Super Shenhao Technology System
Page 1556
The propulsion system of "Mars Express" is very special, compared with the conventional ion engine drive, which ejects argon atoms backward at super high speed to obtain thrust.
The propulsion system of the "Mars Express" is a bit of an opposite taste. Its propulsion engine is not only a rear conventional fuel propeller, but a front engine. It uses thousands of lasers to irradiate hundreds of thousands of lasers and uses light sails to propel it. Mars Express and its "Firefly".
Although a thousand groups of lasers will generate a reverse thrust when activated, the kinetic energy of the thrust compared to the light sail is completely acceptable, and only a small part of the thrust is needed to offset the reverse thrust.
Chapter 180 Seven Untitled
The acceleration of the light sail pushing the entire object is indeed very fast, but it does not appear to be too shocking. On the one hand, it is due to energy issues, and on the other hand, it is also due to the fact that there are astronauts on the spacecraft.
Even so, during the long voyage stage, more than ten times of acceleration, the continuous acceleration of batches for the entire spacecraft along the way, can also bring quite fast acceleration to the spacecraft after a long period of accumulation.
Theoretically, under the ideal state of sufficient material strength and energy output, continuous acceleration can bring the entire spacecraft infinitely close to the speed of light.
Infinitely approaching the speed of light only needs three or four months of continuous acceleration. Of course, this is an ideal state.
But these problems are not the key to the design of "Mars Express" as a front engine. The most critical factor is the size of the entire aircraft. Mars Express, Yinghuo, and their outpost bases to be established on the surface of Mars and a surface crystal cutting laboratory.
Coupled with two landing vehicles and other miscellaneous materials, the total volume of the entire aircraft is quite amazing.
The "Firefly", which is orbiting Mars alone, has a mass of nearly 1500 tons. Adding other parts, the entire aircraft is almost 4000 tons in volume, which is equivalent to half of the Tiangong orbiting star port.
The actual situation of such a huge body can only use the front engine to safely shuttle this big guy between the stars.
Just imagine if it is a conventional propulsion system, such as an aircraft with a rear engine like a rocket, its hull structure and material properties must be strong enough to handle the thrust of the engine.
In other words, the structure of the entire aircraft must be built like a skyscraper with a solid middle part and bottom part, so as to ensure that such a huge spaceship will not collapse and fall apart in the face of strong thrust.
This is also the reason why the outline of the rocket is like a spire, with a small upper end and a huge middle lower layer. For example, the American "Saturn 5" and the current American "Noah" are designed in this way.
But the front engine is quite different. The hull does not need to be designed to be as thick and strong as a super-heavy rocket or a building. The biggest requirement is to be as durable as a rope.
This is also the biggest reason why the total length of Mars Express and its Yinghuo once exceeded 1000 meters, and the structure appeared so slender.
The design of the front engine can greatly reduce the weight of the hull structure, making it possible for a super-large spacecraft to travel across long-distance interstellar travel. Going to the asteroid belt for mining operations and transportation is not an unreachable fantasy.
There is no doubt that this is of great significance for interstellar navigation, otherwise why is the American "Noah" so "small"?
Why is it in the shape of a tower top?Moreover, due to the carrying capacity, the Americans' "Mars Project" will be divided into three times.
And a one-way journey takes nearly half a year, and a round trip between the Earth and Mars plus mission time will take almost a year.
We still have to wait for the golden voyage stage of relative distance. Under the current rapid technological change, time is so precious.It's not that Americans don't have the means.
Just the few giant companies participating in the "Mars mission" are not without money, and the United States is not without money.
The real reason is that the field of laser technology is not as good as that of China, and the field of light sail technology and solar panels is also far ahead of China.
Just the vast ocean of solar panels in the Qinghai area is enough to illustrate some problems.
Not to mention the most critical issue of energy supply, for Americans who do not have amethyst, this is a real knot that cannot be solved, not to mention the problem of mature laser technology.
It is to obtain enough thrust that requires more fuel to supply the energy output of the laser column, and carrying more fuel means that the volume of the spacecraft will increase, which in turn requires stronger thrust.
Obviously, this is an endless loop, but Ziyuanjing helped Huaxia Future untie the biggest infinite loop, that is, reducing the size of the spacecraft without dropping the energy supply.
At this moment, in the space of "Firefly".
Li Linfei was sitting on his desk in the centrifuge cabin, staring at the dizzying data on the screen without saying a word.
This time, it cost a lot of money to go to Mars not far away hundreds of millions of kilometers, the purpose is to get the amethyst crystal on it.
But obviously, it is not a simple matter to obtain these fatally attractive crystal ores on Mars. What Li Linfei worries and cares most is how to get a small piece of purple stone from such a large piece of purple stone. cut it down.
Moreover, according to the current understanding of the characteristics of Amethyst Crystal, it is a bit unrealistic to estimate that it is a bit unrealistic to collect scattered crystal fragments at the falling point first.
Even a nuclear bomb bombardment cannot break down this kind of stone. This time, the huge "Terminator" crashed into the surface of Mars.
Maybe not even a shard of it would come off, which would mean manually cutting it piece by piece from the big guy.
Li Linfei did invent the technology of cutting Amethyst, that is, the "condensation cutting method", but that is because of the favorable external environment on the earth and the advantages of cutting the size of the object, but in the face of a "terminator" that is calculated in kilometers ", it is really anxious to scratch the head.
Here is Mars, not the earth, and the environment is harsh. It is relatively difficult to create an ultra-low temperature environment with infinitely close to absolute zero. The unavoidable harsh actual environment requirements require a mobile low-temperature laboratory to meet.
Fortunately for him, he currently has a large amount of amethyst crystals full of energy, and a series of activities to be carried out on Mars will require massive amounts of energy as support.
Whether it is an inspection base, a mobile cutting laboratory, especially a mobile laboratory that manufactures an ultra-low temperature environment, it is driven by a large consumer of energy. Fortunately, amethyst with high energy storage can support a series of huge equipment. Energy consumption.
"Old... Uh no, Professor Lin, there was a message from the Earth Command Center seven minutes ago." At this moment, Xiao Rui, who played the role of his assistant, came to him.
"What news?" Li Linfei asked curiously.
"The American Noah has just entered the high-altitude orbit of Mars and sent the news back to Earth. NASA then announced the news and its follow-up actions, according to the briefing from the headquarters."
Shockery looked at the time while talking, and added: "According to the time on board, the Americans will be 53 hours later, and the crew of Noah, Scovo and Jackson, will take the 'Orion' spacecraft for the first manned landing on Mars. "
As he said that, Xiao Rui sighed, "If there are no accidents, the first human to land on Mars will be an American. I'm still a bit unwilling. The No. 1 landing on the moon was snatched by the Americans."
"Mars No.1 was also snatched by them, which is really uncomfortable. Our current level of space technology is obviously stronger than that of the Americans."
Chapter 180 is just a false name
"It's just a false name, what's the point of being uncomfortable?" Li Linfei smiled, seemingly indifferent.
But Xiao Rui didn't think so: "Although that's the case, this is an achievement that will definitely be recorded in the annals of human history after all. It has a huge influence. Armstrong's footprints, the words of one small step for mankind, one giant leap for mankind, are all in the world. It has been widely circulated among all human beings, and this time I don’t know how Lao Mei will show it off.”
But Li Linfei said: "What is real influence? Real influence needs real strength as a support. We are pragmatic. We are here to seek truth, not fame. You have to figure this out, Ari. .”
"Besides, the title of Mars No.1 was taken off by the Americans, but there are more first titles waiting for us, Jupiter, Saturn and their satellites."
"As long as the strength is there, the gold content of these first titles will only be higher than that of Mars, but the most important thing is that we traveled long distances, risking danger and suffering dozens of times of acceleration and deceleration. We didn't come here to get a false name, understand ."
"It would be great if the old beautiful Orion had something wrong and fell." Xiao Rui muttered.
When Li Linfei heard this, his original pleasant smile turned into a serious expression, he stared at Xiao Rui and warned with a solemn tone: "A Rui, I don't like your idea, it's very bad, put aside national boundaries and stand at the height of the entire civilization , any interstellar pioneer is great, no matter which country he is not only representing his country but also human beings."
"Even if you don't say that you are so tall, you can't curse others behind your back with such a narrow mind. He can cause problems. We can ignore and refuse even when we have the ability to lend a helping hand. This is our right, and No need to blame yourself."
"But in the same way, we have no right to interfere with others. What others do is their business. We must abide by the principles we should have."
Li Linfei's tone was not very serious, but Xiao Rui still felt embarrassed, scratched his head and didn't know how to respond.
At this moment, the public frequency announcer on the ship sounded: "Attention all units and all crew members, the last 45 minutes countdown, the spacecraft will undergo the last acceleration, all crew members please stop all related activities immediately..."
Li Linfei glanced at the announcer, and suddenly said with a sad face: "Oh, it's time to torture people again, let's go, what are you doing in a daze, hurry up and get the nest ready for a long sleep, you want to let the acceleration Paste you on the wall?"
After speaking, Li Linfei got up and walked away. Every time the spaceship was about to accelerate, the whole spaceship was full of complaints, and the spaceship was about to accelerate for the last time.
It stands to reason that everyone should cheer, at least this is the last time to be tortured by acceleration, and it is true.
