I tinkered with cars and built a super military industry

Aeronautical Power Group of South China Military Institute.

Led by Zhang Xiang, all members of the aviation power team came to the laboratory.

This laboratory is located in the Aerospace Power Group, a secret underground base.

After everyone took the elevator to the underground, they walked through a bright corridor.

Then we came to an iron door made of heavy metal.

Zhang Xiang came to the door and placed his hand in the fingerprint unlocking area aside.

The fingerprint unlocking panel laser scanned the palm, and then the door rumbled.

The heavy metal door slowly moved open.

Judging from the way the heavy metal door is opened, it is definitely not light.

After the door was fully opened, Zhang Xiang led the way.

The crowd followed.

After entering the laboratory, it was a completely different world.

The interior space of this underground laboratory is very high and spacious.

Regardless of the wall, ceiling or floor, snow white is used as the background color.

The ceiling of the laboratory is full of high-brightness spotlights.

The light illuminates the entire laboratory, making it bright.

Moreover, under the combined arrangement of these spotlights, people standing in the laboratory can't see any shadows at all.

The shadowless lamp used by doctors in hospitals is the same as when operating.

There are several turbofan engines placed on the workbench in the laboratory.

The top of the turbofan engine is covered with many lines and tubes of various colors.

As soon as people enter this laboratory, they feel full of scientific research.

It's also the South China Military Institute, and the tank team's laboratory is made like a run-down factory building.

The research and development laboratory of the aerospace power group is so high-end.

After entering the laboratory, Zhang Xiang did not stop.

He led everyone through the laboratory and came to a heavy metal door.

Zhang Xiang changed to password unlocking this time and opened the heavy metal door.

There is another laboratory behind the laboratory.

The laboratory here is not as big as the laboratory outside.

But the equipment inside is obviously much more powerful than the equipment outside.

In addition to shadowless lamps, digital displays are also hung on the walls.

Various data are jumping all the time, as well as several waveform diagrams.

Under the digital display screen, Yunfan was attracted by an engine with a long tail pipe.

The reason why I recognized it was an engine.

It's because its appearance is somewhat similar to the original turbofan engine.

Yunfan came to the engine and looked at the turbofan engine with curiosity.

He looked back and forth at the engine.

The engine in front of me looks somewhat similar to a turbofan engine.

Its internal structure is completely different.

The turbofan engine's turbine and compressor are missing.

The only thing that is the same is the combustion chamber and exhaust tailpipe structure.

Even though the two structures are the same, their design principles are different.

The combustion chamber of the engine in front of you is integrated with the tail pipe at the back.

But the tail pipe is slightly smaller than the combustion chamber.

At the front end of the combustion chamber, an appropriate amount of mixture can be injected.

With the addition of the spark plug at the top of the combustion chamber, the entire engine structure is complete.

The structure of this thing seems to be countless times simpler than that of a turbofan engine.

At this time, Zhang Xiang came over and introduced Yunfan:

"Minister Yun, this is the latest pulse detonation engine we have developed."

"This side is the mixture air inlet, this is the explosion chamber, and this position is the ignition plug."

Yunfan nodded and said:

"Detonation engines, I've been exposed to them before."

"Not just me, but the entire aerospace power research community knows about this thing."

"But no results have been developed so far."

"Mr. Zhang, I know how the detonation engine works."

"Similar to detonation in a reciprocating engine."

"But the way a detonation engine works is that the blast wave creates thrust."

"Compared with deflagration and explosion wave, the latter is obviously several times stronger than the former."

"The only drawback is that the energy wave generated by the explosion is unstable."

"In fact, as long as such a problem is solved, the detonation engine we developed will definitely come out of the blue."

Zhang Xiang nodded while listening carefully to Yun Fan's speech.

"Minister Yun, we have solved the problem of unstable detonation waves you mentioned."

"This current pulse detonation engine can increase the speed of our fighter aircraft to Mach 5 to Mach 7."

Yun Fan frowned slightly after hearing this.

"Mr. Zhang, the power output of your pulse detonation engine is intermittent!" Yun Fan said.

"It's easy for Minister Yun to connect this single detonation engine with three to six."

"Using the control unit to control the ignition can solve the problem of inconsistent ignition that Minister Yun mentioned," Zhang Xiang said.

"Theoretically it can be achieved."

"Mr. Zhang, has this detonation engine of yours been installed and tested for flight?" Yun Fan asked.

"It has been tested with drones. As for fighter planes, it has not been tested yet."

"However, there are ready-made fighter jets that we can test fly at any time." Zhang Xiang said.

Yunfan frowned and looked at Zhang Xiang.

"Test flight anytime?"

"We are all flight attendants. For test pilots, a test flight is like stepping into the gate of hell with half a foot."

"Mr. Zhang, where are your pulse detonation engine test parameters?" Yun Fan asked.

"Yes!" After saying that, Zhang Xiang asked someone to hand over a portfolio.

The file bag contains drawings of the pulse detonation engine and various wind tunnel test data.

Yunfan read through all these information and data.

If there was anything he didn't understand, Yun Fan would immediately point it out without swallowing it all.

This carefulness and persistence is a habit developed by every fighter design engineer.

As a fighter aircraft design engineer, you must be responsible for the fighter aircraft you design.

All imaginable and imaginable issues must be studied carefully.

This is also the responsibility of the test pilot.

An hour later, Yunfan finished reading the information and came to the fighter plane equipped with a pulse detonation engine with Zhang Xiang.

This fighter plane has a single cabin, which is slightly different from ordinary fighters and is darker in color.

The design of the entire fuselage is somewhat rounded, and the lines do not look so sharp.

The aerodynamic layout adopts a canard type.

The lift center of gravity is tilted backward.

The power is a pulse detonation engine developed by Zhang Xiang and others.

The main wing is a delta wing.

The vertical tail is a double vertical tail.

Compared with the previous generation fighter, the changes are relatively large.

The fighter jet circled around the cloud area no less than ten times.

Every corner of the fighter plane was inspected.

There is no way, even if he is upgraded now, the blood of fighter designer still flows in his bones.

When I see these planes parked in the field, I will habitually go up and check the planes several times.

There is no way, as an engineer and a maintenance man.

The fighter planes I was responsible for were checked hundreds of times before taking off, and everything was normal.

"Mr. Zhang, please check again. After the inspection, prepare to arrange a test flight..."
