The 76th special combat team led by Shangguan Boyun is targeting a galaxy called "Kepler" and a planet 140 light-years away from the solar system, and even this star system is named Kepler's galaxy; This is the name of the civilization of Earth, and in the case of the Bosela civilization of Sirius, the planet is called "Crasso". Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Kepler is the name of a scientist in the Earth civilization, and Crassel is also the name of a scientist in the Bosela civilization. This is a "strange" planet, not a planetary strangeness, but a political strangeness - here, the Earth civilization and the Bosera civilization are divided into two halves as if they were cutting a watermelon.

It is also here that the civilization of the earth and the civilization of Bosela are actually trying to communicate - it is optimistic that it is "communication", not "reconciliation"; The scope of so-called communication is larger, and peace and violence, cooperation and confrontation, war and love are constantly staged here.

It should be said that this is a window for communication between the earth civilization and the Bosera civilization, and it is also the only window of peace between the two civilizations for the time being. It should be said that the military's arrangement of Qin Fei and others to go to this planet is also far-reaching. It's easy to get out, but where to go is an important question.

After learning this information, Qin Fei was also very excited, but he could see the journey of up to 400 days, and he was gone!

Today's Earth civilization's Starry Sky Gate technology has been able to extend the travel space by more than 200 times. But the spaceship still has to fly over little by little.

The distance of 140 light years is 200 times closer, and there is still 0. 7 light-years channel distance.

B-tier ships can reach 0 at the earliest. 9 times the speed of light - this is theoretical data, which means that the spacecraft can accelerate all the time; But in fact it accelerates to 0. It would take at least a year to speed up to 8 times the speed of light. Theoretically, anything can accelerate to sub-light speeds - as long as there is enough energy.

In a word, even if the fleet accelerates from now on, it will not reach the theoretical value when it reaches the target - and the problem of deceleration must be considered.

In interstellar, basically as much time and distance as it takes to accelerate, it takes as much time and distance as it takes to slow down! Of course, in this process, it is another thing to use the planets to accelerate and slow down. Technology has changed the world beyond recognition, at least that's what some people say.

said that Qin Fei learned about this. Immediately after loading all the "cargo", the ship took off. The whole process is very simple, there is no farewell or anything like that, an order. 25 spacecraft began to accelerate, flying from orbit near Earth to lunar orbit.

The starry sky gate to the Kepler system is not on the Moon, but on Mars. It's just that the distance from the Earth to Mars is not short, and at this time, Mars and the Earth are just separated by the sun, so it will take more than two months to fly there by spaceship. Time waits for no one. So the fleet is preparing to fly from the moon's starry gate to Mars, and from Mars to the Kepler system.

On the far side of the moon, there are more than 60 starry gates of all sizes, the smallest of which is about three kilometers, which is used in the interior of the solar system; The largest is more than 20 kilometers away and can be connected to about 50 light-years -- the starry sky gate on the moon is connected to all galaxies and planets that are completely controlled by the earth's civilization and have been fully managed.

The spaceship began to accelerate, and the acceleration of the spacecraft at this time was as high as standard Earth gravity, which was just enough to meet the needs of everyone's life.

In the acceleration of the spaceship, Qin Fei and the others were learning; It was the captain of the brigade, Shangguan Boyun, who personally taught it - in fact, it was not this guy's business. One silver warrior was enough, but Shangguan Boyun was idle and had nothing to do, so he kicked the silver warrior away. It's boring in space, and it's good to have something to do.

"In space, mechs and spaceships complement each other. Ships are large, powerful, and powerful. Accelerated flight for a long time, theoretically it can reach 0. 9 times the speed of light. But the ship is bulky, and the faster it is, the more cumbersome it becomes. When the ship's velocity is increased to 0. Above 7 times the speed of light, the mass increases geometrically.

In fact, when the ship's velocity reaches 0. At 6 times the speed of light, the mass has already tripled; to 0. 7 times the speed of light, counting its own mass. Almost 3 of the original mass. 8 times! When the ship's velocity reaches 0. At 8 times the speed of light, the mass will increase to 7. 7 times. And when the speed reaches 0. At 85 times the speed of light, the spacecraft needs to accelerate for more than 3 years, and the mass will reach about 13 times. In this case. The spaceship wants to make a corner, dodge, etc., and it is bulky beyond imagination.

Considering the actual situation, the speed of the spacecraft in space is generally limited to 0 within the interstellar space. At 1 times the speed of light, interstellar space will accelerate to 0. 6 times the speed of light, generally no more than 0. 75 times the speed of light. If the distance is farther away, it is necessary to establish a starry sky gate communication. ”

"This is the way of starry sky travel of our Earth civilization. And what about extraterrestrial civilizations? "Qin Fei is definitely a good boy. When others listened to it with relish, Qin Fei immediately inserted a stick.

"You don't even understand the way your own civilization fights and how to survive in space, so you want to know about alien civilizations?" Some people don't like Qin Fei's stick very much.

Qin Fei didn't look back, "The old ancestor said that only by knowing each other and knowing oneself can one not be defeated in a hundred battles." Look, you need to know each other first, and then you know yourself. It is not said that you can understand your enemy before you know yourself. Right. ”

“…… ......" Shangguan Boyun looked at Qin Fei and already felt a headache, this guy is definitely not a worry-free master; None of these newcomers are worry-free. Although it is said that knowing one's opponent and knowing oneself can survive a hundred battles, but that is what the general said - as a general, a really good general, who does not know his own subordinates. In other words, before saying this, Sun Tzu already knew about his subordinates! Although this premise is not spoken, you cannot ignore it.

But it makes sense to take out such a sentence alone......

Qin Fei immediately stopped speaking and made a gesture of listening.

Shangguan Boyun smiled, directly ignored Qin Fei, and continued the original topic. "It's good for us to be studious, but we can't be ambitious.

Let's talk about the spaceship first, the spaceship is very powerful, but it has a weakness, and that is bulky! It is powerful because it is bulky, but it is also limited because it is bulky. Ships are easily sniped in space. Therefore, in real combat, the performance of mechs often cannot be ignored.

Because of its small size, flexibility, and single-player control, the mech becomes the main force of assault in battle.

In interstellar battles. Battleships can only be counted as half of the main force. Because ships are expensive to build, scarce in number, and very bulky and prone to fire.

Also, in today's interstellar battles, there are about sixty percent of the battles. It's still a battle that takes place on the planet; Twenty percent of the battles take place in the starry sky near the planet; Only about two percent, it was a battle between battleships. So the mecha is the other half of the main force.

In fact, a warship is an aircraft carrier, and a mecha is a fighter, and there is no fixed method of how to use it, only to pay equal attention to the two and cooperate with each other.

Actually, for any life. The planet is the ultimate foundation. ”

"The battleship is so bulky, wouldn't it be nice to add engines?" Someone asked. Of course, such a "simple" question obviously would not have been asked by Qin Fei. Qin Fei turned his head to see that it was a person named "Diao Wenjie", who was a group of Qin Fei's seniors, but he was Qin Fei's senior.

Shangguan Boyun was still patient, and explained little by little: "Let's talk about the power system of the spaceship, and of course, the main power technology of the current earth civilization.

In fact, the technology we use is plasma engine and plasma engine.

Plasma engines use high pressure ionization to work on the working medium. The working medium is mainly water, because the water does not clog the engine outlet and adhere to the engine blades with residues such as dirt.

Under the ionization of ultra-high voltage. Water expands to steam, and steam expands to an ionic state, and the volume expands more than 10 million times. In this way, with a little water and electricity, the engine can provide up to several tons, dozens of tons of thrust. The most powerful spacecraft use plasma engines to provide more than 5,000 tons of thrust. It is said that the latest research of our military's soon-to-be-successful plasma engine has a thrust of more than 10,000 tons.

At present, the plasma engine technology is mainly hydrogen-oxygen combustion and plasma-power hybrid technology; After the combustion of hydrogen and oxygen, it can release huge heat and form a huge volume of high-temperature steam; The vapor continues to enter the ionization chamber to be ionized, forming a plasma ejected out.

In fact, storing hydrogen and oxygen itself is an energy storage technology. Coupled with nano battery technology, etc., it can allow mecha to gain great power. It's also our most widely used power technology and system.

However, the plasma engine has a disadvantage, that is, the consumption of the working medium is very considerable. Hundreds of kilograms of hydrogen and oxygen can be consumed in one hour. It is clearly not enough to meet the needs of the spacecraft for a long time; Because spaceships often work for several years, there is no place in space to replenish water and other working media.

To compensate for the lack of plasma engines, we used plasma engines on the spacecraft.

The plasma engine uses nuclear energy technology to reflect the ions and particles generated during the generation of nuclear energy. Nowadays we can even reconcile the light and heat formed during the reaction. It is also reflected. Small plasma engines for satellites and probes can provide a reaction force of a few grams and no more than one kilogram. Even the large plasma engines used on the spacecraft could hardly provide thrust of more than 100 kilograms of reaction force.

But the plasma engine has an advantage, that is, the requirements for the working medium, which are basically zero. Because the fuel of the nuclear reaction itself is the working medium. And in interstellar space, we can also capture isotopes of hydrogen. Such as tritium, deuterium, and deuterium, these are all very important nuclear fuels. It's thin and almost non-existent in space, but it's still captured. In addition, meteorite fragments can often be found in space, and some nuclear materials can be extracted.

The plasma engine can work continuously for several years, and theoretically can propel the spacecraft to sub-light speeds.

It can be summed up like this. The power of the mecha is mainly plasma power, and this alone is enough. The main power of the spacecraft is the plasma engine, but the plasma engine is also indispensable, and both are needed. ”

"Captain, you haven't said why you can't add engines." Diao Wenjie continued to "remind".

"I know!" Shangguan Bowen's tone was a little annoyed, Lao Tzu has said this, you still don't know, you are actually an elite? You're an elite! Who made you pass!

But now that you're on the ship, it's impossible to stop. What is the estimated relationship; Although the military is against it, Huaxia is a humane society, and this thing is still unavoidable. (To be continued.) )
