I tinkered with cars and built a super military industry

"Fuel consumption is 100 liters per [-] kilometers?"

Yan Hua frowned and muttered to himself:

Twin-turbo V12 diesel engine, high power, [-] horsepower.

For this engine alone, the fuel consumption per 200 kilometers must be at least about [-] liters.

If you count the turbofan engine.

With dual engines working, the fuel consumption per 600 kilometers is upwards of [-] liters, which is absolutely reliable.

But Li Yifan said that the fuel consumption per 100 kilometers is only [-] liters.

This is a bit unreasonable.

But due to human feelings, Yan Hua did not express his doubts directly.

"Classmate Li Yifan, your tank is very well made."

"It is the most thoughtful design of any tank I have ever seen."

"But your engine design really exceeded my expectations."

"It's just a tank, but you actually used the F135-PW-100 turbofan engine from Country M."

"Though turbofan engines are used a lot in the aviation field."

"But for ground units, there are indeed very few or even none."

"For mobile units on the ground, reciprocating engines have many advantages over turbofan engines."

"Because the disadvantage of the turbofan engine is that whether it is at full speed or idle, the fuel consumption is quite alarming."

"For example, the fuel consumption of a turbofan engine at full speed is [-] percent."

"But when it is idling, its fuel consumption must reach [-] percent."

"The reciprocating engine is different. Only when the workmanship is larger, the fuel consumption will be greater."

"If you work at idle speed, the fuel consumption is almost negligible."

"So in countries that have turbofan engines on tanks, there are almost none."

"Even if there is, it is country M and country E, which have equipped two tanks."

"But because the problem of fuel consumption could not be solved, turbofan engines were basically not used in the end." Yan Hua said.

After hearing Yan Hua's words, Li Yifan didn't have much expression.

"They don't understand turbofan engines." Li Yifan said lightly.

Li Yifan's words almost made Yan Hua's eyes pop out.

What do you mean they don't understand turbofan engines? Others, Country M and Country E, are both the world's top military powers.

In the early days of China, we were always humble and shamelessly introduced other people's obsolete turbofan engines.

Then imitate, and then slowly surpass.

Yan Hua strongly suppressed the anger in his heart and said:

"Student, you said that the fuel consumption per 100 kilometers is only [-] liters. Do you have any technical theoretical knowledge to share?"

Li Yifan hates answering theoretical questions because he doesn't understand them either.

"There's a heat recovery device on the turbofan engine."

"This recuperator is a giant heat exchanger."

"The air coming through it is heated by the exhaust before entering the combustion chamber."

“Thereby reducing the heat signature of the exhaust and fully improving fuel efficiency.”

"Convert more heat energy back into the engine for secondary or tertiary heat conversion."

"Of course, another advantage of this is that the turbofan engine does not eject like a jet aircraft."

"Thereby reducing the heat signature and avoiding becoming a target for heat-seeking missiles."

Li Yifan followed the theory given by the system and explained it in his own easy-to-understand way.

Yan Hua, who was listening carefully, was stunned for a moment.

It turns out that turbofan engines can still be used in this way, and I have learned a lot.

See Yan Hua's appearance of discovering a new world.

Li Yifan shook his head in his heart. This was just the basic upgrade of the tank given by the system.

If a more advanced tank upgrade plan is unlocked, Yan Hua's jaw will probably drop in shock.

"Classmate, let's drag this guy out now and give it a try." Yan Hua said impatiently.

That's what Li Yifan originally thought.

He wanted to quickly take out this newly built tank and give it a try.

Firstly, he had never operated a tank before and was full of curiosity about tanks.

Secondly, this tank was completely built by himself, although with the help of the system.

But I still feel a sense of accomplishment in my heart, and I always want to test the weapons I made with my own hands.

Yan Hua called a heavy-duty tractor-trailer.

Drive the tank onto the trailer and cover the tank with a piece of black cloth.

Then Yan Hua and Li Yifan got on the tractor-trailer.

Perhaps because the tank weighs nearly [-] tons, the tractor-trailer was very careful when starting.

I'm afraid that the differential will be damaged if I'm not careful.

The tractor-trailer towed the tank and drove all the way to the outskirts of Haicheng for more than an hour.

Through the window, Li Yifan could clearly see that the outside was getting more and more desolate. It could be said that it was already a no man's land.

However, just when Li Yifan was curious, the tractor-trailer stopped on the side of the road.

"Academician Yan Hua, the test firing base has arrived." the tractor driver said.

"Well, okay!" After Yan Hua finished speaking, he got out of the car with Li Yifan.

Then he uncovered the black cloth of the tank and slowly drove off the trailer.

It may be because of the weight of the tank when it is dismounted.

The whole car body was shaking.

It seems that if you don't pay attention, the trailer will fall apart.

After getting off the tank, Li Yifan and Yan Hua entered the tank cockpit.

Li Yifan took control of the tank and opened the key.

Then there were rows of buttons and switches, all pressed on.

Finally, Li Yifan started the tank with excitement.

"Buzz!"

A roaring roar reached Li Yifan's ears through the cabin.

Let the blood in Li Yifan's body begin to expand.

This twin-turbo V12 engine is indeed several notches higher than a car's engine.

But obviously Li Yifan is not satisfied yet.

This tank has a twin engine, and the other turbofan engine has not been started yet.

The tank's dual engine setup can be started individually or both engines can be started simultaneously.

In order to have fun, Li Yifan chose to start the engines one by one.

At this time, Li Yifan placed his right index finger on the instrument panel on the right side of the steering wheel, a button with F2 written on it.

Then press without hesitation.

"Buzz!"

The roar of a turbofan engine reached the ears of Li Yifan and Yan Hua.

Unlike reciprocating engines, turbofan engines have a brief roar except for the moment they are started.

The sound that followed was like a jet engine, a sharp roar.

When Li Yifan and Yan Hua in the cockpit heard the sound of the turbofan engine, it sounded like a tank about to take off.

It made both of them feel hot.

Li Yifan shouted, "Sit down!"

Then step on the accelerator to the bottom.

"boom!"

The twin engines instantly reached over [-] rpm.

The nearly sixty-ton tank pounced out instantly like an awakened beast.

Yan Hua almost got thrown off his seat because he couldn't sit firmly.

The tank's instant acceleration really shocked Yan Hua.

This kind of tank speed has always been what he wanted to achieve.

Yan Hua thought that he would never see a tank reach such speed in his entire life.

I didn't expect that I would encounter such a fast tank in my lifetime.

In the future, the tank can change the iron turtle into an iron rabbit.
