Movie black technology

Streamlined body...

The black antelope's fuselage, which looks like a gold bar, has nothing to do with the word streamline at first glance.

integrated design……

Four sets of nano-plasma boosters were placed outside naked, and they also had nothing to do with these five words.

From these two perspectives, the design of the Black Antelope is completely opposite to the current mainstream.

It's just that, as Chen Shen said, the main reason why the Black Antelope does not adopt the two design standards of general aerospace aircraft is its speed.

Because the cruising speed of the Black Antelope in the atmosphere is only 5803 kilometers per hour, there is still a long distance from the 7350.48 kilometers of Mach 6. Even if it travels at the highest speed, it cannot exceed 7,000 kilometers.

With a speed of only close to 6,000 kilometers per hour, the Black Antelope's current non-integrated design of the big bird structure can still hold up, and it will not suddenly disintegrate in the air while flying.

As for why the fuselage is not streamlined, one is the structural design of the nuclear reactor, and the other is to improve the utilization of internal and external space and thrust.

The fuselage of the black antelope is highly consistent with the structure of the nuclear reactor. It can be said that the upper, lower, left, right and front of the fuselage, except for the rear door, side door and windows of the cabin, other parts have nuclear reactor components. The passengers inside are surrounded by the reactor. .

This is also the limit of the current size of this type of nuclear reactor that can be reduced, so adding four sets of booster units directly on the wings can carry the fuselage and fly.

This is the most trouble-free solution, and it is also the solution with the smallest fuselage size, and it is also a solution that conforms to its identity as an attack aircraft.

If a streamlined shell is added to the black antelope, there will be more things to consider, and the size of the fuselage will become larger, and the requirements for take-off and landing sites will also increase. At the same time, the increased weight of the fuselage will waste the thrust of the engine.

Although it can increase its speed in the atmosphere, it is meaningless for a space attack aircraft to only increase the speed in the atmosphere.

Chen Shen looked at the people on the screen, and continued: "The Black Antelope is different from ordinary aerospace planes. The plasma pulse thruster can ensure that it will not encounter the problem of thrust attenuation during the flight, so it does not need to reach a high level. The speed of sound can also leave the atmosphere."

If an object can ensure that it can continue to generate enough power to overcome gravity, then no matter what its speed is, it will eventually fly away from the earth.

This is the reason for the black antelope.

It's just that aerospace planes can't do it. Under normal circumstances, they must rely on ordinary engines to reach more than three times the speed of sound, and then use ramjet engines to propel themselves to the edge of the atmosphere. When they can no longer obtain oxygen from the outside world, they will use rocket engines. , using its own liquid oxygen and liquid hydrogen as propellants to enter space.

Professor Li Songshu immediately said: "Anyone can think of such a good method, but the question is, can you really realize the pulsed plasma thruster you mentioned?"

The old man who spoke just now also looked at Chen Shen, waiting for his answer.

As long as there is continuous power, you can go to space, that is to say, you can go to space as long as you have a propeller that can be used in the atmosphere and in space. Scientists on earth have already thought about this idea.

So why go back to the idea of ​​chemical propulsion in the end?

Isn't it because that kind of engine can't be built!

Plasma propulsion is nothing new. To put it bluntly, this device is to ionize a certain propellant out of the plasma, and then accelerate the plasma out to obtain a reaction force.

Just like the plasma cannon on Crimson Storm.

In essence, it is still the set of relying on spitting out the medium to obtain the reaction force to propel the flight.

And theoretically speaking, this kind of device is indeed a propeller that can be used in the atmosphere and space environment. It is a frequent visitor in various science fiction films. The aircraft with blue light from the engine in the film uses plasma propulsion.

But the problem is that, unlike the cannon on Crimson Storm, the thrust that this engine can provide in normal times is too small!

Because the medium it throws out is an atom, the reaction force that can be obtained in this case can be imagined...

Judging from the current situation, the thrust generated by a normal person's breath is greater than that of most plasma thrusters.

At present, the most powerful plasma thruster can only produce a thrust of 5.4 Newtons, which is less than one kilogram, and it cannot even push itself.

The biggest bright spot of this kind of engine at present is the long working time, which can run for tens of thousands of hours at every turn, which is really a representative of dripping water and rocks.

Therefore, their purpose is generally to "blow air" on the satellite after the satellite is launched into the sky, so that the power provided by the satellite in a vacuum environment is enough to accelerate the satellite by ten or twenty meters, allowing the satellite to maintain its flight speed or Change track.

Regarding Professor Li's question, Chen Shen nodded readily: "No problem, I have a general idea now."

Instead, he took the initiative to explain the idea of ​​the plasma thruster on the black antelope.

Although the detailed information released by the system is only about miniature nuclear reactors, he has made plasma cannons and has a good understanding of the plasma field.

Coupled with the technical outline provided by the system, combined with the official name of "nano-plasma pulse propulsion unit", the specific idea can be easily guessed.

"The biggest difference between the plasma thruster I imagined and the current mainstream ion thrusters is the difference in volume."

Chen Shen gestured with both hands: "The single plasma propulsion unit I imagined will be composed of at least 500,000 thrusters, and the size of each ion thruster is the same as what is written on the current document, which is nanometers. level."

When he said this, the people on the other side of the screen really lowered their heads to look at the document, only to see that it did say "nano-plasma pulse propulsion unit".

Only now did everyone understand what the word "Nano" hanging in front of it meant.

Chen Shen continued: "These half a million nano-ion thrusters will ignite rapidly and multiple times, eject plasma multiple times, and provide each propulsion unit with a thrust of at least 17 tons."

Pulse propulsion unit, where the pulse means continuous ignition and ionization of the propellant.

Every time the ionized propellant generates plasma, after the thruster ejects it, it will ionize the propellant again, generate plasma again and eject...

Such a rapid cycle repeats, although the jet of plasma appears to be continuous on the outside, it is actually intermittent, but the interval is almost zero, so it looks continuous.

The biggest advantage of this propeller is that it can be started instantly, the response time is extremely fast, and no preheating is required.
