Movie black technology

Streamline body ......

The black antelope that with a gold bar like the body at a glance with the word streamline can not be related to the two words.

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

The four sets of nano-plasma boosters are naked on the outside, and also have nothing to do with these five words.

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

Just as Chen Shen said, the main reason why the Black Antelope does not adopt the two design criteria of the general airplane is the speed.

Because the Black Antelope's cruising speed in the atmosphere is only 5803 kilometers per hour, a good distance from Mach 6's 7350.48 kilometers, it can't exceed 7,000 kilometers even if it is traveling at top speed.

Just close to six thousand kilometers per hour, with the Black Antelope currently this non-integrated design of the large bird structure still holds up, will not fly and suddenly disintegrate in the air.

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 compatible with the structure of the nuclear reactor. It can be said that the upper, lower, left, right and front of the fuselage, in addition to the rear and side doors and windows of the cabin, the other parts have nuclear reactor components, and the passengers inside are sitting in the middle of the reactor envelope.

This is also the limit of the size of the current nuclear reactor can be reduced, so directly on the wing plus four sets of booster units can carry the fuselage to fly.

This is the most economical solution, the one with the smallest fuselage size, and the one that fits its status as an attack aircraft.

If a streamlined shell is added to the Black Antelope, there are more things to consider, and the larger fuselage size will require a larger field for takeoff and landing, while the increased fuselage weight will waste engine thrust.

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

Chen Shen looked at the top of the screen and continued, "The Black Antelope is different from a normal space plane in that the plasma pulse thrusters can ensure that it will not experience thrust decay during flight, so it does not need to reach hypersonic speeds to leave the atmosphere."

If an object can guarantee that it can sustainably generate enough momentum of its own to overcome gravity, then it can eventually fly away from Earth, no matter what its speed is.

That's what happened with the Black Antelope.

Only the airplane can not do it, in general they must rely on the general engine to reach more than three times the speed of sound, and then switch to the ramjet engine to propel itself to the edge of the atmosphere, until it can no longer get oxygen from the outside world, and then activate the rocket engine, using the liquid oxygen and liquid hydrogen carried by itself as propellant to enter space.

Professor Li Songshu immediately said, "Such a good method can be thought of by anyone, but the problem is that you can really realize the pulse plasma thruster you mentioned?"

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

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

Then why finally return to the top of the chemical propulsion idea?

It is not because that engine can not be built!

Plasma propulsion is not a new thing, this device is, frankly speaking, a certain propellant ionized plasma, and then the plasma accelerated spray out, so as to obtain the reaction force.

It's the same as the plasma cannon on the Red Storm.

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

And this device is indeed, in theory, in the atmosphere and space environment can be used propellers, is a variety of science fiction films inside the regular guest, the film inside the engine blue light of the vehicle is the use of plasma thrusters.

But the problem is that, unlike the gun on the crimson storm, this engine can provide too little thrust in normal times!

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

With the current situation, the thrust generated by a normal person blowing his breath is greater than the thrust of most plasma thrusters.

Currently the most powerful plasma thrusters can only produce 5.4 Newton thrust, that is, less than a kilogram, even it can not push itself.

The biggest highlight of this engine is the long working time, moving tens of thousands of hours of operation, is really a representative of the drop through the stone.

So their use is generally in the satellite after the sky, and then go to the satellite "blow", so that the power provided in a vacuum environment for a day is enough to accelerate the satellite a dozen or 20 meters, you can keep the satellite flight speed or change orbit.

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

He turned the tables and began to take the initiative to explain the idea of the set of plasma thrusters on the Black Antelope.

Although the details released by the system now were only for the miniature nuclear reactor, he had built a plasma cannon and his understanding of the plasma field was not shallow.

Together with the technical outline provided by the system, combined with the official name of "nano-plasma pulse propulsion unit", it was easy to guess the specific idea.

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

Chen Shen gestured with both hands: "I envision a single plasma propulsion unit will be formed by at least 500,000 thrusters, and the size of each ion thruster is the same as what you have written in the document, the nanometer level."

When he said this, the people over the screen really lowered their heads to look at the document, only to see that it is indeed written "nano-plasma pulse propulsion unit".

Only now did the crowd understand what the word nano hanging in front of them meant.

Chen Shen continued, "The 500,000 nano ion thrusters will rapidly ignite multiple times, ejecting plasma multiple times, giving each propulsion unit at least 17 tons of thrust."

Pulsed propulsion unit, pulsed here means continuous ignition ionization of the propellant.

Each time the propellant is ionized to produce plasma, immediately after the thrusters eject it, the propellant is ionized again to produce plasma again and eject it ......

This cycle is repeated so quickly that although the plasma jet appears to be continuous on the outside, it is actually intermittent, except that the interval is almost zero, which is why it appears to be continuous.

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