zhengxin.

Li Fanyu still underestimated this confidentiality agreement.

This is the first time that the military has cooperated with a private enterprise on the core components of important weapons, and although Zhengxin has shown its own R&D strength and a sense of loyalty to the country in the past, it is still not very comfortable for private enterprises to engage in secret-related work.

In order to ensure strict secrecy during the development of the fourth-generation tank engine, the Science and Technology Department of the General Staff Department, also known as the legendary Seventh Division, specially sent people over to supervise and protect Zhengxin.

Although there were only ten people here, Li Fanyu had no doubt that if someone in Zhengxin deliberately leaked secrets or was infiltrated by someone with a heart during the research and development process, what kind of thing would these ten people who didn't even have expressions do.

It was in this environment that the fourth-generation tank engine project codenamed SXJXW of Zhengxin R&D Center was launched.

Why such an awkward codename?

The first is to keep the project from leaking secrets from the name, and the second is to give the project a certain deep meaning.

SXJXW, a fast-acting heart-saving pill......

That's right, from the very beginning of the naming of the project, the goal was quite clear - to cure the heart disease of the fourth-generation tank!

Because the fourth-generation tank is strictly speaking, this engine has not been decided, and the other parts have been roughly completed.

Therefore, the difficult problem that the final assembly to Zhengxin is not an analytical question, but a propositional composition.

According to the existing information parameters of the fourth-generation tank, quite complicated requirements have been drawn for the engine; from basic performance to battlefield adaptability, from displacement to endurance, from the approximate size of the engine to the accessories, in Li Fanyu's view, it is really quite complicated.

It can be said that this kind of research and development is almost the same as doing eight strands.

Looking at too many rules and regulations will make people lose the confidence to give it a go. Zhengxin's research and development of large-displacement diesel engines is fundamentally unfounded.

So Li Fanyu discussed it with Wang Yu and decided to leave those regulations and constraints behind first. Gather your strength to conquer a little first!

First of all, the first step is to make a diesel engine that can pass the performance test!

As for what blow resistance and tactical adaptability will be left out first, starting with basic performance such as power, torque, displacement, etc., and pulling out a shelf.

The reason why it is said that the engine of the tank is different from the diesel engine of a regular car is mainly determined by the characteristics of the tank.

The direction of the development of the tank since the beginning of the world is to fight farther, have stronger protection, and run faster. The third point will not be considered for the time being, and the first two points will be discussed. The farther you go, the more advanced artillery and fire control systems you need. More protection requires stronger armor.

Both of these points are making the tank heavier and heavier.

At present, the weight of mainstream main battle tanks is basically more than 60 tons. Being able to drive this weight, and being able to come and go freely in the battlefield environment, restricts, or rather lays the foundation for the main tone of its engine.

That is, power, revolutions, torque!

Needless to say, the power is a test of how fast the tank can run and how much it pulls. Torque, which represents the flexibility of the tank in combat and most importantly the ability to cross the country.

So in response to these two points, Li Fanyu and Wang Yu worked with the team to pull out a shelf.

Although he has no experience in the development of tank engines, he has just finished working on two diesel engines for off-road vehicles. So this shelf was quickly erected by everyone.

What's the usual way to pursue power and torque?

Increase the number of cylinders, increase the diameter of the cylinder block, increase the piston stroke!

That 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 letting an impotent man regain his strength, the same reason!
