Vol 22 Chapter 485: come down

When the thruster was cut off, there was a slight accident. This accident was that we found that there was actually a linkage device on the thruster. As long as the thruster was cut off, the power compartment where the thruster was located was automatically closed, and then After a few minutes, he also cut off the hull automatically.
This setting has no problem with the original use of the spacecraft, because the final cutting-off method of the power chamber should normally be controlled by the central computer. We thought that after forcibly seizing this power chamber, the connection line was cut, so only Can be controlled manually. If according to the designer's idea, since it is controlled by the computer, then the personnel inside should be evacuated in advance before cutting off the propeller, and then the extra power compartment is automatically discarded after discarding the propeller, and the propeller is gone anyway. It is also a burden to have a power cabin. Therefore, this design has no problem with the original use.
However, we set it manually, which caused us to leave the power cabin within one minute once we confirmed that we were cutting off the thruster. But when the thruster is cut off, the power compartment will be closed, which means that there is no time for us to leave the power compartment.
This setting is quite annoying, but we have to find a way to solve this problem.
I do n’t know if it ’s anxious, but we found this linkage at the moment when the first thruster was cut off, but because the entire power compartment will be cut off in one minute, the thinking time is almost zero. It was at this critical moment that Xiao Chun, who was in charge of this cabin, suddenly thought of a solution.
In fact, Xiaochun's solution is quite exaggerated. Normal people can never do it. However, none of us are normal people, so we can do things that normal people cannot do.
After that thruster was cut off, there was a sudden, continuous explosion at the root of the fixture below the thruster. This is a preset explosion point designed to cut off the thruster. After these explosion points explode, all the connections between the thruster and the spacecraft are cut off. After the explosion, a series of dense blasts also occurred in the thermal insulation layer and protective armor at the bottom of the power cabin, which directly blasted a large piece of shell outside. Due to the high-speed airflow, the blasted shell disappeared instantly, and the position of the thruster at the rear of the spacecraft became a large hole.
Because the power cabin itself is air-pressured, and the outside is a high-altitude low-pressure environment, when the shell exploded, the propeller, which had been separated from the hull, was immediately lifted out. Xiaochun jumped off the thruster when the thruster automatically blasted the connection device, but she quickly found the linkage device, and then she didn't think about it. She immediately reminded Jingjing at the door and rushed back to the thruster. On the propeller, then after the propeller flew out of the hull, she slammed the propeller underneath with Jingjing and the Hydra soldier who came to reinforce it, and jumped back with the help of reverse thrust.
They certainly did not want to jump back to the power module, but jumped to the main structure in front of the spacecraft and hung themselves on it.
At this time, although the speed of the spacecraft has dropped significantly, the speed is still as high as twenty-three times the speed of sound. The wind pressure outside is astonishing. If it were not wearing power armor, normal people would be torn to pieces by this strong airflow. Of course, our people can do this even without wearing power armor, but it will be a little uncomfortable.
When Xiaochun jumped onto the main body shell of the spacecraft, they arrived a minute later, and then the power capsule actively cut off.
In fact, the power capsule at this time has only a shell and some bits and pieces, but cutting out this thing can really reduce the weight of the hull, because this part consists of a large number of support beams and load-bearing structures, even a shell is quite heavy of.
After the spacecraft dropped this burden, the control became significantly more flexible, while Xiaochun and Jingjing and the Hydra soldier climbed down the shell and climbed back to the gap left after the power compartment was cut off. This part seems to be specially prepared for cutting off the power cabin, and there are actually heat insulation layers and fairings. However, because this place was previously connected to the power cabin, there are several entrances here. Xiaochun, they randomly found the nearest one, and forcibly destroyed the gate and returned to the ship.
With this example, we basically used this method to safely return to the spacecraft afterwards without any accidents.
After throwing away the two propellers at a stretch, we also threw down the damaged propellers together, and on the sea below, the long-awaited recovery team quickly rushed to the airdrop to rescue the fallen propellers. The device is gone, but if it is intact or fragmented when it is picked up, it is only a matter of luck.
It took almost ten minutes to cut off all the propellers. The ship was all short, but it didn't drop directly at this time, because although the super-thruster of the alien was thrown by us, However, there were more than a dozen super electromagnetic engines at the bow and the middle of the hull, so the spacecraft did not fall directly.
The characteristic of the super electromagnetic engine is that it can directly use electric energy to convert it into propulsive kinetic energy, and the energy consumption is not high, but its disadvantage is that the limit output is low, and it cannot support the spacecraft from the gravitational circle. Because of the working principle of the super electromagnetic engine, it can theoretically accelerate the spacecraft to the speed of light all the time. At this point, the rocket engine produced by humans cannot be done, because the rocket engine is propelled by generating reaction forces, that is, if the speed of the spacecraft and the speed of the high-speed particles are equal, the power of the thruster will be completely It is equal to zero, and in fact, as the speed increases, the power of the rocket thruster will continue to decrease. Therefore, even if there is an infinite fuel rocket engine, it will not actually reach the limit speed at the moment of fuel explosion because of the propulsion. The relationship between force and speed is a function curve that approaches infinity but never reaches. The faster the speed, the lower the power.
But the super electromagnetic engine is different. Its propulsive force will not decrease with the increase of speed. 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, theoretically as long as the energy is sufficient, This thing can be said that the spacecraft has been accelerating to the speed of light.
However, there is a problem on Earth. Because of the air resistance, the faster the speed, the greater the resistance, but the characteristic of the super electromagnetic engine is that the output is very low. If it is in space, there is no air resistance, and the space is wide enough, so it can slowly accelerate and sooner or later it can reach very high speeds. That's why we need a super-electromagnetic engine as one of the power systems for migrant ships. Because this super-electromagnetic engine can reach very high speeds in the universe, but the acceleration time may take many years.
However, due to air resistance on earth, this acceleration will be limited, and even the tiny output of the super-electromagnetic engine will cause it to not only resist air resistance, but not even the weight of the hull. Therefore, the spacecraft needs a power to get it into space before it can be accelerated by a super electromagnetic engine.
However, the alien thrusters on this spacecraft have been thrown out, and the rest are only super electromagnetic engines and some small rocket engines for emergency steering and forced landing. In this case, the power of the spacecraft is lower than Due to its own weight, the spacecraft was falling towards the ground after all the alien thrusters in the city.
Of course, although the ship has lost most of its power, because we also don't want it to fall directly into a pile of debris, we have completed the attitude control and deceleration for this ship before throwing away the alien thrusters. Therefore, at present, the spacecraft is still barely supporting the forward movement under the action of the super electromagnetic engine, but it can't fly far according to the current speed estimation.
"Nuwa, calculate our trajectory." After regrouping, the first thing I did was not to ask about the engines, but to ask me to help us figure out the current state of the spacecraft.
The son-in-law is famous for his multi-purpose, so while taking care of the salvage team at sea, he is still helping us calculate the flight trajectory. I asked our son-in-law here and gave us our flight trajectory.
"Are we already over Japan?" Aimenis asked first, seeing the map and the speculative route of the flight path.
Hans suddenly said: "Did we follow this trajectory, are we going to fall into Tokyo Bay? Have you notified Japan to evacuate?"
The son-in-law's voice replied very quickly: "When you first entered China ’s airspace, I informed the joint summit of the world and the Japanese government to pay attention to the disaster warning. When you flew out of the Chinese waters, I gave them the latest Prediction of the landing point, most of the Tokyo city is busy evacuating, and there should be no one at sea. "
"That's okay." Hans is a soldier, not a murderer, and he is a German. Discipline and honor are more important than life. Of course, we will not allow a large number of poor people to be killed or injured because of our mistakes.
In fact, according to the current forecast, we should not have much impact on Japan this time. Of course, the impact is definitely there. According to our calculations, the final crash site of the spacecraft was Tokyo Bay, and the final speed before the crash was about three times the speed of sound.
The current hull is about the size of six aircraft carriers. Such a large thing hits the sea surface with three times the speed of sound, and the huge waves set off can be imagined. But fortunately, we fly from west to east, and the east side of Tokyo Bay is basically a low-development area. The downtown area of ​​Tokyo is located in the northwest direction of Tokyo Bay. The huge waves we set off after falling into Tokyo Bay will Moving east, all Tokyo needs to worry about is the aftermath of the recoil, and if something explodes on the spacecraft, this is also a troublesome matter. Others are not much of a problem. Even if there were real casualties, it should not be too exaggerated.
To be honest, if we and some of the domestic anger are slowed down, the other party may wish that the spacecraft fell in the very center of Tokyo. However, we never have this idea. First, we are dragons, not murderers, and it is not our hobby to kill civilians. Second, although we are wearing power armor, if the spacecraft hits the ground at three or four times the speed of sound, the impact is not something we can resist. 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.
Do n’t forget, the Japanese summit also includes representatives from the Japanese side, which means that if we deliberately pitted Japan on our side, the leader ’s side would immediately turn over with us. .
Although our country almost went to war with Japan before, and even saw the top-level war mobilization rehearsal program in my capacity, but at the end, the high-level vetoed this decision. Because of the advance of the solar system killer, everyone has no energy to fight again. .
After all, wait until the new colony, and everyone will come back again. Now, at this time, if you do n’t do well, you will get rid of it, and then all humans will die together. At this time, no leader dares to create a problem at this time. This is why the relations between countries seem to have suddenly improved recently, because everyone knows that they will not let go of those countries at this time. The contradiction between them, the next moment waiting for everyone is human extinction.
In fact, after hearing that the site of the fall was in Tokyo Bay, leaders of various countries were relieved at the joint meeting over the United States. If the wreckage of the spaceship smashed into the city of Tokyo at this festival, the fun would be great.
"Everyone's attention, we are now in Japanese airspace." We are planning a mission while occupying a separation capsule, and the enemies outside seem to ignore us, and no one has attacked for a long time, as if on this spacecraft. Just us. Of course, I know that they are actually still ~ EbookFREE.me ~ I just don't know what they are busy with, they just have no time to care about us.
Taking advantage of the rare free time, I told Hans and Ling about their arrangements for a while.
"The spacecraft landing point should be some east of Tokyo Bay, but we will not fall with the spacecraft."
Hans asked, "Did you just jump out halfway? Our power armor can fly anyway. At two or three times the speed of sound, we can still control the flying attitude to achieve a controlled landing."
"I know everyone's power armor is very good, but we can't do it now." I said, "Hans, don't say it first, listen to me. Our mission is not to keep our own lives, in fact, it depends on With our current equipment, it is difficult to die. However, the enemy may survive many people after the spacecraft crashes. Those guys have worked hard to survive for themselves. The life support system on this spacecraft is so advanced that you cannot imagine, so land Opportunities for the other party to survive afterwards are great. And there will definitely be many people left. "
"What shall we do then?" Hans asked.
"We just fell with the ship, but separated at the last second," I said. R1152
