Since I Was a Special Soldier

There are many records about Princess Wencheng in history, but almost no one knows the origin of Princess Wencheng, and there is no detailed statement so far. It is even possible that Princess Wencheng is a daughter of Li’s collateral family or not. It is possible for a maidservant to adopt a goddaughter.

　　 These all explain one point, don't think about contracts or the like, it's useless, big fists are the truth.

　　All contracts are forced choices made when the two parties cannot physically convince each other.

This is the current situation for humans. There are more than two hundred countries on a planet. These countries will conquer each other, but if one day, suddenly an alien civilization appears in front of the earth, and if humans do not unite, they will all be destroyed. wipe out.

At this time, all racial contradictions and belief contradictions must be put to the end. I dare not say that the earth can quickly unify into a country or a federation, but at the very least, a united front will be formed in a very short time. There is absolutely no problem.

　　If the two sides continue to confront each other and fight for a long enough time, then it is logical that the earth will be unified into a federal state.

　　 There is no pressure, everything is in vain, unless the technological level of one of the countries can suddenly rise to the point where it kills all other countries.

　　 Even so, let’s be honest, let the country choose at present, the country will not choose to engage in unification or alliance.

　　Isn’t the development of Daqin and Song Dynasty popular in the world? Going bigger, isn't Mars fragrant when developing the moon?

　　 When other countries are lagging behind to a certain extent, they will infiltrate the culture step by step, and finally eliminate the other party’s culture, it will be difficult for the other party not to blend in.

　　Sometimes, it’s like that with each other.

　　 The life span of human beings is too short. With a history of more than one hundred years, if there are sufficiently wise leaders to make some long-term plans, it will only take two or three generations to eliminate the other’s culture.

　　 Isn’t there a lot of examples in China? Those Fei Qing who kneel down and can't get up again are too many. The contract is only 99 years, but in fact it is only 156 years.

　　 Therefore, Jiang Yanhai's design at this moment is more about how to return between space and the ground, and the design of spacecraft in space.

　　 These designs can be said to be unprecedented, and there is no example to consult, because these designs are not only related to a spacecraft issue. A spaceship must have a complete environmental adaptation system, and humans consume resources every day.

　　 This is not just a design of a spacecraft, it can be solved by providing enough power.

If the spacecraft’s own internal circulation system cannot be solved, or not solved, at least it is like a source of water, and the air can be solved by at least 50% through internal circulation, then it will have the real long-term recycling and the possibility of mutual development between planets. sex.

　　 Next is the construction of bases on each planet, etc., all of which need to be considered.

　　 Energy only solves the most basic, and there are still many, many remaining problems.

　　 But at the very least, China has reached this point, hasn’t it?

　　 We are no longer just a problem of detection, we are ready to take this step.

　　Waiting for the appearance of this mechanical octopus, Jiang Yanhai is constantly simulating and manufacturing these space planes moving between the ground and the space in the fantasy simulation program.

　　If you have enough power, you can really do not need to be like a rocket, you must reach the first cosmic speed in a short time to get rid of gravity.

　　 After entering space, where the air is thin, at this time, if enough thrust is provided, it will be easier to accelerate above the first cosmic speed.

　　 But how to choose between the two is difficult.

　　 Because you continue to give the aircraft a fixed thrust, even if it is as fast as a human walking, it can leave the earth. But the fuel and energy that continue to be consumed like this is undoubtedly very huge.

　　It is impossible for a rocket to carry so much fuel, so the rocket must use the fastest speed to increase the flight speed, but the weight of the transported object must be taken into account, so there must be a qualified choice in the middle.

In fact, if there is controllable nuclear fusion, this is different. It is like the mainstream ion thrusters in the world are electromagnetic, which is a concept with electromagnetic railguns, which accelerates plasma to a certain extent through a magnetic field. The ultra-high speed, and then ejected from the nozzle, thereby bringing thrust.

　　 But because all the satellites and spacecraft can provide limited electric power, the thrust that consumes electric power to provide the magnetic field to generate thrust is naturally extremely limited.

At present, it is only useful in space, and in space it is basically used for steering. Only some probes released outside the solar system will use such a thing to operate the main thrust, because there is enough long Time allows it to continue to run. At the end, its speed can also reach a very high speed~www.readwn.com~ But there is another type of ion thruster, the arc heating type, which is actually two A high-temperature arc is formed between the electrodes to heat the gas. After the gas enters the compression section of the anode nozzle, the gas is heated by the arc to a high temperature above 10,000K, that is, ionization occurs at a high temperature above 5,000 degrees Celsius.

　　 Then the gas enters the anode nozzle and expands shortly, and the expansion accelerates above supersonic speed, and finally it is ejected at high speed to form thrust.

　　The arc-heated ion thruster has great development prospects. Although it is lower than the electromagnetic thrust\power ratio, it is many times higher than the chemical formula.

　　 In addition, its simple structure, low operating voltage and long life are all advantages.

　　 When the question is said here, everyone should understand one thing, that is, after controlled nuclear fusion, what is this arc-heated ion thruster? This thing also needs electric discharge heating, but don't forget the controllable nuclear fusion, it has extremely terrifying high temperature itself! Just say how many degrees Celsius you want!

　　 Its core temperature can reach 100 million degrees Celsius! If the temperature of controllable nuclear fusion is used for fusion reaction and power generation, its temperature can also heat the air by the way and accelerate the propulsion of ions. This is the best of both worlds.

　　 Otherwise, why controlled nuclear fusion is the most important invention of mankind.

　　 And now, what Jiang Yanhai is doing is how to reasonably miniaturize controllable nuclear fusion.

　　 If it turns into a sci-fi movie like in a sci-fi movie, a core the size of a robot can be used by it, then humans cannot currently do it.

　　 But if you enlarge it to a certain volume, for example, within a huge volume like the An 225, to be honest, it can actually be done.
