The principle of the electric jet engine on the Viking drone is basically the same as that of the turbojet engine, and in a sense, it may be more figurative to call it "electric vortex jet".

People who don't know about aviation or military may think that jet engine must be very high-tech, but in fact this is not the case, the implementation principle of aircraft engine is not fundamentally different from that of automobile engines, and it is just a kind of "heat engine".

By the way, the early steam engine was also a kind of "heat engine", which relied on fuel, chemical energy or other energy to heat a medium such as water or air to expand it, push the mechanical structure to move, and finally convert it into mechanical energy.

This is how the steam engine works, the same is true of the engine of a car, and the same is true of the engine of a jet aircraft.

The difference is only in the different implementation methods, the different processing difficulties of the parts, the different requirements of the parts and the different complexity of the whole.

Although jet aircraft engines are called the crown jewels of modern industry, they still do not escape the level of elementary school textbooks in principle.

Its working process can be simply described as inhalation-compression-heating-jetting.

The direct injection of hot air is called a turbojet engine, or turbojet for short.

A turbofan engine is called a turbofan engine, referred to as a turbofan, when a "tube" is put on the outside of the turbojet engine and the hot air is allowed to pass through several stages of fans.

The advantage of turbofan engines is that they are more energy efficient and that the problem of higher drag at low and medium speeds is not obvious.

Of course, it seems that the advantages of turbofans are not great compared to turbojets? But on a planet that is still dominated by fossil fuels, the mere fact that it is more fuel-efficient is enough to make turbofans obsolete.

However, the design difficulty, processing difficulty and high material requirements of the turbofan engine are worthy of the "crown jewel".

Especially the last two, let alone the civilization on Earth, even Chen Zheng can't build a usable high-voltage fan now...... Of course, without the use of zero crystals.

The main problem is that alloys that are resistant to high temperatures, wear and tear and have a low coefficient of thermal expansion cannot be manufactured. Therefore, when the final engine was finalized, Chen Zheng could only choose the turbojet scheme.

The turbojet engine was born in 1930 and was invented by the Englishman Frank Whitt. Nowadays, even some aviation enthusiasts can DIY various turbojet engines at home, so you can imagine how mature such a design is.

Chen Zheng and his team used the same classic vortex jet structure, except that the fuel nozzle was eliminated in the combustion chamber and turned into an ultra-high-pressure arc generator.

As the compressed air passes through the combustion chamber, it is heated to nearly 4,000 degrees by an electric arc......

Not only that, but the enormous energy contained in the high-voltage arc even directly heats some components in the air into plasma!

When these hot gases containing plasma pass through the first section of the tail of the sound Viking fighter, the energy in the plasma will be absorbed, and when it passes through the second and third sections, the heat in it will be partially recovered by the thermo-electric conversion device, which will be converted into electrical energy and fed into the engine.

When Chen Zheng piloted the Viking fighter plane into the sky, several huge flying dragons bit the back of Chen Zheng's ass and chased after him.

Since the Viking drone was not designed with backward weapons, and the speed was relatively slow when climbing vertically, when Chen Zheng was about to enter the range of the flying dragon, Chen Zheng's fingers moved lightly and turned off the energy recovery device in the tail section 123......

Then, a thrilling scene happened.

The flame in the tail nozzle of the Viking fighter suddenly lengthened, and the point equilibrium of the plasma itself was broken and blown away in the intense turbulence, as the positively and negatively charged ions were separated more and more apart...... The discharge phenomenon has happened!

Countless electric snakes bloomed in the tail flames of the Viking fighters, tumbling and flickering......

The sound they make is not like the "click" sound of lightning or the "sizzle" sound of poor contact with household power supply, but rather a "rumbling" of thunder, which is low, muffled, and imperceptible.

"Ga ————"

A flying dragon crashed into Chen Zheng's wake unprepared, the scorching air was nothing, but the small electric current seemed to have found a relative, and surrounded it "enthusiastically"!

"Rumble Rumble......

With a low thunderclap, the wyvern was blackened by the electricity, and fell crookedly with convulsions, until it almost fell into the crater, and then it trembled on the cliff and couldn't fly.

The same fate did for several other wyverns.

Chen Zheng's ascent was no longer hindered, until he fell from the adjacent space where the air was thin, and he was already nearly a thousand kilometers away from the crater!

"Are you alright, sir?" The glasses man's voice was silent for a long time, and it wasn't until Chen Zheng left the area that he dared to ask.

"It's okay...... It's just that...... It's a pity. Chen Zheng sighed, "I didn't expect it to have developed so many flying dragons in such a short period of months......

“……”

The people in the base couldn't help but fall silent when they remembered that when Chen Zheng had just flown in, the dragons that rose into the sky like dark clouds.

In the face of such a powerful force as a natural disaster, it seems that any effort is in vain.

"I wanted to kill it by the way, but unfortunately...... If I had come two months earlier, ......" Speaking of this, Chen Zheng suddenly smiled bitterly, "Two months earlier, the Vikings haven't been built yet." ”

“…… What do we do next? The man in glasses asked everyone's thoughts.

"Take the initiative to attack, consume the number of wyverns, attack its resource-collecting worker ants, and use electromagnetic cannons to bombard the crater directly from high altitude!"

With Chen Zheng's clear words step by step, the eyes of the people who had begun to despair gradually lit up with hope again.

"Yes! My lord! The man with glasses said excitedly.

"Although our enemies are very strong, don't forget...... We still have a small one, and we have infinite wisdom and industrious hands...... Victory is ours. ”

……

When Chen Zheng returned to the base, he looked at the people who had become confident again, no
