Chapter 485 Fall

There was a slight surprise when the thruster was cut off. The surprise was that we discovered that there is a linkage device on the thruster. As long as the thruster is cut off, the power cabin where the thruster is located will automatically close, and then Minutes later, it also automatically cut away from the hull.

There is no problem with this setting for the original use of the spacecraft, because the final separation method of the power room should normally be controlled by the central computer. We thought that we cut off the connection line after forcibly seizing the power room, so we only Can be controlled manually. If according to the designer's idea, since it is computer-controlled, then the personnel inside should be evacuated in advance before cutting off the thruster, and then discard the thruster and then automatically discard the excess power cabin. Anyway, the thruster is gone. , having a power cabin is also a burden. Therefore, this design has no problem with the original use.

However, we set it manually, which means that once we confirm to cut off the thruster, we must leave the power cabin within one minute. However, when the propeller is cut off, the power cabin will be closed, which means there is no time for us to leave the power cabin.

This setting is quite annoying, but we have to find a way to solve this problem.

I don’t know if it was a matter of desperation, but we discovered this linkage device at the moment when the first thruster cut off, but because the entire power cabin would be cut off in one minute, we had almost zero time to think. It was at this critical moment that Xiaochun, who was in charge of this cabin, suddenly thought of a way.

In fact, Xiaochun's solution is quite exaggerated, and it is absolutely impossible for normal people to do it. However, none of us here are normal people, so we can do things that normal people cannot do.

After the propeller was severed, a series of explosions suddenly occurred at the root of the fixture below the propeller. These are preset explosion points designed to cut off the thrusters. After these explosion points explode, all connections between the thrusters and the spacecraft will be severed. after the explosion. The heat insulation layer and protective armor at the bottom of the power cabin also experienced a series of intensive explosions, directly blowing away a large piece of the outer shell. Due to the high-speed airflow, the blasted shell disappeared instantly, and the location of the propeller at the tail of the spacecraft turned into a big hole.

Because the power cabin itself has air pressure, and the outside is a high-altitude low-pressure environment, when the outer shell explodes. The propeller that had separated from the hull was immediately lifted out. Xiaochun had already jumped off the thruster when the thruster automatically exploded the connection device, but she quickly discovered the linkage device, and without thinking, she directly reminded Jingjing at the door and rushed back to the thruster. Then after the propeller flew out of the hull, she, Jingjing and the Hydra soldier who came for reinforcements kicked the propeller under her body hard, and jumped back with the help of reverse thrust.

Of course they were not jumping back into the power cabin, but onto the main structure in front of the spacecraft. And hung himself on it.

Although the speed of the spacecraft had dropped significantly at this time, it was still as high as twenty-three times the speed of sound. The wind pressure outside was astonishingly high. If not for wearing power armor, a normal person would be torn to pieces by this strong airflow in an instant. certainly. Our people can do this without wearing power armor, but it will be a little uncomfortable.

When Xiaochun and the others jumped onto the main shell of the spacecraft, one minute soon came, and then the power cabin took the initiative to cut away.

In fact, the power cabin at this time only has a shell and some bits and pieces left. However, cutting this thing off can indeed reduce the weight of the hull a lot, because this part consists of a large number of support beams and load-bearing structures. Even the shell is quite heavy.

After the spacecraft got rid of this burden, the control became obviously much more flexible, and Xiaochun, Jingjing and the Hydra soldier climbed back along the outer shell to the gap left after the power cabin was cut away. This part seems to have been specially prepared for cutting off the power cabin, and it actually has a heat insulation layer and a fairing. However, because this place was previously connected to the power cabin, there are still several entrances here. Xiaochun and the others randomly found the nearest one. And he forcibly destroyed the door and returned to the ship.

With this example, we basically used this method to return to the spacecraft safely without any accidents.

After throwing away the two propellers in one go, we also threw the damaged propeller down together. On the sea below, the recovery team that had been waiting for a long time rushed to the airdrop position to rescue the fallen propeller. The vessel is gone, but whether it comes out intact or in pieces depends on luck.

It took almost ten minutes to cut off all the thrusters. The spacecraft was completely shorter, but it did not fall directly at this time, because although the aliens' super thrusters were thrown down by us, However, there were still more than a dozen super electromagnetic engines working at the bow and middle section of the hull, so the spacecraft did not fall directly.

The characteristic of the super electromagnetic engine is that it can directly use electrical energy to convert into propulsive kinetic energy, and the energy consumption is not high. However, its disadvantage is that its limit output is low and it cannot support the spacecraft to escape the gravitational circle. Because of the working principle of the super electromagnetic engine, it can theoretically accelerate the spacecraft to the speed of light. This cannot be done by rocket engines produced by humans, because the rocket engine relies on the reaction force generated by the jet for propulsion. That is to say, if the speed of the spacecraft is equal to the speed of the ejected high-speed particles, the power of the jet thruster will will be completely equal to zero, and in fact, as the speed increases, the power of the rocket thruster will continue to shrink. Therefore, even if there is an unlimited fuel rocket engine, it will not actually reach the ultimate speed at the moment of the fuel explosion. , because the relationship between propulsion force and speed is a function curve that approaches infinitely but never reaches it. The faster the speed, the smaller the power.

But the super electromagnetic engine is different. Its propulsion force will not decrease as the speed increases. That is to say, in addition to its own power loss, it can completely convert its output power into the kinetic energy of the spacecraft. Therefore, in theory, as long as the energy is sufficient , this thing can accelerate the spacecraft to the speed of light.

There's a problem on Earth, though. Because of the existence of air resistance, the faster the speed, the greater the resistance, but the characteristic of the super electromagnetic engine is that its output is very low. If you are in space, there is no air resistance. And the space is wide enough, so it can slowly accelerate and sooner or later reach very high speeds. This is why we need a super electromagnetic engine as one of the power systems of the immigrant ship. Because this super electromagnetic engine can reach very high speeds in the universe, but the acceleration time may be as long as several years.

However, due to air resistance on Earth, this acceleration will be limited, and even the tiny output of the super electromagnetic engine itself makes it unable to resist air resistance. Even the ship's own weight cannot be fully borne. Therefore, the spacecraft needs a power source to propel it into space, and then it can be accelerated using a super electromagnetic engine.

However, now that the alien thrusters on this spacecraft have been thrown out, the only ones left are the super electromagnetic engine and some small rocket engines for emergency steering and emergency landing. In this case, the power of the spacecraft has been lower than Its own weight, therefore. After all the alien thrusters in the city, the spacecraft is falling towards the ground.

Of course, although the ship has lost most of its power, because we don't want it to fall into a pile of pieces, we have completed the attitude control and deceleration work for the ship before throwing away the alien thruster. . So at present, the spacecraft is still barely supported by the super electromagnetic engine to jump forward, but it is estimated that it cannot fly very far at the current speed.

"Nu Wa, calculate our trajectory." After regrouping, the first thing I did was not to ask about the status of those engines, but to ask Nu Wa to help us figure out the current status of the spacecraft.

Nuwa is famous for multi-tasking. So while taking care of the salvage team at sea, he was also helping us calculate the flight trajectory. I just asked Nuwa and she gave us our flight path.

"Are we already over Japan?" Seeing the map and the presumed route of the flight path. Amynis was the first to ask.

Hans suddenly said: "According to this trajectory, it is estimated that we will fall into Tokyo Bay? Have you notified Japan to evacuate immediately?"

Nuwa's voice replied very quickly: "When you first entered China's airspace, I notified the World Summit to notify the Japanese government to pay attention to the disaster warning. Just now when you flew out of China's waters, I had already given them the latest According to the prediction of the landing point, most of Tokyo is busy evacuating now, and there should be no people at sea."

"That's okay." Hans is a soldier. He is not a murderer, and he is a German who values ​​discipline and honor more than life. Of course, he will not allow a large number of poor people to be killed or injured due to our mistakes.

In fact, based on the current forecast, we should not have much impact on Japan this time. Of course, there must be an impact. According to our calculations, the final crash location of the spacecraft was Tokyo Bay, and its final speed before crashing was about three times the speed of sound.

The current hull is about the size of six aircraft carriers. One can imagine the huge waves caused by such a big thing hitting the sea at three times the speed of sound. But luckily, we were flying from west to east, and the east side of Tokyo Bay is basically a low-development area. The urban area of ​​Tokyo is located in the northwest of Tokyo Bay. The huge waves set off after we fall into Tokyo Bay will be Pushing eastward, what Tokyo needs to worry about is the aftermath of the recoil, and if something on the spacecraft explodes, this will also be troublesome. Others are not much of a problem. Even if there are real casualties, it should not be too exaggerated.

To be honest, if we and some angry young people in China were relieved, the other party might wish that the spaceship fell in the center of Tokyo. However, we will never have this idea. First, we are dragons, not murderers, and killing civilians is not our hobby. Second, although we are wearing power armor, if the spacecraft hits the ground at three or four times the speed of sound, we cannot resist the impact. Therefore, falling into the sea is actually a means of self-protection. Finally, and most importantly, it is for the safety of people around the world.

Don’t forget, the world summit joint meeting in the United States now also includes representatives from Japan. In other words, if we deliberately cheat Japan, their leaders will immediately fall out with us. .

Although our country almost went to war with Japan before, and I even saw the top-level war mobilization rehearsal plan, but in the end the top management vetoed this decision. Because of the advance of Solar System Killer, everyone no longer has the energy to fight another war. .

Let's wait until we get to the new colony and start over again. At times like this, we might get out of control, and then all of humanity will be finished together. At this time, no leader dares to cause trouble at this time. This is why the relations between countries seem to have suddenly improved recently, because everyone knows that if they do not let go of those countries at this time, The contradiction between them, the next moment waiting for everyone is the extinction of human beings.

In fact, after hearing that the crash site was in Tokyo Bay, leaders of various countries also breathed a sigh of relief at the joint meeting in the United States. If the wreckage of the spaceship hits Tokyo at this juncture, it will be a lot of fun.

"Attention everyone, we have now entered Japanese airspace." We have occupied a separate cabin and are arranging tasks, and the enemies outside seem to not care about us. No one has come to attack for a long time, as if on this spacecraft Just us. Of course, I know that they are actually still there, but they just don’t know what they are busy with and have no time to care about us.

Taking advantage of the rare free time, I told Hans and Ling about the arrangements for a while.

"The landing point of the spacecraft should be somewhere east of Tokyo Bay, but we will not fall with the spacecraft."

Hans asked: "Should we just jump out halfway? Our power armor can fly anyway. At two or three times the speed of sound, we can still control the flight attitude to achieve a controllable landing."

"I know everyone's power armor is awesome, but we can't do that now." I said, "Hans, don't say anything yet, just listen to me. Our mission is not to save our own lives. In fact, we just rely on With our current equipment, it is difficult to die. However, many enemies may survive after the spacecraft crashes. Those guys have worked very hard to survive. The life support system on this spacecraft is so advanced that you can hardly imagine it, so the landing The other party has a high chance of surviving after that. And there will definitely be a lot of people left."

"What are we going to do?" Hans asked.

"We fell with the spacecraft, but separated at the last second," I said. (To be continued ~^~)
