Will the out-of-control servitor meet the cosmic cat?

For cats who are still using deuterium-tritium fusion, this is still too far away-deuterium-helium triple fusion is about ten times more difficult than deuterium-tritium fusion, and deuterium-deuterium fusion is deuterium-helium triple fusion Therefore, it can be seen that after mastering helium trifusion, there will be a fairly long gap period. During this period, civilization needs a large amount of helium trifusion, but lacks the means of independent production.

Fortunately, this helium-III mining ship from the starfish civilization came.

Although it has been soaked in water for so long, it is impossible for Hong to restore it and reuse it. It is even more difficult to learn some technology from it, and since it is not a battleship after all, from the perspective of military use, the efficiency of reverse engineering is obviously not as good as Continue to toss on the bride price or 2945.

But its existence is a huge gift - there is no need to make complicated "guesses", "conceptions", and no need to imagine those fancy means. When this mining ship appears, a fact It was placed in front of her very clearly.

It is feasible and economical to use a spacecraft to enter the atmosphere of a giant planet to mine helium-[-].

Of course, its material and structure, especially the advanced layer, can withstand the huge amount of heat generated by air compression for a long time at a high speed of more than ten kilometers per second, and the heat insulation layer that can be packed in an aircraft The engineering level of the next set of high-efficiency purification, refining and diversion facilities, and the complex heat dissipation mechanism that effectively discharges heat under long-term operation are all worth our time to reverse.

At present, the most advanced aerospace plane of the Cat League, its insulation layer is just to resist the short-term heat when it breaks into the atmosphere. It only needs to persist for a few minutes, and even the hottest stage is the tens of seconds just entering the atmosphere. Once the speed slows down, its heat will soon drop exponentially, which is a few Wallaces away from the difficulty of flying in the gaseous planetary atmosphere for a long time, and the high speed of tens of kilometers per second when entering and leaving.

How does it do it?

Hong is very interested in this.

With her research, the mysterious veil of this spaceship is constantly being revealed—it is certain that, judging from the performance of the heat insulation layer in the normal state restored so far, the design scene of this spaceship should not be Gas giant planets like Dawn Core, Jupiter, and Saturn are more inclined to ice giant planets like Neptune and Uranus.

Although they are all a ball wrapped in a large mass of gas, there is a difference between a ball and a ball. The escape velocity of a gas giant planet like Jupiter can easily reach [-] to [-] kilometers per second, while an ice giant like Uranus The escape velocity of the giant planet is only [-] kilometers per second.

The difficulty suddenly dropped to another level.

According to the results restored by the red computer, this spaceship, or aerospace plane, should have a pair of relatively narrow wings. With its specially shaped hull, it can form a class with a relatively low aspect ratio. The flying wing structure provides a certain lift for its activities in the atmosphere, so as not to overwhelm the speed to maintain the altitude, and greatly reduces the heat insulation and engine load of its cruising state in the atmosphere.

However, although it seems that the number is not high, and the cruising state is "only" a few kilometers per second, in practice, it will be found that the end of the ballistic missile returns to the atmosphere at this speed. Such a high speed must be maintained for a long time. It is inconvenient to make a thick wing that is unbearable, so instead of adding weight to it, it is better to simply turn it into a disposable product, so that the aircraft can be quickly disassembled at the space station and replaced with a new pair every time it returns to space. Well - that's why Hong didn't find its wings.

It is estimated that it was attacked while changing the wings.

Hong guessed so.

Speaking of which, compared with the aerospace planes used on terrestrial planets like the Cat League, this professional mining ship sailing in gaseous planets has a unique advantage——

It can obtain continuous fuel supply from the outside world.

After all, whether it is a gas giant planet or an ice giant planet, its atmosphere contains a huge amount of hydrogen and helium. Hydrogen can be separated from deuterium to form deuterium-tritium fusion with the self-sustained tritium in the reactor, and it can also be purified from helium three Steal some helium trifusion from the crew to form deuterium-helium trifusion to provide considerable thrust and energy.

Then, the mining ship can also supply hydrogen to the ramjet engine to maintain its continuous jet voyage in the atmosphere. At the same time, it can also provide a wave of afterburner when it leaves the atmosphere to make up for the lack of acceleration of the fusion engine.

Therefore, it can be said that without considering the loss caused by long-term low-temperature (relative) voyage of its heat insulation layer, this mining ship can maintain a nearly semi-permanent voyage in the atmosphere, and the duration only depends on equipment loss.

This is something that the atmospheres of terrestrial planets cannot do, because there is basically no hydrogen in the atmospheres of their habitable planets, this thing is too light, and the planets they are suitable for cannot stay. Only liquid hydrogen needs to be carried, and the feature that the oxidant can be replenished from the air produces much higher performance than rockets.

However, at present, she still doesn't know why this 70-ton super-large aircraft appeared here. From Hong's actual survey, this thing is not equipped with a warp engine, nor does it give a possible external warp engine. The high-speed engine leaves pipelines and slots, and in addition, it has no need to carry out interstellar routes alone. Obviously, this thing itself should not have the ability to travel faster than the speed of light.

As far as the currently known methods are concerned, this thing was either rolled over by a wormhole, or brought over by other superluminal spaceships or facilities—disregarding the fact that the wormhole disappeared after it opened, the former can be ignored, so the possibility mainly falls on the latter.

As early as when it was first discovered, Hong had already sent some small scientific research ships and exploration satellites to other planets in this galaxy to see if there were other crashed spaceships, broken star gates and the like.

As of now, no trace has been found.

This spaceship seems to have suddenly appeared above the planet without warning on a windless night, and then slapped into the water with a snap - all passages are kept sealed, and the mechanical devices are almost in place. Judging from normal navigation conditions, these starfish probably died before they fell into the sea.

Otherwise, with such a strength that the spacecraft can maintain its structural integrity without obvious damage even after falling into the sea, and even maintain the low-load state of the reactor for about several years under the control of the automatic program after falling into the sea, it is impossible to have a large number of ships. The ship structure and the starfish buffered by the water body were directly shot to death at the moment of falling into the sea.

However, Hong can only make reasonable speculations. Judging from the various details discovered in the later survey, this spaceship has been lying on this seabed for at least 5000 years, and many evidences that might have been found have long been With time, it disappeared, and the data in the shipboard computer could not be read out for a long time.

No way, such a mining ship, who would waste time and effort installing a bunch of mechanical hard disks or optical discs, all of which are electronic storage media similar to flash memory, let alone Hong doesn’t know how to analyze it, even if he knows, after thousands of years, I can't find anything I lost long ago.

Therefore, unless we can find the person/equipment who experienced the accident and survived to this day, or the technology is advanced in the future, flying thousands of light-years away, locking the time and place and looking here with a telescope, otherwise The answers will all be buried in the long river of time.

never again.

PS: Let me report the current situation of Maomao. The old computer was repaired three days later and the keyboard was sent. It is estimated that the motherboard has a hidden damage and is currently unusable. I plan to take it back tomorrow or the day after tomorrow and let it be repaired. The motherboard is burnt like that. Repair it Most of them won't live for long, and it's better not to be pulled down if they can do it.

The new computer couldn’t be opened due to a problem with the screws on the back cover, so I applied for a replacement, but the customer service said that it would take 7-15 days for the replacement to be guaranteed (because I had to confirm whether the damage was caused by my disassembly)

If you don’t remove the back cover, you can’t find this quality control problem. If you find it, it means that you plan to remove the back cover, then I will tell you that the damage caused by dismantling the machine by yourself is not guaranteed-it is a three-dimensional defense.

All the new and old computers can’t be used. The cat’s mother took away his office notebook on a business trip. The only thing left to me is my mobile phone. Efficiency is greatly affected. A chapter takes seven or eight hours, and the computer may not be able to handle it in a short period of time, so Maomao may not be able to guarantee daily updates these days.

Don't worry about full attendance, it was gone when there was no update yesterday.
