Lan Nuo chose to join the reconnaissance team, which is a boost to the morale of the entire human race. However, it will take a long time for the reconnaissance team to have real contact with the Trisolarans, and it will take nearly fifty years of sailing.
Can catch up with the Trisolaran fleet.
Considering that the acceleration process of a spacecraft modified by an accelerator is not that fast, even if the spacecraft can be accelerated to ten percent of the speed of light, it will take a long time, and it may not be possible to reach it in fifty years.
Therefore, humans still need to carry out their own construction before receiving intelligence feedback. In fact, it takes a long time for a spacecraft to fly out of the solar system.
Before the first batch of human space colonization spacecraft arrived at Jupiter, the reconnaissance spacecraft had already set off. For human interstellar spacecraft, this was a serious premature birth.
If the ecological cycle system was not stable enough and could maintain operation for a long time even if it was lost in space, I am afraid that humans would not launch the first fleet at all.
The second batch and the third batch of fleets that will be launched next will be launched one and a half years later respectively. By that time, human spacecraft manufacturing technology will be much more mature, and they will be launched exclusively from the corresponding star ports.
Drawing on the experience of Earth orbit accelerators, humans are preparing to establish an acceleration orbit in space, which is somewhat similar to the Ladder Plan.
The ladder plan in the original work was an attempt to use the lightest aircraft to send a human brain to the Trisolaran fleet before humankind's technological breakthrough.
The plan was carried out through nuclear explosions. At that time, humans had not yet separated from the working medium, and there was no technology to accelerate the spacecraft, and there was no controllable nuclear fusion to provide huge energy.
Accelerating a man-made spacecraft to one percent of the speed of light was a luxury for humans at that time.
Therefore, a very extreme method was adopted during the launch of the spacecraft, which was to place nuclear bombs one after another on the trajectory of the spacecraft, and then detonate the nuclear bombs after the spacecraft passed by.
There is a huge sail on the aircraft, which is made of nanomaterials. When unfolded, it looks like a parachute. It pulls the spacecraft equipped with a brain through slender cables. The energy of the nuclear explosion will impact on the huge sail and be converted into energy again and again.
A powerful propulsion, after multiple explosions, can theoretically accelerate the spacecraft to one percent of the speed of light.
The space acceleration orbit that humans are currently preparing to build is actually somewhat similar to this principle. To be precise, it is actually a huge electromagnetic gun, except that it is built in space and used to accelerate the spacecraft.
Just like the high-energy particle collider in space, their structure is also very simple. They are rings built one by one in space. They can propel the spacecraft through electromagnetic force. The rings are not connected to each other.
, just accelerate the spacecraft in this way.
There is a considerable counterweight on each ring to ensure that the reaction force generated by pushing the spacecraft in space will not cause too much displacement of the ring.
After a launch, the thrusters on the ring will recalibrate their position to complete the return of the ring position.
After doing this, the second round of launch can be carried out, because the ring itself is powered and can adjust its position in space, change its orbit, and launch the spacecraft in any direction.
In the past, spacecraft acceleration relied more on gravitational slingshots, but in a real interstellar war, these spacecraft that must rely on the planet to accelerate are obviously too backward.
Compared with planets, electromagnetic coils that can be built in large numbers in the solar system and move freely are obviously more suitable as a platform for accelerating spacecraft.
The speed that each coil can increase is not much, but when the coils are accelerated one after another, the propulsion efficiency is much higher than the propulsion efficiency of the spacecraft itself.
Some of these huge electromagnetic coils are distributed in the orbit of Jupiter. In the high orbit of Jupiter, a huge circular accelerator has been established. The accelerator can accelerate the spacecraft and high-energy particles. When accelerating the spacecraft, the spacecraft will orbit Jupiter.
The high-orbit and high-speed flight can continuously accelerate multiple circles, maximizing the utilization efficiency of the electromagnetic coil. Each electromagnetic coil can provide acceleration multiple times.
But there is a flaw in such an accelerator. That is, its acceleration has an upper limit.
The reason is very simple. To perform high-speed circular motion, you need to withstand a large centripetal force. This is how the simulated gravity of the ecological roller comes from.
By doing this calculation, you can know that even if the accelerator is built in a synchronous orbit, once the acceleration reaches about 1.4 times the angular speed of Jupiter's rotation, it is equivalent to having to withstand the gravity of Jupiter's synchronous orbit. The higher the acceleration speed, the greater the need to withstand.
The gravity will be greater. And with the current technology of mankind, there is far no way to offset this gravity.
In this case, the upper limit of acceleration is actually very low. Although it is higher than the upper limit of acceleration using a gravitational slingshot, this speed is still almost meaningless if you want to achieve interstellar navigation.
That's why there are accelerators that exist outside the orbit of the planet. They are no longer arranged in a ring, but will be arranged in a straight line as much as possible. On this line, there will be no problem of centripetal force, and only one
By accelerating the spacecraft several times, you can increase the speed of the spacecraft almost unlimitedly.
But equally, this means that each acceleration ring can be used at most once, and the acceleration efficiency is much lower.
Therefore, when humans need to accelerate a spacecraft, they usually use two methods at the same time. An acceleration ring is used to build an acceleration channel between the orbit of Jupiter and the orbit of Saturn. At the same time, a ring-shaped channel is established in the synchronous orbit of Jupiter.
Accelerate track.
The spacecraft will first accelerate to the limit that the astronauts can withstand, and then leave the circular acceleration orbit and enter the linear acceleration orbit. The electromagnetic coil here is larger, more powerful, and has extremely strong instantaneous power.
Every time the spacecraft passes through an electromagnetic coil, the coil will instantly consume a large amount of energy, strongly accelerating the spacecraft. After hundreds of acceleration rings, even a spacecraft without any power of its own can easily exceed the speed of the third universe and fly.
Out of the solar system.
…
"This is the prototype of the project I will be responsible for building next." Lannuo 03381 explained. He is the successor of the Wallfacer. Out of respect for Lannuo, his "will" has been well executed.
His first clone inherited his original position and some rights, and it turns out that, as he said before he left, the clone and the original body have almost exactly the same abilities. After inheriting
After taking the position, he did not let anyone down, successfully led mankind and continued the technological explosion.
"Can you describe the content of the project in detail? The spacecraft highway between the orbits of Jupiter and Saturn is still under construction. Our colonial spacecraft has just arrived at Jupiter. Many of the acceleration rings were modified on-site by the spacecraft.
, If we want to continue deep space construction, it may be difficult to do it with our current aerospace resources." Joshua has begun to have some headaches about the huge resource consumption of solar system defense construction.
"This is a long-term plan, and there is no need to rush. Jupiter's orbital accelerator actually gave us a good inspiration. Circular orbital accelerators are still more affordable than linear accelerators. Each acceleration ring can provide the spacecraft with more benefits.
times acceleration, which allows us to build fewer acceleration rings and achieve higher speed acceleration effects.
And why does this accelerated orbit have to be arranged along the planet?
No one has ever considered whether this kind of accelerated orbit can be arranged with the star as the center of the circle?
The circular acceleration orbit on Jupiter has given us a hint that in such an orbit, there is an upper limit to the speed of acceleration. The faster the orbit, the greater the acceleration it needs to endure.
Therefore, the larger the circle we draw, the higher the upper limit of acceleration. Correspondingly, we can use more energy to accelerate the spacecraft instead of correcting its flight trajectory to maintain a circular flight trajectory.
As for the acceleration orbit with the sun as the center, the orbit radius is much larger than the orbit with the planet as the core. It is almost not an order of magnitude. When accelerating in such an orbit, the upper limit of the speed is also higher than what we have now.
The upper limit is high, and interstellar travel can even be directly achieved after acceleration is completed.
I think such an accelerating orbit is necessary. Considering that our productivity is still relatively limited at present, we can first build an accelerating orbit in the inner circle of the Earth's orbit. We only need to build a space station at the Lagrange point of the Earth, and then
After completing the construction of the accelerating ring in the space station, and then launching it with very little power, it can move in the inner orbit of the earth. Because its angular speed is faster than that of the earth, it can naturally surpass the earth little by little.
In this way, as long as we ensure that the time interval between the creation and release of each accelerating ring is the same, the distance between each accelerating ring will be almost equal, and we do not even need to spend much resources to adjust their positions in space.
This is by far the cheapest way to build an accelerating orbit around a star. After building a small space station relying on these accelerating rings in the future, we can also rely on this space highway to build an accelerator around the sun. At present, we are not in the race yet.
We defeated the Trisolarans, but after winning, there is no doubt that such an accelerator is necessary.”
After a certain degree of demonstration, the Planetary Defense Council found that this was indeed a very feasible plan, and even less difficult to implement than establishing an accelerated orbit between the orbits of Jupiter and Saturn.
After all, it is closer to the earth, the real industrial base of mankind. Whether it is producing an accelerating ring or transporting the accelerating ring to the corresponding orbit, the difficulty is much lower.
Especially after a large number of space elevators have been built one after another, it has become easier and easier to transport materials from the ground to space. There is no need to specially launch the accelerating ring to the corresponding position at all. You only need to wait for the revolution of the earth to reach the corresponding position.
position, and then release the acceleration ring. The engineering difficulty can be said to be very low.
Once built, the acceleration limit will be incredibly high, and if it can be transformed into an orbital accelerator around the sun, the cost of accelerating high-energy particles will be reduced to cabbage prices.
It has been mentioned before. The smaller the radius of the circular orbit, the more energy needs to be expended during the acceleration process to constrain the orbit of the accelerated objects and allow them to run in the circular orbit.
If accelerating the spacecraft only requires a small part of the energy to correct the orbit, accelerating high-energy particles means that most of the energy is used to maintain the constraints on the circular orbit.
Otherwise, if you just accelerate a few microscopic particles to close to the speed of light, no matter how much energy is consumed, it will not cause a power outage in an entire city before the advent of controllable nuclear fusion technology. Most of the energy here is consumed in constraining high-energy particles.
On the track.
As the circular orbit becomes larger and larger, less energy needs to be consumed in the constrained orbit. In the case of a circumsolar orbit accelerator, this part of the energy can even be ignored, and the cost of high-energy particle collisions will also decrease.
To the price of cabbage.
Compared with the linear acceleration track planned and tried before, this new acceleration method is obviously more efficient and practical.
"After having the successful experience of the first construction, we can try to build more similar circular orbits one after another. The higher the orbit area, the higher the upper limit of acceleration, and the cost of the constrained orbit will be higher.
The smaller it is.
Theoretically, we can also adjust the orbit of the accelerating ring by continuously accelerating the spacecraft." Lanno gave a reverse acceleration plan on the holographic projection, that is, the spacecraft flies in the opposite direction of the accelerating ring's orbit, and every time
The reaction force provided by the secondary acceleration will increase the linear velocity of the accelerating ring, which will slowly increase the orbit of the accelerator. This also allows the orbital height to be fine-tuned by accelerating the spacecraft in reverse.
The plan was very detailed, which made everyone in the Planetary Defense Council feel a little confused. There were too many technical details in it, as if Lanno had developed a similar project and dealt with various problems in the process.
A lot of experience has been accumulated about the problem.
However, this is obviously impossible. He is just a clone. Everything from birth to now has been seen. Even his original body cannot have such a chance.
Naturally, they don’t know that Lan Nuo has gained experience in the world of Zhetian. Many planets in Zhetian world are as big as stars, or even bigger than stars. They have built satellites in their planetary orbits.
system. The technology required is basically the same as establishing a circular acceleration orbit in the solar orbit. When the Lannos first built the satellite system on Ziwei, they had already accumulated a lot of experience and successively built satellite systems for other giant living planets.
Over time, this experience has become more and more abundant. It is not easy to build the space highway in the orbit of the solar system.
