I tinkered with cars and built a super military industry

the next day.

Li Yifan and Yan Hua arrived at the logistics department of the aviation power group early.

It has to be said that this aviation power group is indeed much higher than the specifications of the tank research and development group.

The logistics department alone has a constant flow of people coming and going.

Maybe because of the warehouse.

People who came here empty-handed ended up driving the operating truck and leaving with materials.

Of course there are those small pieces of material.

For such small items, you can either use your bare hands or use a small truck to haul them away.

At this time, Li Yifan followed Yan Hua, and the two quickly walked towards the window to apply for materials.

Although the area here is huge, Yan Hua is very familiar with the roads.

Yan Hua and Li Yifan came to the information application window.

Through the small hole in the window, he said to the staff inside:

"Little sister, bring me a ton of super aviation aluminum."

The girl staff member inside the window said without raising her head:

"Give me the application form!"

"No!" Yan Hua said confidently.

After hearing Yan Hua's voice, the staff looked up.

When they saw it was Yan Hua, the staff immediately frowned.

"Academician Yan Hua..."

After a fierce confrontation between the two sides, Yan Hua finally brought a ton of super aviation aluminum back to the tank research team.

……

In the small research room of the tank team, Li Yifan was wearing a white coat.

While watching the system's 3D video tutorial, I started to use it.

Considering the space problem in the research room, Li Yifan planned to manufacture the parts of the detonation engine first.

Compared with traditional turbofan engines, detonation engines have simpler components.

Because there are no turbofan blades or compressors.

The only thing that's the same is the combustion chamber.

But as far as the structure of this combustion chamber is concerned.

It seems simple, but in fact it hides many mysteries.

Just look at the structure diagram given by the system.

Rotary detonation engines and oblique detonation engines are designed together.

To be honest, this new type of engine surprised Li Yifan!

Compared with the reciprocating engine, this new type of engine has no piston and no compression cylinder.

Also compared to the turbofan engine, this new engine has no turbine or compressor.

In terms of workmanship, except for the intake and exhaust systems and the unique ignition system, there are no other moving parts.

Even though there are several similar systems, the working principles are completely different.

Li Yifan actually had no idea about manufacturing this new type of engine.

There are some systematic things that completely subvert some conventional concepts.

But if you think about it carefully, there doesn't seem to be much difference.

Traditional reciprocating and turbofan engines, as well as this new engine.

It is a mixture of air and fuel.

Then ignite the work, and then exhaust.

Their fundamentals have not changed.

The only thing that changes is the way of ignition and combustion.

But there is no doubt that the detonation engine has more power output.

The power of the detonation engine mainly relies on the explosion wave to generate thrust.

And it was a continuous wave of explosions.

Turbofan engines, including scram engines, rely on the conversion of fire energy into kinetic energy.

But their ignition to workmanship and exhaust are all linear.

This kind of linear power that continues to burn will lose even more power.

……

Li Yifan followed the 3D video tutorial steps to make the first mold of the detonation engine.

This mold is a cylindrical combustion chamber.

There are two end faces in the combustion chamber, one is closed and the other is open.

The closed end is not completely closed, and there is a circle of round holes on it.

According to the system prompts, these round holes are used to introduce the mixture.

This cylindrical combustion chamber is composed of an outer cylinder and an inner cylinder.

The inner cylinder extends from the air inlet end face to the open end face.

The function of this cylinder is the main structure of the rotating detonation engine.

When the mixture passes through a circle of intake holes, it enters the combustion chamber.

When ignited by a glow plug.

The entire combustion process will form a vortex combustion mode with the mixed gas in the combustion chamber.

And after burning, it is discharged into the atmosphere along with the cylinder in the combustion chamber.

This rotary cannon-type engine is a bit like Gatling in its workmanship, with continuous explosions.

After completing the mold of the rotating detonation engine.

Li Yifan then manufactured the mold for the oblique detonation engine.

The oblique detonation engine is even weirder than the rotary detonation engine.

The air inlet and combustion chamber are composed of two inclined planes.

The first bevel is a two-angle bevel, also called an air compression bevel.

The second slope is the combustion chamber, and there are detonation wave baffles on both sides of the combustion chamber.

But the most important thing is the first two-stage air compression ramp.

This is also the supersonic core device of this new engine.

When the mixture is compressed by two stages of air, it is then injected into the combustion chamber.

Then ignited by a spark plug, a detonation method will be formed.

This oblique detonation method is more powerful than the rotary detonation engine.

The power generated is stronger.

Once the oblique detonation engine starts, its speed will only get faster and faster.

In its eyes, the Mach Twelve of the Bald Eagle Country are completely scum.

But this oblique detonation engine has a fatal flaw, that is, it cannot accelerate from zero.

Its working environment must be at a speed of Mach 5 or above to function.

So it must be led by the former.

When the fighter is fierce, it can reach Mach 5, but the pilot cannot bear it.

It is impossible to use a fighter plane to fly an oblique detonation engine.

But now the system cleverly combines the rotating detonation engine and the oblique detonation engine.

That is to make up for the lack of early power of the oblique detonation engine in disguise.

And as far as the workmanship limit of the rotating detonation engine is concerned, it can reach Mach 5 to Mach 7.

After reaching this speed, starting the oblique detonation engine is a piece of cake.

Li Yifan did not make this oblique detonation engine mold into an assembly in one go like the rotary detonation engine.

Instead, it is divided into four parts, upper, lower, left and right, for processing.

The internal slope of the oblique detonation engine must be flat and smooth.

Otherwise, a lazy person like Li Yifan would definitely make it into an assembly in one go.

After the two detonation engine molds were made, Li Yifan threw a piece of super aviation aluminum into the boiler.

The high-temperature boiler instantly melts the super aviation aluminum.

Li Yifan looked at the 3D video tutorial on the system panel, which showed the boiler processing time.

When the 3D video tutorial panel prompts that it is ready.

Li Yifan directly used a large spoon to fish out the aluminum alloy dissolved in the boiler.

Pour directly into the molds of the two engines.
