After making up his mind, Li Fanyu went straight to the point.

"Old Lu, since you trust me and come to Tiancheng at this critical moment, I have to work hard no matter how hard I want. Just tell me what the requirements of this engine are."

"I just like the spirit of you young people! You dare to fight and fight, okay!" Lu Mingde patted the handrail of the sofa, looking very excited.

"The specific parameters are too complicated. Let's not talk about it and let the institute send someone to communicate with you. I will talk about the most important things."

"Okay, you said!"

"Reliability! To ensure the best reliability while trying to ensure performance! Xiao Li, to be honest, we can't figure out this diesel engine.

Since we have said that, I will tell you a solid foundation. We have already developed a set of engines based on 150bh.

However, the performance in high temperature and high cold was not satisfactory, and during the actual car test, several shutdowns and stops occurred within 30 minutes after cold start.

We have analyzed and improved this situation many times, but it has not been solved. You are a car and you know what this situation means."

Hearing this inside story, Li Fanyu nodded heavily.

This represents a serious design flaw!

The sudden shutdown of the engine at work is definitely an untolerable problem, let alone a tank, putting it on a car is definitely an unwilling problem. If the engine is shut down while running on the highway, it will not be started no matter how hard it is to start. You can imagine what the consequences will be.

To put it in a bit extreme, if the tank suddenly shuts down during the battle, the entire vehicle will become the targets of enemy tanks or anti-tank missiles!

The first thing Mr. Lu said is reliability, which Li Fanyu absolutely agrees with. Whether an engine is good or not is another matter. It is basic and most important to be able to work stably without losing the chain!

Since tanks have become the king of land warfare, they represent the main weapon in modern army operations. All countries have invested a lot of energy in this area, and they spare no effort to improve the performance of tank engines.

In order to pursue the best power, some countries even use gas turbines to install them on tanks. What is a gas turbine? Lightweight ones are called aircraft engines, while heavy ones are ship engines!

This is a good choice, but in terms of performance, it looks much stronger as the diesel engine!

Is this motivation strong?

As it turns out, the best one is the right one. A gas turbine is not very powerful on a tank.

Two lunatics who placed the gas turbine on the tank, one was named Damao and the other was named Yingshang.

The t-80u of the Damao family uses gas turbines as tank power. At that time, Valeri Molozov, a gas turbine expert at the Damao family, believed that gas turbines were superior to diesel engines in many aspects.

For example, the engine is fast and there is no need to preheat. For example, the gas turbine will not shut down in extreme conditions. For example, the gas turbine has a large unit power and a higher unit output power than a diesel engine, which can make the tank faster.

For example, gas turbines do not need heat dissipation, which can save the bulky air-cooled system or water-cooled coolant supply device, and the gas turbine is easy to maintain, has a longer life, etc.

But the t80u equipped with a gas turbine was stunned when he arrived on the battlefield.

The working principle of a gas turbine is to drive the impeller to rotate at high speed with continuously rolling gas. This working state determines that the power output of the gas turbine is linear. That is to say, its speed peak value and valley value are not much different.

To put it bluntly, this working state is;

Gas Turbine: No matter how fast you want to run, controlling the speed is a matter of the gearbox. I just turn so fast and do whatever you want!

To put it bluntly, even at idle speed, the speed of the gas turbine is quite high.

What does this mean?

Gas Turbine: I know you want to say that I am an oil tiger! Get out!

That's right, it's just a tiger.

Modern warfare is no longer the era of large-scale rapid advancement of armored legions in World War II, but is evolving towards the direction of smaller and smaller combat scope and increasingly fierce local warfare.

Such a war situation makes the terrain of the battle narrower and more varied. City and street fighting have become a common way of fighting in contemporary wars. This way of fighting also requires tanks to stop and stop with the cooperation of infantry.

However, gas turbines cannot meet such demands. In street fighting and urban battles with high intensity and high recharge difficulty, the disadvantage of gas turbines' huge fuel consumption alone covers up all its advantages.

In the Chechen War in 1996, the T-80u on the streets and alleys of Grozny's city has fully confirmed this.

After all the fuel is exhausted, even with high-intensity armor, the t-890u will still become a living target for anti-tank bombs.

In addition, its combat capability is only 10% higher than that of diesel engine tanks, but its cost is 85% higher, making the tank that the t-80u, which has high hopes for, a joke and a short-lived ghost.

That is, those who have never seen the world like Beibang hold the t-80u that comes to pay off debts as a treasure.

Although the M1 main battle tank of Eagle Sauce encounters gods and kills gods and Buddhas on the Iraqi battlefield, it is known as the strongest main battle tank of Blue Star.

But two things need to be clear;

First, what kind of war is Iraq?

Second, how powerful is the logistics support in the United States?

A master who is not short of money will fight a food abuse battle where a full-level six-god apparel is used to kill a first-level Dolan Sword elementary school student. What is the performance of a weapon important?

It doesn't matter, money can make up for everything.

Weapons that do not depend on the cost of use are all rogues. Who on Blue Star is rich enough to fight with weapons using Hawkstone? Small fights are called advanced technology, and large-scale wars are called forced to death.

The technology used in tanks for light gas turbines is not yet mature, and repairing various faults is also a very headache.

You should know that gas turbines have extremely strict requirements on material and process. Because of its compact structure compared to diesel engines, maintenance is also a big problem.

Accessories are expensive and difficult to repair.

These two points are another fatal disadvantage on the battlefield.

The best ones are suitable and reliable!

,

This is the weapon research and development concept that China has always adhered to.

So Li Fanyu nodded repeatedly about this point raised by Mr. Lu.

"Don't worry, I've written it down, I'll start with this."

Lu Mingde nodded, "Xiao Li, you are a capable young man and a dedicated entrepreneur. We will give you the heart of our fourth generation main battle tank."

"Old Mr. Lu, don't worry, I will do my best to get this done for you!" Li Fanyu said solemnly.

Seeing Lu Mingde nodding and applauding, Li Fan's eyes turned and said, "Old Lu, how much research and development expenses can you pay this time?"

Lu Mingde raised his eyebrows, "Well, I won't give it to you this time."

"What?! Last time, qs15 gave 500 million, what happened this time?"

Looking at Li Fanyu who was on the verge of foot, Lu Mingde smiled: "Last time, I felt that the money was a bit big. How much did you spend on R&D for the 500 million boy?"

"Uh..." Li Fanyu said in a mess.

It took less than 100 million to exchange qs15 in the space, but less than 10 million in the R&D process.

But that’s not my relying on black technology drawings! If I do research and development from scratch, it would be considered a burning fragrance if I could stop with 500 million yuan!

Looking at Li Fanyu with a look of "I'm stinging!", Lu Mingde smiled and shook his head;

"In the past, our weapons research and development were mainly military science institutions and military-industrial enterprises. Although it is relatively controllable, it is inevitable to think in a fixed-line manner. Now the assembly is undergoing reforms, and we want to open orders to capable private enterprises similar to the Boeing model of the United States to participate in our arms research and development.

Your righteous faith is the first pilot.

If you complete the fourth-generation tank engine project successfully, this matter will be promoted as a typical example... Do you think it is worth more than 500 million? Xiao Li, it depends on the long term."

You are the second major in the long run...!

If you don’t give money, you will say you won’t give money. It’s useful to go so far!

Li Fanyu wiped his nose hard and stood up suddenly, "Old Lu, you know, we Zhengxin is not rich either. We just built an industrial base a while ago and invested more than 60 billion yuan. Then we developed three cars in a row, but the cost has not been recovered yet. We are short of money. Now we are working on a car model. The progress is as slow as a snail. We can't give it more or less?"

Lu Mingde looked at the guy's indignation and smiled and said, "I really can't."

"That's right, Mr. Lu, I'll take this job."

The big chimney next to it was smoking violently coughing - choking.

Li Fanyu shrugged helplessly as he saw this guy crying.

You have to do it if you don’t pay... Long-term meal tickets are in front of you, and you have to overcome difficulties!
Chapter completed!
