Streamlined body ......

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

All-in-one design ......

The four sets of nano plasma boosters were put naked outside, and they also have nothing to do with these five words.

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

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

Because the Cruising Speed of the Black Antelope in the atmosphere is only 5,803 km/h, it is still a long way from Mach 6 of 7,350.48 km, even if it travels at the top speed, it cannot exceed 7,000 km.

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

As for why the fuselage is not streamlined, the first is the structural design of the nuclear reactor, and the second 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 up, down, left and right sides of the fuselage and the front, except for the back and side doors of the engine room and the windows, there are parts of the nuclear reactor in other parts, and the passengers inside are sitting in the reactor surrounding.

This is also the limit of the size that can be reduced by the current type of nuclear reactor, so four sets of booster units can be added directly to the wings to 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 in line with its identity as an attack aircraft.

If you add a streamlined shell to the black antelope, there are more things to consider, and the size of the fuselage will become larger, the requirements for the take-off and landing site will also become larger, and the increased weight of the fuselage will also waste the thrust of the engine.

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

Chen Shen looked at the person on the screen and continued: "The Black Antelope is different from ordinary aerospace aircraft, the plasma pulse thruster can ensure that it will not encounter thrust attenuation problems during flight, so it does not need to reach hypersonic speed to leave the atmosphere. ”

If an object can sustain enough power to defy gravity, it will eventually be able to fly away from the Earth, regardless of its speed.

That's the case with the Black Antelope.

It's just that aerospace planes can't do it, and under normal circumstances they have to rely on ordinary engines to reach more than three times the speed of sound, and then switch to ramjet engines to propel themselves to the edge of the atmosphere, until they can no longer get oxygen from the outside world, and then turn on rocket engines to use their own liquid oxygen and liquid hydrogen as propellants into 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 are talking about?" ”

The old man who had just spoken also looked at Chen Shen at this time, waiting for his answer.

As long as there is continuous power, you can go to space, that is, as long as you have a thruster that can be used in the atmosphere and in space, you can go to space, and scientists on Earth have long thought about this idea.

So why do we have to go back to the idea of chemical propulsion in the end?

It's not because that kind of engine can't be built!

Plasma propulsion isn't a new thing? To put it bluntly, this device is to ionize some kind of propellant out of the plasma? The plasma is then ejected at an accelerated rate to obtain the reaction force.

It's like the plasma cannon on Crimson Tempest.

In essence, it is still a set of flying by spitting out the medium to obtain a reaction force to propel the flight.

And this device theoretically? Is it indeed a thruster that can be used in both the atmosphere and the space environment? is a frequent visitor in various science fiction films, and the aircraft with blue light engines in the film uses plasma thrusters.

But the question is? Unlike the cannon on Crimson Tempest, this engine can provide too little thrust in normal times!

Because the medium it throws is an atom? The reaction force that can be obtained in such a situation can be imagined......

As it stands? The thrust produced by a normal person's breath is greater than that of most plasma thrusters.

The most powerful plasma thruster at the moment can only produce 5.4 Newtons of thrust, or less than a kilogram, and it can't even push itself.

The biggest highlight of this engine is the long working time, tens of thousands of hours of operation time at every turn? It is a representative of dripping water through stones.

So their use is generally after the satellite is in the sky? Then go to "blow" the satellite, so that the power provided in the vacuum environment is enough for the satellite to accelerate by more than ten or twenty meters, so that the satellite can maintain its flight speed or change orbit.

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

Is he anti-guest-oriented? began to take the initiative to explain the idea of the plasma thruster on the black antelope.

Although the details of the system are now only available for miniature nuclear reactors, he has ever built a plasma cannon? The understanding of the plasma field is also not shallow.

Plus the technical outline provided by the system, combined with the official name of the "Nano Plasma Pulse Propulsion Unit"? It's easy to guess the specific idea.

"The biggest difference between the plasma thruster I envisioned and the current mainstream ion thruster is the difference in size."

Chen Shen gestured with both hands: "I envision that a single plasma propulsion unit will be composed of at least 500,000 thrusters, and the size of each ion thruster is the same as what you write on the current document?" It's nanoscale. ”

What did he say? The people on the other side of the screen really lowered their heads to look at the documents? I saw that it was indeed written "Nano Plasma Pulse Propulsion Unit".

Only then did everyone understand the meaning of the two words nano hanging in front of them.

Chen continued: "The 500,000 nano-ion thrusters will ignite quickly and multiple times, eject plasma multiple times, and provide at least 17 tons of thrust to each propulsion unit. ”

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

Each time the propellant is ionized, plasma is produced, and immediately after the thruster ejects it, the propellant is ionized again, and the plasma is produced again and ejected......

The cycle repeats so quickly, and although it looks like the plasma is continuous on the outside, it is actually intermittent, but the interval is almost zero, so it appears to be continuous.

The biggest advantage of this thruster is that it can be activated instantaneously, and the response time is extremely fast, and there is no need for warm-up.
